Ingredient Notes

See recipe card for exact amounts.

• Sausage: Precooked breakfast sausage keeps this casserole easy to assemble. You’ll find it in the refrigerated section of the grocery store.
• Potatoes: I use Simply Potatoes diced potatoes because they’re cooked and ready to use. Any refrigerated, precooked diced potatoes will work.
• Biscuits: I like Pillsbury Grands biscuits for this recipe because they give the casserole a great texture. Homestyle or flaky layers both work.
• Cheese: Pre-shredded cheese keeps this recipe as easy as possible. 
• Milk: Whole or low-fat milk will work great. 

How to Make Sausage Egg Biscuit Breakfast Casserole

1. Spray a 9X13-inch casserole dish with non-stick cooking spray. 
2. Cut each biscuit into eights. Place the biscuit pieces into the bottom of the prepared baking dish. Spread the sausage and potatoes over the biscuits. 
3. In a large bowl whisk the eggs, milk, salt and pepper until combined. Pour egg mixture into the casserole dish and top with shredded cheese. 
4. Bake in a 350° oven for 40-45 minutes or until the edges begin to brown and the middle is set. 
5. Let stand about 10 minutes before cutting and serving.

To Make the Night Before

Prepare as directed above using only 1 ½ cups of the cheese, cover and put into the refrigerator. 

When ready to bake it preheat the oven to 350°. Top with the remaining ½ cup cheese and bake 48-52 minutes or until the edges begin to brown and the center is set. 

Let stand about 10 minutes before serving.

Tips for the Best Sausage Egg Biscuit Breakfast Casserole

• I find using a shallow glass baking dish works best. I have made this in a taller ceramic baking dish and it browned too much on the outside. 
• The casserole is done when the edges are lightly browned and the center is set. Insert a knife into the center; it may have clear sausage grease on it, but there should be no wet or uncooked egg mixture.

Variations

This sausage egg biscuit breakfast casserole is easy to customize with your favorite breakfast ingredients.

• Swap the sausage for cooked bacon, ham, turkey sausage, or a combination of meats.
• Use your favorite shredded cheese. Cheddar, Colby Jack, Monterey Jack, or a cheddar blend all work well.
• Use thawed hash browns if you cannot find refrigerated diced potatoes.
• Add ½ cup diced bell pepper, ½ to 1 cup diced onion, or both.
• Serve with sour cream, salsa, and green onions for a Mexican-inspired version.
• For extra comfort-food flavor, serve it with bacon gravy or white gravy .

Storage and Reheating

• Store leftover baked casserole in an airtight container in the refrigerator for up to 3–4 days.
• Reheat individual servings in the microwave until hot throughout.
• To freeze, wrap individual portions of the baked casserole and place them in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator, then reheat until hot throughout.
