For a richer flavor, use whole milk or half-and-half in the egg mixture and Hollandaise sauce. Add a splash of hot sauce or a pinch of cayenne pepper to the egg mixture for a little kick. Feel free to substitute different types of cheese, such as Gruyere or Swiss, for a more complex flavor profile. If the top of the casserole starts to brown too quickly, cover it loosely with aluminum foil during the last few minutes of baking. Leftovers can be stored in the refrigerator for up to 3 days. Reheat individual portions in the microwave or oven.
