Print Recipe

A quick and comforting breakfast casserole featuring buttery croissants soaked overnight in a cheesy egg custard, perfect for busy family mornings.

Ingredients

Scale
  • 6 large croissants, preferably day-old or slightly stale (cut into bite-sized pieces)
  • 8 large eggs, room temperature
  • 2 cups whole milk (or 1 cup milk + 1 cup heavy cream for extra richness)
  • 1 teaspoon Dijon mustard
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • ½ teaspoon garlic powder (optional)
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded Gruyère or mozzarella cheese
  • 2 tablespoons chopped fresh chives or parsley (optional)
  • ½ cup cooked bacon or sausage (optional)

Instructions

  1. Tear the croissants into roughly 2-inch pieces and place evenly in a 9×13 inch baking dish.
  2. In a large bowl, whisk together eggs, whole milk, Dijon mustard, salt, black pepper, and garlic powder until smooth and slightly frothy.
  3. Stir in 1 cup shredded sharp cheddar and ½ cup shredded Gruyère or mozzarella cheese. Fold in cooked bacon or sausage if using.
  4. Pour the egg and cheese mixture evenly over the croissants. Press down gently to help croissants absorb the custard. Cover tightly and refrigerate overnight or at least 6 hours.
  5. Preheat oven to 350°F (175°C). Remove cover and sprinkle remaining 1 cup shredded cheddar and ½ cup Gruyère evenly over the top.
  6. Bake uncovered for 45-50 minutes until edges are golden brown and a knife inserted comes out clean or with melted cheese.
  7. Let rest for 5-10 minutes before slicing. Garnish with fresh chives or parsley if desired.

Notes

Use day-old croissants for best texture. Do not skip the overnight soak to achieve a custardy, soft texture. Use room temperature eggs for even cooking. If the bake is too wet in the center after baking, add extra baking time. For gluten-free, use gluten-free croissants or bread cubes. For dairy-free, use plant-based milk and cheese alternatives.
