Green bean casserole is typically made with ingredients that include green beans, fresh mushrooms, French fried onions and cream of mushroom soup. It's easy to make and can be ready in about 30 minutes.
One recipe for green bean casserole is Paula Deen's recipe on the Food Network. It requires butter, fresh onions, mushrooms and green beans, French fried onion rings and cheddar cheese. Melt the butter and saute the mushrooms and onions, then boil the beans in chicken broth. Mix everything into a greased baking dish and bake at 350 F for 30 minutes, adding the cheddar on top for the final 10 minutes of baking. Make sure the cheese is completely melted before removing the dish from the oven.
Campbell's Kitchen has a slightly simpler version of this classic casserole. Combine 1 can of Campbell condensed cream of mushroom soup with milk, soy sauce, black pepper, beans and 2/3 cup onions in a 1 1/2-quart casserole dish. Then, bake at 350 F. for 25 minutes or until the bean mixture is hot and bubbling. Stir the bean mixture and sprinkle with more onions. Bake for an additional 5 minutes at 350 F or until the onions are golden brown. This recipe serves six.
