Easy Biscuits and Gravy Breakfast Casserole is a hearty, comforting breakfast that combines flaky biscuits, creamy sausage gravy, and eggs baked all together in one dish. It’s like a cozy hug on a plate, with the warm and rich flavors you expect from a classic Southern breakfast but made so much simpler to prepare. The biscuits soak up all the delicious gravy and eggs, creating a soft, flavorful texture that everyone will love.
I love making this casserole on weekend mornings when there’s no rush and the whole family wants something filling and tasty. What I really appreciate is how you can put it together the night before, pop it in the fridge, and then bake it fresh in the morning without any stress. Plus, it’s a great way to feed a crowd without standing over the stove for hours. The sausage gravy is perfectly seasoned, and the biscuits give just the right bit of buttery crunch.
My favorite way to serve this casserole is with a side of fresh fruit or some crispy bacon, and a hot cup of coffee nearby. It’s definitely a crowd-pleaser and has become my go-to for holidays or lazy weekend brunches. Whenever I make it, people ask for the recipe because it feels like such a special, homemade treat but is actually so simple. This one always brings smiles and full bellies!
Key Ingredients & Substitutions
Biscuit Dough: Refrigerated biscuit dough is a real time-saver with its flaky texture. If you can’t find it, use homemade biscuits or even canned crescent roll dough as an easy swap.
Breakfast Sausage: Traditional pork sausage adds good flavor here. For a lighter version, try turkey sausage or plant-based sausage to suit your diet.
Milk: Whole milk makes a creamy gravy, but 2% or even oat milk works fine if you prefer a dairy-free option.
Cheese: Sharp cheddar is my favorite for that melty, tangy kick. Monterey Jack or Colby cheese are good alternatives if you want something milder.
Eggs: Eggs help bind the casserole and add richness. Make sure to whisk them just until combined for a fluffy texture.
How Do You Make the Best Creamy Sausage Gravy?
Making sausage gravy is key for this dish. Here’s how to get it just right:
- Cook the sausage thoroughly, breaking it into small crumbles so it cooks evenly.
- Sprinkle in the flour while the sausage is hot. Stir well to coat all meat. Cook 1-2 mins to get rid of raw flour taste.
- Slowly pour in milk while whisking constantly. This keeps lumps from forming and thickens gravy evenly.
- Keep stirring on medium heat until gravy thickens. Don’t rush—it might take 4-6 minutes.
- Season with salt, pepper, and optional spices like garlic and onion powder to boost flavor.
Patience is key for smooth gravy. This step makes your dish extra comforting and flavorful!
Equipment You’ll Need
- 9-inch round or 8×8-inch baking dish – perfect size for baking the casserole evenly.
- Large skillet – great for cooking the sausage and making the gravy in one pan.
- Whisk – helps you mix the gravy smoothly without lumps.
- Mixing bowl – for whisking the eggs before pouring them over the biscuits.
- Measuring cups and spoons – to get your ingredients just right.
Flavor Variations & Add-Ins
- Swap pork sausage for spicy chorizo to add a smoky, bold flavor that wakes up the dish.
- Stir in sautéed mushrooms or bell peppers before layering for extra veggies and earthiness.
- Use pepper jack cheese instead of cheddar for a little spicy kick.
- Add cooked, crumbled bacon for smoky crunch that pairs perfectly with the creamy gravy.

Ingredients You’ll Need:
For The Casserole:
- 1 tube (16 oz) refrigerated biscuit dough (like flaky biscuits)
- 1 lb breakfast sausage (pork or your choice)
- 3 tablespoons all-purpose flour
- 2 ½ cups milk (whole or 2%)
- 1 teaspoon salt (or to taste)
- ½ teaspoon black pepper (freshly ground preferred)
- 1 teaspoon garlic powder (optional)
- ½ teaspoon onion powder (optional)
- 1 ½ cups shredded sharp cheddar cheese
- 6 large eggs
- ¼ cup chopped fresh parsley or chives (for garnish, optional)

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and 30-40 minutes to bake, so plan for a total of around 45-55 minutes from start to finish. It’s quick enough for a hearty weekend breakfast or brunch without much fuss!
Step-by-Step Instructions:
1. Prepare for Baking:
Preheat your oven to 350°F (175°C). Grease a 9-inch round or 8×8-inch square baking dish lightly with butter or non-stick spray so nothing sticks.
2. Arrange the Biscuits:
Separate the biscuit dough into individual biscuits. Place them in a single layer in the greased baking dish. They should be close but not overlapping too much.
3. Cook the Sausage:
In a large skillet over medium heat, cook the breakfast sausage, breaking it apart with a spoon until browned and cooked all the way through (about 6-8 minutes). Drain any excess grease before moving on.
4. Make the Sausage Gravy:
Sprinkle the flour evenly over the cooked sausage, stirring well to coat the meat. Cook this mixture for 1-2 minutes to remove the raw flour taste. Slowly whisk in the milk, stirring continuously until the gravy thickens (about 4-6 minutes). Season with salt, black pepper, garlic powder, and onion powder if using. Then, remove the gravy from heat.
5. Add Cheese and Eggs:
Sprinkle half of the shredded cheddar evenly over the biscuits in the baking dish. In a separate bowl, lightly whisk the eggs and then pour the eggs over the cheese-covered biscuits.
6. Layer on Gravy and Cheese:
Carefully spoon the thick sausage gravy evenly over the eggs. Then top with the remaining shredded cheddar cheese.
7. Bake and Serve:
Bake the casserole for 30-40 minutes, or until the eggs are fully set and the biscuits are cooked through and golden on top. Remove from oven, sprinkle with fresh parsley or chives if you like, let cool a little, then slice and serve.
Can I Use Frozen Biscuits Instead of Refrigerated Dough?
Yes, you can! Just thaw the frozen biscuits completely in the refrigerator before assembling the casserole to ensure even cooking.
Can I Prepare This Casserole the Night Before?
Absolutely! Assemble the casserole as directed, cover it tightly with foil or plastic wrap, and refrigerate overnight. Bake it fresh in the morning, adding a few extra minutes to the baking time if needed.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or oven until warmed through.
Can I Make This Recipe Dairy-Free or Low-Fat?
Yes! Use dairy-free milk alternatives like almond or oat milk and substitute the cheese with a dairy-free variety or omit it. For a lower-fat option, use lean turkey sausage and reduce the amount of cheese.
