Ingredients

This breakfast casserole with Pillsbury biscuits is so easy! It uses simple, convenient items to keep the prep time minimal. Here’s a look at the highlights but be sure to check the recipe card for the complete list and quantities.

  • Biscuits: I LOVE using Pillsbury Grands biscuits. They cook up so fluffy and light. But of course, you can use a different brand or flavor if you prefer!
  • Sausage: Use a crumbly style breakfast pork sausage such as the Jimmy Dean brand.
  • Cheese: The flavor of sharp cheddar cheese works really well with sausage and biscuits! You can also use Mexican 4 cheese or Monterey jack cheese to add a little kick to this egg casserole.
  • Eggs: This breakfast favorite acts as the glue that holds the casserole together.
  • Milk: Mixed with the eggs to make them creamy, light, and fluffy.
  • Gravy: Use canned sausage gravy to keep things simple!

How To Make Breakfast Casserole

Making this easy breakfast casserole requires just a few minutes of prep! Here’s a look at the main steps.

A collage of the steps for making breakfast casserole from the biscuits, adding the sausage, cheese, and egg mixture then finally the gravy and more cheese.
  1. Add the biscuits. Cut the biscuits into pieces and place them over the bottom of the greased baking dish.
  2. Sausage. Scatter the cooked sausage over the biscuit layer.
  3. Make it cheesy. Top the biscuits and sausage with a cup of cheddar cheese.
  4. Add the eggs and milk. Whisk together the egg, milk, salt, and pepper in a bowl and pour the mixture over the cheese layer.
  5. Add the gravy. Pour the gravy over the egg mixture.
  6. Make it cheesy (again!): Add the remaining shredded cheese over the top.
  7. Bake and serve. Bake your breakfast casserole at 350°F for 40 minutes. Serve it up warm and enjoy!

Tips & Variations

  • Drain sausage. Don’t forget to drain the grease before you place the sausage on top of the biscuits.
  • Oven temperatures. Your breakfast casserole might take longer or shorter depending on your oven. You want to make sure the eggs are cooked, just insert a knife into the center and when it comes out clean then your egg casserole is done.
  • Cheese burning? If the cheese is starting to brown too fast, just cover it with foil.
  • Want to try a different breakfast meat? You can also use diced ham, turkey, or crispy bacon pieces.
  • Swap the milk for half and half or heavy cream if you want a richer egg mixture.
  • Add some veggies. If you like to sneak in some veggies you can saute them on their own or with the sausage. Add them to the casserole along with the sausage. Mushrooms, onions, bell peppers, and spinach are all some favorites.
  • Make it spicy! If you like things with some heat you can use a spicy pork sausage or add some crushed red pepper to the sausage as it cooks.

Serving Suggestions

This easy breakfast casserole is perfect to serve for a weekend breakfast when you’ve got time to let it cook! It’s also special enough for holidays, breakfast for guests, or even a celebratory brunch.

Recipe FAQ

Can you make this breakfast casserole ahead of time?

Yes, you can. You can make this up to 24 hours ahead of time. Just cover it with foil and place it in the fridge until you are ready to cook it. If you want to make it further in advance, you can cook it and then freeze it after it’s cooked for up to three months.

Can I use crescent rolls instead of biscuits?

Sure, just press down the crescent rolls into the bottom of the pan. Oh and don’t forget to press the seams together too!

How do I know when breakfast casserole is fully cooked?

Your breakfast is done cooking when the edges are lightly browned and the center is cooked. It may be slightly wobbly in the center but you shouldn’t see uncooked eggs on top.
