Description

This Monte Cristo breakfast casserole transforms the beloved sandwich into an easy, make-ahead dish perfect for brunch. Buttery croissants, layers of ham and Swiss cheese, and a rich custard bake into a golden, decadent casserole. Finished with powdered sugar and served with raspberry jam, this dish delivers the perfect balance of sweet and savory flavors.


Ingredients

Scale
  • 6 large croissants, torn into large pieces
  • 8 oz deli ham, sliced
  • 2 cups Swiss cheese, shredded
  • 6 large eggs
  • 1 cup whole milk
  • 1/2 cup heavy cream
  • 1 tbsp Dijon mustard
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • Powdered sugar, for garnish
  • Raspberry jam, for serving

Instructions

  1. Prepare the dish: Grease a 9×13-inch baking dish and preheat the oven to 375°F (190°C).
  2. Layer the ingredients: Spread half of the croissant pieces in the dish. Layer with ham and Swiss cheese. Repeat with remaining croissants, ham, and cheese.
  3. Make the custard: In a bowl, whisk together eggs, milk, heavy cream, Dijon mustard, salt, and pepper.
  4. Soak the casserole: Pour the custard evenly over the croissants. Let sit for at least 10 minutes, or refrigerate overnight for best results.
  5. Bake: Cover with foil and bake for 25 minutes. Remove foil and bake for another 15 minutes, until golden brown and set.
  6. Finish & serve: Dust with powdered sugar and serve warm with raspberry jam.

Notes

  • Use day-old croissants for better texture.
  • Broil for 2-3 minutes at the end for a crispier top.
  • Try alternative cheeses like Gruyère or cheddar for a different twist.
  • Savory variation: Add a pinch of cayenne or smoked paprika to the custard.
