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

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 recipe is simple absolutely delicious and just perfect the way it’s written

    Very good. Only issue is the egg seeps under the biscuits and inhibits them from browning. Maybe I’ll bake for 10 minutes just with the biscuits next time. I think adding green onion would help too.

    1. Lil'Luna Team says:

      Thanks for the feedback. I’m so glad to hear that you enjoyed the recipe!

    Tried the sausage, cheese biscuit casserole and it was delicious! My 4 kiddos and bf absolutely loved it! Not a bite was left on their plates!

    Excellent breakfast dish for the family as they go off to work. I just added green onions to the top.
    Thank you
    Much appreciated

  6. Mom of 2 says:

    I thought it had too much bread. One pound of biscuits to eight eggs, made it too dense and dry. Flavor was good. I added some cayenne pepper.

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

    A friend made this and it was perfect and delicious. I tweaked the recipe and had a ton of problems, but I still believe in this recipe. I used an 8×8 pan to get a thicker casserole, but it overflowed in my oven and set off the smoke alarm! Oopsie! I dropped the temp to 375° but had to cook it over an hour and tent the top with foil. I made a vegetarian version with sautéed mushrooms, onion, green pepper, and salsa fresca. It just didn’t want to cook through though, and I’m wondering if the milk is necessary? Topped it with avocado, sour cream, and green salsa. I made the mistake of getting honey butter biscuits. My friend says the “flakey” ones are the best. I’ll read the can better next time.

    Delicious

  9. Denise Pia says:

    Holy COW. This was soooooo easy and by far one of the best tasting breakfast casseroles I have made. My husband loved it. Said it was “just perfect!” Next time I want to try adding some caramelize onions or chives!! Again. A must keep recipe forever YUM thumbs up

    I halved the recipe. Turned out fine, beautifully moist actually. But I don’t understand what the biscuits are suppose to do? The sont brown up or actually bake, they just sorta become a doughy layer – anyone else experience this? I think I’d just go more keto friendly and leave that layer out.

    1. Denise Pia says:

      So sorry. My biscuits baked up perfect. And actually some of the egg mixture went under them, so it was a fluffy in between layer for ours

      Too much biscuit for my liking. Next time I will use half as Manu abd split them in half through the middle and save the other 4 biscuits for something else. I added fresh roasted green chilies to mine and used pepper jack cheese and sharp Cheddar cheese , instead of mozzarella because that seemed odd to me. It was good but too much on the biscuits for me.
