Preheat the oven to 375 degrees F. Line a baking sheet with parchment paper and set aside.
Unroll the crescent rolls, then separate into triangles at the dotted line. Lay 1 slices black forest ham, folded, and 1 slices swiss cheese on the widest part of 1 refrigerated crescent rolls triangle. Repeat with the other crescent rolls.
Tightly roll each of the crescent rolls up, starting at the wide end. Place onto the prepared baking sheet, tip-side down, leaving space between each roll.
In a small bowl, whisk together 3 tablespoons salted butter, 1 tablespoon brown sugar, and 1/4 teaspoon dried parsley. Brush over each crescent roll.
Bake for 12-15 minutes, or until golden brown and puffed up. Some cheese may melt out while baking - parchment paper will make cleanup easier.
Remove from the oven and allow to cool for 5 minutes before serving.
Notes
Air Fryer: Assemble and glaze the crescent rolls as directed. Place them in the air fryer basket with space between each roll, working in batches if needed. Air fry at 340°F for 6–8 minutes, or until puffed and golden brown. Check early, since air fryer models vary.
Store leftovers in the fridge in a covered container for 3 to 4 days.
Some Swiss cheese may melt out of the corners, so use parchment paper for easy cleanup.
Brush each roll generously with the brown sugar butter glaze before baking for a lightly sweet, savory finish and golden tops.
