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!

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.

    I have been making this recipe for a while now. I’ve used bacon bits, chorizo, breakfast sausage, different veggies etc. It is so versatile and always a hit!

  2. Sarah-Jane Carter says:

    Can you make this ahead and freeze?

    1. Lil'Luna Team says:

      Yes you can! Freezing/make-ahead instructions are in the post. 🙂

    We made this recipe today and it was a huge hit! I used 9×9 pan and 8 regular canned biscuits. Pressed against bottom of pan and about 1/2 “ up sides of pan. Four hashbrown patties and 5 eggs. Combination of crumbled sausage and Conecuh sausage links diced. Sprinkle of salt, pepper, garlic powder and onion powder. With the shredded cheese I added some French fried onions. Cooked 425 for 30 minutes and everything cooked to perfection! Thank you for sharing your recipe!

    This recipe was a big hit for the family gathering we had a while back. Everyone loved it. I will have to make it for my Easter breakfast. Thank You for sharing.

  5. Lena says:

    Same question as one of the other comments what doing wrong if biscuits are still doughy

    1. Lil'Luna Team says:

      Oven temperatures can vary. So it could just be it needs a little more bake time depending on your oven.

      This is so delicious! I added sautéed onions and asparagus to mine. I also used about half the amount of cheese but it was still so good! Highly recommend.

      1. Lil'Luna Team says:

        Sounds yummy!! Thanks for giving the recipe a try!

    This was amazing. I used gv biscuits and sausage patties, I crumbled them up after baking them with crispy edges. I used 8 eggs instead. My whole family enjoyed it. I am doing a taco doop of this dish tonight using tortillas, hamburger meat, taco seasoning and added green chilies also. Fingers crossed its as great as last night’s dinner. Thank you for the recipe.

    1. Lil'Luna Team says:

      You’re welcome! I’m so glad you enjoyed the casserole. The taco version sounds delicious and fun!! You’ll have to let us know how it turns out!

    Everyone LOVED it!!!! I used crescent rounds roll dough. 1 can fit my 8″x8″ pan perfectly. Next time will add some onion and maybe mushrooms. So simple!

    1. Lil'Luna Team says:

      I’m so glad to hear that!! Thanks for giving the recipe a try!

    This is a great breakfast casserole – however I would not sub for homemade biscuits. I have made this 4 times, twice with canned biscuits per the recipe, once with Bisquik biscuit dough and once with my scratch biscuit recipe. Both times I made it with canned dough, the casserole was awesome. When I made it with scratch biscuits and Bisquik dough, the biscuits were dry, dense and overall just not that great. This is one time I will say to save yourself some time and use canned biscuits because it was WAY better the two times I made it strictly by the recipe. I just wanted to share in case anyone else was thinking of substituting the canned biscuits. Great recipe – thanks for sharing!

    1. Lil'Luna Team says:

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

      1. Linda says:

        Colleen, I did exactly the same thing. Today my husband is at the store buying Grands because it just turns out better than with homemade biscuits. I am afraid that Grands must have some kind of ultra-processed magical additives, but this is for a company breakfast and I’m doing it against my better judgement because I want it to taste better.

  9. Kathryn Madden says:

    I made these this morning! They were yummy but I had a quick question. My biscuits were not fully cooked. Some areas were still doughy. Do you know what I did wrong?

    1. Vandelay says:

      Same thing happened to me, Kathryn. When I took it out lf the oven, it was beautiful and looked done. I did the jiggle test too and it was perfect. However, after cutting into it, my dough was still doughy. I recommend placing your biscuits on counter at least 15 minutes prior to assembling your casserole. This will take the chill off of them. My guess is that the biscuits were still cold from the refrigerator and were not able to cook in the alloted time. I hope this helps!
