The Big Green Egg Baking Stone XL turns your XL EGG into a reliable outdoor oven for pizzas, breads, pastries and desserts. Made from high-quality ceramic, it absorbs and holds heat to create an even cooking surface, helping you get crisp pizza bases and consistent bakes. Use it with the convEGGtor® for indirect cooking and steady temperatures, whether you’re doing a quick pizza night or slow-baking sourdough.
