Can I make the biscuits and gravy breakfast casserole the night before?

Yes! This casserole is perfect for prepping ahead. Simply assemble the entire dish as instructed (without baking), cover tightly with plastic wrap or foil, and refrigerate overnight. In the morning, bake as directed, adding an extra 5–10 minutes to ensure it's cooked through. This makes it a great option for holiday mornings or hosting brunch.

Can I freeze the casserole for later?

Absolutely. You can freeze the unbaked casserole for up to 3 months by wrapping it tightly in plastic wrap and foil. When ready to use, thaw overnight in the refrigerator and bake as usual. You can also freeze baked leftovers in airtight containers — just reheat in the oven or microwave until warmed through. The texture holds up beautifully!

What’s the best type of sausage for this recipe?

A savory breakfast sausage (like pork sausage) is classic and adds the most authentic flavor. However, you can easily swap it with turkey sausage, spicy Italian sausage, or even vegetarian sausage crumbles depending on your preferences. Choose a sausage that brings flavor and complements the creamy gravy and fluffy biscuits.

Instructions

Preheat oven to 350°F (175°C).
In a large skillet over medium heat, cook the sausage until browned and fully cooked, breaking it into crumbles. Remove from heat and set aside.
Prepare the country gravy in the same skillet according to package directions until thickened.
In a mixing bowl, whisk together eggs, milk, garlic powder, and black pepper. Add cooked sausage and 1 cup of shredded cheese. Stir well.
Cut each biscuit into quarters and layer evenly on the bottom of a greased 9×13-inch baking dish.
Pour the egg and sausage mixture evenly over the biscuit layer.
Pour the prepared gravy over the top and sprinkle with the remaining 1 cup of shredded cheese.
Bake for 25–30 minutes, or until eggs are set and biscuits are golden.
Let cool for 5–10 minutes before slicing and serving.

Notes

Do not overcook the sausage – just brown it until no longer pink.
Let the casserole rest before slicing to help it set.
Use spicy sausage or add hot sauce for a kick.
Can be prepped the night before and baked fresh in the morning.
Store leftovers in an airtight container in the fridge for up to 3 days.
