Sausage & Crouton Breakfast Casserole - seriously the BEST! SO easy and tastes great! Can make in advance and bake the next morning. Sausage, croutons, cheddar cheese, eggs, milk, heavy cream, onion, and dry mustard. Great for potlucks, brunch, baby showers, early morning tailgates, overnight guests, breakfast, lunch, or dinner. #sausage #breakfast #casserole #freezermeal #breakfastcasserole
