When a friend on Facebook shared this recipe, I immediately saved it and knew we had to try it. My kids are HUGE fans of any breakfast casserole I make, so I figured this one would also make them happy. I was right.

I see this recipe as one we’ll have for everyday breakfast, a special occasion, or even holidays like Easter or Christmas morning. It’s a hearty breakfast casserole with biscuits and gravy that is delicious, filling, and easy to make!

Make-Ahead Sausage Biscuits and Gravy Casserole

This hearty casserole can be easily prepared and assembled the night before. This will cut your prep time way down if you’re making it for a shower, a brunch, or a holiday morning.

Follow all of the instructions to make it an overnight breakfast casserole, right up until time to put it in the oven, cover it with foil, and stick it in the fridge. If you do this, you’ll need to set it out the next morning for 30-60 minutes to come to room temperature. Then baked as directed.

If you want to bake it straight out of the fridge, you’ll need to bake it an extra 15-20 minutes. Keep a close eye on it and if the top begins to brown before the bake time is up, cover it loosely in foil to finish baking the last few minutes.

Homemade Gravy. This Sausage Gravy Biscuit Casserole includes making easy homemade gravy recipe, but you could use Gravy packets for a shortcut. You can also double the homemade gravy and have it on the side to pour over the cooked casserole.

Cheddar Cheese – You could spice this up by substituting 1 cup cheese with pepper jack cheese or simply replace all of the cheddar with another variety of shredded cheese that you love.

Grands Biscuits – other varieties of refrigerator biscuits would work just as well in this recipe. The goal is to have any kind of fluffy biscuits beneath the sausage gravy.

How to Make Biscuits and Gravy Casserole

1. Preheat oven to 350 °F and spray a 9×13 dish with nonstick spray.
2. Cut biscuit dough into fourths and spread them in the bottom of the pan in a single layer. Set aside.

How to Make Homemade Gravy

If you’ve never made gravy, this Sausage Gravy recipe is really easy and you may find yourself making gravy all the time!

1. In a large cast-iron skillet over medium-high heat, crumble and cook the ground sausage until browned and fully cooked.
2. Dip the browned sausage out with a slotted spoon and spread over the biscuits. Drain most of the grease – leaving 2–4 tablespoons of drippings in the skillet. Note: you can leave the sausage in the gravy and scoop the whole gravy mixture over the top in step 9 if you like.

3. Sprinkle the flour over the hot drippings. Stir constantly with a whisk or wooden spoon and cook for 1–2 minutes, until the flour turns a light golden brown color.
4. Slowly pour in 2 cups of milk while whisking to prevent lumps. Continue whisking until the gravy starts to thicken – this takes about 5–7 minutes. If the gravy is too thick, add more milk as needed until it’s pourable.
5. Add salt and black pepper to taste. (White gravy is traditionally very peppery, but adjust to your preference.) Set aside.

6. Whisk eggs and 1 cup of cheese together in a mixing bowl.

Assemble the Casserole

1. Pour eggs and cheese over biscuits and sausage.
2. Pour the creamy sausage gravy over the egg mixture.
3. Top with the whole thing with the remaining cup of cheese.
4. Bake at 350°F for 35-45 minutes or until bubbly and golden brown.

Pro Tips

• When you cut into the Breakfast Casserole with Biscuits, if there’s liquid in the bottom, your casserole is underbaked. It’s not a huge deal but maybe note that you need to cook it a few extra minutes next time.
• This easy recipe can be cut in half and baked in a 9×7 or 8×8 baking dish. There are smaller cans of Grands Biscuits with only 5 in the can that work great for a halved recipe.

Variations

As it’s written, it’s one of our favorite breakfast casseroles but there are ways to change it up.

Different or More Protein. Instead of a Breakfast Casserole with Sausage, you can make it with Bacon. Want some extra protein? Use both bacon and sausage. Or throw extra eggs, crumbled bacon or bacon bits into the breakfast bake.

More Veggies. Want some extra veggies? Cook some diced mushrooms, peppers, or onions into the scrambled eggs.

What to Serve with this Easy Breakfast Casserole

• Fresh Fruit  or a Fruit Salad
• Hot Sauce (to spice it up!)
• Extra Gravy for the Gravy Lover – just double the recipe and reserve half for serving.
• Tall glass of orange juice or milk
• If you’re serving brunch or a variety of your favorite breakfast recipes, this would be great with cinnamon rolls for a sweet and savory combination.

Storage Instructions

Store leftovers of the sausage gravy casserole in an airtight container or cover the baking dish with plastic wrap or aluminum foil. It can be reheated in the microwave or in an air fryer if you want it to be crispy again. 

The leftovers are great for a simple Sunday morning breakfast or busy mornings before school. It’s a family favorite any day of the week.
