Best pizza stone for outdoor oven: Ooni and wood fire picks 2026

Pizza stones for outdoor ovens are evaluated by maximum temperature rating (outdoor wood-fired ovens reach 700F to 900F, far above standard oven ratings), material (cordierite handles extreme heat better than standard ceramic), whether the stone fits the specific outdoor oven model (Ooni, Gozney) and price.

Questions people ask

What temperature does an outdoor pizza oven reach?

Outdoor pizza ovens reach higher temperatures than home ovens. Ooni Koda 12 (gas) reaches approximately 950F at the stone surface. Ooni Karu 12 (wood or charcoal) reaches 950F. Gozney Roccbox (gas or wood) reaches approximately 950F to 1000F. Authentic Neapolitan pizza ovens run at 800F to 900F for a 60 to 90-second bake. A home oven typically maxes at 500F to 550F, and a pizza stone or steel at that temperature produces a 5 to 12-minute bake. The higher temperature of outdoor ovens produces the characteristic blistered leopard-spotted crust of Neapolitan pizza that is not achievable in a standard home oven.

Can you use a regular pizza stone in an Ooni?

A regular cordierite pizza stone can be used in an Ooni oven if it is rated for high temperatures and sized correctly for the oven model. Standard home oven cordierite stones (Old Stone at $45) are rated to 500F and will crack in an Ooni at 950F. High-temperature cordierite stones (Unicook at $30 with a 1450F rating) can withstand Ooni temperatures. For an exact fit, Ooni's OEM stone at $60 is the safest option: it is dimensioned and rated specifically for each Ooni model. The Ooni OEM stone is also the right thickness for the oven's floor geometry.

How do I clean an outdoor pizza oven stone?

An outdoor pizza oven stone is cleaned by the same method as a home oven stone: no water, no soap, no soaking. After the oven cools, scrape off food residue with a bench scraper or stiff brush. For outdoor pizza ovens used at 900F+, most food residue carbonizes during use and can be brushed away as ash. The high oven temperature is self-cleaning in that most organic residue burns off completely. For stubborn spots, a dry stiff brush or a damp cloth (on a fully cold stone) is sufficient. Never spray water on a hot outdoor pizza oven stone.
