A delightful casserole featuring layers of buttery croissants, creamy eggs, sharp cheese, and earthy sautéed mushrooms, perfect for family gatherings.

  • Total Time: 50 minutes
  • Yield: 8 servings

Ingredients

  • 6-8 medium-sized croissants (preferably day-old)
  • 8 large eggs, beaten
  • 2 cups whole milk (or milk alternative)
  • 1-2 cups shredded cheese (cheddar, mozzarella, or a blend)
  • 1 cup fresh mushrooms (button, cremini, or shiitake)
  • 1 cup vegetables (bell peppers or spinach, optional)
  • Fresh thyme or parsley, to taste
  • Salt and pepper, to taste

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Tear croissants into bite-sized pieces and place in a greased 9×13 baking dish.
  3. In a skillet, melt a tablespoon of butter over medium heat. Sauté sliced mushrooms for about 5 minutes until golden and tender. Season with salt and pepper.
  4. In a mixing bowl, whisk together eggs, milk, salt, and pepper.
  5. Pour egg mixture over croissant pieces. Add sautéed mushrooms and sprinkle shredded cheese on top. Add herbs and stir gently.
  6. Bake for 30-35 minutes, until the top is golden and eggs are set.
  7. Allow to cool for 10 minutes before slicing.

Notes

Use day-old croissants for better absorption. Let the casserole sit for a few minutes before cutting to ensure clean slices.
