How to Bake Fish

1. Preheat the oven to 450°F. If the fish is covered with a sauce containing milk, eggs, and cheese, cook it at a lower temperature (350°F) to ensure that the proteins in these ingredients do not separate or harden.
2. If the fish is a whole fish, make several cuts in its flesh to ensure that the heat penetrates it thoroughly. The stomach cavity can be stuffed with seasonings such as sliced onions, garlic, thyme, pepper, ginger, or other herbs and spices.
3. Place the fish in a dish and either dot it with butter or margarine, or brush on a little oil.
4. Cover the fish with a selection of thinly sliced vegetables and slices of lemon (or place it on a bed of vegetables).
5. Moisten the fish and vegetables with a white wine or cream sauce.
6. Cook the fish for the appropriate length of time.
