Hot Ham and Swiss Croissants Recipe
Hot Ham and Swiss Croissants are buttery, flaky sandwiches filled with savory deli ham, melted Swiss cheese, and a sweet-tangy honey mustard sauce. Wrapped in foil and baked until warm and gooey, they’re an easy option for lunch, dinner, brunch, or a party snack.
They come together with just a few ingredients and need only a short time in the oven. Serve them fresh and warm, when the cheese is melted and the croissants are soft.

Hot Ham and Swiss Croissants
Equipment
- Small Mixing Bowl
- Spoon or Spatula
- Aluminum foil
- Pastry Brush (optional)
Ingredients
- Honey Mustard Sauce
- 2 tbsp Dijon mustard
- 1 tbsp honey
- 1 tbsp brown sugar
- Sandwiches
- 4 large croissants split in half
- 8 slices Swiss cheese
- ½ lb thinly sliced deli ham
Instructions
- Preheat the oven to 350°F.
- In a small bowl, mix the Dijon mustard, honey, and brown sugar until smooth and well combined.
- Spread the honey mustard mixture evenly over the cut sides of all four croissants.
- Place one slice of Swiss cheese on each croissant half. Add the deli ham to the bottom half of each croissant, using more or less according to your preference.
- Place the croissant halves back together to form sandwiches.
- Wrap each sandwich individually in aluminum foil and arrange them on a baking sheet.
- Bake for 20–25 minutes, or until the sandwiches are heated through and the Swiss cheese is completely melted.
- Carefully unwrap the hot croissants and serve immediately.
Notes
- Wrapping the croissants in foil helps keep them soft and prevents the delicate pastry from becoming overly browned while the cheese melts.
- Thinly sliced deli ham heats more quickly, but leftover holiday ham also works well.
- Larger croissants work best for the main-dish version; mini croissants can be used for smaller party sandwiches.
- Assemble the sandwiches up to 24 hours ahead, wrap them individually, and refrigerate until ready to bake. Add 2–3 extra minutes to the baking time when baking directly from the refrigerator.
- You can substitute cheddar, provolone, Havarti, or another good melting cheese for Swiss.

Troubleshooting
- The croissants brown too quickly: Keep them wrapped in foil while baking so the pastry stays soft as the filling heats.
- The cheese hasn’t melted yet: Return the wrapped sandwiches to the oven for a few more minutes, checking until the cheese is fully melted.
- The filling feels too salty: Choose a lower-sodium ham or cheese, or use a lighter layer of ham.
- The sauce tastes too sweet: Add a little more Dijon mustard to balance the honey and brown sugar.
- The croissants feel soggy: Avoid adding extra sauce beyond what’s needed to coat the cut sides, and serve soon after baking.
- The sandwiches are cold in the center: Make sure they’re arranged in a single layer on the baking sheet and bake until heated through.
Variations
- Use a different cheese: Swap Swiss for cheddar, provolone, Havarti, or another good melting cheese.
- Make mini sandwiches: Use mini croissants for smaller portions at brunches or parties.
- Use leftover ham: Replace deli ham with thinly sliced leftover holiday ham.
- Adjust the mustard flavor: Add a little more Dijon for a tangier sauce.
- Add pickles: Include a few thin pickle slices for a tangy crunch.
- Make them more savory: Add a small amount of black pepper to the honey mustard sauce.
