What is a casserole?

A casserole is best described as a dish that is cooked in liquid in the oven. This method typically involves combining a variety of ingredients such as meats, vegetables, and starches, which are then cooked together in a single pot or dish. The liquid used in a casserole, which could be broth, sauce, or water, allows for slow cooking, resulting in tender textures and well-blended flavors.

Casseroles are versatile and can incorporate a range of ingredients, reflecting regional cuisines and personal preferences. The process is largely focused on baking in a covered or uncovered dish, which allows for both moisture retention and, in some cases, browning on the top. This method contrasts with frying, grilling, or pastry techniques, which do not involve the same combination of ingredients or methods of cooking within a liquid medium.
