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!

    Havenโ€™t made this yet, but I love breakfast casseroles, and this one sounds amazing and easy. Will make this soon.

    I actually made this casserole for breakfast today and itโ€™s delicious! My only quirk is my egg mixture sunk below my biscuit dough? I layered everything according to your directions, and I baked it in a clear, glass baking dish. Do you know what might have went wrong?

    1. Lil'Luna Team says:

      Hmmm… I haven’t had that happen. But maybe the biscuits needed to be pressed together and to the sides a little tighter so there aren’t any cracks or any way for the egg mixture to sneak under there. Hopefully that would help!

  3. Julie says:

    Can I make the sausage biscuit casserole with biscuits from scratch?

    1. Lil'Luna Team says:

      I always have used the canned dough (mostly for simplicity and ease) but I don’t see why homemade biscuit dough wouldn’t work great too! You’ll have to let us know how it does turn out if you go that route.

    I made this today for my family and it was very easy. However, after being in the oven for close to an hour, the dough was not cooked through. I baked it per the instructions and I have a brand new stove so Iโ€™m not sure what went wrong.

    1. Lil'Luna Team says:

      I’m not sure! Did you bake in a glass or a metal baking dish? Either should work, but glass might cook faster. So maybe that?

    I made this but with a few tweaks. I browned sausage instead of using crumbles and I used 16 ounces. I also added a little garlic powder and onion powder to the eggs. I thought it might be a little dry so I made some sausage gravy and served it on the side. It was a great addition. If I make again I would probably use fewer biscuits or separate the biscuit layers. It was a lot of bread but may have been the biscuits I used. But overall, it was very tasty!

    1. Lil'Luna Team says:

      Thanks for sharing what you did and for giving the recipe a try!

    Tasty but tgr top was brown but the biscuits were too doughy.

  7. Abbey says:

    Excellent and so easy! We did a mix of bacon and chopped up sausage links. I saw some people didnโ€™t like that the biscuit didnโ€™t brown or that the egg seeped underneathโ€ฆ I actually loved those things about it! The only change I made from the recipe was adding a touch of garlic and onion powder to my egg mixture. Will definitely make again!

    I was SO pleasantly surprised by this casserole. Itโ€™s beyond easy to put together, and it tasted amazing. I made a vegetarian version with no sausage and just bell peppers and onion, and it was still so flavorful. This will be my go-to breakfast casserole for sure.

  9. Christen D. says:

    I found your recipe and have literally made it for a few years now. Itโ€™s a tried and true yummy one that I love bringing to new moms or sick friends. Love it!
