Easy Sausage Biscuit Casserole

Simple and filling breakfast dishes like my overnight breakfast casserole are always a huge hit with my family and this breakfast casserole with biscuits is no exception. It’s so versatile we have even made it for dinner!

While breakfast classics like biscuits and gravy and buttermilk pancakes are favorites, I love that I can prep this the night before and then just throw it in the oven in the morning!

Not only is this breakfast casserole easy to throw together, it’s great for a holiday brunch and makes enough to feed a crowd, too! Serve it with some juice and a fresh fruit platter and breakfast is ready.

  • Easy to make. With less than 10 ingredients and only 15 minutes prep time, this breakfast casserole is simple to throw together.
  • Feeds a crowd: Perfect for holiday guests, a weekend brunch, showers, or potlucks.

Recipe Ingredients

If your family loves biscuits, they will love this easy breakfast casserole that is made with canned biscuits!

  • Canned biscuits: I used a can of refrigerated Pillsbury Grands that contains 8 biscuits.
  • Breakfast sausage: While sausage, ham, or bacon could be used my preference is sausage.
  • Eggs: You will need 8 large eggs. I don’t recommend replacing them with egg whites as it will change the texture.
  • Milk: I like 2% for the best creamy consistency.
  • Cheese: I love the combination of both cheddar cheese and monterey jack cheese, but you could use all cheddar or even some mozzarella cheese, too.

Variations

This biscuit egg casserole is really forgiving if you happen to need a substitute or want to add some variety with some add-ins!

  • Try cubed leftover ham or bacon crumbles either in place of the sausage or in combination with it!
  • Add in sauteed mushrooms, chopped green peppers, red peppers, diced onions, or green onions.
  • Add a few dashes of hot sauce and red pepper flakes in with the egg mixture for a little heat.
  • Use other cheeses such as mozzarella or Gruyere.
  • Use crescent dough like I do in my Crescent Roll Breakfast Casserole.

  • Unroll biscuit dough. In a 9×13-inch baking dish coated with cooking spray, unroll your biscuit dough, place it in the bottom of the dish, and press the seams together to seal. Bake for 5 minutes.
  • Cook sausage: In a large skillet, cook your sausage crumbling it with a spatula over medium heat.
  • Whisk eggs: In a large bowl, whisk eggs first then add in milk, salt, garlic powder and pepper.
  • Assemble casserole: Assemble casserole by sprinkling the sausage over the biscuits first, followed by the shredded cheese and then the egg mixture. Sprinkle with more cheese if you like!
  • Bake: Bake 30 minutes at 400 degrees F or until a toothpick inserted into the center comes out clean. 
  • Rest: This casserole is best when you let it sit for 5 minutes, then just slice and serve. Enjoy!

Expert Tips

  • Oven temperatures vary: Your biscuit breakfast casserole may take a few minutes more or less. Cook just until a knife inserted in the middle comes out clean to prevent too runny of eggs or worse dry eggs.
  • Drain sausage: To remove excess grease before placing it on top of biscuits.
  • Don’t skip whisking your eggs: For your dish to cook properly, whisk eggs prior to adding them to the casserole.
  • Browning on top: If you find that your biscuit breakfast casserole is browning too quickly, cover it with foil.
  • Make ahead: Cover your unbaked casserole and refrigerate up to 12 hours. When ready to bake, uncover and bake as directed. It may require a few minutes of extra cooking time since the mixture will be cold.
