  • Total Time: 50 minutes
  • Yield: 6 servings

Ingredients

Base

  • 4 large croissants, torn into pieces

Sausage

  • 1 pound breakfast sausage

Egg Mixture

  • 6 large eggs
  • 1 1/2 cups milk
  • 1/2 teaspoon garlic powder
  • Salt and black pepper to taste

Cheese

  • 1 cup shredded cheddar cheese
  • 1/2 cup shredded mozzarella cheese

Garnish (Optional)

  • Chopped parsley

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to ensure it reaches the correct temperature for even baking before assembling the casserole.
  2. Cook Sausage: In a skillet over medium heat, cook the breakfast sausage until it is well browned and cooked through. Drain excess grease to avoid a greasy casserole.
  3. Prepare Baking Dish: Grease a baking dish lightly to prevent sticking. Evenly distribute the torn croissant pieces across the bottom of the dish.
  4. Layer Sausage: Sprinkle the browned sausage evenly over the croissant pieces to distribute the savory flavor throughout.
  5. Mix Eggs and Milk: In a medium bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until fully combined and slightly frothy.
  6. Combine and Pour: Pour the egg mixture evenly over the croissants and sausage in the baking dish to soak into all layers.
  7. Add Cheese Topping: Sprinkle the shredded cheddar and mozzarella cheeses evenly over the top to create a golden, melty crust.
  8. Bake: Place the casserole in the preheated oven and bake for 30 to 35 minutes, or until the egg mixture is set and the top is golden brown.
  9. Rest and Garnish: Allow the casserole to rest for 5 to 10 minutes after baking. Garnish with chopped parsley, if desired, before serving to add a fresh pop of color and flavor.

Notes

  • For convenience, assemble the casserole the night before and refrigerate, then bake fresh in the morning.
  • Add diced bell peppers or fresh spinach to the egg mixture for extra vegetables and nutrients.
