I wouldn't think so. Below is a recipe for a really basic breakfast
casserole. They are more properly called "STRATA" Look under strata
and you will find a plethora of recipes.
Basic Breakfast Casserole
3 slices
3 slices bread, torn into small pieces
1 lb. sausage, browned
4-8 oz. shredded cheddar (amt. depends on how well you like
cheese
6 eggs
2 c milk
1/4 t. dry mustard
1 t salt
Arrange bread evenly in 9x13 pan. Top with sausage, then cheese. In
medium bowl, beat eggs, then add remaining ingredients and mix well.
Pour over ingredients in pan. Push the cheese below the milk so it
won't burn. Cover and refrigerate. In the morning, bake at 350 for
35-45 minutes (until set, but not over brown). Serve warm.
From there I add mushrooms and broccoli or chopped spinach. Or green
chilies. It is a dinner at my house.
Or you can make them sweet by using some sort of sweet stale bread
(raisin bread etc) Add fruit as you like. Probably sweeten the
milk/eggs. I've never made one but that is the basic. There are
dozens of recipes on the 'Net
NOTE: I bake until the center of the casserole domes a bit. I've
found that is a decent test for doneness.
