What Is Biscuits and Gravy Casserole?
Biscuits and Gravy Casserole takes the beloved Southern pairing of biscuits and sausage gravy and turns it into a layered bake. Instead of individually split biscuits smothered in gravy, this casserole presses refrigerated biscuit dough into a single crust, tops it with crumbled breakfast sausage, pours an egg-and-milk custard over the meat, and finishes with prepared sausage gravy and melted cheese. The result is creamy, hearty, and deeply comforting—think soft biscuit bread, savory meat pockets, and silky gravy all in one sliceable pan.
This is a baked method (350°F for 35 minutes) that yields golden edges and a set custard center. Folks typically serve it for breakfast or brunch, but it’s substantial enough for dinner. It’s the kind of dish you make when you want something homey, hands-off, and universally loved.
Ingredients for Biscuits and Gravy Casserole
For the Base
- 10 oz refrigerated buttermilk biscuits (one can, usually 8–10 biscuits)
- Butter or nonstick spray for greasing the pan
For the Sausage Layer
- 1 lb breakfast sausage (pork or turkey)
For the Custard
- 6 large eggs
- 1/2 cup whole milk (or 2% milk or unsweetened plant milk)
- 1 tsp salt
- 1 tsp freshly ground black pepper
For the Cheese
- 2 cups shredded cheese, divided (cheddar or cheddar/Monterey Jack blend)
For the Gravy
- 1 packet (2.75 oz) sausage gravy mix
- 2 cups water (for making the gravy)
Ingredient Notes (Substitutions, Healthy Swaps)
- Milk: Whole milk gives a rich custard; use 2% or an unsweetened plant milk (soy or oat) if you prefer lower fat or dairy-free options.
- Sausage: The recipe accepts pork or turkey breakfast sausage. Turkey sausage reduces fat and keeps the flavor profile similar.
- Cheese: Cheddar or a cheddar/Monterey Jack blend works best for melting and flavor. Lower-fat cheeses will melt differently but are acceptable.
- Biscuits: Use the canned refrigerated biscuits as directed. For a gluten-free option, look for a certified gluten-free refrigerated biscuit product—note texture may differ.
- Gravy mix: Use the packet specified in the ingredients. If you opt to make homemade gravy, keep it optional and note it will change prep time and proportions.
- Salt & pepper: The packaged gravy adds seasoning; the 1 tsp of salt plus pepper in the custard helps balance flavors—adjust to taste.
Step-by-Step Instructions
Step 1 – Prepare and preheat
Preheat the oven to 350°F and grease a 9×13-inch baking pan with butter or nonstick spray.
Visual cue: The pan should be evenly greased with no dry spots so the biscuit crust won’t stick.
Step 2 – Make the biscuit crust
Press the refrigerated biscuit dough evenly across the bottom of the greased pan to make a single-layer crust.
Visual cue: The biscuits should form a mostly even sheet with seams pressed together; it’s okay if a few edges overlap slightly.
Pro cue: Work quickly so the dough remains chilled—this helps the edges puff and bake up tender.
Step 3 – Brown the sausage
Heat a skillet over medium-high. Brown the breakfast sausage until cooked through, breaking it into small pieces. Drain excess grease, then spread the cooked sausage evenly over the biscuit crust.
Visual cue: Sausage should be golden-brown with small, crumbly pieces spread across the crust.
Pro cue: Don’t overbake the sausage in the pan—just brown it enough to develop flavor, then drain to prevent greasiness.
Step 4 – Whisk and pour the custard
In a medium bowl, whisk together the eggs, milk, salt, and pepper until smooth, then pour the mixture evenly over the sausage layer.
Visual cue: The egg mixture will seep between sausage pieces and slightly into the biscuit layer—this is normal.
Pro cue: Strain the egg mixture through a fine mesh if you want an extra-smooth custard, especially if your eggs are unevenly beaten.
Step 5 – Add cheese and gravy
Sprinkle 1 cup of the shredded cheese over the egg mixture. Prepare the sausage gravy according to the packet instructions with 2 cups of water until thickened; let cool slightly, then pour it evenly over the casserole. Top with the remaining 1 cup cheese.
Visual cue: The casserole should be evenly covered in gravy and a final blanket of cheese before baking.
Pro cue: Let the gravy cool just enough that it won’t scramble the egg mixture—warm, not piping hot, is ideal.
Step 6 – Bake and rest
Bake for 35 minutes until set and the top is golden. Let rest for 10 minutes before slicing and serving.
Visual cue: The center should be set (not jiggly) and the cheese golden-bubbly on top.
Pro cue: Resting allows the custard to finish setting and makes cleaner slices.
Pro Tips for Success
- Temperature control: Keep biscuit dough chilled until you press it into the pan to preserve tenderness and puff.
- Even browning: Brown the sausage over medium-high so it develops a slight crust; this adds flavor without overcooking.
- Drain well: Remove excess grease from sausage to prevent a soggy crust.
- Gravy temperature: Cool the gravy slightly before pouring—too hot and it can overcook the eggs.
- Cheese distribution: Splitting cheese into two layers (one under the gravy and one on top) gives melty pulls and a golden finish.
- Doneness test: A slight jiggle in the center is okay, but the custard should not be liquid; it will firm as it rests.
- Clean slices: Let the casserole rest 10 minutes before slicing so pieces hold together better.
Flavor Variations
All of these are OPTIONAL and keep the base recipe intact.
- OPTIONAL Spicy kick: Use a spicy breakfast sausage or fold 1/2 tsp crushed red pepper into the egg mixture for heat.
- OPTIONAL Herb lift: Stir 1 tbsp finely chopped fresh chives or parsley into the custard before pouring.
- OPTIONAL Extra-cheesy: Increase to 2 1/2–3 cups cheese if you want a cheesier casserole.
- OPTIONAL Lighter version: Use turkey sausage and 2% milk to cut fat while keeping the same structure.
- OPTIONAL Vegetarian swap: Use a plant-based breakfast sausage that cooks like crumbles (be aware this changes flavor).
- OPTIONAL Smoked flavor: Choose a smoked cheddar for a subtle smoky note without changing the method.
Serving Suggestions
- Classic brunch: Serve squares with a side of scrambled eggs and fresh fruit.
- Weekend crowd-pleaser: Pair with a simple green salad dressed in vinaigrette to cut through richness.
- Potluck idea: Slice into 12 pieces and arrange on a platter for easy self-serve.
- Comfort dinner: Add a bowl of steamed vegetables or roasted Brussels sprouts for balance.
- Breakfast for guests: Offer hot sauce, extra cheese, and warmed gravy on the side for customization.
- Party pairing: This casserole plays well alongside other easy bakes—try it with a favorite like dump-and-bake meatball casserole for variety at a brunch buffet.
Make-Ahead, Storage & Reheating
- Make-ahead assembly: You can assemble the casserole through Step 5 (up to pouring warm gravy and topping with cheese), cover tightly, and refrigerate overnight. Add 5–10 minutes to baking time if baking straight from chilled.
- Refrigerator: Store leftover slices in an airtight container for up to 3–4 days.
- Reheating (oven): Place portions in a 350°F oven covered with foil for 10–15 minutes until heated through.
- Reheating (microwave): Microwave individual slices for 1–2 minutes on medium power, checking to avoid overcooking the eggs; the texture will be softer.
- Texture changes: Custard firms as it cools; reheated pieces may be slightly denser but remain flavorful.
Storage and Freezing Instructions
- Freezing assembled (not baked): You can assemble the casserole through Step 5 and freeze it tightly wrapped for up to 1 month. Thaw overnight in the refrigerator before baking; add extra baking time as needed.
- Freezing baked leftovers: Baked casserole slices freeze okay for up to 2 months. Wrap slices individually in plastic and foil to prevent freezer burn.
- Thawing and reheating frozen: Thaw in the refrigerator overnight, then reheat in a 350°F oven until warmed through.
- If freezing is not recommended: Because the biscuit crust may become slightly denser after freezing and reheating, expect a modest change in texture—still excellent for convenience but not exactly the same as freshly baked.

FAQ About Biscuits and Gravy Casserole
Q: My custard was runny after baking—what happened?
A: The casserole likely needed more bake time or more resting time. If the center was still jiggly, return it to the oven for 5–10 more minutes and let it rest 10–15 minutes before slicing.
Q: Can I use refrigerated biscuit dough other than buttermilk?
A: You can, but textures vary. Buttermilk biscuits give the best flavor and tenderness as noted in the ingredient list.
Q: How do I prevent a soggy bottom crust?
A: Brown and drain the sausage well, keep biscuit dough chilled before baking, and don’t overpour greasy liquid. Pressing biscuits into a tight, even layer helps them bake through.
Q: Can I make this dairy-free?
A: Yes—use unsweetened plant milk in the custard and a dairy-free shredded cheese. The gravy packet may contain dairy ingredients, so check the packet or use a compatible dairy-free gravy mix.
Q: How can I reheat slices without drying them out?
A: Reheat gently in a 350°F oven covered with foil to retain moisture, checking after 10–15 minutes.
Q: Is this casserole freezer-friendly?
A: Yes—assemble and freeze before baking, or freeze baked slices. Thaw overnight and reheat in the oven for best texture.
Notes
- Presentation tip: Garnish with chopped fresh chives or parsley for a bright color contrast.
- Serving size: Cut into 8–12 squares depending on appetite—12 for smaller portions, 8 for hearty servings.
- Seasoning tweak: Taste the gravy before pouring; you can adjust salt and pepper if your gravy mix is mild.
- Crisp edges: For crisper edges, bake uncovered the full time and finish the final 2–3 minutes under the broiler—watch closely so it doesn’t burn.
- Clean slicing: Use a sharp knife dipped in hot water between cuts for neat squares.
- Crowd scaling: Double the recipe in two pans for larger gatherings or halve it for a smaller household.
