If you love the comforting, stick-to-your-ribs flavors of a diner breakfast, Biscuits and Gravy Casserole delivers exactly that in one pan. It layers a pressed refrigerated-biscuit crust with browned breakfast sausage, an egg custard, shredded cheese and a generous pour of sausage gravy — then bakes until golden and set. If you enjoy hearty morning bakes, you might also like this beef and cheese chimichangas for a different kind of savory crowd-pleaser.
Why you’ll love this dish
This casserole is pure comfort food with very little fuss. It turns common breakfast staples into a sliceable, shareable pan that’s perfect for feeding a family, bringing to a brunch potluck, or making ahead for busy weekday mornings. The biscuit base makes it fast (no dough rolling), the eggs keep it custardy instead of dry, and the gravy on top guarantees rich, saucy bites every time.
"A simple, satisfying casserole that tastes like a diner breakfast and travels well to Sunday brunch."
Aside from taste, it’s budget-friendly, kid-approved, and easy to scale up or down.
Step-by-step overview
Start by pressing the refrigerated biscuits into a crust in a 9×13 pan. Brown and drain the sausage, then spread it over the crust. Whisk eggs and milk, season, and pour over the sausage. Add a layer of shredded cheese, pour prepared sausage gravy over the casserole, top with remaining cheese, then bake about 35 minutes until set. Let it rest before cutting so slices hold together.
This overview gives you a clear rhythm: crust → sausage → egg custard → cheese → gravy → bake.
What you’ll need
- 10 oz refrigerated buttermilk biscuits (one standard tube or tin; press into a single layer)
- 1 lb breakfast sausage (pork or turkey)
- 6 large eggs
- 1/2 cup whole milk (or 2%/milk alternative)
- 2 cups shredded cheese (cheddar or cheddar/Monterey Jack blend)
- 1 tsp salt
- 1 tsp freshly ground black pepper
- 1 packet sausage gravy mix (packet usually calls for 2 cups water)
- 2 cups water (for the gravy)
- Butter or nonstick spray (for greasing the 9×13-inch pan)
Notes: Use a spicier sausage for more heat, or turkey sausage to reduce fat. If you prefer, swap the packet gravy for 1 1/2–2 cups homemade sausage gravy (see tips).
Step-by-step instructions
- Preheat the oven to 350°F. Grease a 9×13-inch baking pan with butter or nonstick spray.
- Press the biscuit dough evenly across the bottom of the greased pan, aiming for a uniform single-layer crust that reaches the edges.
- Heat a skillet over medium-high and add the breakfast sausage. Brown it, breaking it into small pieces until cooked through, about 6–8 minutes. Drain excess grease on paper towels and spread the sausage evenly over the biscuit crust.
- In a medium bowl, whisk together the eggs, milk, salt, and pepper until smooth and slightly frothy. Pour this egg mixture evenly over the sausage layer so it settles into gaps.
- Sprinkle 1 cup of the shredded cheese over the egg layer.
- Prepare the sausage gravy according to the packet instructions using 2 cups of water. Let the gravy cool just slightly so it’s warm but won’t curdle the eggs. Pour the gravy over the casserole in an even layer, then top with the remaining 1 cup cheese.
- Bake for 35 minutes, or until the eggs are set in the center and the top is golden. Remove from oven and let rest for 10 minutes before cutting into squares so the casserole firms up.
Short and actionable: press, brown, whisk, layer, pour, bake, rest.
Best ways to enjoy it
Serve warm from the pan in squares. Pair it with crisp fruit (apple slices or a citrus salad), lightly dressed greens, or simple roasted potatoes. For a brunch buffet, offer hot sauce, chopped scallions, and sour cream on the side so people can customize slices. For a dinner twist, serve with a crisp green salad and a cold beer — or try it as a portable brunch by wrapping slices in foil for picnics.
For a different comfort-casserole vibe, consider this diner-style cheeseburger French fry casserole if you want a lunch-friendly alternative.
Storage and reheating tips
- Refrigeration: Cool the casserole to room temperature (no more than two hours out) and store tightly covered for up to 3–4 days.
- Freezing: Cut into portions and wrap individually in plastic and foil or store in airtight containers. Freeze up to 2 months. Thaw in the fridge overnight before reheating.
- Reheating: Warm individual slices in a microwave (1–2 minutes, checking) or reheat in a 350°F oven for 12–18 minutes covered with foil, removing foil the last 5 minutes to refresh the top.
- Food safety: Reheat until the internal temperature reaches 165°F. Discard any leftovers kept at room temperature longer than 2 hours.
Helpful cooking tips
- Press biscuits thin: Flatten the refrigerated biscuit rounds slightly before pressing them together so the crust is even and bakes through.
- Drain sausage well: Excess grease seeps into the crust and can make it soggy. Pat the sausage on paper towels after browning.
- Slightly cool the gravy: Let the gravy rest a few minutes after making it. Pouring boiling gravy over raw eggs can cause them to set unevenly.
- Cheese placement: Putting cheese beneath and on top creates a melty middle and a slightly crisp top. For extra browning, broil for 1–2 minutes at the end — watch it closely.
- Make-ahead: Assemble the casserole the night before, cover, and refrigerate. Bake in the morning — you may need an extra 5–10 minutes of bake time if going in cold.
- For less runny slices: Use whole milk in the eggs and don’t overpour gravy; it should top the casserole but not drown it.
Creative twists
- Turkey or plant-based: Use turkey sausage or a plant-based crumbled sausage substitute to lower calories or keep it vegetarian.
- Veggie boost: Sauté onions, bell peppers, or mushrooms with the sausage for more flavor and texture.
- Homemade gravy: Make a simple sausage gravy with pan drippings, 3 tbsp flour, 2 cups milk, salt and pepper — skip the packet for control over seasoning.
- Spicy kick: Add 1/2 tsp cayenne or use chorizo-style sausage for heat.
- Biscuit swap: Use canned flaky biscuits for a lighter crust, or press refrigerated crescent dough for a different texture.
- Breakfast-for-dinner: Mix in cooked hash browns and swap half the cheese for pepper jack for a Tex‑Mex flair.
Common questions
Q: How long does total prep and cook time take?
A: Plan about 15–20 minutes for prep (pressing biscuits, browning sausage, whisking eggs) and 35 minutes to bake, plus a 10-minute rest — roughly an hour total.
Q: Can I use canned biscuits?
A: Yes. Canned biscuits are the standard called for here; press them together into a single layer. Flaky biscuits will bake up lighter but still work.
Q: Can I make the gravy from scratch instead of using the packet?
A: Absolutely. Use sausage drippings, a tablespoon or two of butter, 3 tablespoons flour cooked briefly, then whisk in 2 cups milk until thickened. Season to taste.
Q: Is there a way to keep the casserole from getting soggy?
A: Drain the browned sausage well and don’t overdo the gravy. Also allow the casserole to rest 10 minutes before cutting so it firms up.
Q: Can I assemble ahead and refrigerate?
A: Yes. Assemble, cover, and refrigerate overnight. Bake an extra 5–10 minutes if it goes into the oven cold.
Q: How should I reheat slices for a crowd?
A: Arrange slices on a sheet pan, tent with foil, and reheat at 350°F for 12–20 minutes until warmed through. For faster service, microwave portions for 1–2 minutes each.
