A warm, flaky croissant stuffed with smoky ham and melted cheese is a protein-packed breakfast that feels indulgent yet effortless. This family-friendly grab-and-go option satisfies every morning.
Preheat your oven to 375°F and line a baking sheet with parchment paper for even heat distribution.
Slice the croissants horizontally without cutting all the way through, creating a pocket for the filling.
Spread a thin layer of Dijon mustard inside each croissant, then add 2 slices of smoked ham and 1 slice of Swiss cheese per croissant.
Brush the tops of the croissants lightly with melted unsalted butter and sprinkle a pinch of black pepper to enhance flavor.
Bake croissants for 8–10 minutes until the cheese is melted and the croissants are golden brown and crisp—do not overbake to avoid drying out the pastry.
