Why You Need an Outdoor Flat Grill
Traditional grates are great for burgers and steaks, but they leave a lot of cooking territory uncovered — literally. Small items like diced vegetables, eggs, and shrimp fall through the bars. Flat grills eliminate that problem entirely with a solid cooking surface that holds everything. The flat surface also delivers a Maillard reaction browning that grates can't replicate. Every inch of food stays in contact with the hot steel, creating an all-over crust rather than just grill marks. The result is more flavor, better texture, and more consistent results across the board.
Outdoor flat grills are ideal for families, because you can cook multiple food items simultaneously in different zones. Scrambled eggs on one side, bacon on another, and hash browns filling the rest of the surface — all at once, all ready together.
How Outdoor Flat Grills Work
Outdoor flat grills use propane burners positioned beneath a heavy steel or cast iron griddle plate. The burners heat the plate from below, and the thick metal distributes that heat evenly across the entire cooking surface. Most griddles divide the burners into independently controlled zones. You can run one zone at high heat for searing while keeping another zone at medium for keeping food warm. This flexibility makes outdoor flat grills exceptionally versatile for outdoor cooking. The grease management system channels excess fat away from the cooking surface into a removable drip tray. This keeps the surface clean during use and makes post-cook cleanup much faster than with traditional grill grates.
Benefits of Using an Outdoor Flat Grill
Outdoor flat grills heat up fast — most models reach cooking temperature in 8-10 minutes. That speed is a major advantage over charcoal setups, which can take 20-30 minutes to reach the right temperature for grilling. The solid cooking surface prevents flare-ups caused by dripping fat igniting on open flames. This means you get consistent results without the unpredictable heat spikes that char food on traditional grill grates. Cleanup is dramatically simpler on a flat griddle. After cooking, heat the surface, add a little water, and scrape clean with a metal spatula. There are no grates to scrub or remove, and the grease management tray catches everything for easy disposal.
How to Choose an Outdoor Flat Grill
Cooking surface area is the most important spec to consider. For a family of four, aim for at least 400 square inches. If you regularly cook for larger groups or want to handle full outdoor cooking sessions without batching, 600 square inches or more gives you the room you need. BTU output determines how fast the griddle heats and how well it recovers after you add cold food. More BTUs are especially important for high-heat searing. Most outdoor flat grills in this guide fall between 30,000 and 62,000 BTU — enough for nearly any outdoor cooking task. Consider portability if you plan to take your griddle to tailgates, campsites, or events. Some models convert from a cart-mounted station to a tabletop unit.
Others include built-in wheels for moving around the patio. If the griddle stays in one backyard spot, a larger, heavier unit with a hood and storage shelves may be the better investment.
Griddle plate thickness affects heat retention and durability. Thicker plates — 4mm or more — hold temperature better when you load them with cold food, and they tend to develop a more durable non-stick patina over time. Thinner plates are lighter and heat faster but can develop hot spots more easily. Finally, look at the overall build quality of the cart, shelves, and frame. Stainless steel burners resist corrosion better than standard steel in outdoor environments. Folding or removable side shelves add useful workspace and make the unit easier to store or transport.

Blackstone 28 Inch Original Omnivore Griddle 2206
- Omnivore Griddle Plate Technology for even heating
- Two independently controlled cooking zones
- 527 square inch cooking surface
- Integrated side shelf with tool hooks
- Rear grease management system
The Blackstone 28 Inch Original Omnivore Griddle earns its Best Overall designation by combining a generous 527-square-inch cooking surface with Blackstone's proprietary Omnivore Griddle Plate Technology. The plate heats remarkably evenly across both cooking zones, eliminating the hot-spot issues common in budget flat grills. Two independently controlled burner zones let you cook at different temperatures on the same surface. This is especially useful for outdoor grilling sessions where you need a high-heat searing zone alongside a lower-heat holding zone for finished food.
The rear grease management system keeps drippings away from the burners and away from the cook, channeling fat into a removable tray that's easy to empty and clean. The integrated side shelf and tool hooks add workspace without expanding the overall footprint significantly.

See at AmazonFuel Types and Newer Griddle Features
Natural Gas vs. Propane
Most flat top grills run on propane, but some models -- especially larger built-in units -- support a natural gas conversion. Natural gas means unlimited run time with no tank to swap out, but it requires a dedicated gas line plumbed to the grill's location, which usually means a professional installation rather than a simple backyard setup.
Ceramic-Coated vs. Traditional Steel
Newer griddles increasingly use a ceramic-coated cooking surface instead of bare carbon steel. Ceramic coatings arrive pre-seasoned and food releases from them easily from day one, skipping the initial seasoning process altogether. The tradeoff is that ceramic coatings can chip if scraped aggressively with metal tools, so they need slightly gentler cleaning than a traditional steel plate.
Built-In Griddles for Outdoor Kitchens
If you're building a permanent outdoor kitchen island rather than buying a portable unit, look at built-in flat top griddles designed to drop into a cutout, with the gas line and controls tucked underneath the counter. They give up the portability of a cart model in exchange for a finished, seamless look.
Weight-Based Propane Gauges
Some premium propane models now include a built-in tank scale or weight-based fuel gauge, so you can check how much propane is left without disconnecting the tank and guessing. It's a small feature, but a useful one if you tend to run out of propane mid-cook without warning.
Melting Domes and Accessories
A melting dome (sometimes called a steaming dome) is a metal cover you set over food directly on the griddle surface to trap heat and steam. It's the standard way to melt cheese onto a smash burger or steam vegetables on a flat top, since there's no lid covering the cooking surface the way there is on a kettle grill.
Pre-Seasoned Plates
Some manufacturers now sell factory pre-seasoned or rust-resistant treated plates that are ready to cook on right out of the box, skipping the multi-round oil-and-heat seasoning process entirely. It's a genuine convenience if you don't want to deal with seasoning, though many griddle cooks still prefer building their own seasoning layer from scratch for a more customized non-stick finish over time.
What is an outdoor flat grill?
An outdoor flat grill — also called a griddle — is a propane-powered cooking station with a solid, flat metal cooking surface instead of traditional grates. The flat surface retains heat evenly and allows you to cook foods that would fall through standard grill bars, including eggs, pancakes, and diced vegetables.
How do I season a new outdoor flat grill?
Apply a thin, even coat of high-smoke-point oil — such as flaxseed, canola, or avocado oil — to the clean cooking surface. Heat the griddle on high until the oil smokes and polymerizes into a dark layer. Let it cool and repeat 2-3 times before cooking on it.
What can I cook on an outdoor flat grill?
Outdoor flat grills are exceptionally versatile. You can cook breakfast items like eggs, bacon, and pancakes; lunch and dinner staples like burgers, smash patties, and chicken; and side dishes like fried rice, stir-fried vegetables, and quesadillas — often all at the same time across different heat zones.
How do I clean an outdoor flat grill?
After cooking, while the griddle is still hot, pour a small amount of water on the surface and scrape it with a metal spatula. The steam loosens food debris. Wipe dry, apply a thin layer of oil, and let it cool. Empty the grease collection tray after each use to prevent buildup and odor.
How many BTUs do I need for an outdoor flat grill?
For casual home use, 30,000-40,000 BTU is sufficient for most families. If you cook for large groups regularly, or if you prioritize fast heat-up times and high-temperature searing, look for models with 50,000-62,000 BTU. More BTU also helps the griddle recover temperature quickly after adding cold food.
Can I use an outdoor flat grill for camping?
Yes, many outdoor flat grills are designed with portability in mind. The SKOK 3 Burner in this guide is a strong camping option. Some models, like the Royal Gourmet PD4001, convert from cart-mounted to tabletop configuration for easy use at campsites. Look for compact dimensions and manageable weight if camping portability is a priority.
What is the difference between a flat grill and a regular grill?
A regular grill uses open metal grates over a heat source, allowing fat to drip down and creating grill marks. A flat grill uses a solid surface, which retains drippings and delivers all-over contact browning instead of grill marks. Flat grills are better for delicate foods and large batches; regular grills excel at charred, smoky flavors.
Do outdoor flat grills cause flare-ups?
Outdoor flat grills produce far fewer flare-ups than traditional grates because the solid cooking surface prevents fat from dripping directly onto open flames. A quality grease management system channels drippings away from the burners, further reducing the risk. This makes flat grills a safer and more consistent choice for high-fat foods like bacon and smash burgers.
How large of a flat grill do I need?
For 2-4 people, 300-400 square inches is sufficient for everyday outdoor cooking. For families of 5-8, or for entertaining, aim for 500-600 square inches. If you regularly cook for more than eight people or want to cook an entire meal simultaneously without batching, a larger hooded 36-inch griddle is worth considering.
Are outdoor flat grills easy to assemble?
Most outdoor flat grills come with step-by-step instructions and clearly labeled parts. Assembly typically takes 30-60 minutes for one person. Some customers find it easier with two people, especially for positioning the griddle top onto the cart frame. All models in this guide include electronic ignition for easy startup after assembly.
