How to Use a Pizza Stone on a Gas Grill? | Brick-Oven Crust at Home

Preheat your pizza stone on a gas grill with the lid closed, then slide the pizza on and bake until the crust browns and the cheese bubbles.

Using a pizza stone on a gas grill is the simplest way to pull off a crispy, brick-oven-style crust without owning an outdoor oven. The key is treating the stone as part of the grill itself: it heats slowly with the barbecue, holds that heat through the bake, and gives the dough direct contact with a scorching surface. One wrong move — like putting the pizza on before the stone is fully hot — gives you a pale, soggy base.

Here’s how to get it right on the first try, from preheating to the moment you pull a blistered pie off the grate.

Set Up the Stone Before You Light the Grill

Place the cold pizza stone directly on the grill grate, centered over the indirect zone rather than straight above the hottest burner. Napoleon’s guide advises setting the stone on the cooking grids while the barbecue is cold, and Weber’s instructions for its premium gas models specify the indirect area of the grill for even heat distribution. Preheating together is the whole point: the stone warms gradually with the grill, which prevents the thermal shock that cracks ceramic.

Leave the stone in place while the grill heats, and keep the lid closed the entire time. Do not turn on a sear burner with the stone installed — Weber’s own sheet for its Glazed Baking Stone warns against it, since concentrated direct flame can damage the stone and scorch the base.

Preheat to the Right Temperature

Target the hottest setting your grill allows for the stone, then give it time to soak. Reputable guidance varies by system: Napoleon’s guide suggests around 300°C (roughly 570°F), while Weber’s baking-stone instructions call for preheating at indirect medium-high heat, between 230°C and 260°C (450°F–500°F). Some stone systems run even hotter, up to 500°F–700°F, but the goal remains the same: the stone should be ripping hot before any dough touches it.

Preheat time depends on your grill and target temperature. Weber’s gas-grill instruction sheet says 15–20 minutes; other reputable guides allow 30–45 minutes for the stone to reach full temperature. When in doubt, err long — a fully saturated stone delivers the crisp bottom crust you’re after, and a barely-warm one just steams the dough.

The table below summarizes the ranges from the major manufacturers:

Launch the Pizza and Bake With the Lid Down

Prep your pizza on a peel while the stone heats. Napoleon advises dusting the peel with cornmeal or laying down parchment trimmed to the stone’s size — either one keeps the dough from sticking and ensures a clean slide onto the hot surface. Assemble the pie, give the peel a quick shake to confirm it moves freely, then slide it onto the stone in one smooth motion.

Close the lid immediately and let the trapped heat work. Baking times vary with crust thickness and stone temperature: Napoleon cites 5–10 minutes, while Weber’s guidance lands around 7–9 minutes, and other reputable sources range from 8 to 12 minutes. Watch for the two visual cues that matter — a browned, blistered crust and bubbling, slightly charred cheese. Rotate the pizza once halfway through if your grill has hot spots, then pull it off with the peel.

Cool and Clean the Stone Without Cracking It

Leave the stone on the grill to cool completely after baking — never lift it while hot, and never move it straight to a countertop or sink. The sudden temperature change is what cracks or shatters ceramic stones. Weber’s instruction sheet echoes this, warning against exposing the stone to cold shock.

For cleaning, Napoleon’s guide says a dry cloth is usually enough; if the surface needs more, use a damp cloth and skip the cleaning agents. Don’t submerge the stone in water, and don’t scrub it with soap — the porous ceramic absorbs both, and the residue can flavor your next pizza.
