Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
• 16.3 ounces refrigerated biscuits (about 8 biscuits)
• 1 pound breakfast sausage
• 8 large eggs
• 1 1/4 cups whole milk
• 1 teaspoon salt
• 1/4 teaspoon garlic powder
• 1/4 teaspoon black pepper
• 1 cup shredded cheddar cheese
• 1 cup shredded Monterey Jack cheese
Directions
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.
Open the can of biscuits, separate them, and cut each biscuit into quarters. Arrange the pieces evenly in the bottom of the prepared baking dish.
In a medium skillet over medium heat, cook the breakfast sausage until browned and fully cooked, breaking it into small crumbles. Drain any excess grease. Spread the cooked sausage evenly over the biscuit pieces.
In a large mixing bowl, whisk together the eggs, milk, salt, garlic powder, and black pepper until fully combined. Pour the egg mixture evenly over the sausage and biscuit layers.
Sprinkle the cheddar and Monterey Jack cheeses evenly over the top of the casserole.
Bake for 35–40 minutes, or until the eggs are fully set and the top is golden brown. Test by inserting a knife into the center—it should come out clean.
Let the casserole cool for 5–10 minutes before slicing and serving.
Add sautéed vegetables like bell peppers, onions, or spinach for extra flavor and nutrients.
Substitute turkey sausage or chicken sausage if preferred.
Swap cheeses for mozzarella, Swiss, or pepper jack for a different flavor profile.
Add diced jalapeños or a pinch of red pepper flakes for a spicy version.
Mix in fresh herbs such as parsley, chives, or thyme for a fresh taste.
Storage/Reheating
Store leftovers in an airtight container in the refrigerator for 3–4 days. Reheat in the oven at 350°F (175°C) for 15–20 minutes, covered with foil, or microwave individual slices until hot. For meal prep, assemble the casserole the night before and bake it the next morning.
