📝 Ingredients
For the Biscuit Base
- 1 can refrigerated biscuits of your choice
- Nonstick cooking spray
For the Breakfast Filling
- 1 pound breakfast sausage
- 8 large eggs
- ½ cup milk
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
For the Cheese
- 1½ to 2 cups shredded cheddar cheese
Optional Add-Ins
You can make this casserole your own by adding:
- ½ cup diced onion
- ½ cup diced bell pepper
- ½ cup sliced mushrooms
- ½ cup cooked bacon, chopped
- ½ cup diced ham
- ½ cup cooked hash browns
- ¼ teaspoon paprika
- Chopped green onions for garnish
👩🍳 Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly spray a 9×13-inch baking dish with nonstick cooking spray. Make sure the bottom and sides are well coated so the casserole is easier to serve.
Step 2: Prepare the Sausage
Place a large skillet over medium heat.
Add the breakfast sausage and cook until completely browned and no longer pink. Break it apart with a spoon as it cooks.
If using onions or bell peppers, add them to the skillet and cook until softened.
Drain any excess grease from the sausage and set it aside.
Step 3: Create the Biscuit Layer
Open your refrigerated biscuits and arrange them across the bottom of the prepared baking dish.
Depending on the size of your biscuits, you can place them whole or gently press them slightly flat so they cover more of the bottom.
The biscuits will bake into a delicious, soft and buttery base for the casserole.
Step 4: Add the Sausage
Evenly sprinkle the cooked sausage over the biscuit layer.
Try to spread it all the way across the pan so every serving receives plenty of savory sausage.
If you are adding cooked bacon, ham, or hash browns, this is the time to add them as well.
Step 5: Prepare the Egg Mixture
In a large bowl, whisk together:
- 8 eggs
- ½ cup milk
- Salt
- Black pepper
- Garlic powder
- Onion powder
Whisk until the eggs are smooth and well combined.
For extra flavor, you can add a little paprika or a pinch of your favorite seasoning blend.
Step 6: Pour Over the Casserole
Slowly pour the seasoned egg mixture evenly over the sausage and biscuit layers.
Allow the egg mixture to flow into the spaces between the biscuits.
Step 7: Add the Cheese
Sprinkle the shredded cheddar cheese evenly over the top.
For an extra cheesy casserole, you can use a combination of:
- Cheddar
- Monterey Jack
- Colby Jack
- Pepper Jack
A little extra cheese on top creates a beautiful golden, bubbling finish.
🔥 Baking Method
Place the casserole in the preheated 350°F oven.
Bake for approximately 35–45 minutes, or until:
- The eggs are completely set.
- The biscuits are cooked through.
- The cheese is melted and golden.
- The center no longer jiggles when gently shaken.
If the top begins to brown too quickly, loosely cover the casserole with aluminum foil for the remaining baking time.
Allow the casserole to rest for 5–10 minutes before slicing. This helps the layers settle and makes the casserole easier to serve.
🍽️ Serving Suggestions
Slice the casserole into squares and serve warm.
It is delicious with:
- Fresh fruit
- Orange juice
- Coffee
- Fresh berries
- Sliced tomatoes
- Fresh avocado
- A spoonful of salsa
- Hot sauce
- Country gravy
For a complete breakfast spread, serve it with fresh fruit and a warm cup of coffee.

❄️ Make-Ahead Method
This casserole is perfect for preparing ahead of time.
Assemble the casserole, cover it tightly, and refrigerate it overnight.
The next morning, remove it from the refrigerator while the oven preheats. Bake as directed, adding a few extra minutes if necessary because the casserole starts cold.
This makes it especially convenient for:

- Thanksgiving brunch
- Family gatherings
- Weekend guests
- Busy mornings
🧊 Storage
Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
To reheat, place a serving in the microwave and heat until warmed through.
You can also reheat the casserole in the oven at 325°F until hot.
❄️ Freezing Instructions
Allow the baked casserole to cool completely.
Cut it into individual portions and wrap each portion tightly in plastic wrap and foil, or place the pieces in freezer-safe containers.
Freeze for up to 2–3 months.
Thaw overnight in the refrigerator and reheat until hot.
