Easy Biscuits and Gravy Breakfast Casserole is a simple and hearty dish that brings together fluffy biscuits, rich sausage gravy, and eggs all baked into one comforting casserole. The biscuits soak up the creamy gravy, making every bite warm and satisfying. It’s a perfect way to start a weekend morning or feed a hungry crowd without spending too much time in the kitchen.
I love making this casserole when I want a cozy breakfast that feels homemade but doesn’t take forever to prepare. The best part is how the gravy and eggs meld together with the biscuits, creating a soft, flavorful dish that’s better than just biscuits and gravy on their own. Sometimes I sprinkle a bit of cheese on top before baking for a little extra gooey goodness.
One of my favorite ways to serve it is with a side of fresh fruit or a simple green salad to balance out all that savory comfort. This casserole also reheats really well, so it’s great for leftovers or planning ahead for brunch. If you’re looking for a breakfast that pleases both kids and adults alike, this is definitely a winner in my book!
Key Ingredients & Substitutions
Buttermilk Biscuits: Using refrigerated biscuits saves time and guarantees soft, flaky layers in your casserole. If you prefer, you can make your own biscuits or use canned flaky biscuits for a lighter texture.
Breakfast Sausage: Pork sausage adds authentic flavor, but you can swap in turkey sausage or plant-based sausage for a lighter or vegetarian option. Just make sure the sausage is well cooked before layering.
Sausage Gravy: Homemade gravy is simple with a roux and milk, but store-bought saves time. Choose a creamy gravy without lumps. If you want more flavor, stir in a pinch of black pepper or sage.
Eggs & Milk: Eggs bind everything together and add protein. Whole milk gives a creamy texture, but you may substitute with almond milk or oat milk if you like, though the texture may vary slightly.
Cheddar Cheese: Sharp cheddar melts well and adds a nice tang. Feel free to mix in other cheeses like mozzarella or Monterey Jack to change the flavor or make it milder for kids.
How Can You Get the Perfect Casserole Layers Without Soggy Biscuits?
The key is to balance soaking the biscuits with packed layers that hold their shape but stay soft.
- Cut biscuits into quarters so they absorb flavors but don’t become mushy.
- Cook and drain the sausage well to avoid excess grease that can make the casserole watery.
- Pour gravy evenly but avoid over-saturating the biscuits; just enough to coat.
- Whisk eggs and milk fully, then pour gently over all layers to fill gaps and hold everything together.
- Bake uncovered so the top crisps up slightly, adding nice texture.
- Let the casserole rest after baking so it firms up and slices nicely.
These simple steps help you get soft, tasty layers with a rich, satisfying bite every time!

Equipment You’ll Need
- 9×13-inch baking dish – perfect size for layering biscuits, gravy, and eggs evenly.
- Large skillet – you’ll cook and brown the sausage here; a nonstick one makes cleanup easy.
- Mixing bowl – for whisking eggs and milk smoothly before pouring into the casserole.
- Whisk – helps blend the eggs and milk without lumps for an even bake.
- Knife and cutting board – to cut the biscuits into quarters for layering.
- Measuring cups – to measure milk, cheese, and gravy accurately.
Flavor Variations & Add-Ins
- Swap pork sausage with spicy chorizo for a bold, smoky kick.
- Add sautéed peppers and onions for a bit of sweetness and extra texture.
- Stir in chopped cooked ham instead of sausage for a milder, smoky flavor.
- Top with pepper jack cheese for a creamy, spicy twist.

- 3 cups shredded cheddar cheese

How Much Time Will You Need?
This breakfast casserole takes about 15 minutes to prep and around 35-40 minutes to bake. Add a few minutes for resting before serving, making the total time roughly 55 minutes from start to finish.
Step-by-Step Instructions:
1. Preparing the Oven and Dish:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish so the casserole doesn’t stick.
2. Setting the Biscuit Base:
Cut each biscuit into quarters, then spread the pieces evenly in the bottom of the prepared dish. This creates a fluffy biscuit layer that will soak up the tasty gravy and sausage flavors.
3. Cooking the Sausage:
Use a large skillet over medium heat to cook the sausage. Break it apart as it cooks, making sure it’s well browned and fully done. Drain any excess fat to keep the casserole from getting greasy. Spread the cooked sausage evenly over the biscuit pieces.
4. Adding Gravy and Cheese:
Pour the sausage gravy evenly over the sausage layer, then sprinkle 2 cups of shredded cheddar cheese on top. This adds rich creaminess and cheesy flavor.
5. Mixing and Pouring the Eggs:
In a medium bowl, whisk together the eggs, milk, salt, and pepper until smooth. Pour this mixture evenly over all the layers in the baking dish.
6. Final Cheese Topping and Baking:
Sprinkle the remaining 1 cup of cheddar cheese on top. Bake the casserole for 35-40 minutes until the eggs are set and the cheese is melted and bubbly.
7. Resting and Serving:
Take the casserole out of the oven and let it rest for about 5 minutes. This helps it firm up, making it easier to cut and serving up warm, gooey comfort. Garnish with fresh parsley if you like, then enjoy!
Can I Use Frozen Biscuits Instead of Refrigerated?
Frozen biscuits can work, but make sure to thaw them completely before cutting and layering. This helps them bake evenly and absorb the gravy without turning soggy.
Is It Possible to Make This Casserole Ahead of Time?
Yes! Assemble the casserole the night before, cover it tightly with plastic wrap, and refrigerate. Bake it fresh in the morning, adding a few extra minutes to the baking time if needed.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave until warmed through, adding a splash of milk if it feels dry.
Can I Substitute the Sausage Gravy?
Absolutely! You can use homemade gravy, store-bought, or even a mushroom or vegetarian gravy if you prefer. Just make sure the gravy is thick enough to hold the layers together.
