Breakfast Biscuit Bubble Up is an easy to make breakfast casserole full of crumbled sausage, cheese, eggs, and biscuit pieces.
Breakfast casseroles are a favorite of mine around the holidays. This casserole can be prepped ahead of time and then it takes 35 to 45 minutes to bake.
What Is A Bubble Up Casserole?
A bubble up casserole is made with refrigerated biscuits that have been cut into pieces. The biscuit pieces get mixed with the rest of the casserole ingredients. As they bake, they puff up and bubble up around the other ingredients.
This recipe is easy to customize. Leave out the onion or the bell pepper if you don’t like one of them. Mushrooms can be used instead. Diced ham or crumbled bacon can be used instead of sausage. A combination of mozzarella cheese and Parmesan cheese can be used instead or Colby Jack cheese or cheddar cheese.
Leftovers will keep in an airtight container in the refrigerator for 3 to 4 days and can be reheated in the microwave or toaster oven.
Is This Dish Spicy?
As is, this dish is not spicy. To make it spicy, use “Hot” breakfast sausage or add 1/2 teaspoon of crushed red pepper flakes.
To make sure the casserole is fully cooked, use a knife or a fork to check the center and make sure the eggs are set. If the top starts getting too brown before it is set, cover it loosely with aluminum foil.
The casserole can be assembled the night before and refrigerated. It will take slightly longer to bake. Or you can cook the sausage, onion, and peppers the day before and refrigerate them to shorten your prep time.

1 thought on “Breakfast Biscuit Bubble Up”
I make a sausage gravy when I brown the sausage, then pour it over the casserole before baking. It’s a recipe called sausage, egg, and biscuit gravy casserole. It’s so good. I sometimes buy the package mix for “country gravy” and use that instead of making my own gravy. YUM
