This Biscuit Egg Breakfast Casserole recipe is filled with biscuits, cheese, eggs and sausage, and takes only minutes to throw together! It’s a family favorite for weekends and holidays!

We’ve always been huge fans of breakfast foods and often have them for dinner, which means we enjoy them ALL THE TIME. Breakfast casseroles now have become a staple – like our French Toast Casserole and Sausage Egg Casserole.

Breakfast casserole with biscuits

What I like most about breakfast casseroles is they are delicious, usually take minutes to put together, and are easy to change up with different meats (ham, sausage, bacon), veggies and cheeses!

This easy breakfast casserole recipe has been one we’ve made for many brunch occasions, holidays and weekends. It’s loved by the entire family and has become our go-to breakfast bake.

We also love that it is super simple and takes just a few minutes to throw together. If you are like us, and enjoy a great breakfast casserole, then you should definitely give this a try.

Biscuits pressed into the bottom of a baking dish.

How to Make

A lot of breakfast casseroles require you to assemble the casserole and refrigerate it overnight before baking. This sausage and egg casserole, however, doesn’t have to refrigerate at all!

You can throw it together from scratch in 5-10 minutes, pop it straight into the oven, and enjoy it 30 minutes later.

MEAT. If cooking meat, brown in large skillet until no longer pink and drain grease/fat.

ASSEMBLE. Line bottom of greased 9×13 inch baking dish with biscuit dough, firmly pressing to seal. Sprinkle with your choice of meat (we prefer sausage) and shredded cheese. Whisk together eggs, milks, salt, and pepper in a large bowl until blended, then pour the egg mixture over the sausage and cheese.

BAKE. Bake at 425° for 25-30 minutes, or until set. We recommend letting the casserole rest for at least 5 minutes before cutting and serving.

Eggs mixed up in large mixing bowl.


Although these are the standard ingredients, you can change up the flavor by adding:

  • onions
  • spinach
  • mushrooms
  • chopped bell peppers
  • chopped bacon (or even use in place of sausage)

These can be added to the large mixing bowl, when whisking together the eggs. You can also top with green onions, chives or avocado.

Breakfast casserole ingredients layered in baking dish.


Note: Oven temperatures can vary. Make sure to bake the casserole for a little more or less time depending on your oven. You don’t want the casserole to be runny, or to dry out so adjust cooking time as needed.

  • When you think it’s done, stick a knife into the middle and see how soft it is. This will help to make sure it’s cooked to your liking.
  • In addition to sticking a knife into the middle of the casserole to check for doneness, you can also jiggle the pan slightly to see if the center moves too much. When the center is firm, your casserole is done.
  • If your casserole appears to be too runny, it probably needs more time to cook. Place it back in the oven and check for doneness at 5 minute intervals.

Making ahead and storing

MAKE AHEAD. If you’re wanting to make this recipe ahead of time, it’s super easy! 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.

STORE. You can keep leftovers in the refrigerator for 3-4 days. Cooked eggs will only last about 4 days in the refrigerator.

FREEZE. If you happen to have any egg casserole left over you can keep it frozen in the freezer for up to 2 months. Keep it frozen in a freezer-safe container. When you’re ready to eat it, reheat individual servings in the microwave.

You can also freeze unbaked egg casserole up to 2 months and let it thaw in the refrigerator before you’re ready to bake it.

We also enjoy making this recipe for special occasions and holidays. It’s always a hit and is one we’ve made on Christmas morning many times!

    This recipe is sooooo good! I use hot sausage and one tiny addition: after baking, I make country white peppered gravy and pour over all. It’s amazing!

    I’ve been making this for a long time and I can tell you I found that adding sauteed mushrooms to this is the best! I use a whole small box of sliced mushrooms sauteed in butter. I put it over the sausage and you have something like no other. If your family loves mushrooms like my family does you will have something that you will never stop making.

    Caramelized onion,red peppers, ham,mushrooms. Loved this.

  6. Stina says:

    I just made this and it came out upside down. During cooking the egg sunk to the bottom, and the biscuits rose to the top. I wanted the biscuits to be a crust on the bottom. How do I get it to cook right?

  7. Lisa says:

    I made it exactly as recipe stated, except for adding chopped onion. After it was done baking and I served it, I noticed the egg mixture baked on the bottom, the the biscuit layer was in the middle, but not flattened.
    It tasted good, but in the future I would have a gravy on the side, as this was a bit dry.

    1. Jamie Mansfield says:

      I actually pour country white gravy over the top of the whole casserole after it bakes. It’s so yummy
