This simple broccoli and rice casserole is a great recipe to have on hand when you need a delicious dish. It makes a nice side for any meal and can serve as an entrée when you want a lighter, vegetarian dinner.

The casserole can be adapted in a variety of ways and become as cheesy as you like. Inside, use either shredded cheddar, Cheez Whiz, or Velveeta. You can also top the casserole with as much cheese as you like and add breadcrumbs, pimentos, or garlic to make it even more interesting.

Glass Bakeware Warning

For premade casseroles or leftovers that are refrigerated in a glass baking dish, do not place directly into a hot oven as the glass can shatter. Instead, put any cold glass bakeware into a cold oven to warm up while it preheats. Or allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.


  • If you don't have Cheez Whiz but want a similarly creamy and flavorful result, you can make a substitute with Velveeta or cheddar cheese. Combine 4 ounces of Velveeta or cheddar cheese, 1/3 cup evaporated milk, 1 tablespoon of butter, a dash of salt, and 1/2 teaspoon of dry mustard. Add a dash of cayenne pepper or Tabasco sauce, if desired. Stir over low heat until the mixture has melted. 
  • To thaw frozen broccoli, place it in a colander under cool running water. If you prefer fresh broccoli, use about 10 to 12 ounces of florets. To cook either, put the broccoli in a saucepan with 1 inch of water or in a steaming basket over 1 inch of water. Steam for about 5 minutes, or until just tender.
  • This casserole can be frozen for later. Wrap the unbaked casserole very well and freeze. Before baking, defrost in the fridge and add a few minutes to the baking time.

Recipe Variations

  • Add a buttered breadcrumb topping to the casserole. Toss 1 cup of fresh soft breadcrumbs with 2 tablespoons of melted butter. Sprinkle the buttered breadcrumbs over the casserole just before it goes into the oven. Grated Parmesan cheese and toasted almonds are other ideal toppings.
  • Add a few tablespoons of drained, chopped pimentos to the broccoli mixture for some extra color and flavor.
  • Rub the cut side of half a garlic clove over the inside of the casserole dish or add 1 finely minced clove of garlic to the butter along with the chopped onion.
  • Make the casserole with half cauliflower and half broccoli.
  • Cooked white rice or brown rice will work for this recipe.
