Hot Honey Mustard Ham and Cheese Sandwiches
Equipment
- 1 sheet pan
Ingredients
- 2 packages crescent roll dough
- ½ pound ham or a combination of both
- 6 slices Swiss cheese
- 3 tablespoons Dijon mustard
- 2 tablespoons whole grain mustard
- 1 teaspoon apple cider vinegar
- 1 tablespoon honey
- ⅛ teaspoon red pepper flakes
- 1 teaspoon poppy seeds
- 1 egg beaten (for egg wash)
Instructions
- Preheat your oven to 375°F. Line a baking sheet with parchment paper.

- Place a slice of Swiss cheese on the sauce. Add a generous portion of deli meat on top of the cheese. Top with the remaining hot honey mustard spread.
- Add the top layer of crescen roll. Brush the tops of the croissants with the beaten egg. Optionally, sprinkle sesame seeds or poppy seeds on top for added texture. Slice along the perforated edges using a pizza slicer into 8 sandwiches, before it goes into the oven.*
- Place the baking sheet in the preheated oven and bake for 20-25 minutes or until the croissants are golden brown and the cheese is melted. (If the top is getting too dark, cover with the aluminum foil to finish baking.)
