The Masterbuilt Reversible Griddle Insert MB20183725 is a simple way to add extra cooking flexibility to your charcoal grill. Built from heavy cast iron, it gives you a solid, even-heating surface that performs just as well for quick breakfasts as it does for stir-fries, smash burgers or seared meats. The reversible layout provides two distinct options: a smooth flat top for delicate ingredients and high-volume cooking, and a ridged side that delivers pronounced grill lines and enhanced browning.
Because it sits directly over the heat source, the griddle comes up to temperature quickly and stays consistently hot across the entire surface. This makes it ideal when you want to cook multiple items at once without hot and cold spots. The weight and finish of the insert help minimise sticking, improving further as the cast iron develops seasoning over time.
Designed to fit securely into the Masterbuilt Gravity Series 600 and XT charcoal units, as well as the AutoIgnite 545, the insert drops into place without tools and can be swapped out mid-cook if you want to move between conventional grilling and flat-plate cooking. Its generous size makes it practical for families or entertaining, giving you the ability to run full breakfasts, fajitas or burger batches without juggling pans.
For anyone wanting more from their charcoal setup, this insert adds the convenience of a flat-top grill while keeping the flavour and power of live-fire cooking.
