You know I'm a breakfast casserole girl, I can't help it! From my savory croissant breakfast casserole to my sweeter pumpkin french toast casserole, I'm always dreaming up new ways to make my mornings more delicious! This biscuit breakfast casserole has quickly become one of my favorite recipes. Not only is it such an easy recipe to whip up, but it's hearty, cozy, and guaranteed to please a crowd.

Packed with all my favorite ingredients- fluffy eggs, savory breakfast sausage, and plenty of melty cheese- this cheesy biscuit casserole is the ultimate comfort food. I top it with golden, buttery biscuits (store-bought, obvi) for the perfect finishing touch. It's everything you love about a big breakfast, baked into one warm and satisfying dish.

I also love that using store-bought canned biscuits makes the recipe come together in a flash. I really love when I can make a dish that has a ready-made component to make life easier, like these puff pastry breakfast cups.

If you want even more hearty breakfast dishes, you have to try my Hawaiian roll breakfast sliders, potato breakfast burritos, and these bacon and cheese turnovers.

ingredients you will need

Ingredients for a breakfast recipe: shredded cheese, turkey sausage, eggs, cream, salt, pepper, and biscuits.

Eggs: you'll need 12 whole eggs for this breakfast casserole! The eggs are not only going to make this casserole soft and fluffy, but they provide structure to the casserole and hold everything together.
Milk: I'm using whole milk, but you can swap it out for dairy-free milk.
Cheese: I'm using cheddar cheese, but you can use whatever cheese you like. Pepper jack, mozzarella, or swiss would also be delicious in this!
Breakfast Sausage: adding some breakfast sausage is going to bulk up this breakfast casserole and add some protein. I used turkey sausage, but regular breakfast sausage works perfectly as well.
Biscuits: I'm using a regular can of biscuits for this recipe. It will make the top of the breakfast casserole super flaky and buttery.

How to make

Making this casserole could not be easier. The most time consuming part of this is cooking the sausage before-hand! Oh and waiting patiently for it to finish baking in the oven.

Whisk eggs, milk, salt, and pepper into a bowl. Add the cheese and cooked sausage.
Pour into a greased baking dish. Top the casserole with store-bought biscuits.
Bake until cooked through and golden brown on top!

After letting the casserole cool for about 10 minutes, slice it up and dig in! I like to top mine with some freshly chopped scallions.

What else can I add to this casserole?

swap the meat- bacon would be great in this recipe! I used turkey sausage, but regular breakfast pork sausage works, or even a spicy sausage!
try veggies- adding veggies would bulk up the flavor big time to this casserole. Cooked spinach, broccoli, onions, mushrooms, tomatoes, or bell peppers would be great in this.
add gravy- biscuits and gravy is a staple breakfast meal, so why not add it on top of this! Use store-bought for convenience or make your own from scratch!
make it southwest-style- add black beans, green chiles, and a sprinkle of taco seasoning. Top with avocado, salsa, or sour cream right before serving.

Storage and Reheating

Let the casserole cool to room temperature, then store it in an airtight container in the fridge for up to 5 days. Reheat individual servings in the microwave or oven. To freeze, place slices in an airtight container in the freezer for up to 3 months. Let thaw overnight in the fridge before reheating.

Can I make this ahead of time?

Yes! You can make this casserole the day before by following steps up until adding the biscuits. Before you add them, stop and cover the baking dish with foil, and place it in the fridge. Whenever you're ready to bake it, add the biscuits.
