This Biscuits and Gravy Breakfast Casserole is a warm and comforting dish perfect for breakfast or brunch! It features flaky biscuits soaked in creamy sausage gravy—yum!
Honestly, this casserole is so easy to make, it’s almost magical. Just layer the biscuits and gravy, bake, and enjoy! I love serving it to guests along with fresh fruit!
Key Ingredients & Substitutions
Refrigerated Biscuits: The cornerstone of this casserole! I love the convenience of store-bought biscuits. You can also use homemade ones if you have a favorite recipe or try crescent rolls for a different twist.
Breakfast Sausage: Pork sausage is traditional, but feel free to swap in turkey sausage or a plant-based alternative for a healthier or vegetarian option. Season it well to ensure great flavor!
Milk: Whole or 2% milk gives the gravy a nice creaminess. For a lighter touch, skim milk works too. You can also use unsweetened almond milk or oat milk for dairy-free versions.
Shredded Cheddar Cheese: Cheddar is a classic choice, but you can mix it up with Monterey Jack, Pepper Jack for some heat, or even a blend of your favorite cheeses. Just make sure it melts nicely!
How Do I Ensure My Gravy is Smooth and Not Lumpy?
Making the gravy is a crucial step, and keeping it smooth takes a little attention. Here’s how:
- Cook the sausage first, then sprinkle the flour evenly without clumping—this helps create a nice roux.
- When adding milk, pour it in slowly while stirring continuously. This helps to prevent lumps.
- Keep the heat medium; too high might clump the flour too quickly. Stir until the mixture thickens, which should take about 5-7 minutes.
- Taste and adjust the seasoning before pouring over the biscuits. A little extra salt or pepper can go a long way!

Biscuits And Gravy Breakfast Casserole
Ingredients You’ll Need:
For The Casserole:
- 1 can (16 oz) refrigerated biscuits (about 8 biscuits)
- 1 pound breakfast sausage (pork or your choice)
- 3 cups milk (whole or 2%)
- 1/3 cup all-purpose flour
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder (optional)
- 1/4 teaspoon onion powder (optional)
- 2 cups shredded cheddar cheese
- Fresh chopped chives or parsley for garnish (optional)
How Much Time Will You Need?
You’ll need about 15-20 minutes for preparation and about 25-30 minutes for baking. So, in total, you’ll spend around 45-50 minutes getting this delicious breakfast casserole ready to serve!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). It’s important to get that oven hot and ready for the casserole! Grease a 9×9-inch baking dish (or similar size) to prevent sticking.
2. Prepare the Biscuits:
Open the can of refrigerated biscuits and cut each one into quarters. Arrange the biscuit pieces evenly in the bottom of your greased baking dish, standing them up if you can; this will help them soak up that delicious gravy later!
3. Cook the Sausage:
In a large skillet over medium heat, cook the breakfast sausage until it’s browned and crumbly, which should take about 7-10 minutes. Be sure to drain any excess grease from the skillet for a healthier dish.
4. Make the Gravy:
Once the sausage is cooked, sprinkle the flour evenly over the sausage and stir until it’s well coated. Then, slowly pour in the milk while stirring continuously. This will help avoid any lumps. Cook and stir the gravy until it thickens, which should take around 5-7 minutes.
5. Season the Gravy:
Add the salt, black pepper, garlic powder, and onion powder to your gravy. Stir well to combine. Don’t forget to taste and adjust the seasonings to your liking!
6. Assemble the Casserole:
Now, pour the hot sausage gravy evenly over the biscuits in the baking dish. Make sure every bit of biscuit gets that tasty gravy!
7. Add Cheese:
Sprinkle the shredded cheddar cheese evenly over the top of the gravy-soaked biscuits. Cheese makes everything better, doesn’t it?
8. Bake:
Place your casserole uncovered in the oven and bake for 25-30 minutes. It’s done when the biscuits are cooked through and the cheese is melted and bubbly—so enticing!
9. Garnish and Serve:
Once you take it out of the oven, let it cool for a few minutes. If you’d like, sprinkle some freshly chopped chives or parsley on top for a pop of color. Now, serve warm and enjoy your hearty biscuits and gravy breakfast casserole!
Can I Use Frozen Biscuits Instead of Refrigerated Biscuits?
Absolutely! Just make sure to thaw the frozen biscuits before cutting them into quarters. You can do this by leaving them in the fridge overnight or microwaving them for a few seconds until soft.
How Can I Make This Casserole Vegetarian?
To make a vegetarian version, simply substitute the breakfast sausage with a plant-based sausage or mushrooms. You can also add some sautéed vegetables like spinach or bell peppers for extra flavor and nutrients.
Can I Prepare This Casserole Ahead of Time?
Yes! You can assemble the casserole the night before and refrigerate it overnight. Just bake it in the morning for a delicious breakfast. You may need to add an extra 5-10 minutes to the baking time if it’s coming straight from the fridge.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm it up in the oven at 350°F (175°C) for about 15-20 minutes or until heated through. You can also use the microwave for quicker reheating.
