Pizza stones, stone bar pans and baking round stones -- almost every Pampered Chef product with "stone" in the name -- requires seasoning to build up the layer of polymerized fat that prevents sticking. Stoneware self-seasons after repeated use, but you always have a few casualties -- a pizza that won't slide off or a few muffins that won't dislodge from their cups -- in the beginning if you don't prep the surface. Seasoning ensures your first baking experience in Pampered Chef stoneware isn't a sticky one.
Heat the oven to 400 degrees Fahrenheit. Wash the stoneware with hot water and a scrub brush or sponge. The manufacturer does not recommend using soap -- just a good scrub with hot water.
Dry the stoneware with a towel and coat it with a thin layer of vegetable oil. Set the stoneware in the oven.
Bake the stoneware for 30 minutes then turn the oven off. Let the stoneware come to room temperature in the oven, about 2 hours. You can use the stoneware as needed; the stoneware will keep itself seasoned with repeated use.
