Biscuit and Gravy Casserole is a hearty breakfast bake with tender biscuit pieces, savory sausage, fluffy eggs, and creamy gravy. It comes together in one dish, feeds a crowd, and works beautifully for relaxed weekends, holidays, or brunch gatherings.
When you want a filling breakfast without juggling several pans at once, this casserole is a practical choice. Everything you love about biscuits, sausage, eggs, and gravy is layered into a single baking dish, so every serving gets a little of each component.
The combination works especially well because the biscuit pieces soak up some of the egg mixture and gravy while they bake. They become tender underneath while the exposed edges turn lightly golden, giving the casserole a satisfying mix of soft and slightly crisp textures.
It is also a convenient option when you are serving several people. Once the sausage and gravy are prepared, assembly is straightforward, and the oven handles the rest while you prepare coffee, fruit, or other breakfast sides.
Biscuit and Gravy Casserole Ingredients
Breakfast sausage: One pound of ground breakfast sausage creates the savory base of the casserole. Crumbling it into smaller pieces helps distribute the meat evenly through every slice.
Refrigerated biscuits: A package of chilled biscuits makes the casserole quick to assemble. Cutting each biscuit into quarters allows the dough to bake more evenly and gives the egg and gravy space to settle around it.
Large eggs: Five beaten eggs bind the biscuit and sausage layers together and provide the soft breakfast-casserole texture.
Milk: A small amount of milk loosens the beaten eggs and helps them cook into a tender, fluffy layer rather than becoming dense.
Prepared sausage gravy: One packet of gravy mix, prepared according to its package directions, provides the creamy finishing layer. The gravy flows between the sausage and biscuit pieces as the casserole bakes.
Cooking Steps
STEP 1: Preheat your oven to 350°F (175°C). Lightly coat a 9 × 13-inch baking dish with nonstick cooking spray, making sure the bottom and sides are covered so the biscuit pieces release easily after baking.
STEP 2: Place the ground breakfast sausage in a large skillet over medium heat. Cook it until completely browned with no pink remaining, breaking the meat into small crumbles as it cooks. Smaller pieces are preferable because they spread more evenly throughout the casserole.
STEP 3: While the sausage cooks, whisk the five eggs with 1/2 cup of milk in a medium bowl. Continue whisking until the yolks and whites are completely blended and the milk is evenly incorporated.
STEP 4: Prepare the packet of gravy according to its package directions. Most packaged gravy mixes are combined with water and heated until bubbling and thickened. Keep the finished gravy warm while you assemble the casserole so it remains easy to pour.
STEP 5: Open the refrigerated biscuits and cut each biscuit into four pieces. Arrange the biscuit quarters across the bottom of your prepared baking dish in a fairly even layer. They do not need to be perfectly aligned because they will expand while baking.
STEP 6: Scatter the browned breakfast sausage over the biscuit pieces. Slowly pour the egg and milk mixture over the sausage and biscuits, moving around the baking dish as you pour so the liquid reaches as much of the casserole as possible.
STEP 7: Spoon or pour the prepared gravy evenly over the top. Transfer the baking dish to the preheated oven and bake for about 40 minutes. The casserole is ready when the eggs are set, the biscuits are cooked through, and the top has developed a lightly golden finish.
STEP 8: Remove the casserole from the oven and allow it to rest for 10 minutes before slicing. This short resting period lets the egg layer firm slightly and gives the gravy time to settle, making the casserole much easier to portion neatly.
What to Serve with Biscuit and Gravy Casserole
Because this breakfast casserole is already rich and substantial, simple sides work especially well.
- Fresh fruit: Berries, melon, grapes, or a mixed fruit bowl provide a fresh contrast to the sausage and creamy gravy.
- Breakfast potatoes: Crispy roasted or skillet potatoes make the meal even heartier when you are serving brunch for a crowd.
- Simple green salad: For a brunch-style meal, lightly dressed greens add freshness without competing with the casserole.
Can I assemble this casserole ahead of time?
You can prepare some of the components in advance, especially the sausage and gravy. Refrigerate them separately, then assemble the casserole closer to baking time. Refrigerated biscuit dough begins changing once opened, so keeping the biscuits sealed until you are ready to assemble generally gives the most reliable texture.
How do I know when the biscuits are cooked through?
Check the center of the casserole rather than relying only on the golden surface. The egg mixture should be completely set, and biscuit pieces in the middle should no longer look wet or doughy. If necessary, continue baking for a few additional minutes and check again.
Can I use a different type of breakfast sausage?
Yes. Any ground breakfast-style sausage that cooks into loose crumbles can work well. The final flavor will depend heavily on the sausage you choose, so use one with a seasoning level that suits your household. Be sure to cook it completely before layering it into the casserole.
Why should the casserole rest before serving?
Resting for about 10 minutes gives the hot egg, biscuit, and gravy layers a chance to settle. Cutting immediately after baking can cause portions to fall apart and the gravy to spread across the dish. A brief rest produces cleaner slices while keeping the casserole warm.
Can Biscuit and Gravy Casserole be frozen?
Yes, although the texture of the biscuits and gravy can become slightly softer after freezing and reheating. For the best results, cool the baked casserole completely before wrapping individual portions or the entire dish securely for freezer storage.
Helpful Tips
- Break the sausage into small crumbles. Large chunks make the casserole harder to portion evenly, while smaller pieces ensure sausage is distributed throughout the baking dish.
- Spread the gravy all the way across the top. Even coverage helps keep the casserole moist and ensures each serving contains plenty of creamy gravy.
- Give the center enough time to bake. A 9 × 13-inch casserole can look finished around the edges before the center is fully set, so check the middle before removing it from the oven.
How to Store & Reheat
Let leftover casserole cool before transferring it to an airtight container. Refrigerate it for up to 3 to 4 days. Keeping individual slices in separate containers can make reheating quick and convenient for weekday breakfasts.
For longer storage, freeze cooled portions in freezer-safe containers or wrap them securely before placing them in a freezer bag. For the best texture, use frozen casserole within about 2 months. Thaw portions overnight in the refrigerator before reheating whenever possible.
To reheat a single serving, place it on a microwave-safe plate and heat in short intervals until hot throughout. Microwave times will vary depending on the size and thickness of the portion.
For several servings, place the casserole in an oven-safe dish, cover loosely to prevent excessive drying, and warm at about 325°F until heated through. If the casserole seems slightly dry after refrigeration, serving it with a little extra warm gravy can restore some of the creamy texture.
This casserole is especially useful for mornings when you want familiar breakfast flavors in a format that is simple to serve. The biscuits provide a tender base, the seasoned sausage makes every portion satisfying, and the eggs and gravy bring everything together into one warm, comforting brunch dish.

- Distribute the cooked breakfast sausage uniformly over the biscuit layer.
- Pour the egg-and-milk mixture evenly over the biscuits and sausage.
- Cover the casserole with the prepared gravy, spreading it across the top so the layers beneath are evenly coated.
