Preparation Instructions
  1. Begin by tearing 6-8 day-old croissants into large chunks and placing them evenly in a greased 3-quart baking dish.
  2. In a skillet over medium heat, brown 1 pound of ground sausage until fully cooked, about 5-7 minutes. Drain excess grease and layer sausage over croissant chunks.
  3. In a large mixing bowl, whisk together 6 eggs, 2 cups of whole milk, 1 teaspoon of salt, ½ teaspoon of black pepper, ½ teaspoon of garlic powder, and ½ teaspoon of onion powder.
  4. Pour the egg mixture over the croissant and sausage layers, ensuring even distribution. Sprinkle 1-2 cups of shredded cheddar cheese on top. Cover tightly with plastic wrap and refrigerate overnight.
  5. Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake for 45-50 minutes until golden brown.
  6. Let cool for 5-10 minutes before serving. Garnish with freshly chopped parsley.
