Ingredients

Scale

Casserole

  • 8 large croissants (20 oz. or 570 g), left out overnight
  • 12 ounces Black Forest deli ham (340 g), chopped
  • 8 ounces shredded Swiss cheese
  • 8 large eggs
  • ½ cup half and half
  • 1 teaspoon salt
  • 1 teaspoon mustard powder
  • 1 teaspoon garlic powder
  • ¼ teaspoon white ground pepper or black pepper
  • ⅓ cup 100% pure maple syrup

Toppings

  • Powdered sugar
  • Raspberry jam


Instructions

  1. Prepare Croissants and Meat: Cut the croissants into 1 to 1.5 inch cubes and place in a large bowl. Chop the Black Forest ham into pieces, separating any layers, and add to the croissants.
  2. Add Cheese: Add shredded Swiss cheese to the croissant and ham mixture, then toss to combine evenly.
  3. Assemble in Baking Dish: Spread the croissant, ham, and cheese mixture evenly into a 9×13-inch baking pan and set aside.
  4. Mix Custard: In a medium bowl or large measuring cup, beat the eggs. Add half and half, maple syrup, salt, mustard powder, garlic powder, and white pepper, then whisk until well combined.
  5. Pour Custard Over Mixture: Evenly pour the egg mixture over the croissant mixture in the baking dish. Optionally, drizzle up to ¼ cup more maple syrup on top.
  6. Soak: Cover the casserole with aluminum foil and let it soak for at least 20 minutes while preheating the oven to 350°F.
  7. Bake Covered: Bake the casserole covered with foil for 20 minutes.
  8. Bake Uncovered: Remove the foil, rotate the pan, and bake an additional 25 minutes until the top is golden, toasted, and the eggs are fully set.
  9. Serve: Dust with powdered sugar and serve with raspberry jam and any extra maple syrup as desired.

Notes

  • Allow croissants to sit overnight to dry out slightly, helping them absorb the custard better.
  • Using Black Forest ham adds a sweet and smoky flavor, but other deli hams can be substituted.
  • Maple syrup can be adjusted for sweetness according to taste preferences.
  • Letting the casserole soak before baking improves texture and flavor absorption.
  • Ensure the eggs are fully cooked and set before serving to avoid sogginess.
  • Raspberry jam and powdered sugar add a nice balance of sweetness and tartness when serving.
