The Staub Ceramic 4 Piece Set is the secret to savory casseroles and delicious desserts. The porcelain enamel glaze prevents absorption of moisture during baking, so foods won't dry out. Enjoy gooey mac n' cheese, buttery apple crumble, and moist brownies every time. The set is conveniently stocked with three different sizes and shapes. The 9 by 9-inch Square Covered Baker allows you to bake and serve in the same dish - plus, its lid locks in heat to keep your food warm. The 9-inch Oval Baking Dish is perfect for gratins and crumbles. And the 7.5 by 6-inch rectangular dish is ideal for smaller casseroles.
