Ingredients

For the Sandwiches:

• 4 large buttery croissants (fresh or lightly toasted)
• 8 slices deli ham (or leftover baked ham, thinly sliced)
• 4 slices Swiss cheese (or Gruyère for extra nuttiness)
• 2 tablespoons Dijon mustard (optional)
• 2 tablespoons mayonnaise (optional)
• 1 tablespoon unsalted butter (for toasting, optional)

For Garnish / Serving:

• Pickles or cornichons (optional, for crunch)
• Side salad, chips, or soup (optional pairings)

Quick Directions

1. Slice croissants in half lengthwise.
2. Spread mustard or mayo on one side if desired.
3. Layer ham and Swiss cheese inside.
4. Toast in a skillet or oven until cheese melts.
5. Serve warm with optional sides.

Step-by-Step Preparation Method:

Step 1: Prep the Croissants

• Slice croissants horizontally with a serrated knife. Place the bottom halves on a clean surface or baking sheet.

Step 2: Add Condiments (Optional)

• Spread Dijon mustard or mayonnaise on the inside of each croissant half, depending on your flavor preference.

Step 3: Layer Ham and Cheese

• Place 2 slices of ham on each croissant bottom.
• Add a slice of Swiss cheese over the ham.

Step 4: Toast the Sandwich

• Option 1: Skillet Method
  • Heat a skillet over medium-low. Add a touch of butter.
  • Place sandwiches in the skillet, press gently with a spatula, and cover with a lid until the cheese melts (~3–4 minutes). Flip carefully to toast the top if desired.
• Option 2: Oven Method
  • Preheat oven to 350°F (175°C). Place sandwiches on a baking sheet and heat for 8–10 minutes until cheese melts and croissants are warm.

Step 5: Serve

• Remove from heat, close the sandwiches with the croissant tops, and serve immediately.

How to Serve

Serve these sandwiches warm with a simple green salad, kettle chips, or a cup of tomato or French onion soup. For brunch, pair with mimosas, fresh fruit, or a latte.

Tips for this Recipe:

• Use fresh croissants: Bakery-fresh croissants elevate the flavor and texture.
• Layer properly: Place cheese between ham layers to help it melt evenly.
• Don’t over-toast: Croissants can burn easily, so toast on low to medium heat.
• Add freshness: A slice of tomato or a handful of arugula can balance the richness.

Variations:

• Breakfast Croissant: Add scrambled eggs or a fried egg.
• Turkey & Swiss: Swap ham for turkey breast for a lighter option.
• Croque-Monsieur Style: Add béchamel sauce and broil until golden.
• Sweet & Savory: Add a smear of fig jam or honey mustard for contrast.
• Vegetarian: Replace ham with sautéed mushrooms or spinach.

Freezing and Storage

• Storage: Wrap leftover sandwiches tightly in foil and refrigerate for up to 2 days.
• Reheating: Warm in the oven at 300°F (150°C) for 10 minutes to re-crisp.
• Freezing: Not recommended, as croissants lose their flaky texture when frozen and thawed.

Special Equipment Needed

• Serrated bread knife
• Skillet or nonstick pan (for stovetop method)
• Baking sheet (for oven method)

A: Yes, but fresh bakery croissants give the best texture and flavor.
