Recipe Instructions

You’re going to love how easy this bubble up breakfast casserole is to make. Simply cook the bacon and sausage and then some layer everything and it’s ready to go! It’s perfect to prep in advance of Christmas morning or any time you’re hosting guests for breakfast!

  1. Cook Bacon: Preheat the oven to 350 degrees Fahrenheit and spray a 3-quart baking dish with cooking spray. Add the bacon to a large skillet and cook over medium-high heat until all the bacon is crisp. Use a slotted spoon to remove the bacon from the pan and then place it onto a plate or bowl lined with paper towels to drain.
  2. Cook Sausage: Add the sausage to the bacon grease in the skillet and cook on medium-high heat until browned and no pink remains. Break it into pieces as it cooks. Use a slotted spoon to remove the sausage from the pan and then place it on the plate or bowl lined with the bacon. Set aside.
  3. Biscuits: Cut each of the biscuits into six pieces and then place them on the bottom of the prepared baking dish.
  4. Assemble: Add the cooked bacon and sausage evenly over the top of the biscuits.
  5. Egg Mixture: In a large bowl, whisk the eggs, half and half, salt, pepper, garlic powder, dried onion flakes, and chives. Pour over the top of the biscuits and meat.
  6. Add Cheese and Bake: Sprinkle the cheese evenly over the top. Bake for 28-30 minutes, until the biscuits are baked through and the eggs are no longer runny. Let the bubble up breakfast casserole sit for 5 minutes before garnishing it with additional chopped chives and serving.

Biscuit Breakfast Casserole Tips and Variations

This bubble up breakfast casserole is so delicious! Here are a few ways you can customize the recipe to make it your own.

  • Biscuit Type: I used a 16 oz. can of Pillsbury Grands biscuits and cut them into 6 pieces. If you use a 12 oz. can of regular-sized biscuits cut them into quarters instead.
  • Add Veggies: You may add peppers, onions, mushrooms, or whatever vegetables you would like to this casserole. Be sure to cook them in a skillet before adding them to the baking dish along with the meat.
  • Change the Meat: You can use a variety of meat in this casserole, but I recommend keeping it around one pound total. Try using diced ham, maple sausage, hot sausage, turkey sausage or chorizo!
  • Cheese Options: You can change up the cheese as desired. Monterey Jack, Pepper Jack, or cheddar cheese would be great choices! 
  • Toppings: Serve the bubble up breakfast casserole with some yummy toppings, like salsa, hot sauce, green onions, avocado, and extra cheese!

Storing Leftover Breakfast Casserole

This dish stores really well and leftovers are great warmed up for quick breakfasts. As an added plus, you can prep it ahead of time and it’s freezer-friendly.

  • In the Refrigerator: Keep leftovers in an airtight container or covered tightly with plastic wrap. Store in the refrigerator for up to 5 days. 
  • Reheating: Reheat in the microwave 30 seconds at a time, until steaming. Or heat in the oven at 350 degrees Fahrenheit for 10-15 minutes. 
  • Prepare Ahead: Prepare everything through the middle of step 6. Instead of pouring the egg mixture over the biscuits, cover both the egg mixture and the baking dish with plastic wrap and keep in the refrigerator for up to 24 hours. Just before baking stir the egg mixture well and pour it over the biscuits and meat and top with the cheese. Bake as directed. 
  • In the Freezer: Freeze bubble up breakfast casserole by making it in a freezer-safe baking dish and covering it well with plastic wrap and then a couple of layers of aluminum foil. Before baking, let the casserole thaw at room temperature for 2-3 hours. Bake at 350 degrees Fahrenheit for 35-40 minutes.
