Ingredients
Scale
Base
- 1 (16 oz) can refrigerated biscuit dough, cut into quarters
Protein
- 1/2 pound breakfast sausage or 6 strips bacon, cooked and crumbled
- 6 large eggs
Dairy
- 1 1/2 cups shredded sharp cheddar cheese
- 1/2 cup milk
Vegetables & Seasoning
- 1/4 cup chopped green onions
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
Other
- Nonstick cooking spray
Instructions
- Preheat and Prepare Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish evenly with nonstick cooking spray to prevent sticking.
- Arrange Biscuit Pieces: Cut the refrigerated biscuit dough into quarters, then place the pieces evenly across the bottom of the prepared baking dish, creating a base layer.
- Cook Meat: In a skillet over medium heat, cook the breakfast sausage until fully browned and crumbly, or cook the bacon strips until crispy. Drain any excess grease from the cooked meat, then sprinkle it evenly over the biscuit pieces in the dish.
- Add Cheese and Onions: Sprinkle the shredded sharp cheddar cheese over the meat layer, then add the chopped green onions evenly on top, distributing the flavors throughout.
- Prepare Egg Mixture: In a medium mixing bowl, whisk together the 6 large eggs, 1/2 cup milk, garlic powder, salt, and black pepper until well combined and slightly frothy.
- Pour Egg Mixture: Carefully pour the egg mixture evenly over all the ingredients in the baking dish, ensuring it seeps around and between the biscuit pieces, meat, cheese, and onions.
- Bake: Place the baking dish in the preheated oven and bake for 35 to 40 minutes. The casserole is done when the eggs are fully set (no longer jiggly) and the top is golden brown.
- Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes before slicing into squares. Serve warm for a satisfying breakfast or brunch.
Notes
- This casserole can be prepared the night before and baked fresh in the morning for convenient meal prep.
- For extra nutrition and flavor, add diced bell peppers, mushrooms, or spinach with the cheese and green onions.
- You can substitute the sharp cheddar cheese with pepper jack or Swiss cheese to vary the flavor profile.
- If using bacon, ensure it’s chopped finely so it distributes evenly in the casserole.
- Use nonstick cooking spray liberally to ensure easy cleanup and removal of the casserole from the dish.
