We LOVE a good breakfast casserole! They’re perfect for holidays (especially Christmas morning), brunch, showers and especially when you have company in town.
Today’s easy breakfast casserole 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!
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 also be made ahead of time (the night before) or easily whipped up right before baking – versatile AND delicious!
Why we think you’ll 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!

Breakfast Casserole Ingredients
- Grands! Biscuits (1, 16.3-ounce can, 8 count): Press into the pan to make a buttery, flaky base that holds the casserole. Or 16 ounces Homemade Biscuit dough (partially cook before adding the toppings to ensure it cooks thoroughly.)
- Jimmy Dean precooked sausage crumbles (1, 8-ounce package) or crumbled cooked sausage (1 cup): Savory protein that adds hearty flavor in every bite. If using regular sausage, cook in a skillet over medium heat cooking the sausage, breaking and flipping, until no longer pink.
- Shredded mozzarella cheese (1 cup): Melts stretchy and creamy for that classic cheese pull.
- Shredded cheddar cheese (1 cup): Brings sharp flavor and helps the top brown golden.
- Large eggs, beaten (8): Set into a fluffy layer that binds the filling so slices hold together.
- Milk, room temperature (1 cup): Loosens the eggs for a tender, custardy texture.
- Salt and pepper to taste: Simple seasoning that brightens and balances the rich ingredients.
- optional veggies – Saute and add spinach, mushrooms, and red bell peppers.
- optional toppings – green onions, bacon bits, sour cream, salsa, or hot sauce
How to Make A BiscuitBreakfast Casserole
PREP. Preheat the oven to 425°F.

BISCUITS. Line the bottom of a greased 9×13-inch baking dish or pan with 1 can of refrigerated biscuit dough, firmly pressing to seal and make a bottom crust.

SAUSAGE. Sprinkle with 8 ounces of cooked sausage, 1 cup of shredded mozzarella cheese, and 1 cup of shredded cheddar cheese over the crust.

EGGS. In a large bowl, whisk 8 eggs, 1 cup milk, and salt and pepper to taste until blended. Pour the egg mixture over the sausage and cheese.
BAKE. Bake for 25–30 minutes, or until set and middle does not jiggle. Let this egg bake recipe stand for 5 minutes before cutting into squares. Serve warm.

Kristyn’s Recipe Tips
- Make it any meat. Turkey, chicken sausage, bacon, ham or spicy chorizo all are great for this recipe. You can even add a combo of any of these meats to make it meat lovers.
- Savory and Sweet. For any function, holiday or get together, we love to make this recipe and also make a sweet casserole like our French Toast Casserole, Coffee Cake or Cinnamon Roll Cake. Everyone loves the combo!

The Family *loved* thIs! If you top it with syrup when serving it, its the icing on the cake. i wiLl be making a douBle batch next time.
I’ll have to try! So glad your family loved it! Thank you!
So easy & delicious! This was perfect for when I had family visiting over Christmas – everyone asked for the recipe!
I looked on Pinterest for Christmas breakfast ideas and this recipe came up. It looked simple enough and Made plenty for all the family visitng. It was such a huge hit that several people asked for the recipe and have since made it themselves. I’ve made it at least twice a week since Christmas, it’s that good!
The only thing i changed is that i use both sausage and bacon, because why not? And i use 9 eggs instead of 6, because agAin, why Not? Tip: when re-heating Leftovers, Cut the portion Into a couple sliCes and put a little Pat of butter in between each slice so that it is not dry.
This is a simple but excellent classic breakfast casserole that i will be keeping in my meal rotation.
That sounds great!! I am so glad it was a hit & thank you so much for sharing the recipe!
cOULD YOU DO THIS IN A ROASTER OVEN? THIS SOUNDS AMAZING AND SOMETHING THAT MY CO-WORKERS WOULD LOVE, BUT I NEED SOMETHING THAT CAN BE DONE IN A ROASTER OVEN TO KEEP WARM FOR A COUPLE OF HOURS. THANK YOU FOR YOUR HELP! CAN’T WAIT TO TRY IT FOR MY FAMILY 🙂
I am sure it could, though I have never tried. I am sure it would be a hit!
While I do appreciate the nutritional info, it doesn’t help much unless the number of servings is given. People’s portions can & do vary greatly. Thanks.
