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!

    Can you use an 8×8 baking dish?

      Yes you can, but you will want to half the ingredient amounts.

    Love this recipe for weekend breakfasts! Itโ€™s a nice change to similar recipes with potatoes in them.

    Looks good

  9. Marianne Vitaliano says:

    This breakfast casserole looks like a great way to start the morning. Easy to assemble, and quick to make, it would be a wonderful, breakfast that will make enough for second helpings! The ingredients are easy to find and you can also change it up a bit. I would love it with chicken sausage and spinach! This is a great breakfast dish to “make and take” too. I will make one with the original ingredients and one with my chicken sausage and spinach (which I will freeze.) Additionally, it is not high in calories. Great recipe…thank you!
