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.

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.

      Made this for my MIL’s birthday brunch and it was a hit! We didn’t have precooked sausage available which was ok because it only took a little under 10 minutes to cook. I had to make a few other modifications since we were at our second home and didn’t have the regular pans I am accustomed to using when cooking. The baking pan was larger than 9X13 so I used enough biscuits (in a bag) to fill the bottom of the pan, a carton of eggs, additional milk and cheese since I was making a larger batch, and I threw in some seasoning for the eggs and bell peppers. Everyone raved about how delicious it was and many went back for seconds. I could easily make a vegetarian version with veggie crumbles and look forward to doing that in the future. Thanks for such a simple, delicious recipe!

      1. Lil'Luna Team says:

        Oh you’re so welcome! I’m glad that the casserole was a hit for your family. And you made-do with what you had too… I love it! A veggie version would be really tasty too. Thanks for sharing!

    So yummy! I used turkey sausage. I added mushrooms and bell peppers to it. I used Monterey Jack and cheddar cheese.

    1. Lil'Luna Team says:

      Mmm sounds like wonderful additions!! So glad you enjoyed the casserole and adapted it to what you like!

    I’ve used this with crescent rolls and biscuits, with great results. I’ve also used cooked chopped link sausage, bacon, and ham — whatever I’ve had on hand. Same with the cheese. I usually make a half recipe for an 8×8 pan and cook at 400 for about 30 minutes. Works great. As long as I stick with the correct milk and egg measurements, it all works. I have it bookmarked, and have probably made it 10 or 15 times. Thanks for a great recipe!

    1. Lil'Luna Team says:

      Thanks for sharing!! I’m so happy to hear this is one of your favorite/go-to recipes too.

    I have to tell you I made your breakfast casserole for dinner last night… it’s similar to one that I have made for 15+ years (it uses crescent rolls and regular sausage)… but I have to admit that I like yours better!!! 😜😜😜.

    Not only was it super nice not having to cook the sausage (because that just takes forever) but it was much more dense because of the biscuit and it rose much more which made it more filling…

    Definitely give it a solid Two thumbs up from me and thumbs up all around from my breakfast for dinner loving happy family!

    Thanks for a great recipe.

    1. LilLunaTeam says:

      I’m so happy that you and your family liked it so much! Breakfast for dinner is one of my favorite meals and I’m glad this casserole turned out so well for you. Thanks for sharing! 🙂

        This was SO delicious! I had company and made one pan of this as written, and also made a mostly dairy-free version (I am sure the biscuits have some dairy in them, but I used oat milk and omitted the cheese). This is definitely a keeper! I just made another mostly dairy-free pan to take to work for breakfast this week and I cleaned out my produce bins in the refrigerator, adding onions, poblano peppers, mushrooms, and spinach. I can’t wait to eat this at my desk in a couple hours. It definitely helps me make it through my Monday mornings! Thank you for the recipe!

      2. LilLunaTeam says:

        You are so welcome! I love all of the additions you used in the casserole. I hope it turned out tasty for you! Thanks for sharing!

    I made the smaller version of this using a quiche dish. I could only find a 10 piece roll of small biscuits which was plenty. It was quick and easy to make and, I thought, delicious. Thanks for the recipe.

      Glad to share 🙂 Glad you liked it! Thank you!

        Made it (the 8×8 size) and it was gr8 !! Except I didn’t use pre-cooked sausage, I fried up my own.

      2. Lil'Luna Team says:

        Ooh I bet the fresh cooked sausage tasted delicious in the casserole! Thanks for sharing!
