Our Go-to Breakfast Casserole recipe!

We LOVE a good breakfast casserole! This one 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! We make it for brunch, holidays, and weekends (for breakfast OR dinner). 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 be made ahead of time (the night before) or easily whipped up right before baking – versatile AND delicious!

WHY WE 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!

  • 1 cup shredded cheddar cheese – mild or sharp cheddar cheese
  • 8 large eggs, beaten Room temperature eggs incorporate better.

  3. SAUSAGE. Sprinkle with 8 ounces of cooked sausage, 1 cup of shredded mozzarella cheese, and 1 cup of shredded cheddar cheese over the crust.
  4. EGGS. In a medium bowl, whisk 8 eggs, 1 cup milk, and salt and pepper to taste until blended. Pour the egg mixture over the sausage and cheese.
  5. 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.

Notes

Adding vegetables. Add onions, green onions, chopped bell peppers, mushrooms, etc. Saute them first to remove excess moisture and activate the flavors.
Homemade biscuit dough. Partially cook the Homemade Biscuit dough before adding the other toppings to ensure that it will be cooked through by the end.
Make ahead of time. Make casserole through step 4, then cover with aluminum foil and refrigerate overnight. Uncover and bake, adding a few additional minutes to the baking time.
Leftovers. Divide leftovers into an airtight container(s) and keep in the refrigerator for 3-4 days or freezer for up to 2 months.

    I looked on Pinterest for Christmas breakfast ideas and this recipe came up. It looked simple enough and Made plenty for all the family visitng. It was such a huge hit that several people asked for the recipe and have since made it themselves. I’ve made it at least twice a week since Christmas, it’s that good!

    The only thing i changed is that i use both sausage and bacon, because why not? And i use 9 eggs instead of 6, because agAin, why Not? Tip: when re-heating Leftovers, Cut the portion Into a couple sliCes and put a little Pat of butter in between each slice so that it is not dry.

    This is a simple but excellent classic breakfast casserole that i will be keeping in my meal rotation.

    1. Kristyn Merkley says:

    1. Kristyn Merkley says:

      I am sure it could, though I have never tried. I am sure it would be a hit!

  6. Sam says:

    While I do appreciate the nutritional info, it doesn’t help much unless the number of servings is given. People’s portions can & do vary greatly. Thanks.
