Biscuits and gravy casserole turns a familiar breakfast into a generous 9-by-13-inch bake with tender flaky biscuits, seasoned pork sausage, eggs, Colby Jack, and creamy pan gravy. Every layer has a job: biscuits form the base, sausage brings savory flavor, eggs hold the casserole together, and gravy keeps the center moist.
The recipe serves eight and takes about 70 minutes, including 30 minutes of preparation and 35 to 45 minutes in a 350°F oven. Making the gravy in the sausage skillet preserves the browned flavor, while a short rest after baking allows clean slices. Maple sausage and a light syrup drizzle are optional sweet-savory touches.
Ingredients for Biscuits and Gravy Casserole
For the sausage gravy, use 1 pound ground pork sausage, preferably maple flavored, 3 tablespoons butter plus more for the dish, 1/4 cup all-purpose flour, 2 cups milk, 2 teaspoons Cajun seasoning, and salt and pepper to taste.
The casserole needs one 16-ounce tube containing eight flaky-layer biscuits, 2 cups shredded Colby Jack, 6 large eggs, 1/2 cup half-and-half, 1/2 teaspoon cracked black pepper, and 1/4 teaspoon salt. Pancake or maple syrup may be offered at the table. Because sausage, cheese, Cajun blends, and biscuits already contain salt, season the gravy gradually.

How to Make Biscuits and Gravy Casserole
- Prepare the dish. Heat the oven to 350°F and butter a 9-by-13-inch baking dish.
- Brown the sausage. Crumble it over medium-low heat until fully cooked, then transfer it to a plate while leaving the drippings.
- Make the gravy. Melt butter in the pan, whisk in flour for one minute, then gradually whisk in milk. Scrape up the browned bits and season.
- Layer. Press biscuits across the dish, scatter sausage over them, and add the cheese.
- Add eggs. Whisk eggs, half-and-half, salt, and pepper, then pour evenly from edge to edge.
- Finish with gravy. Spread gravy over the entire surface.
- Bake. Cook for 35 to 45 minutes until puffed, golden, and set in the center.
- Rest. Wait 10 minutes before slicing and serve warm, with syrup if desired.

Brown the Sausage Gently
Medium-low heat gives the pork time to brown without burning the flavorful drippings needed for gravy. Break the meat into small crumbles so it spreads evenly through every slice.
Cook until no pink remains and the sausage reaches 160°F. Move it to a clean plate with a slotted spoon. If the skillet contains an unusually large pool of fat, remove some but keep the browned residue.

Build a Smooth Pan Gravy
Melt the butter in the sausage skillet, sprinkle flour evenly over it, and whisk for about one minute. This cooks away the raw flour taste while preserving the pan's browned flavor.
Add milk gradually rather than all at once, whisking after each addition until smooth. Scrape the bottom as the gravy thickens. It should coat a spoon but still flow easily enough to spread over the casserole.
Cover the Dish With Biscuits
Arrange the eight biscuits over the buttered dish and press them down gently so they cover most of the base. Small gaps are fine because the dough expands in the oven.
Avoid stacking thick sections of dough. An even base cooks more predictably and absorbs the egg mixture without leaving a raw center. Keep the biscuit dough cold until the other components are ready.
Layer Sausage and Cheese Evenly
Scatter the cooked sausage over the biscuit layer, paying attention to corners and edges. Follow with shredded Colby Jack so the cheese melts through the meat rather than forming one heavy cap.
Freshly grated cheese melts especially smoothly, although packaged shredded cheese works. A blend of mild cheddar and Monterey Jack can replace Colby Jack without changing the method.
Pour the Egg Mixture Edge to Edge
Whisk the six eggs until the whites and yolks are fully combined, then mix in half-and-half, pepper, and salt. Pour slowly across the entire dish instead of concentrating it in the center.
Pause briefly so the liquid can settle around the biscuit pieces. If one corner looks dry, tilt the dish slightly or guide a little mixture toward it with a spoon.
Add Gravy as the Final Layer
Spoon or pour the warm gravy over the egg and cheese layer, then spread it carefully to the edges. Thick mounds can delay cooking underneath, so aim for an even blanket.
The gravy may look loose before baking, but flour and eggs both continue to set in the oven. Do not add extra flour at this stage or the finished casserole can become pasty.
Know When the Center Is Done
Begin checking at 35 minutes. The top should be puffed and golden, the edges should look set, and the center should not ripple like liquid when the dish is moved gently.
If the surface browns before the middle sets, cover loosely with foil and continue baking. For food safety, the egg-rich center should reach 160°F. Remove the foil for the final few minutes if more color is needed.
Rest Before Slicing
Let the casserole stand for about 10 minutes after it leaves the oven. Residual heat finishes setting the egg and gravy, making each portion easier to lift without losing the layers.
Cut with a thin sharp knife and use a broad spatula for serving. Offer maple or pancake syrup separately so guests can choose the sweet-savory contrast without softening every piece.
Make-Ahead Options
Brown the sausage and prepare the gravy one day ahead, then refrigerate them separately. Rewarm the gravy gently with a splash of milk so it pours easily before assembly.
For the best biscuit texture, assemble the casserole shortly before baking rather than leaving raw dough submerged overnight. Eggs and cheese may be measured in advance and kept chilled.
Storage and Reheating
Cover and refrigerate leftovers within two hours for up to three days. Reheat individual portions in a moderate oven or covered skillet until steaming throughout. A microwave works, though the biscuit edges will be softer.
Freeze fully cooled portions in airtight wrapping for up to two months. Thaw overnight in the refrigerator before reheating so the center warms without drying the outside.
Troubleshooting
- Gravy is lumpy: Add milk slowly and whisk continuously.
- Center stays wet: Cover the browned top and continue baking.
- Biscuits are doughy: Press them into one even layer without stacking.
- Casserole tastes too salty: Reduce added salt and check the Cajun blend.
- Slices collapse: Give the baked casserole its full resting time.
Conclusion
Brown pork sausage and use its skillet to make a smooth milk gravy. Press flaky biscuits across a buttered dish, layer with sausage and Colby Jack, pour over seasoned eggs, finish with gravy, and bake at 350°F until golden and set. Rest before slicing.
Frequently Asked Questions
- → Can I assemble biscuits and gravy casserole the night before?
Prepare the sausage and gravy ahead, but assemble shortly before baking for the best biscuit texture.
- → How do I know the casserole is fully cooked?
The center should be set rather than liquid, and an instant-read thermometer should register 160°F.
- → Can I use a different cheese?
Yes. Mild cheddar, Monterey Jack, or a blend can replace Colby Jack.
- → Does the casserole need maple syrup?
No. It is optional and best served at the table for anyone who likes a sweet-savory finish.
