This recipe uses everyday ingredients that are easy to find and work well together for a balanced result.

• ⅓ cup unsalted butter, at room temperature
• 2 tablespoons Dijon mustard
• 2 green onions, thinly sliced
• 1 tablespoon honey
• ½ tsp sea salt
• ¼ tsp black pepper
• 12 croissants, halved horizontally
• 1 pound thinly sliced smoked deli ham
• 12 slices Swiss cheese, diagonally sliced
• 1 large egg white
• 2 teaspoons poppy seeds

You can swap ingredients based on what you have. If you don’t have Dijon mustard, a mild yellow mustard can be used, though the flavor will be different. For the cheese, Gruyere or a mild cheddar are good alternatives to Swiss. If you can’t find croissants, good quality brioche rolls can work. Ensure the ham is thinly sliced for even distribution and melting. For a slightly different flavor profile, consider adding a pinch of garlic powder to the butter mixture.

1. Preheat oven to 375 degrees F. Lightly oil a 9 x 13 baking dish or coat with nonstick spray.
2. In a small bowl, combine butter, Dijon mustard, green onions, and honey. Season with salt and pepper to taste.
3. Spread the butter mixture on the cut sides of each croissant half.
4. Assemble the sandwiches by filling the buttered croissants with layers of thinly sliced smoked deli ham and Swiss cheese.
5. Place the assembled croisant sandwiches in a single layer onto the prepared baking dish.
6. In a small bowl, whisk together the egg white and 1 tablespoon of water.
7. Brush the tops of the croissants with the egg white mixture.
8. Sprinkle the poppy seeds evenly over the tops of the brushed croissants.
9. Place the baking dish into the preheated oven and bake for 15-18 minutes, or until the croissants are golden brown and toasted and the cheese is melted and bubbly.
10. Let the sandwiches stand for 5 minutes before serving. Serve warm.

• Using cold butter will result in a lumpy spread and can tear the delicate croissants.
• Baking at too high a temperature can burn the croissants before the cheese has a chance to melt properly.
• Not brushing the tops with egg white and poppy seeds will result in a less appealing, less flavorful finish.

• Add a thin layer of a mild jam, like apricot or fig, to the butter mixture for a sweet and savory contrast.
• Incorporate a sprinkle of dried herbs, such as thyme or rosemary, into the butter spread.
• For a bit of heat, add a pinch of red pepper flakes to the butter mixture.

• Serve these warm croissant sandwiches as a delightful breakfast or brunch item.
• They make a perfect quick lunch alongside a fresh green salad.
• These are also great for an easy appetizer or a light dinner accompanied by a cup of soup.

Can I make this ahead?

While best enjoyed fresh, you can prepare the sandwiches (fill them) ahead of time and store them, covered, in the refrigerator for a few hours before baking. It’s recommended to bake them just before serving for optimal texture.

How do I store leftovers?

Allow the sandwiches to cool completely, then store them in an airtight container at room temperature for up to 2 days. Reheat gently in the oven.

These Easy Ham and Cheese Croissant Sandwiches are a reliable, quick, and adaptable recipe perfect for any meal. They’re a fantastic option for busy mornings, a satisfying lunch, or a simple dinner that delivers consistently delicious results with minimal fuss.
