Ingredients

For the Honey Mustard Spread

• 1 teaspoon honey

For the Croissant Sandwiches

• Croissants, sliced in half
• Prosciutto
• Sliced turkey deli meat
• Gouda cheese, sliced
• Fresh arugula

What Kind of Croissants Should I Use?

For the best croissant sandwich, use fresh, buttery croissants that are flaky on the outside and soft inside. You can use plain bakery croissants or your favorite store-bought croissants.

I recommend avoiding croissants that are overly sweet because the honey mustard spread already adds a touch of sweetness to the sandwich.

How to Make a Croissant Sandwich

Step 1: Make the Honey Mustard Spread

In a small bowl, combine the mustard seed spread with a little honey. Stir until well combined.

The honey adds just enough sweetness to balance the tangy mustard and salty meats.

Step 2: Prepare the Croissants

Carefully slice each croissant in half horizontally, keeping the croissant as intact as possible.

You can serve the croissant sandwich cold, or lightly warm the croissants before assembling.

Step 3: Add the Mustard Spread

Spread the honey mustard mixture over the inside of each croissant.

Don’t skip this step! The slightly sweet mustard spread brings all of the flavors together.

Step 4: Layer the Meats and Cheese

Add a layer of prosciutto followed by sliced turkey deli meat.

Top the turkey with sliced Gouda cheese. The Gouda adds a creamy, slightly nutty flavor that pairs beautifully with the salty prosciutto.

Step 5: Add the Arugula

Finish the croissant sandwich with a handful of fresh arugula.

The peppery arugula adds a fresh bite that keeps the sandwich from feeling too heavy.

Step 6: Serve

Place the top half of the croissant over the filling and gently press everything together.

Your easy croissant sandwich is ready to serve!

Can I Warm This Croissant Sandwich?

Absolutely! If you prefer warm sandwiches, assemble the croissant sandwich without the arugula and warm it in the oven until the cheese is softened and melty. Add the fresh arugula right before serving.

I love this method when I’m making these sandwiches for a cozy lunch.

Tips for Making the Best Croissant Sandwich

Don’t overfill the croissant. Croissants are delicate, so adding too much filling can make them difficult to eat.

Use good-quality deli meat. Since this recipe uses only a few ingredients, the flavor of each ingredient really shines.

Don’t skip the arugula. Its peppery flavor provides a nice contrast to the rich croissant, cheese, and meats.

Add the honey gradually. You want the mustard spread to have a subtle sweetness rather than tasting like honey mustard sauce.

Serve shortly after assembling. This keeps the croissant flaky instead of allowing it to become soggy.

Croissant Sandwich Variations

One of the best things about a croissant sandwich is how easy it is to customize.

Try swapping the Gouda for:

• Swiss cheese
• Provolone
• Havarti
• Brie
• Cheddar

You can also replace the arugula with spinach, spring greens, or lettuce.

For another variation, add thinly sliced tomatoes, roasted red peppers, caramelized onions, or avocado.

If you don’t have prosciutto, you can make this croissant sandwich with ham, roast beef, or even crispy bacon.

What to Serve with a Croissant Sandwich

This croissant sandwich is delicious on its own, but it becomes a complete lunch when served with a few simple sides.

Try serving it with:

• Caesar salad
• Homemade sourdough croutons
• Potato chips
• Fresh fruit
• Pasta salad
• Tomato cucumber salad
• Pickles
• A simple green salad

For a lunch gathering, arrange several croissant sandwiches on a platter alongside a big salad and a bowl of chips. It’s easy, beautiful, and doesn’t require hours in the kitchen.

Make-Ahead Instructions

If you’re preparing a croissant sandwich for a gathering, you can prepare the honey mustard spread and slice your ingredients ahead of time.

For the freshest results, assemble the sandwiches shortly before serving. This helps keep the croissants flaky and prevents the arugula from wilting.

If you’re making several sandwiches for a party, you can assemble them shortly before your guests arrive and arrange them on a large serving platter.

How to Store a Croissant Sandwich

A fully assembled croissant sandwich is best eaten the same day.

If you have leftovers, wrap each sandwich tightly and refrigerate for up to 1 day. Keep in mind that the croissant may lose some of its crisp, flaky texture after refrigeration.

For the best texture, store the components separately and assemble the croissant sandwich right before eating.
