8 flat top grills lined up for testing

The outdoor griddle is a hot commodity in the outdoor cooking space, and it's time to determine who makes the best outdoor flat top griddle. We recently put 8 different brands to the test.

Why Trust Our Review

We have personally used every outdoor griddle mentioned in this article. Not only have we used each one, but we also used each one side-by-side so that we could best compare similar qualities. Don't just take my word for it. The evidence is in the pictures and video.

This article was not written by AI; it was written by real humans who have actually used these products.

We have run each outdoor gas griddle through the same series of tests and will let the data speak for itself.

Though the flat top griddles themselves were supplied to us for free for this video and article, none of the manufacturers have paid to be involved or "win" this review.

We are affiliates, however, and will earn a small commission if you purchase any of these gas griddles using our link. That is one of the ways we are able to continue doing what we do, so we do appreciate your support in that way.

How We Tested For The Best Outdoor Griddles

Testing for Hot Spots and Cold Spots

Time to temperature, BTU's, heat zones and more are all fine and good, but here's a test designed to check the evenness of the flat top griddle heat.

We set each grill to 350 degrees as measured by our Thermoworks IR gun, then covered the entire griddle surface with slices of bread. We set the Big and Loud timer to 5 minutes and sat back to smell the toast.

At the 5-minute mark, here's how the toast on each flat top griddle looked.

The Flatrock takes first place with the most even result, followed by the Primate in second place and the Slate in third. The Blackstone rounds out the end in 7th place and the Napoleon takes 8th, in our opinions.

Wind Test

Whenever I use a griddle, it's often while there's a wind blowing outside, so to test wind performance with each griddle we set a fan blowing on high, 20 inches from the griddle surface leveled with the center of the fan at cooking level. We measured the wind speed between 7 and a half to 8 miles per hour for this test.

Each griddle was set to high for 10 minutes, and at the 10 minute mark, we took temperature readings starting 2 inches away from the edge of the griddle. Measurements were taken at 2, 4, 6, 8 and 10 inches, the very middle of the griddle, and the far edge using the Thermoworks weighted griddle thermometer.

The next day, we ran the same test without the fan and logged those numbers as well and charted the difference the fan made to the griddle performance.

We also cooked a pound of bacon on each griddle while the fan was blowing. Here's what we saw from each flat top griddle after we turned the bacon.

The griddles least affected by cooking in the wind included the Steelfire, Flatrock, Primate and Napoleon. The Blackstone and Pit Boss models struggled the most.

Cooking Space

I’m sure you noticed there is a wide range of flat top griddle sizes in our comparison, with the largest being 37" and the smallest coming in just under 28 inches. You can see the breakdown in griddle sizes here, but basically there’s a group of griddles that range from 28-31 inches, and another group that range between 36-37 inches.

The Weber is also available in a larger size, as well as what you see here. 

So what’s the difference in capacity between a 28” and a 37” griddle? Let me show you in pancakes.

Capacity

Melissa made a batch of her homemade buttermilk pancake recipe to see how many we could fit on each griddle. We laid out the exact same (approximately) 4-inch pancakes to calculate the maximum capacity. To be clear, we would never actually cook this many pancakes at a time, so close together, but we're aiming to give you a visual representation of what each flat top *could fit.

Pancake capacity test

The Blackstone and Pit Boss both had space to fit 40 pancakes, followed by the Gridiron Pro, which had space for 32.

The Flatrock, Slate, and Primate all had enough room for 28 pancakes.

While the Steelfire is difficult to really calculate in the same manner with it's oval shape, we estimate 25-26, followed by the Napoleon, with 24 pancakes.

Pancake capacity test

Cooking Height

Cooking height is something to strongly consider if you’re very tall, or more on the petite side. Melissa is 5’2” and I’m 5’11” so what’s comfortable for me probably feels too high for her and vice versa. There's about a 4 inch difference in cooking height between these models, with the Napoleon having the highest cooking position at 38 inches and the Pit Boss with the lowest cooking height at 34 inches high.

This is probably an appropriate time to point out that the Solo Stove Steelfire can be removed from its cart and set on top of a table or counter, making its cooking height flexible.

Low temperature test

We get a lot of questions about how low of a temperature each flat top griddle can run, so we tested each griddle using the Thermoworks weighted griddle thermometer.  

We ignited all of the burners on each griddle, turned them as low as they would go, and set a timer for 15 minutes.

The griddle with the lowest temperature was the Camp Chef Gridiron Pro, with a low of 323°. The second lowest after 15 minutes was the Solo Stove with 349°, and in third place was the Traeger, coming in at 357°.

The griddle with the highest low temperature was the Blackstone, with a low of 450°, over 120 degrees hotter than the winner in this category. Here is the graph of the temperatures for each griddle, going from cold to low for 15 minutes with all burners ignited and set to low.

High Temperature Test

To understand the top level heat for each griddle, we started from a cold griddle and cranked all of the burners up as high as they would go and set a timer for 15 minutes.

The hottest griddle was the Weber, which topped 708° Fahrenheit at the 15-minute mark. The Blackstone came in second with a top heat of 654°, and the Primate comes in third with a high of 646°.

The griddle with the lowest high heat was the Camp Chef Gridiron Pro, with a high of 526°. 

Ambient Temperature Test

At the end of the high-end heat test, we wanted to see how hot the side shelves on each griddle got when set to high.

The griddle with the lowest temperature shelves was the Solo Stove, coming in at 117° when measured at the closest lip to the griddle surface. The second lowest was the Weber, which measured 139°, and the Traeger comes in third with 177° temperatures measured on the side shelves.

bar graph showing ambient temperatures on side shelves

 The griddles with the highest temps on the shelves were the Blackstone at 226° and the Primate, which measured 233° Fahrenheit. There were three griddles that all measured over 200°, so if you decide to go with these models, I'd keep your bottles of BBQ rub away from the inside lip of each shelf, or they could easily melt through the plastic.

What we like:

  • The stainless steel griddle top is a game-changer in this category.. 
  • This cooktop boasts excellent searing ability.
  • Not only does stainless clean more easily, it can also clean more thoroughly than every other griddle in our roundup. The cooktop is lightweight and can be carried over to a sink for a good deep clean whenever needed. Also, it can be washed with soap and water, making this an excellent option for those concerned about food allergies and cross-contamination.
  • Rust is not a concern with this griddle.
  • The two "racetrack" burners provide incredibly even cooking from edge to edge. There are literally no hot or cold spots anywhere on this griddle.
  • Not only can this be a great griddle for your backyard, but it can easily be taken with you for camping or tailgating. The griddle top lifts out of the cart with minimal effort and can be used table or counter top instead.
  • The grease trap is protected from the weather and easy to clean out.
  • Solo Stove offers a 5-year warranty on this flat-top grill. That's impressive and confidence-boosting.

What we don't like:

  • The cart is just ok. It feels a little flimsy. But it does the job.
  • The oval shape does take some getting used to, but it isn't as annoying as you would initially think. The only time it really bothers me is when we're making pancakes and my OCD kicks in, and I can't make nice neat rows while maximizing the space.

The Steelfire can be purchased with or without the cart.

490 square inches

Cooking Height

36.5"

Number of Burners

4-burner 60,000 BTUs

Warranty

4 years

What we like:

  • The Grilla Grills Primate is both a gas griddle and a gas grill in one box. The griddle easily pulls out to replace with stainless steel grill grates. There's even a 2/3 griddle available so that you can have griddle and grill options in place simultaneously if you want.
  • This is the only fully stainless steel cart and lid in the bunch and this unit is solid.
  • The griddle is recessed, protecting the burners from wind so we were able to achieve an even cook on the bacon even with a fan blowing from the side.
  • The 4 year warranty from Grilla Grills gives buyers additional confidence in their purchase.
  • The Primate can easily convert to a built-in griddle with Grilla Grills outdoor kitchen modular pieces.
  • The Grilla Grills Primate gives a pretty even cook from front to back and side to side.
  • It includes a paper towel holder.
  • The Primate is natural gas compatible.

What we don't like:

  • The Primate gives us the much less cooking area than many of the other griddles.
  • I wish the cabinet offered storage space for the griddle top when the grill grates are being utilized. (In contrast, the Primate built-in kitchen cabinet does).
  • The side shelves are pretty small.

If you're trying to decide between a gas grill and a griddle because you only have room for one, the answer is quite simply: Grilla Grills Primate. In my opinion most combo grills fall under "Jack-of-all-trades-master-of-none" but the Primate is definitely an exception. Grilla Grills builds high-quality outdoor cooking appliances and in the case of the Primate, you get two for the price of one.

What we like:

  • I can't say enough good things about the prep and storage space on this Slate griddle. The side shelves are very sizeable and this model includes an extendable side table for even more space.
  • Below the bottom shelf are two plastic tubs with lids to store and protect all of your griddle tools and supplies from the weather.
  • The top of the right side shelf lifts out leaving a hole perfectly sized to hold the storage bins from below.
  • The griddle surface is silky smooth and already seasoned right out of the box.
  • During our bread test the Slate demonstrated even cooking from front to back and side to side.
  • The digital temperature display shows the temperature of the griddle surface.
  • The grease trap is protected from the weather and easy to clean out.
  • Weber offers a 5-year warranty on this flat top grill. 
  • The Slate is natural gas compatible.

What we don't like:

  • While this griddle top is rust-resistant, it is not immune to rust. After storing the Slate over the winter and pulling it back out, there were some small areas of rust that did require some reseasoning.

My favorite thing about the Weber Slate is that the griddle top comes seasoned right out of the box. There’s no coating, so metal utensils are good to go. I really like the bin system underneath providing extra space for storage and the accessory options that can be purchased for the side shelves. I can tell that the people who designed this griddle actually cook on griddles, because the functionality of space was spot on.

Fuel

propane or natural gas

Number of Burners

2 U-shaped burners 18,000 BTUs

Warranty

5 years

What we like:

  • Le Griddle uses 304 Stainless steel construction all throughout.
  • There is a large cast iron plate welded to the bottom of the stainless steel griddle that helps with heat distribution.
  • The removable grease tray sits at the front of the griddle, not interfering at all with the cooking surface.
  • Cleaning the stainless steel griddle is simply done by dropping ice cubes on the hot surface and allowing the steam to break loose the cooked particles.
  • There is a 5-year warranty on the burners and a lifetime warranty on the stainless steel.
  • A cart is available for purchase if you aren't planning on building it into an outdoor kitchen.

What we don't like:

  • The lid must be purchased separately.

We've been using our Le Griddle 30" gas griddle in our outdoor kitchen for about 5 years now. We use it all the time, probably 4-5 times a week, easily. I have utmost confidence that this griddle will last the long haul out there and when you install appliances in an outdoor kitchen you want products that will last. If you're planning to build an outdoor kitchen, I can't recommend the Le Griddle enough for your built-in griddle.

Cooking Height

Number of Burners

3-burner 43,500 BTUs

What we like:

  • We absolutely love the side shelves on the Traeger Flatrock. They are nice and huge when you want them, but fold down easily when you don't. They can also utilize the Traeger pop and lock system for additional storage, though we don't have any of those accessories to demonstrate.
  • The grease bucket on the Flatrock uses the same grease bucket liners used in their pellet grills, so it's substantial in size, which we appreciate. We also love that it's secured nicely under the griddle top and will not be collecting rainwater when the griddle is left uncovered.
  • The griddle is recessed, meaning that this flat top performs flawlessly on a windy day.
  • During our bread test the Flatrock demonstrated even cooking from front to back and side to side.
  • We absolutely love the idea of the propane tank sensor that will help you understand how much propane is left in the tank.
  • There are baffle plates between the burners allowing for 3 distinct zones of cooking.
  • Traeger offers a 5-year warranty on this flat top grill. That's impressive and confidence-boosting.

What we don't like:

  • We have never managed to get our propane tank sensor to work properly, even after multiple calls with customer service and new parts being installed.
  • We don't love the placement of the grease trap hole and find that it sometimes interferes with our cook.

What we like:

  • The included side-burner offers a lot of cooking versatility and options. Adding the side kick grill, pizza oven, or even griddle attachments can really expand this appliance.
  • It is very spacious with 634 square inches of space to cook.
  • This flat-top offers pretty even heat distribution from front to back.
  • The removable grease trap is protected from the elements, safely stored underneath the gas griddle.
  • The side shelves are spacious and can expand functionality with the addition of the magnetic accessories.
  • The Gridiron Pro does a great job of maintaining low temperatures without getting too hot.
  • A natural gas conversion kit is available for this unit.

What we don't like:

  • The Gridiron Pro seems to be impacted by wind, though not as much as the previously tested Gridiron.
  • There seems to be a limit on how hot this flat top can get, and it's noticably lower than the other griddles we tested.

Warranty

What we like:

  • The Rogue Pro Phantom has a stainless steel cooktop.
  • The left side shelf has a pull-out caddy that can hold bottles and ingredients while you cook, as well as a bottle opener.
  • The stainless steel cooktop offers great searing ability and easy cleanup.
  • Rust is not a concern with this griddle.
  • There is a removable warming rack.
  • The Rogue Pro Phantom is available with natural gas.
  • Napoleon offers a 15 year warranty that is certainly impressive.

What we don't like:

  • The front of the griddle is considerably hotter than the back. This is nice for certain types of cooking where you want a cool zone to push food to, but in other things like cooking a whole flight of pancakes, it can be frustrating.
  • When we first used the Rogue Pro we had issues with the stainless cooktop warping considerably when cooking. After reaching out to Napoleon, they sent us a new griddle top, citing a faulty batch of griddles. This new cooktop has NOT warped after a dozen or so uses. I share our experience because if you happen to see the same warping with your new Rogue Pro, please know that's not right (or safe), and Napoleon will make it right. Just reach out to their customer service.

What we like:

  • This Blackstone model includes 2 air fryer drawers and 1 warming drawer in addition to the flat top.
  • With 768 square inches of cooking surface, there's plenty of room to cook a lot of food on this Blackstone.
  • The side shelves both have tool hooks and the ability to slide on additional accessories to add features.
  • The grease drain out the back does not take any space away from the cooking surface.

What we don't like:

  • The grease bucket is exposed to the elements so it will collect rainwater if the griddle is left uncovered.
  • We were surprised by the uneven heating of the cooking surface. It was clearly much hotter in the center than the outer edges of the griddle surface. 
  • The Blackstone griddle struggles to cook evenly in windy conditions.

What we like:

  • It's pretty clever the way the side shelves double as the lid, offering a lot of prep space when cooking.
  • With a cooking surface 37" across, this griddle has a nice and big cooking capacity.
  • This is the most affordable griddle in our roundup.

What we don't like:

  • This Pit Boss gas griddle doesn't perform well on a windy day.
  • The Pit Boss Deluxe struggled to cook evenly showing a particularly hot streak across the middle of the surface.
  • The grease cup is exposed to the elements when the griddle is closed.
  • After being stored in the off season, we opened this griddle up to find mouse poop and rust, requiring a fair amount of work to get it ready and safe for a new season of cooking food.

How To Choose The Best Flat Top Griddle For You

We did a full week of testing 8 griddles and in the process, we were able to conclude what our favorite (or favorites) were from the bunch. The thing is, we don't necessarily use outdoor gas griddles the same way you might. And the things we care about might be different from the things you care about. So you and I might look at the exact same data and reach different conclusions about which flat-top we prefer.

Here are a few questions we recommend asking to help you decide which griddle is right for you.

How much cooking area do I need?

Outdoor gas griddles come in a variety of sizes and it can be difficult to decide what the perfect size might be for you. You don't want to go too big and have a cooking appliance that takes up too much patio space, but you also don't want to go too small, limiting what you can cook on your new griddle.

Before you commit to a particular griddle size, I recommend making a list of 5-10 foods or meals you plan on cooking on your griddle. Does your list consist of mostly single-course foods or do you find that you're wanting to cook full meals?

In our experience, we often run out of space when cooking a full meal on a griddle, so more space is better for us.

What is the heat source for a flat-top grill?

Most flat-top grills on the market are heated by propane or natural gas burners below the griddle surface. These burners can come in all shapes, sizes, and BTUs.

Sometimes the arrangement of burners results in hot spots and cold spots that present challenges when cooking. Other times the arrangement is just right for even cooking front to back and side to side.

When shopping for your next outdoor gas griddle, take a look under the hood to see what the burner situation is.

How is grease managed?

Flat-top cooking often produces grease and food debris that needs a place to go, so manufacturers have designed their griddles to channel grease into some type of removable grease tray. The location of the grease trap varies from griddle to griddle; some in the front, and some in the back. As you compare each grease management system here are some things to consider:

  1. How much cooking surface is lost to the grease trap and does it look like food might accidentally get lost down that hole while cooking? There's nothing worse than accidentally knocking a shrimp down the grease trap.
  2. Is the removable grease tray exposed to the elements? If the griddle is left uncovered and it rains, will the grease tray collect rainwater?
  3. What's the capacity of the grease tray? Will it need to be emptied after every cook?

How will the flat-top grill perform in windy conditions?

Not all outdoor gas griddles perform equally in windy conditions. Many griddles are built with a gap between the griddle surface and the burners below for airflow. These griddles struggle to perform well in windy conditions.

There are some flat-top grills available with a recessed griddle surface, protecting the burners from exposure to the wind. These flat-top griddles perform equally regardless of the wind.

I highly recommend choosing an outdoor griddle that will perform well on a windy day.

How much prep and storage space will I need?

Griddle cooking is typically hot and fast. Emphasis on the fast.

It is important to have all your ducks in a row before you start cooking because you can't generally leave your food on the hot griddle surface and run back inside to grab something. Not only do you need to have all your ingredients and cooking utensils ready, but you also need to have your clean dish or dishes to transfer the cooked food into when it's done cooking.

This is why sufficient shelf space is absolutely critical in my opinion. Unless you want to have to set up a table every time you cook on your griddle, your griddle shelves need to be able to accommodate the tools and ingredients for the job.

Do I need to season my outdoor gas griddle before I use it?

Most carbon steel outdoor griddles will need to be seasoned before use unless clearly labeled "pre-seasoned" in the manual. Stainless steel griddle surfaces do not require seasoning.

The seasoning process will help your griddle develop a non-stick cooking surface as well as help protect your griddle from rust, extending the life of your flat-top grill.

What griddle care and maintenance is required?

Treat your carbon steel griddle surface the same way you would your favorite cast iron pan. Season it with oil (several layers) before first use, don't wash with soap, but instead, use water and an abrasive scrub tool to remove any food debris, and reseason with oil after each use. Failure to reseason your griddle surface after each use may result in rust developing.
