What Is Biscuits and Gravy with Eggs and Sausage Breakfast Casserole?
This casserole starts with biscuit mix and crumbled breakfast sausage as the base, which is topped with a custard of eggs and milk and finished with a blanket of shredded cheese. The sausage brings savory, spiced meatiness, while the biscuit mix soaks up the egg-milk custard and bakes into tender pockets. The overall flavor is rich and comforting — think warm, slightly salty sausage bites, creamy egg, and gooey cheese with a soft biscuit foundation.
The cooking method is straightforward baking: brown the sausage on the stovetop, toss it with the dry biscuit mix, pour over the whisked eggs and milk, and bake until set. It’s typically served for breakfast or brunch, but it’s hearty enough for a casual dinner too. The vibe is classic comfort food — ideal for slow weekend mornings, holiday brunches, or anytime you want something reliably filling and nostalgic.

Ingredients for Biscuits and Gravy with Eggs and Sausage Breakfast Casserole
For the Base
- 2 cups biscuit mix
For the Sausage
- 1 pound breakfast sausage
For the Egg Mixture
- 6 eggs
- 2 cups milk
- Salt and pepper to taste
For Topping
- 2 cups shredded cheese
For Serving (optional)
- 1 cup gravy (optional, for serving)
Ingredient Notes (Substitutions, Healthy Swaps)
- Biscuit mix: You can use any all-purpose baking mix or a store brand biscuit mix. For a gluten-free option, use a gluten-free baking mix labeled as a biscuit/pancake mix — texture will be slightly different but still tasty.
- Breakfast sausage: Keep the same amount but choose a lower-fat turkey or chicken breakfast sausage if you want a lighter version. Keep seasonings in mind, as turkey sausage can be milder.
- Eggs and milk: For a lighter custard, use low-fat or 2% milk. For dairy-free, substitute with an unsweetened soy or oat milk (optional swap — see Pro Tips).
- Cheese: Use your favorite melting cheese; sharp cheddar adds tang, while Monterey Jack melts very smoothly. For lower-fat swaps, use a reduced-fat shredded cheese.
- Gravy: The recipe lists gravy as optional for serving; choose a sausage gravy or a simple store-bought style warmed through.
Step-by-Step Instructions
Step 1 – Brown the Sausage
- Preheat the oven to 350°F (175°C).
- In a skillet over medium heat, brown the breakfast sausage, breaking it into small crumbles until cooked through.
- Drain any excess fat.
Visual cue: The sausage should be evenly browned with no pink remaining and have small, separate crumbles.
Pro cue: Don’t overcook until dry — slightly moist crumbles will stay juicy in the casserole.
Step 2 – Combine Biscuit Mix and Sausage
- In a large bowl, combine the 2 cups biscuit mix with the cooked sausage, tossing so the meat is evenly distributed.
Visual cue: The biscuit mix will look coated with bits of sausage, with no large clumps.
Pro cue: Toss gently but thoroughly so each spoonful gets a balance of biscuit and sausage.
Step 3 – Whisk the Eggs and Milk
- In another bowl, whisk together the 6 eggs, 2 cups milk, and salt and pepper to taste until smooth and slightly frothy.
Visual cue: The mixture should be homogenous with small bubbles from whisking.
Pro cue: Whisk until well combined — this helps create a silky custard that soaks the biscuit mix evenly.
Step 4 – Assemble the Casserole
- Grease a baking dish and spread the sausage-biscuit mixture on the bottom in an even layer.
- Pour the egg mixture on top, pressing lightly to help the biscuit mix absorb the custard.
Visual cue: The liquid should just cover the biscuit mix and settle into gaps; no dry patches visible.
Pro cue: Press gently but avoid compacting too tightly; you want the custard to permeate.
Step 5 – Top with Cheese and Bake
- Sprinkle 2 cups shredded cheese evenly over the top.
- Bake for 25–30 minutes until the custard is set and the cheese is golden.
- Let the casserole rest for a few minutes, slice, and serve warm with gravy if desired.
Visual cue: The center should be set (no jiggle) and the cheese should be melted and lightly golden around the edges.
Pro cue: A short rest after baking helps the slices hold together when plated.
Pro Tips for Success
- Heat control: Brown the sausage over medium heat to get a nice sear without burning the edges.
- Custard absorption: Let the assembled casserole sit 5–10 minutes before baking if the biscuit mix seems dry — it will absorb the egg mixture better.
- Even baking: Use an oven rack in the center position for even heat distribution.
- Doneness test: The casserole is done when the center doesn’t jiggle and a knife inserted in the middle comes out clean.
- Season carefully: Biscuit mix and sausage can be salty; taste the sausage before adding a lot of extra salt to the eggs.
- Cheese placement: If you want a crisper top, broil for 1–2 minutes at the end — watch closely to avoid burning.
- Dairy alternatives: If using plant-based milk, choose an unsweetened variety and check melting behavior — cheese flavor might differ with non-dairy swaps.
Flavor Variations (OPTIONAL)
- OPTIONAL — Spicy kick: Stir 1/2 to 1 teaspoon crushed red pepper into the egg mixture or use a spicy breakfast sausage.
- OPTIONAL — Herb-forward: Add 1–2 tablespoons chopped fresh parsley or chives on top after baking for brightness.
- OPTIONAL — Extra-cheesy: Mix 1 cup cheese into the biscuit-sausage layer and 1 cup on top for extra molten cheese throughout.
- OPTIONAL — Lighter version: Use turkey breakfast sausage and 2% milk, and reduce cheese to 1 cup.
- OPTIONAL — Vegetarian-ish: Substitute sausage with a plant-based breakfast sausage crumble (keep the rest of the recipe the same).
Serving Suggestions
- Serve slices with warm gravy spooned over the top for a classic biscuits-and-gravy experience.
- Pair with a simple green salad or fruit salad to balance richness.
- Offer hot sauce, ketchup, or a side of salsa for guests who like tangy or spicy additions.
- Plate with a side of roasted potatoes or hash browns for a heartier brunch spread.
- For breakfast-for-dinner, serve with steamed or sautéed greens to add color and nutrition.
- Garnish with chopped fresh herbs or extra shredded cheese for a pretty presentation.
Make-Ahead, Storage & Reheating
- Make-ahead: Assemble the casserole (up through Step 4) and cover tightly with plastic wrap or foil. Refrigerate up to 24 hours before baking. Let sit at room temperature 15–20 minutes before baking, then bake as directed.
- Refrigeration: Store cooled leftovers in an airtight container for 3–4 days.
- Reheating (oven): Preheat oven to 350°F (175°C), place slices on a baking sheet, cover with foil to retain moisture, and heat 10–15 minutes until warmed through.
- Reheating (microwave): Microwave individual slices on a microwave-safe plate for 1–2 minutes, rotating halfway, until hot. Note texture will be softer and less crispy than oven reheating.
- Texture note: Custardy casseroles firm up when chilled; warm gently to restore a soft texture without drying out.
Storage and Freezing Instructions
- Freezing assembled (uncooked): You can freeze the assembled casserole (before baking) in a freezer-safe dish for up to 2 months. Wrap tightly in plastic and foil to prevent freezer burn. Thaw in the refrigerator overnight before baking; add extra 5–10 minutes to baking time if still cool in the center.
- Freezing cooked leftovers: Baked slices freeze well for up to 2 months. Wrap pieces individually or layer with parchment in a freezer container. Thaw overnight in the fridge and reheat in the oven covered with foil.
- If you prefer not to freeze: Keep refrigerated up to 4 days and reheat as needed — freezing is recommended only if you want longer storage and don’t mind a slight change in texture.

FAQ About Biscuits and Gravy with Eggs and Sausage Breakfast Casserole
Q: Why is my casserole soggy in the middle?
A: Sogginess often means the biscuit mix didn’t have enough time to absorb the egg mixture. Let the assembled dish sit 5–10 minutes before baking and be sure the egg mixture covers the biscuit but isn’t overly liquidy. Bake until the center is set.
Q: How can I tell when it’s fully cooked?
A: The center should no longer jiggle. Insert a knife in the center — it should come out mostly clean. If it’s still runny, give it another 5–7 minutes and check again.
Q: Can I use low-fat milk or a non-dairy milk?
A: Yes — 2% or low-fat milk will work and produce a slightly lighter custard. Unsweetened soy or oat milk can be used as dairy-free options; texture may change slightly.
Q: How long does this keep in the fridge?
A: Store leftovers in an airtight container for 3–4 days.
Q: Can I make this ahead for a brunch?
A: Absolutely. Assemble the casserole, cover, and refrigerate up to 24 hours — then bake before serving.
Q: Will it freeze well?
A: Yes. Both assembled (uncooked) and cooked portions freeze well for up to 2 months. Thaw overnight before baking or reheating.
Notes
- Slice with a sharp serrated knife for clean edges and neat presentation.
- Add a sprinkle of fresh herbs or cracked black pepper just before serving for visual contrast and flavor lift.
- If your biscuit mix is particularly salty, reduce added salt in the egg mixture and rely on taste after baking.
- For extra richness, warm your gravy and spoon over hot slices just before serving.
- If you prefer a crisper top, finish under the broiler for 1–2 minutes but watch closely to prevent burning.
