The Ooni Pro is the planet's best open-air cooker, efficient in blazing hard woods, coals, gas, or pellets. Increasing the wood tinder for a surge of intense wood-fired flavor is just one attribute of the Ooni Pro ! Feel like cooking the way your great grandparents did when they first arrived from Italia, then use coals! And gas is always greatest when tailgating. Who needs to worry about natural fires when the game is starting!
