This recipe is rooted in Southern comfort — combining the buttery layers of biscuits, savory sausage, fluffy eggs, and melty cheese. Whether you’re feeding a crowd, prepping for a holiday morning, or just craving a hearty start to the day, this casserole has you covered.
What Is Biscuit Breakfast Casserole?
A Biscuit Breakfast Casserole is a layered, baked breakfast dish made with biscuit dough (store-bought or homemade), combined with a savory mix of breakfast staples like eggs, cheese, sausage, and veggies. It’s baked until golden and set, creating a bubbly, satisfying dish that’s great for sharing.
This is a brunch favorite across the U.S., often served on holidays like Christmas morning, Easter, or for weekend get-togethers. It’s flexible, forgiving, and incredibly delicious.
Ingredients
This recipe serves 8 generous portions.
Main Ingredients:
- 1 can (16 oz) refrigerated biscuit dough (or homemade biscuits, cut into pieces)
- 1 pound breakfast sausage (pork or turkey)
- 1/2 cup yellow onion, diced
- 1/2 cup red bell pepper, diced
- 1 cup shredded cheddar cheese
- 6 large eggs
- 1/2 cup milk (whole or 2%)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- Optional: chopped chives, parsley, or hot sauce for topping
Time Breakdown
- Prep time: 15 minutes
- Cook time: 35–40 minutes
- Total time: 50–55 minutes
Step-by-Step Instructions
Step 1: Preheat Oven & Grease the Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray.
Step 2: Cook the Sausage
In a large skillet, cook sausage over medium heat until browned. Use a spatula to break it into crumbles. Add the onions and bell peppers and sauté until tender (about 5 minutes). Drain excess grease.
Step 3: Prepare the Biscuits
Cut the biscuit dough into quarters. Spread the biscuit pieces evenly in the bottom of your prepared dish.
Step 4: Layer the Good Stuff
Spoon the sausage and veggie mixture over the biscuit pieces. Sprinkle cheese evenly across the top.
Step 5: Mix & Pour the Egg Mixture
In a bowl, whisk together the eggs, milk, salt, and pepper. Pour evenly over the sausage, biscuits, and cheese.
Step 6: Bake
Bake uncovered for 35–40 minutes, or until the center is set and the biscuits are puffed and golden. A knife inserted in the middle should come out clean.
Step 7: Rest & Serve
Let cool for 5–10 minutes before slicing. Top with fresh herbs or a drizzle of hot sauce if desired.
