Ingredients
Sausage and Croissant
- 1 pound breakfast sausage
- 4 large croissants, torn into bite-size pieces
Egg Mixture
- 8 large eggs
- 1½ cups milk or half-and-half
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
Cheese and Garnish
- 2 cups shredded cheddar cheese
- 1 cup shredded mozzarella or Monterey Jack cheese
- ¼ cup green onions, sliced
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking.
- Cook Sausage: In a skillet over medium heat, cook the breakfast sausage until it is nicely browned and cooked through. Drain any excess grease to keep the casserole from being too oily.
- Layer Croissants: Evenly spread the torn croissant pieces across the bottom of the prepared baking dish, creating a fluffy base.
- Add Sausage: Sprinkle the cooked sausage evenly over the croissant pieces for a savory layer.
- Prepare Egg Mixture: In a large bowl, whisk together eggs, milk (or half-and-half), salt, black pepper, garlic powder, and onion powder until fully combined and smooth.
- Pour Egg Mixture: Pour the seasoned egg mixture evenly over the croissant and sausage layers in the baking dish.
- Add Cheese: Generously sprinkle the shredded cheddar and mozzarella (or Monterey Jack) cheeses evenly over the top of the casserole.
- Bake: Place the casserole in the preheated oven and bake uncovered for 35–40 minutes, or until the eggs are set completely and the top turns golden brown.
- Rest and Garnish: Remove casserole from oven and let it rest for 5 minutes before serving. Garnish with sliced green onions for a fresh, vibrant finish.
Notes
- Assemble the casserole the night before and refrigerate to save time in the morning.
- Substitute sausage with ham or bacon for different flavor variations.
- Add vegetables like bell peppers, spinach, or mushrooms to include more nutrients.
- Store leftovers in the refrigerator for up to 4 days.
- This casserole freezes well for up to 2 months—freeze before baking for best results.
