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.

    never been big on breakfast casseroles. this is a keeper! after reading reviews I decided to decrease the temp to 375, especially since I was using glass, and bake 20 min. it HADN’T browned yet so I put it in for another 5 min. then it only browned on one side, so I increased the temp to 425, rotated DISH 180, and put in 1 minute. yum!

    1. Kristyn Merkley says:

      Well, thank you for trying this one! Glad you liked it 🙂

  3. Salena Ybarra says:

    I would like to make this for 100 people and have 18x12x3 lasagna roasters, can you please tell me how much more will i have to alter the recipe. Also how many people will 1-18x12x3 pan serve?

    thank you for your time,

    1. Kristyn Merkley says:

      Well, depending on how big you cut the squares, you could get 12 bigger & 16 smaller squares, so if you stuck to 12 bigger ones..that is x the recipe by 8. If you did smaller sizes, you would need to times the recipe by 6. I haven’t used that size of pan before, but maybe 16 nice size pieces? I’m not really sure, but it would depend on how big/small you cut them. Hope that all helps! Good luck!

    I made the 8×8 version as written, except I used pepper jack cheese instead of mozzarella. It turned out great! I think green peppers and onion would be a good addition, and I wonder about topping it with some kind of sauce. Has anyone tried this?

    1. Kristyn Merkley says:

      I haven’t tried with a sauce, but the peppers & onion are great. Glad you liked it!

  5. Mikayla says:

    I was wondering how to get my eggs to not run under my BISCUITS. Any advice?

    1. Kristyn Merkley says:

      Since, it’s liquid..it will run under, but it all cooks together & makes it turn out the way it does 🙂

    I made this last night for the first time and the only change made was I used heavy whipping cream + water in place of the milk. The cheddar used was garlic & herb-flavored and the Jimmy Dean crumbles used were a combo of bacon and sausage. Tasted great! Might would add one more egg in future preparations, but loved it as is. 🙂

    1. Byenia says:

      Oh! AND i DID REDUCE THE HEAT TO 400 DEGREES f (AFTER READING OTHERS’ COMMENTS), THEN ADDED MAYBE 5 MINUTES TO THE COOK TIME (COVERING WITH FOIL THE LAST FEW MINUTES TO ENSURE IT COOKED THROUGH IN THE MIDDLE).

    2. Kristyn Merkley says:

      Thank you for sharing what you did!! Sounds great!
