Lobster casserole
A casserole is a kind of large, deep pan or bowl used for cooking a variety of dishes in the oven; it is also a category of foods cooked in such a vessel. To distinguish the two uses, the pan can be called a "casserole dish" or "casserole pan", whereas the food is simply "a casserole". The same pan is often used both for cooking and for serving. Baked dishes have existed for thousands of years. Early casserole recipes consisted of rice that was pounded, pressed, and filled with a savoury mixture of meats such as chicken or sweetbread. Sometime around the 1870s the casserole seems to have taken on its current definition. Cooking in earthenware containers has always been common in most cultures, but the idea of casserole cooking as a one-dish meal became popular in the United States in the twentieth century, especially in the 1950s when new forms of lightweight metal and glass cookware appeared on the market. By the 1970s casseroles took on a less-than-sophisticated image. Culinary experts, such as John F. Mariani, attribute this to the beginning of the dark ages of American culinary culture.
