Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place 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.



Tips

  • 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 cheese 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 until thawed. 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. Before baking, wrap 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 great 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.
