Is Quiche a Casserole or a Pie?

Quiche is a pie!

A casserole is a dish in which food, such as stew, is generally baked with a lid. A pie is a food not baked with a lid. So basically, one of the big differences is that one has a lid and the other does not.

Both quiches and casseroles can be made from various foods that include meats and vegetables. We often think of pies as a dessert but casseroles can be desserts too.
