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 mozzarella cheese – or Pepper Jack cheese or Colby Jack cheese
  • 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.

    This was fantastic! Only changes: 375 oven, and I cooked a pound of pork sausage before adding it (I couldn’t find the pre-cooked crumbles). Will absolutely be making again!

      **I also made the 8×8 version. Perfection!**

    2. Kristyn Merkley says:

      That works well, too! I’m glad you liked it 🙂 Thank you so much for letting me know!

  3. Mary says:

    I made this tonight and cooked it on 375
    By accident. Still came out great. The biscuits could probably have been done a little more if i used the right temp but they aren’t undercooked and I figure I will just reheat in the oven anyway. My question, do you think once baked this would freeze well? It made waay more than I was expecting. Thanks! ????

    1. Lil' Luna says:

      I think it should be ok 🙂 I personally haven’t tried freezing it, but I don’t see why it couldn’t.

    Made this last night..Thank you for a quick and easy and delish meal. Even tasted great for my lunch today at work 🙂

    1. Lil' Luna says:

      Yay!! Thank you so much!! I am so glad you liked it!

  5. Joann says:

    This looks delicious and can’t wait to try it. I do have a question? How many does serve. And i was reading some of the comments, and some were saying it bubbled over. So I was wondering if after you flattened and sealed the biscuits if you poked them with a fork if that would keep it from bubbling over. Thanks so much for the wonderful recipes and keep them coming, Please. Have a wonderful day and God Bless.

    1. Lil' Luna says:

      If could feed 12 with a good size square or more, if you cut them smaller 🙂 You could poke it. I never had that problem, but it could work 🙂 Hope that helps and let me know what you think 🙂 Thank you!

    Overbaked a little due to comments, but made country milk gravy and it was FABULOUS!

    1. Lil' Luna says:

      Yay!! So, glad 🙂 Thank you!

  7. Patty Brown says:

    Do you press the biscuits flat into the pan or just set them in together?

    1. Lil' Luna says:

      You do press them in to seal. Hope you like them!! Thanks!

    This was a big hit for my husband and I. We made it together for date night. We did the 9×13 recipe. We decided to cook our own sausage though and it was still super yummy. What had me concerned was it did expand a ton in the oven but once I took it out after it was done cooking (about 30mins) I stabbed it with a fork and it went down eventually. I also like to keep an eye on whatever I cook because I have a tendency to burn things so that is why I was able to make sure nothing burnt and nothing got too big. After we put the leftovers in a bag and put it in the fridge. It was just as good for the next two days, even after being reheated!

    1. Lil' Luna says:

      What a fun date!!! Thanks so much for sharing and for letting me know!! So glad it was a hit!
