One might confuse casserole with the utensil but that's only part of what it means. A round, steel utensil that is deep in the centre and can be used to store food is also something that can be used to cook food. Oh yes, you read that right. For the unversed, the idea behind a casserole is to cook and serve the food as is i.e. in the same utensil. Usually baked items are made in a casserole, ranging from chicken, fish, meat to vegetables. It can be topped with cheese and other garnishings. The casserole's lid is generally removed and it is made without any cover in an oven. Do you like seafood? There are plenty of fish in the seas (quite literally) that you can try.
