How to Make Southern-Style Sausage, Biscuit & Gravy Breakfast Casserole Recipe

Step 1: Cook the Sausage

Start by browning your breakfast sausage over medium heat in a skillet. The sizzling aroma is enough to get you excited already! Cook until it’s nicely browned and crumbly, then drain off any excess grease to keep the casserole from getting greasy—it’s all about that perfect balance.

Step 2: Prepare the Biscuit Layer

While the sausage cooks, preheat your oven to 350°F (180°C) and grease a 9×13 baking dish. Then, scatter those biscuit pieces evenly across the dish’s bottom. The biscuits act as the soft, fluffy foundation that will soak up all the delicious flavors coming their way.

Step 3: Layer Sausage and Cheese

Next, sprinkle the browned sausage over the biscuit pieces, making sure it’s well distributed. Then, pile on the shredded cheddar cheese, which will melt and bubble into every nook of the casserole, creating those luscious cheesy pockets everyone loves.

Step 4: Make the Country Gravy

Now for the magic—using the same skillet, melt the butter over medium heat. Whisk in the flour and cook for 1 to 2 minutes to create a roux, the base for your gravy. Slowly add the milk while whisking constantly so no lumps form. Add the garlic powder, onion powder, salt, and pepper, and stir until the mixture thickens into that creamy country gravy everyone dreams about. Remove from heat once thickened.

Step 5: Assemble and Add Egg Mixture

Pour the gravy evenly over the sausage and biscuit layers, making sure it spreads to every corner. In a bowl, whisk together eggs, milk, salt, and pepper gently. Pour this egg mixture over the entire casserole, letting it settle and soak in the savory layers beneath.

Step 6: Bake to Perfection

Pop your assembled casserole into the oven and bake for 40 to 45 minutes until the top is golden and the egg mixture is set. The smell wafting through your kitchen will be irresistible. Let it rest for 10 minutes before serving, which helps everything firm up for perfect slicing.

Garnishes

To elevate this hearty dish, sprinkle fresh chopped parsley or green onions on top just before serving. A little color and freshness are the perfect counterpoint to the rich, creamy casserole. For those who love a spicy kick, a dash of hot sauce or crushed red pepper flakes works wonders.

Side Dishes

Pair this casserole with simple sides like fresh fruit salad or roasted veggies to add brightness and balance. Crispy bacon or a side of grits also complement the Southern vibe perfectly, making your breakfast feast feel complete and well-rounded.

Creative Ways to Present

If you want to impress guests or just switch things up, serve the casserole in individual ramekins for a personal touch. Alternatively, layering the casserole the night before and baking it fresh in the morning adds an effortless wow factor while giving you more time to relax and enjoy the company.

Make Ahead and Storage

Storing Leftovers

Wrap any leftovers tightly with plastic wrap or store in an airtight container and place in the refrigerator. The casserole will keep well for 3 to 4 days, giving you easy options for reheated breakfasts or lunches during busy weekdays.

Freezing

This casserole freezes beautifully. Assemble it fully, cover it tightly with foil, and freeze for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge before baking as directed for a fresh-from-the-oven experience.

Reheating

Reheat individual portions in the microwave for 1 to 2 minutes or warm the whole dish covered in a 350°F oven until heated through. Adding a little splash of milk before reheating helps keep it moist and creamy.

FAQs

Can I use homemade biscuits instead of canned?

Absolutely! Homemade biscuits lend an even richer texture and can make the dish feel extra special, but canned biscuits are a reliable shortcut that still tastes fantastic.

Is there a vegetarian version of this casserole?

Yes! You can substitute the sausage with plant-based sausage or even sautéed mushrooms and bell peppers for a vegetarian-friendly twist that still tastes hearty and satisfying.

Can I prepare this casserole the night before?

Definitely! Assemble the entire casserole the evening prior, keep it covered in the fridge, and bake fresh in the morning. This makes busy mornings so much easier without sacrificing flavor.

What can I add to the gravy to make it spicier?

Add a pinch of cayenne pepper, a dash of hot sauce, or some crushed red pepper flakes to the gravy when cooking to bring a lively Southern heat that wakes up your taste buds.

How do I know when the casserole is done baking?

You’ll want the top to be golden brown and the egg layer fully set without being jiggly. A toothpick or knife inserted in the center should come out mostly clean, signaling it’s ready to enjoy.
