Crisp and Golden Mac and Cheese Cakes on the Grill
Turn yesterday's leftover macaroni into today's crispy, golden side dish with this easy wood-fired recipe.
Adding a griddle insert to your Charbroil Infrared Grill is one of the most effective ways to increase versatility and flavor. While standard infrared grates are excellent for heating efficiency, a flat top insert allows you to cook small items like eggs and vegetables while sealing in meat juices that usually drip away. For the best performance and longevity, opting for a heavy-duty carbon steel insert over standard cast iron provides superior heat retention and a smoother, non-stick patina over time.
Before buying an accessory, understand how a dedicated flat top surface compares to the standard setup found on most infrared grills.
| Feature | Standard Infrared Grates | Carbon Steel Griddle Insert |
|---|---|---|
| Surface Consistency | Gapped (Food can fall through) | Solid (100% Surface Contact) |
| Sear Quality | Grid marks only | Edge-to-edge crust (Maillard reaction) |
| Juice Retention | Low (Drips onto emitters) | High (Cooks in own juices) |
| Versatility | Steaks, Chops, Burgers | Everything + Eggs, Pancakes, Veggies |
| Durability | Prone to rust if coating chips | Lasts a lifetime with seasoning |
Many grilling enthusiasts eventually migrate from open grates to flat tops (or "plancha" style cooking). The primary reason is flavor density. On a standard Charbroil grate, juices drip down to the infrared emitter. While this creates some smoke, you lose the moisture content inside the meat.
A solid surface insert, specifically one made of high-quality carbon steel, sears the meat in its own rendered fat. This technique creates a deeper, savory crust that open flames simply cannot replicate.
Pro Tip: Treat your carbon steel insert exactly like a cast iron skillet. Avoid soap after the first wash, and always apply a thin layer of oil after cleaning to build a natural non-stick patina.
Not all inserts are created equal. When modifying a Charbroil Infrared Grill, the thickness and material of the insert dictate your cooking success.
While cast iron is traditional, it is brittle and prone to cracking under thermal shock. Carbon steel possesses the heat retention of cast iron but is significantly smoother and more durable. It heats up faster and tolerates higher temperatures without warping, making it the ideal material for high-heat infrared searing.
Yes, universal inserts sit directly on top of your existing grates. However, for the best efficiency, ensure the insert covers enough area to capture the infrared heat from below without blocking airflow entirely. This turns your grill into a dual-purpose outdoor kitchen.

Yes, you can safely place a griddle plate or insert on top of the grates. Ensure it is made of heat-conductive material like carbon steel or cast iron to maximize the infrared heat transfer.
Generally, yes. Carbon steel is smoother, lighter, and less brittle than cast iron, making it easier to season and less likely to crack under high heat.
Keep the surface seasoned by applying a thin layer of high-smoke-point oil (like grape seed oil) after every use. Store the insert in a dry place if you aren't using the grill for extended periods.
