Ingredients
-
8 mini croissants
-
4 slices smoked cheddar cheese (or regular cheddar), halved
-
¾ pound deli-cut ham
-
3 tablespoons unsalted butter, softened
-
2 tablespoons yellow mustard
-
1 tablespoon honey
-
½–1 teaspoon Worcestershire sauce
-
1 large egg white
-
Poppy seeds, for sprinkling
Instructions
-
Preheat the Oven
Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. -
Prepare the Croissants
Slice each croissant in half horizontally. Place a half slice of cheese on the bottom half, add ham, then top with another half slice of cheese. Cover with the top half of the croissant. -
Make the Butter Spread
In a small bowl, mix the softened butter, mustard, honey, and Worcestershire sauce until smooth. -
Assemble
Spread the butter mixture evenly on the inside of each croissant sandwich. -
Arrange
Place the assembled croissants into the prepared baking dish. -
Egg Wash
Whisk the egg white with a splash of water. Brush the tops of the croissants and sprinkle with poppy seeds. -
Bake
Bake for 15–18 minutes, or until the cheese is melted and the tops are golden brown. -
Serve
Remove from the oven and serve warm.
Notes
-
Use room-temperature butter so the spread coats evenly without tearing the croissants.
-
Don’t overfill—too much ham or cheese can cause the croissants to split while baking.
-
Switch the cheese: Swiss, Gruyère, or provolone work beautifully.
-
Make ahead: Assemble up to 24 hours in advance, cover tightly, refrigerate, and bake when ready.
-
Reheat properly: Warm leftovers in the oven rather than the microwave to keep them flaky.
