Biscuits and Gravy Breakfast Casserole

The part that makes or breaks this casserole is the gravy. If it goes into the baking dish loose like regular sausage gravy, the biscuits underneath can turn pasty by the time the eggs finish setting. I make the gravy a little thicker here, then leave a few biscuit tops exposed so they brown on top instead of steaming completely under the sauce.

Done right, this cuts like a soft breakfast bake instead of collapsing when you scoop it. You get tender biscuit pieces underneath, browned edges on top, peppery sausage gravy that still has some body, and pockets of melted cheddar through the middle.

Why This Biscuits and Gravy Breakfast Casserole Works

• The gravy is thick enough to stay creamy through baking instead of soaking the biscuit layer.
• The eggs give the casserole structure, so it slices cleanly after a short rest.
• It holds up better than most make-ahead breakfast bakes.
• You still get contrast: browned biscuit peaks on top, a soft center, and melted cheddar throughout.

Ingredients for Biscuits and Gravy Casserole with Eggs

• 1 can refrigerated biscuits (460g)
• 1 pound breakfast sausage (455g)
• 1/4 cup all-purpose flour (30g)
• 2 1/2 cups whole milk (600g)
• 6 large eggs (300g)
• 1 cup shredded cheddar cheese (115g)
• 1/2 teaspoon 👉garlic powder
• 1/2 teaspoon 👉onion powder
• 1/2 teaspoon black pepper
• 1/4 teaspoon salt
• nonstick cooking spray

Best sausage to use for the gravy

Regular breakfast sausage works best here because it usually renders enough fat to carry the flour and build the gravy. Mild or hot both work.

If your sausage is very lean and the skillet looks dry after browning, add 1 tablespoon butter before adding the flour.

Biscuit, cheese, and milk notes

Use standard refrigerated biscuits rather than flaky layered ones if possible. The regular style bakes more evenly once cut up.

Whole milk gives the gravy better body. Lower-fat milk works, but the sauce stays looser.

Sharp cheddar is the better choice here because the gravy and eggs mute milder cheese pretty quickly.

How to Make Biscuits and Gravy Breakfast Casserole

Brown the sausage and build flavor

1. Preheat the oven to 350°F. Grease a 9×13-inch baking dish.
2. Cut the biscuits into even quarters. Scatter them in the baking dish with a little space between pieces. Don’t press them into a tight layer or the bottom can stay heavy and underbaked.
3. In a large skillet over medium heat, cook the sausage for 6 to 8 minutes, breaking it up as it browns, until there is no pink left and some pieces have deep brown edges, not just a gray surface. If there is excessive grease, spoon off a little, but leave enough to coat the pan. If the pan looks dry, add 1 tablespoon butter before moving on.

Make a thick sausage gravy for casserole

1. Sprinkle the flour over the sausage and stir for 1 to 2 minutes until the flour looks fully absorbed and lightly foamy. You shouldn’t see dry white pockets.
2. Pour in the milk gradually, whisking as you go. Bring the mixture to a gentle simmer and cook for 4 to 5 minutes, stirring often, until the gravy is noticeably thicker than standard breakfast gravy. It should leave a trail when stirred and mound lightly on a spoon. If it still looks loose, simmer it another minute or two.
3. Stir in the garlic powder, onion powder, black pepper, and salt. Remove from the heat and let the gravy cool for 2 to 3 minutes so the eggs don’t start setting on contact.

Layer the biscuits so they bake through

1. In a medium bowl, whisk the eggs until fully blended. Stir the eggs into the slightly cooled gravy until the mixture is even.
2. Pour the gravy mixture over the biscuit pieces. Use a spoon to nudge a few biscuit corners and tops back up so some pieces stay exposed. That helps the top brown instead of steam.
3. Sprinkle the cheddar evenly over the casserole.

Bake until the eggs are just set

1. Bake for 30 to 35 minutes, until the top is golden, the exposed biscuit pieces feel set rather than doughy, and the center no longer looks glossy when the pan is gently shaken. A knife inserted near the middle should come out moist, but not with raw egg on it.
2. If the top browns too quickly, tent it loosely with foil for the last few minutes.
3. Rest the casserole for 10 minutes before slicing. That short rest helps the center firm up and the slices hold together better.

My Best Tips for the Perfect Biscuits and Gravy Casserole

Keep the gravy thicker than usual

It should drag slightly behind the spoon instead of flowing back right away. Once it bakes with the eggs, it loosens a little again.

Leave some biscuit tops exposed

That gives you contrast: soft pieces underneath and browned pieces on top.

Do not leave too much grease in the skillet

You need enough fat to make the gravy, but not so much that the finished casserole turns oily.

Biscuits and Gravy Breakfast Casserole Variations

Hash Brown Biscuits and Gravy Breakfast Casserole

Add about 2 cups thawed hash browns (240g), squeezed dry in a towel, to the baking dish before the biscuits, or mix them loosely with the biscuit pieces.

Keep the layer thin. If the potatoes go in wet, they release moisture and soften the whole casserole. This version bakes up a little sturdier and more filling.

No-Egg Option for Biscuits and Gravy Casserole

For a no-egg version, leave out the eggs and reduce the milk to 2 cups (480g). Make the gravy slightly thicker than usual, then pour it over the biscuit pieces and top with cheese. Bake until the biscuits are cooked through and the top is browned, about 25 to 30 minutes.

This version won’t slice as neatly. It eats more like a baked pan of biscuits and gravy than a custard-set casserole.

Make-Ahead, Storage, and Reheating

Can you assemble it the night before?

Yes, but for the best biscuit texture, I prefer a partial make-ahead approach: cook the sausage gravy, cool it, and refrigerate it separately.

In the morning, cut the biscuits, whisk in the eggs, assemble, and bake. If you fully assemble it the night before, the biscuits soften more and the bottom layer gets denser.

How to freeze and reheat without sogginess

Freeze it after baking, not before. Let the baked casserole cool completely, wrap tightly, and freeze for up to 2 months.

Reheat covered at 325°F until hot in the center, then uncover for the last few minutes to dry the surface slightly. Individual slices reheat fine in the microwave, but the biscuit edges stay better in the oven.

Biscuits and Gravy Breakfast Casserole FAQ

Why did my biscuits and gravy casserole turn out soggy?

Usually the gravy was too thin, the biscuits were packed too tightly, or the casserole came out before the center finished setting. It should not look liquid in the middle when you gently shake the pan.

How thick should the sausage gravy be before baking?

Thick enough to coat the sausage heavily and leave clear lines when you stir it. If it pours like regular table gravy, it is too thin for this casserole.

Can I use frozen hash browns?

Yes, but thaw them first and squeeze them dry. Wet potatoes release moisture and soften the biscuit layer.

Can I make this without eggs?

Yes. Use less milk and a thicker gravy, then expect a softer, scoopable bake instead of neat slices.
