  2. Layer the torn croissant pieces evenly in a greased baking dish.
  3. Sprinkle the crumbled bacon or sausage, cheese, and green onions over the croissant layer.
  4. Gently pour the egg mixture evenly over the top, ensuring all croissant pieces are well-coated.
  5. Cover the dish with plastic wrap or foil and refrigerate overnight (or for at least 2 hours).
  6. Preheat your oven to 350°F (175°C).

Notes

Serve with mixed fruit or a green salad for balance. For added flavor, drizzle with hot sauce or sour cream. Use day-old croissants for best results.
