One good broccoli rice casserole recipe calls for butter, broccoli, rice, condensed soup, cheese sauce and spices. These ingredients are baked until the casserole is hot and bubbly.
To make a broccoli rice casserole, heat 1/2 cup of butter in a skillet over a medium heat. Add 1 large chopped onion and cook, stirring occasionally, until the onions are tender-crisp. Add a 16-ounce package of chopped frozen broccoli to the pan, and cook it until it is tender-crisp. Stir in 1/3 cup of milk, one 10 1/2-ounce can of condensed cream of chicken soup, one 8-ounce jar of processed cheese and 1 1/2 cups of cooked long grain white rice.
Cook until the cheese is melted, then pour the mixture into a 2-quart shallow baking dish. Place the dish into an oven that has been preheated to 350 F. Bake the casserole for approximately 30 minutes or until it is hot and bubbling. Some home cooks who reviewed this recipe on the Campbell's Kitchen website suggested adding a layer of crescent dough to the top before baking for a fluffy crust. One reviewer said that she adds some chopped cooked chicken in order to make this dish a complete meal.
