This Easy Biscuits and Gravy Breakfast Casserole is the perfect way to kick off any morning with a warm, hearty meal. It combines fluffy biscuits, creamy sausage gravy, and eggs baked together until golden and bubbling. The rich sausage flavor mixed with the soft biscuits makes every bite comforting and satisfying.
I love making this casserole when I have a bunch of family or friends over because it’s super simple to prepare but feels like a special treat. The best part is how the biscuits soak up all the gravy and egg, turning soft and flavorful without getting soggy. I usually throw it together the night before and just pop it in the oven in the morning—easy and no fuss.
Serving it up with a little fresh fruit or a simple green salad balances the richness and makes for a complete meal. It’s one of those dishes that everyone keeps asking for again and again, whether it’s a lazy weekend breakfast or a holiday brunch. I always find it brings people together with its cozy, homey vibes.
Key Ingredients & Substitutions
Biscuit dough: Using canned biscuit dough makes this recipe quick and easy. If you prefer, you can use homemade biscuits or even cut-up store-bought biscuits. For a healthier twist, whole wheat biscuits work well too.
Breakfast sausage: Classic pork sausage is perfect here for its flavor and fat content, which helps the gravy stay rich. Turkey sausage or plant-based sausage can be good alternatives for a lighter or vegetarian version.
Cheddar cheese: Sharp cheddar adds a nice tang and melts well in this casserole. Feel free to mix cheeses like Monterey Jack or mozzarella for a different texture and taste.
Milk and flour (for gravy): Milk creates the creamy base of the gravy, and flour thickens it. You can substitute with non-dairy milk and use cornstarch or a gluten-free flour blend to make the dish dairy-free or gluten-free if needed.
Eggs: Eggs bind the casserole and give it that custardy texture. Make sure to whisk them well so they distribute evenly.
How Do You Make Sausage Gravy Thick and Creamy?
Making the perfect sausage gravy is all about the roux and slow cooking. Here’s what works for me:
- First, cook sausage fully and drain excess grease to avoid a greasy gravy.
- Use equal parts butter and flour to make your roux, cooking it until it’s golden but not browned. This step cooks out the raw flour taste and starts thickening.
- Gradually add milk while whisking to avoid lumps, and keep stirring until it thickens—this usually takes 4-5 minutes over medium heat.
- Season with salt, pepper, and a pinch of garlic powder for extra flavor.
Taking your time and stirring constantly during this step is key. If the gravy gets too thick, just add a splash of milk to loosen it up before pouring over the casserole.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for layering biscuits, gravy, and eggs evenly.
- Large skillet – great for browning sausage thoroughly without crowding.
- Medium saucepan – where you’ll make the creamy sausage gravy smoothly.
- Whisk – essential to keep your gravy lump-free and eggs well beaten.
- Mixing bowl – handy for beating eggs before pouring over the casserole.
- Knife and cutting board – for slicing biscuits into bite-sized pieces.
Flavor Variations & Add-Ins
- Swap breakfast sausage with spicy chorizo for a bolder, smoky flavor that wakes up your taste buds.
- Stir in sautéed bell peppers or mushrooms for extra veggies and a bit of sweetness or earthiness.
- Try pepper jack cheese instead of cheddar for a creamy texture with a little heat.
- Add cooked bacon bits on top before baking for a crispy, smoky crunch that contrasts nicely with soft biscuits.
Easy Biscuits and Gravy Breakfast Casserole
Ingredients You’ll Need:
Main Ingredients:
- 1 can (16 oz) refrigerated biscuits (such as buttermilk biscuits)
- 1 pound breakfast sausage
- 3 cups shredded cheddar cheese, divided
- 2 cups milk
- ¼ cup all-purpose flour
- 6 large eggs

How Much Time Will You Need?
This casserole takes about 15 minutes to prepare and 35–40 minutes to bake, for a total of roughly 50 minutes before enjoying a warm, delicious breakfast with your family or friends.
Step-by-Step Instructions:
1. Prepare Your Baking Dish and Biscuits:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray. Cut each biscuit into quarters or bite-sized pieces, then evenly spread them across the bottom of the prepared dish.
2. Cook the Sausage:
In a large skillet over medium heat, cook the breakfast sausage until browned and fully cooked, breaking it into crumbles as it cooks. Drain any excess grease carefully.
3. Layer Sausage and Cheese:
Sprinkle half of the cooked sausage evenly over the biscuit pieces. Then add 1 cup of the shredded cheddar cheese evenly over the sausage layer.
4. Make Sausage Gravy:
In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook it for 1–2 minutes, whisking constantly until lightly golden. Gradually whisk in the milk, stirring continuously until the mixture thickens to a creamy gravy consistency, about 4–5 minutes. Season with salt, pepper, and garlic powder if using.
5. Assemble the Casserole:
Pour the warm sausage gravy evenly over the biscuits, sausage, and cheese layers in the baking dish. In a separate bowl, whisk the eggs until smooth, then pour them evenly over the casserole.
6. Add Remaining Sausage and Cheese, Then Bake:
Top the casserole with the remaining cooked sausage and shredded cheddar cheese. Place in the oven and bake for 35–40 minutes, or until the eggs are set and the top is golden brown and bubbly.
7. Serve:
Allow the casserole to cool for a few minutes before slicing. Garnish with fresh chopped parsley if you like, and serve warm for a hearty and comforting breakfast.
Can I Use Frozen Biscuits Instead of Refrigerated?
Yes, you can use frozen biscuits, but make sure they are fully thawed before cutting and assembling the casserole. Thaw them in the fridge overnight or at room temperature for a couple of hours to ensure even baking.
Can I Make This Breakfast Casserole Ahead of Time?
Absolutely! Prepare the entire casserole the night before, cover it tightly with foil or plastic wrap, and refrigerate. In the morning, bake it for about 40-50 minutes (adding extra baking time since it will be cold) until fully set and bubbly.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or oven until warmed through. For best texture, reheat gently to avoid drying out the eggs and biscuits.
Can I Add Vegetables to This Casserole?
Definitely! Sautéed onions, bell peppers, mushrooms, or spinach make great additions. Just cook them beforehand to remove excess moisture and mix them with the sausage or layer them before adding the gravy and eggs.
