Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Egg substitute sets the custard that binds the bread and filling together.
Whole grain bread
Soaks up the milk and egg mixture, forming the layered structure of the casserole.
Skim milk
Hydrates the egg custard, giving a soft, moist texture once set.
Cottage cheese
Adds moisture and creaminess to the mushroom filling.
Cheddar or monterey jack cheese
Melts and browns on top, adding savory flavor and color.
Mushrooms
Provide the main savory, earthy flavor and bulk of the filling.

The step that matters

Bake until the mixture is set and the top is browned. Underbaking leaves the egg custard loose and runny in the center, while overbaking makes it dry and rubbery. The custard is done when it no longer jiggles in the middle and the top has colored.
