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.

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.

    Looks so yummy! Do you think I could use pilsbury croissants instead?

    1. Lil'Luna Team says:

      I haven’t tried it using them, but I imagine you could. You’ll have to let us know how they turn out if you end up swapping for the croissants.

    My kids regularly ask for this casserole and i change nothing. I have run out of the mozzarella but i’ve used just cheddar and it’s still just as good. i have over baked it twice and it still tasted delicious no one complained! it has replaced my other breakfast casserole recipes all i do is substitute crescent rolls at times. Excellent recipe thank you.

    1. Lil'Luna Team says:

      Oh you’re welcome!! I’m so glad to hear this has become a new family favorite!

    I made this tonight. The only change I made was cutting up each biscuit into 9 pieces and scattered them on the bottom. It made it more a bubble up that way. I also used cream instead of milk that I needed to use. This was super good! One of my favorite breakfast casseroles I’ve tried for sure!

    1. Lil'Luna Team says:

      Yay!! I’m so glad to hear you loved the casserole. Thanks for sharing what you did too.

  4. kenneth barnett says:

    How do you keep biscuits from over cooking on bottom?

    1. Lil'Luna Team says:

      I’d suggest not cooking it on the bottom rack of the oven. That should help with the bottom overcooking.

  5. sallie rae delucantonio says:

    made did not like dough to egg ratio

    1. Lil'Luna Team says:

      Thanks for the feedback and for giving the recipe a try!

  6. Kristen says:

    Has anyone tried to make this ahead and then bake the next morning? Trying this recipe this weekend for the first time. Thanks in advance!

    1. Lil'Luna Team says:

      You definitely can do that! Instead of throwing it in the oven to bake, cover it with foil and refrigerate it until you’re ready to make it in the morning. Hope the casserole turned out well for you last weekend!

    I made this today and its delicious!! I ran into the biscuits floating to the top so the egg was underneath and sausage, cheese, and biscuits were on top. It still tastes amazing though!

    1. Lil'Luna Team says:

      Thanks for sharing. So so happy to hear you enjoyed the casserole!!

    How do I divide this?

    1. LilLunaTeam says:

      If you would like to divide this and make a smaller version here are the ingredients amounts:

      For a smaller version (8×8 pan) use and do the following:

      1 small package 10 biscuits
      almost whole package of Jimmy Dean pre-cooked sausage
      5 eggs
      2/3 cup milk
      3/4 cup mozzarella cheese
      3/4 cup cheddar cheese
      salt & pepper

      *Bake for 20-25 minutes

      Hope this helps!
