A deep pie dish is a type of baking dish that is designed to hold large amounts of filling, typically for pies or other desserts. The term “deep” refers to the fact that these dishes are taller and wider than standard baking dishes, allowing them to accommodate more ingredients without overflowing. This type of dish can be made from a variety of materials such as ceramic, glass, or metal, with each material offering its own unique properties in terms of heat distribution and durability. Deep pie dishes are commonly used for baking pies, but they can also be utilized to make other types of desserts like cobblers, crisps, and tarts.
