Variations for Croque Monsieur Puffs

One of the best things about Croque Monsieur Puffs is how easily they adapt to your preferences or dietary needs. Feel free to experiment and make them uniquely yours.

• Vegetarian twist: Swap ham with sautéed mushrooms or roasted vegetables for a meat-free option.
• Spicy kick: Add a dash of smoked paprika or cayenne in the béchamel for subtle heat.
• Cheese swap: Try Emmental or Swiss cheese for different melting characteristics and taste.

How to Make Croque Monsieur Puffs

Step 1: Prepare the béchamel sauce

Start by melting butter in a saucepan over medium heat. Whisk in flour and cook for about two minutes to form a roux, ensuring there’s no raw flour taste. Gradually add milk while continuously whisking to avoid lumps, cooking until the sauce thickens smoothly. Remove from heat, stir in a pinch of nutmeg, a teaspoon of Dijon mustard, salt, and pepper to taste. Set aside to cool slightly.

Step 2: Assemble the filling

Chop the ham into small pieces and grate the Gruyère cheese. Once the béchamel has cooled enough, gently fold in the ham and most of the cheese, reserving some for topping the puffs later. This mixture forms a creamy, flavorful filling that’s the heart of the Croque Monsieur Puffs.

Step 3: Cut and fill puff pastry

Roll out the thawed puff pastry sheets to smooth out any creases, then cut them into squares approximately 3 by 3 inches. Spoon a generous amount of the béchamel mixture into the center of half the pastry squares, leaving edges clear for sealing.

Step 4: Seal and top

Moisten the edges with water or egg wash, then place another square of pastry on top to create a pocket. Press edges firmly with a fork to seal. Brush each puff generously with egg wash for that shining golden finish. Sprinkle the reserved Gruyère on top for a bubbly, crispy cheese crust.

Step 5: Bake to perfection

Arrange the filled puffs on a baking sheet lined with parchment paper. Bake in a preheated oven at 400°F (200°C) for 15 to 20 minutes, or until pastries are puffed up and beautifully golden. Let them cool for a few minutes before serving.

Pro Tips for Making Croque Monsieur Puffs

• Use cold puff pastry: Keep pastry chilled before baking for maximum flakiness and rise.
• Don’t overfill: Too much filling can cause leakage; balance quantity for neat puffs.
• Sharp cheese: Freshly grated Gruyère melts more smoothly than pre-shredded.
• Rest béchamel: Allow béchamel to cool slightly so it’s easier to handle during assembly.
• Even egg wash: Brush carefully for an even, glossy surface and rich golden color.
• Serve warm: Puffs are best enjoyed fresh from the oven while flaky and melty.

How to Serve Croque Monsieur Puffs

Garnishes

Enhance your Croque Monsieur Puffs with a sprinkle of finely chopped fresh parsley or chives for a pop of color and fresh flavor. A tiny dollop of whole grain mustard on the side elevates the savoriness beautifully.

Side Dishes

Serve these puffs alongside a crisp green salad dressed with a light vinaigrette or a simple tomato salad to cut through the richness. For brunch, pair with a fresh fruit platter or a chilled sparkling wine to impress guests.

Creative Ways to Present

Arrange Croque Monsieur Puffs on a wooden board or elegant serving tray with seasonal edible flowers and herbs for visual appeal. Stacking them in tiers can create a stunning centerpiece at your table, inviting guests to indulge.

Make Ahead and Storage

Storing Leftovers

If you have any leftover puffs, store them in an airtight container in the refrigerator for up to two days. To keep the pastry crisp, place a paper towel beneath them and reheat just before serving.

Freezing

You can freeze uncooked Croque Monsieur Puffs by assembling them, then placing them on a baking sheet to freeze individually before transferring to a freezer bag. Bake directly from frozen, adding a few extra minutes to baking time.

Reheating

Reheat leftover puffs in a preheated oven at 350°F (175°C) for 8-10 minutes until warmed through and crisp again. Avoid microwaving to prevent soggy pastry.
