A pizza stone for a grill sits on the grates and turns the lid-down grill into a pizza oven. The stone absorbs heat and holds it, giving a crisper crust than a thin pan could. Cordierite is the usual material because it handles sudden heat without cracking.
The six stones below include round and rectangular designs, a brand-matched Weber stone and a cordierite option sold with a peel. We have not used these products ourselves, so confirm the size, fit on your grill and included accessories on the current listing before buying. Heat claims are the makers’ own.

Care and Setup
- Let the stone heat up with the grill so it does not crack.
- Never use soap, since the stone absorbs it.
- Scrape off baked-on food with a dry scraper.
- Let it cool inside the grill before moving it.
- Store the stone flat and dry, away from damp corners where moisture can seep into it.
Mistakes to Avoid
- Placing a cold stone on a hot grill.
- Using too much oil on the stone.
- Choosing a stone too large for the lid.
- Sliding a wet pizza onto the stone.
- Cleaning a warm stone with cold water, which can cause cracks.
Grill Pizza Stone FAQ
Can I leave the stone in the grill?
Many bakers do, but check with the maker. Keep it dry between uses.
Why does the bottom of my pizza burn?
The stone may be too close to the flame. Use a lower burner setting or raise the stone.
Do I need a peel?
Yes, a peel makes launching safer and easier than using your hands.
Is a stone better than a pan on the grill?
A stone holds heat and wicks moisture from the dough, which usually gives a crisper base than a thin pan. The trade-off is weight and a slower warm-up, so plan your timing.
The Short Version
For a trusted pizza brand, the Pizzacraft ThermaBond. For an easy starter, the Unicook. For Weber systems, the Weber stone. For a kit, the Cuisinart set. For Napoleon grills, the Napoleon stone. For flexible shapes, the Hans Grill.
