The allure of a flat top grill, also known as a griddle, is undeniable. Its versatility allows for cooking everything from pancakes and eggs to fajitas and smash burgers with unparalleled ease. But what if you already own a gas grill? Is it possible to achieve that coveted flat top cooking surface without investing in an entirely new appliance? The answer, thankfully, is yes, with caveats. Let’s dive deep into the world of gas grill griddle conversions.
Understanding the Appeal of Flat Top Grills
Flat top grills offer a unique cooking experience compared to traditional grilling. The smooth, even surface distributes heat more uniformly, eliminating hot spots and allowing for consistent cooking across the entire area. This is particularly advantageous for foods that might fall through grill grates or require a delicate touch.
Think about it: the ability to cook scrambled eggs, bacon, or even stir-fry on your outdoor cooking station opens up a whole new realm of culinary possibilities. The high, consistent heat allows for perfect searing, creating a delicious crust on meats and vegetables. The edges retain drippings and oils, adding flavor and preventing dryness. This is a reason that flat top grills have become increasingly popular among both home cooks and professional chefs.
The Gas Grill Griddle Conversion: Options and Considerations
Converting your gas grill into a flat top is generally achieved by placing a griddle plate on top of the existing grill grates. This plate acts as a barrier, creating a smooth, even cooking surface. However, not all gas grills are created equal, and the success of the conversion depends on several factors.
Griddle Plate Materials
The material of the griddle plate is crucial for heat distribution, durability, and ease of maintenance. Common materials include cast iron, stainless steel, and carbon steel.
Cast Iron: Cast iron is known for its excellent heat retention and even heat distribution. It’s a popular choice for griddle plates because it can maintain a consistent temperature even when adding cold food. However, cast iron requires seasoning to prevent rust and can be heavy and prone to cracking if not properly cared for.
Stainless Steel: Stainless steel is durable, rust-resistant, and easy to clean. While it doesn’t retain heat as well as cast iron, it heats up quickly and provides a smooth cooking surface. Stainless steel griddle plates are generally lighter than cast iron and require less maintenance. Look for thicker gauges of stainless steel for better heat distribution.
Carbon Steel: Carbon steel offers a good balance between heat retention, durability, and weight. It heats up quickly and evenly, similar to cast iron, but is lighter and less prone to cracking. Like cast iron, carbon steel requires seasoning to prevent rust, but it is generally easier to maintain.
Sizing and Fit
The size and fit of the griddle plate are critical for safety and efficient cooking. The plate should cover as much of the grill surface as possible without obstructing the burners or vents. Overhanging griddle plates can be dangerous, creating uneven heating and potential fire hazards.
Measure your grill’s cooking surface carefully before purchasing a griddle plate. Many manufacturers offer griddle plates specifically designed for certain grill models. If you cannot find a custom fit, choose a universal griddle plate that is slightly smaller than the grill surface. You may even be able to get one custom-made to your specifications if you are willing to pay more.
Heat Distribution Challenges
Gas grills are designed to distribute heat through open flames, which can create uneven heating when used with a griddle plate. The areas directly above the burners will be hotter than the areas between them. This can be mitigated by using a thicker griddle plate, which helps distribute heat more evenly. It also helps to preheat the griddle for a longer period, allowing the heat to spread throughout the plate.
Also, consider the burner configuration of your grill. Grills with multiple burners that run perpendicular to each other will provide more even heat distribution than grills with fewer, parallel burners.
Grease Management
Flat top grills typically have a grease trap to collect drippings and prevent flare-ups. When converting a gas grill, it’s essential to consider how you will manage grease. Some griddle plates come with built-in grease traps that direct drippings into a removable container.
If your griddle plate doesn’t have a grease trap, you can improvise by placing a heat-resistant container underneath the plate to catch drippings. Be sure to monitor the container and empty it regularly to prevent overflowing and potential fire hazards. You might also need to use aluminum foil to direct grease to the collection point.
The Conversion Process: Step-by-Step
Converting your gas grill into a flat top is a relatively simple process, but it requires careful planning and execution. Here’s a step-by-step guide:
-
Clean Your Grill: Thoroughly clean your gas grill, removing any debris or grease buildup. This will ensure that the griddle plate sits evenly and that there are no flare-ups caused by accumulated grease.

This is especially beneficial for items like eggs, vegetables, and finely chopped ingredients.
Furthermore, the solid surface of a griddle retains heat more effectively, allowing for searing and even cooking across the entire surface. This is ideal for achieving consistent results and developing flavorful crusts. The griddle’s edge also acts as a barrier, containing juices and sauces, making cleanup easier and preventing flare-ups.
Will putting a griddle on my gas grill damage it?
No, using a griddle on your gas grill should not damage it, provided you use it correctly and responsibly. Griddles are designed to withstand high temperatures and distribute heat evenly, protecting your grill burners from direct exposure to food and grease.
However, it’s crucial to choose a griddle made from high-quality materials like cast iron or stainless steel and to clean it regularly to prevent buildup. Excessive grease accumulation can lead to flare-ups and potential damage to the grill’s components over time. Also, avoid using excessive force or dropping the griddle, which could damage both the griddle and the grill.
What materials are best for griddles designed for gas grills?
The two most popular materials for griddles intended for use on gas grills are cast iron and stainless steel. Each offers its own set of advantages and disadvantages. Cast iron is known for its excellent heat retention and even heat distribution, making it ideal for searing and achieving consistent cooking temperatures.
Stainless steel is favored for its durability, rust resistance, and ease of cleaning. While it may not retain heat as effectively as cast iron, stainless steel griddles still provide a reliable cooking surface and are less prone to sticking when properly seasoned. Ultimately, the best material depends on your individual cooking preferences and maintenance habits.
How do I properly season a griddle before using it on my gas grill?
Seasoning a griddle is crucial for creating a non-stick surface and preventing rust. The process involves applying a thin layer of oil and baking it onto the griddle at a high temperature. For a cast iron griddle, start by thoroughly cleaning it with soap and water, then drying it completely. Apply a thin, even coat of cooking oil (such as canola or vegetable oil) to all surfaces, including the underside.
Place the griddle upside down on your gas grill over medium heat for about an hour, or until the oil has polymerized and formed a hard, dark layer. Let the griddle cool completely before using it. Repeat this process several times to build up a strong, non-stick seasoning. For stainless steel, the process is similar, but may require fewer applications.
How do I clean a griddle used on a gas grill?
Cleaning your griddle properly after each use will prolong its lifespan and maintain its performance. After cooking, use a scraper or spatula to remove any food residue while the griddle is still warm. Then, pour a small amount of water onto the hot surface to help loosen any stubborn bits.
Use a scraper or grill brush to thoroughly clean the entire surface, being careful not to scratch the griddle. Once the griddle has cooled, wipe it down with a clean cloth or paper towel. For cast iron griddles, apply a thin layer of oil to prevent rust. For stainless steel, a quick wipe down is usually sufficient.
Will using a griddle on a gas grill affect the grill’s warranty?
Using a griddle on your gas grill is unlikely to void the warranty, as long as you are using it as intended and following the manufacturer’s instructions. Most gas grill warranties cover defects in materials and workmanship, not damage caused by misuse or negligence.
However, it’s always a good idea to review your grill’s warranty terms and conditions to be certain. If you’re concerned, contact the grill manufacturer directly to confirm whether using a griddle will impact your warranty coverage. Also, be mindful of excessive grease buildup or overheating, which could potentially lead to issues that might not be covered under warranty.
