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.

  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 love sausage, so I couldn’t wait to try this!! It was so easy!! I can’t wait to make it for extended family! They will love it. It was cheesy & you could also add more meat or cheese to make it to your liking.

    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

      2. Kristyn Merkley says:

        Thank you so much for giving it a try 🙂
