This Cottage Cheese Egg Bake is a high-protein breakfast casserole made with fluffy eggs, cheddar cheese, cottage cheese, and breakfast sausage. With simple ingredients and easy prep, it’s a crowd-pleasing, make-ahead meal perfect for busy mornings.
Casserole Dish Size: A 9x13” casserole dish creates a thinner casserole, while a 9x9” or 7x11” baking dish will yield a thicker result. Adjust baking time as needed.
Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days. Let the casserole cool completely before storing to prevent condensation.
Freeze: For best results, freeze before baking. Assemble the casserole, cover tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking as directed.
Reheat: For the best texture, warm casserole in a 350°F oven, covered loosely with aluminum foil to prevent drying out. Remove the foil during the last 5-10 minutes to help the top crisp up slightly.
Make-Ahead: Assemble the casserole up to 24 hours in advance, cover with plastic wrap, and refrigerate. Bake straight from the fridge, adding a few extra minutes to the baking time if needed.
