For a spicier kick, use hot sausage or add a pinch of cayenne pepper to the egg mixture. Feel free to substitute other cheeses, such as cheddar, Colby Jack, or pepper jack, based on your preference. If you don't have fresh mushrooms, 4 ounces of canned mushrooms, drained, can be used. To make this casserole vegetarian, omit the sausage and add more vegetables, such as bell peppers, spinach, or zucchini. The casserole can be assembled and refrigerated for up to 24 hours before baking. Store leftover casserole in the refrigerator for up to 3 days.

Dec 7, 2023I found it a little bland, so I added some garlic powder and onion powder. Much better!

Oct 18, 2023I substituted pepper jack cheese for Monterey Jack, and it added a nice little kick. Will definitely make again!

Aug 12, 2023This recipe is a lifesaver for holiday brunches! I prepped it the night before, and everyone raved about it.
