We LOVE a good breakfast casserole! They’re perfect for holidays (especially Christmas morning), brunch, showers and especially when you have company in town.

Today’s easy breakfast casserole is filling, takes minutes to put together, and is packed with flavor – biscuits, eggs, and sausage, there’s something for everyone! It’s our go-to breakfast bake!

One reason we love it is because the ingredients are SIMPLE!! There are only a handful, and it’s prepped in 5 minutes – just layer and bake!

It can also be made ahead of time (the night before) or easily whipped up right before baking – versatile AND delicious!

Why we think you’ll love it:

  • Refrigerate overnight or bake it immediately. Either way, this breakfast casserole is quick and easy!
  • Ready in no time! Throw it together from scratch in 5-10 minutes, pop it straight into the oven, and enjoy it 30 minutes later.
  • So filling. Biscuits, eggs, and sausage – it’s hearty and packed with flavor!
Breakfast casserole ingredients on counter.
  • Grands! Biscuits (1, 16.3-ounce can, 8 count): Press into the pan to make a buttery, flaky base that holds the casserole. Or 16 ounces Homemade Biscuit dough (partially cook before adding the toppings to ensure it cooks thoroughly.)
  • Jimmy Dean precooked sausage crumbles (1, 8-ounce package) or crumbled cooked sausage (1 cup): Savory protein that adds hearty flavor in every bite. If using regular sausage, cook in a skillet over medium heat cooking the sausage, breaking and flipping, until no longer pink.
  • Shredded mozzarella cheese (1 cup): Melts stretchy and creamy for that classic cheese pull.
  • Shredded cheddar cheese (1 cup): Brings sharp flavor and helps the top brown golden.
  • Large eggs, beaten (8): Set into a fluffy layer that binds the filling so slices hold together.
  • Milk, room temperature (1 cup): Loosens the eggs for a tender, custardy texture.
  • Salt and pepper to taste: Simple seasoning that brightens and balances the rich ingredients.
  • optional veggies Saute and add spinach, mushrooms, and red bell peppers.
  • optional toppings – green onions, bacon bits, sour cream, salsa, or hot sauce

PREP. Preheat the oven to 425°F.

Biscuits pressed into the bottom of a baking dish.

BISCUITS. Line the bottom of a greased 9×13-inch baking dish or pan with 1 can of refrigerated biscuit dough, firmly pressing to seal and make a bottom crust.

Sausage and cheese poured over biscuits for breakfast casserole.

SAUSAGE. Sprinkle with 8 ounces of cooked sausage, 1 cup of shredded mozzarella cheese, and 1 cup of shredded cheddar cheese over the crust.

Cheese and sausage layered in baking dish.

EGGS. In a large bowl, whisk 8 eggs, 1 cup milk, and salt and pepper to taste until blended. Pour the egg mixture over the sausage and cheese.

BAKE. Bake for 25–30 minutes, or until set and middle does not jiggle. Let this egg bake recipe stand for 5 minutes before cutting into squares. Serve warm.

  • Make it any meat. Turkey, chicken sausage, bacon, ham or spicy chorizo all are great for this recipe. You can even add a combo of any of these meats to make it meat lovers.
  • Savory and Sweet. For any function, holiday or get together, we love to make this recipe and also make a sweet casserole like our French Toast Casserole, Coffee Cake or Cinnamon Roll Cake. Everyone loves the combo!

    This was a quick and easy recipe. I read through the comments before making it and saw that some people had trouble with over/undercooking it. I set my timer for 20 minutes and just kept an eye on it. Mine cooked in about 28 minutes.
    I also made mine 1/2 sausage and 1/2 bacon. The combination was delicious!

        Mine was all gooey inside with egg uncooked in the middle. It was easy to prepare. All the sides was nice brown but to prevent burn on the bottom I may have to lower the temp

        Thank you so much for giving it a try 🙂
