Recipe Notes

Cooking for a Smaller Family? You can cut the ingredients in half and prepare the casserole in an 8-inch square baking dish. Alternatively, you can prepare the full recipe, but bake the ingredients in two separate 8-inch square casseroles. Eat one casserole now and save the other baked casserole in the freezer for later!

Have leftovers? The cooked casserole freezes really well!
