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!

    Really loved this recipe! Made it vegetarian using Morningstar Farms Chorizo. Also sprinkled a little extra cheese on top. Will definitely make it again! The recipe made a big pan so I can eat it for lunch this week! (Iโ€™m single). Had planned on making it for a brunch but didnโ€™t go. Iโ€™m sure with sausage carnivores would love it too.

    Got up this New Years morning and had no idea what to cook! Found this recipe, was out of sausage, so I made it with fresh crumbled bacon and diced deli ham (sautรฉed in butter first). Everyone loved it, hubby looked at me crazy at first because we never do casseroles. After his first bite, he said, you mean youโ€™ve been making me bacon and egg biscuit sandwiches instead of this? Winner in our book!

    Changes I made- subbed crumbled fresh bacon and diced deli ham for sausage. Next time I think Iโ€™ll do all 3 meats.

    Topping- I topped mine with homemade country gravy along with the kids.
    Hubby topped his with shredded hash browns & Tabasco.

    Excellent recipe! I used ham instead and my 4 grandsons cleaned their plates. Will save this recipe!

    Made this today! Excellent and cooked pretty fast. I added onions to half and broccoli and asparagus to the other. Will be making this again. Thank you! ๐Ÿ˜Š

  5. Jean says:

    Flavor was great, but it was a little dry and mostly dough. I will use smaller biscuits next time.

    I just made this with morning star farms plant based chorizo crumbles and it was amazing!

    Huge hit for our Christmas brunch!
    I was surprised how simple but delicious this dish was. We used 2 cups of Colby jack cheese and a pound of jimmy dean maple sausage. It was so good.

    Maybe would have cooked better if the victors had been cut into pieces as well. It took much longer to cook than 30 minutes. I kept having to put it back in the oven. The dough was raw and eggs still runny. I probably had to cook it closer to 50 minutes. Too much guessing in this recipe. Would not make again, Iโ€™d look for another.

  9. Sue says:

    Can I make it night before?

  10. Megan says:

    This unfortunately turned out horrible! My biscuits evidently floated and all the egg ran to the bottom, making it a plain (overcooked since it went to the bottom) egg layer, mushy biscuit layer, then over dried toppings/ mix ins (onion, bell pepper, sausage, mushrooms) because they didnโ€™t have any egg to protect them. Tastes so bad. ๐Ÿ˜‚ I pressed the biscuits together quite well when lining the pan, so Iโ€™m not sure how I could have prevented this. Wasted all my delicious ingredients ๐Ÿ™

      So sorry to hear the casserole didn’t turn out for you. Thanks for the feedback and for giving the recipe a try!
