Sausage Gravy And Biscuit Casserole takes the classic Southern breakfast plate and turns it into one bubbling, golden-topped bake you can scoop with a spoon. Instead of pouring gravy over split biscuits at the table, the gravy soaks right into the layers, so every bite is creamy, savory, and biscuit-rich.

The trick is par-baking the biscuit layer first so the bottom stays tender instead of turning to paste, then finishing the casserole under high heat so the top biscuits crisp at the edges. A pound of breakfast sausage, a roux of butter and flour, and whole milk give you a gravy thick enough to hold its shape when you cut a square.
It feeds a crowd, travels to potlucks in the same dish, and can be assembled the night before and baked straight from the fridge. Serve it with hot sauce, scrambled eggs, and strong coffee for a weekend breakfast that feels like a diner booth at home.
Why You'll Love This Recipe
About the Ingredients
1 lb (454g) bulk breakfast sausage (mild or hot)
Bulk sausage saves you the step of removing casings. If you only have links, slit the casings and crumble the meat; ground pork plus 1 teaspoon poultry seasoning is a solid substitute.
1/4 cup (57g) unsalted butter
Butter builds the roux that thickens the gravy. Salted butter works if you cut the added salt in half at the end.
1/3 cup (42g) all-purpose flour
Flour is the thickening agent here, so don't swap in cornstarch, which gives a glossy, slippery gravy. Measure by spooning into the cup, not scooping.
3 cups (720ml) whole milk, divided
Whole milk gives the creamiest body; 2% works but the gravy will be slightly thinner. Add 1/2 cup extra if you like a looser gravy.
1 teaspoon kosher salt, plus more to taste
Kosher salt flakes season more evenly than table salt. Taste the gravy after the sausage goes back in, since sausage brands vary wildly in salt.
1 1/2 teaspoons freshly ground black pepper
Sausage gravy is a pepper-forward dish, so grind it fresh. Pre-ground pepper tastes flat and dusty by comparison.
1/2 teaspoon garlic powder
Garlic powder blends into the gravy without burning, unlike fresh garlic. Onion powder can stand in if that's what's in your spice drawer.
1/4 teaspoon cayenne pepper (optional)
Cayenne adds warmth without real heat. Smoked paprika is a milder, smokier swap if you're feeding kids.
1 can (16.3 oz / 462g) refrigerated flaky biscuits (8 count)
Refrigerated biscuits keep this a weeknight recipe; frozen biscuits work too, just add 5 minutes to the first bake. Homemade drop biscuits are even better if you have 15 extra minutes.
2 cups (226g) shredded sharp cheddar cheese, divided
Sharp cheddar cuts through the rich gravy. White cheddar or a Monterey Jack blend melts just as well.
2 large eggs
Eggs bind the layers so the casserole slices cleanly. Flax eggs (2 tablespoons ground flax plus 6 tablespoons water) work for an egg-free version.
Cooking spray or 1 tablespoon softened butter, for the dish
Greasing generously is what lets you lift out the first square intact. Butter adds a faint toasty flavor that spray doesn't.
Tips & Tricks
Don't Skip the Par-Bake
Baking the bottom biscuit layer for 10 minutes before adding gravy is the single step that prevents a soggy, doughy base.
Thicken Gravy Off the Heat
Whisk the flour into the fat and cook it 1 to 2 minutes until it smells nutty, then add milk slowly, or you'll get lumps.
Let It Rest Before Cutting
Ten minutes out of the oven lets the gravy set so squares hold together instead of running across the plate.
Season at the End
Sausage is salty, so taste the finished gravy before adding more salt. You can always add, never subtract.
Pro Tips
Step-by-Step Instructions
1. Heat Oven and Prep Dish
Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish with cooking spray or softened butter. A glass dish lets you monitor the bubbling gravy without opening the oven.
2. Brown the Sausage
Cook the sausage in a large skillet over medium-high heat for 6 to 8 minutes, breaking it into small crumbles with a wooden spoon, until no pink remains and the edges are deeply browned. Transfer the sausage to a plate with a slotted spoon, leaving the rendered fat in the pan.
3. Build the Roux
Add the butter to the pan and melt over medium heat, then whisk in the flour, garlic powder, black pepper, salt, and cayenne. Cook for 1 to 2 minutes, whisking constantly, until the mixture smells nutty and turns pale golden, this cooks out the raw flour taste.
4. Whisk in the Milk
Pour in 2 1/2 cups of the milk in a steady stream, whisking constantly to prevent lumps. Simmer for 4 to 5 minutes, whisking often, until the gravy coats the back of a spoon and bubbles lazily at the edges; it will look thin but thickens as it bakes.
5. Finish the Gravy
Return the sausage to the pan, stir in 1 cup of the cheddar, and taste for salt. If the gravy is thicker than warm honey, whisk in the reserved 1/2 cup milk, then set the pan aside off the heat.
6. Par-Bake the Biscuit Base
Separate the biscuits and tear each one in half horizontally. Press half of them into an even layer in the prepared dish and bake at 375°F (190°C) for 10 minutes, until the tops look dry and slightly puffed.
7. Layer and Assemble
Scatter the remaining torn biscuit pieces over the par-baked base, then pour the warm sausage gravy evenly over the top. Whisk the eggs with a pinch of salt and drizzle them over the casserole, then finish with the remaining 1 cup cheddar.
8. Bake Until Bubbling
Bake at 375°F (190°C) for 25 to 30 minutes, until the gravy bubbles vigorously around the edges and the cheese is melted and golden. The center should read 165°F (74°C) on an instant-read thermometer.
9. Rest and Serve
Let the casserole rest for 10 minutes so the gravy sets, then cut into 6 squares and serve hot with hot sauce or sliced scallions. Leftovers reheat beautifully, so don't worry about finishing the pan.
Delicious Variations
Spicy Chorizo Version
Swap the breakfast sausage for Mexican chorizo and the cheddar for pepper Jack, then finish with pickled jalapeños for a Tex-Mex brunch bake.
Mushroom and Herb (Meatless)
Replace the sausage with 1 pound of cremini mushrooms browned in butter, add 1 teaspoon dried thyme, and use vegetable broth in place of 1 cup of the milk.
Bacon Maple Twist
Use crumbled bacon instead of sausage and stir 1 tablespoon maple syrup into the gravy for a sweet-salty take that's unreal with a fried egg on top.
How to Store Sausage Gravy And Biscuit Casserole
Refrigerator
Cool within 2 hours, cover tightly, and refrigerate for up to 4 days. The gravy thickens cold, which is normal.
Freezer
Wrap individual cooled squares tightly in plastic and foil, then freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat covered with foil at 350°F (175°C) for 15 to 20 minutes, or microwave single squares for 90 seconds. Add a splash of milk if the gravy looks dry.
Frequently Asked Questions
Q: Can I make sausage gravy and biscuit casserole the night before?
Yes, assemble the casserole completely, cover it, and refrigerate for up to 24 hours before baking. Add 10 to 15 minutes to the bake time since it goes into the oven cold, and cover with foil for the first 15 minutes so the top doesn't over-brown.
Q: Why is my biscuit casserole soggy on the bottom?
The bottom turns soggy when the biscuit layer isn't par-baked and the gravy is too thin. Par-baking the base for 10 minutes creates a moisture barrier, and simmering the gravy until it coats a spoon ensures it sets rather than soaks in.
Q: Can I use canned biscuits or should I make homemade ones?
Refrigerated canned biscuits work perfectly and keep this a 50-minute recipe, while homemade drop biscuits give you a fluffier, more buttery result. If using frozen biscuits, par-bake them 5 minutes longer before adding the gravy.
Q: How do I know when the casserole is fully cooked?
The casserole is done when the gravy bubbles steadily around the edges and the center registers 165°F (74°C) on an instant-read thermometer. Visual cues alone can fool you because the cheese browns before the egg layer sets.
Q: Can I freeze sausage gravy and biscuit casserole?
Yes, freeze fully baked and cooled squares wrapped tightly for up to 2 months. The texture of the biscuits softens slightly after freezing, so thaw overnight in the fridge and reheat covered at 350°F (175°C) to bring back the creamy consistency.
