Ingredients You’ll Need

Each ingredient here has a purpose, from the flaky puff pastry that holds everything together to the sharp Gruyère and Swiss cheeses creating that classic savory flavor profile. I’ve found that quality cheese really makes a difference, so don’t skimp there!

• Cooking spray: Keeps your muffin tin clean and helps the pastries release easily.
• All-purpose flour: For dusting your surface so the puff pastry doesn’t stick and for thickening the béchamel sauce.
• Frozen puff pastry sheet: The flaky, buttery base for the bites—thaw it well for easy handling.
• Large egg: Used both for the egg wash to give the pastry a golden finish and within the béchamel sauce.
• Whole milk: Provides creaminess to the béchamel while keeping it light and smooth.
• Heavy cream: Adds richness to the sauce—don’t skip this or the sauce won’t be as luxurious.
• Unsalted butter: Essential for making the roux, giving the béchamel its silky texture.
• Dijon mustard: Gives a subtle tang and depth to the sauce; it brightens those cheesy flavors.
• Kosher salt: Perfect for seasoning without overdoing it.
• Freshly ground black pepper: Adds a gentle spice without overpowering.
• Ground nutmeg: A secret ingredient in béchamel that adds just the right warmth and complexity.
• Shredded Gruyère: The star cheese in Croque Monsieur; creamy and slightly nutty.
• Shredded Swiss cheese: Complements the Gruyère with its mild, melty goodness.
• Sliced deli ham: Choose good-quality ham for that salty, smoky bite.
• Finely grated Parmesan: A final touch of sharpness sprinkled on top before baking.
• Fresh thyme: For garnish—adds freshness and a charming herbal note.

Variations

I love to tweak this Croque Monsieur Bites Recipe depending on the occasion or what cheese I have on hand. Don’t hesitate to make it your own — swapping cheeses or adding herbs can really up the flavor game.

• Cheese swap: I’ve tried adding a bit of sharp cheddar or fontina for a different melt and everyone loved it!
• Ham alternatives: Feel free to use smoked turkey or prosciutto if you want a leaner or saltier twist.
• Herb additions: Fresh basil or tarragon stirred into the béchamel gives a seasonal flair I especially enjoy in spring.
• Vegetarian option: Skip ham and add sautéed mushrooms or caramelized onions for a rich, meat-free version.

How to Make Croque Monsieur Bites Recipe

Step 1: Prep the Puff Pastry Cups

Start by greasing a 12-cup muffin tin with cooking spray to ensure easy removal later. On a lightly floured surface, roll your thawed puff pastry into a 12″ by 10″ rectangle — this makes the pastry easier to shape. Cut the pastry into 12 squares and gently stretch each one before pressing into the muffin cups so they form little shells. Brush each with an egg wash made from one beaten egg mixed with a tablespoon of water, then pop the entire tray in the fridge to chill while you make the béchamel.

Step 2: Warm Your Dairy for Béchamel

In a small saucepan over medium heat, warm the whole milk and heavy cream together until just hot but not boiling — about 2 minutes. This step helps the sauce pour smoothly and cook evenly in the next step.

Step 3: Make the Béchamel Sauce

In another saucepan, melt the butter over medium-low heat and whisk in a tablespoon of flour. Keep whisking for about 2 minutes until it turns lightly golden and smooth — this is your roux, which thickens the sauce. Slowly stream in the warm milk and cream, whisking constantly to avoid lumps. Cook until the sauce thickens, another 2 minutes, then remove from heat and stir in Dijon mustard, salt, pepper, and a pinch of nutmeg. This béchamel adds that rich, silky texture that makes this recipe special.

Step 4: Layer the Ingredients in Your Pastry Cups

Combine the Gruyère and Swiss cheeses in a bowl. Spread a teaspoon of béchamel in each pastry cup’s bottom, then tear your ham to fit and layer it on top. If your ham is thin, don’t be shy—add two layers for a heartier bite. Add a tablespoon of cheese mixture, then repeat the ham and cheese layers. Finish with a sprinkling of Parmesan on top. Chill these filled cups in the fridge for about 10 minutes before baking — this helps everything hold its shape.

Step 5: Bake to Golden Perfection

Preheat your oven to 400°F (200°C). Bake the Croque Monsieur Bites for 20 to 23 minutes until the pastry is puffed and golden brown, and the cheese is bubbling and delicious. Keep an eye on them near the end so they don’t overbrown. The warm, melty cheese and crisp pastry are just irresistible at this point!

Step 6: Cool and Serve

Set the muffin pan on a wire rack and let the bites cool for 5 to 10 minutes. This resting time helps the béchamel set so they hold together when you remove them. Use a small offset spatula or a dull knife to gently loosen the pastries, then transfer to a serving platter. I love topping each with a little fresh chopped thyme — it adds a lovely herbal note and pretty color right before serving. Serve them warm and get ready for compliments!

How to Serve Croque Monsieur Bites Recipe

Garnishes

I always top these bites with fresh chopped thyme for a pop of color and subtle earthiness that cuts through the richness. A light dusting of extra Parmesan right after baking adds some extra savory crunch, and sometimes I drizzle a tiny bit of whole grain mustard alongside for dipping if I’m feeling fancy.

Side Dishes

Pair your Croque Monsieur Bites with a crisp green salad tossed in a lemon vinaigrette to balance the richness. I also love serving them with a small bowl of tomato bisque or a chilled glass of sparkling wine to keep things light and celebratory.

Creative Ways to Present

For special occasions, I like to arrange the bites on a slate board scattered with sprigs of thyme and tiny bowls of mustards and chutneys. Using mini skewers or cocktail forks makes them easy for guests to grab. Adding edible flowers sometimes turns these into a beautiful centerpiece as well.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (which is rare in my house!), store them in an airtight container in the fridge for up to 2 days. I recommend reheating in the oven to keep the pastry crisp rather than microwaving, which can make them soggy.

Freezing

I’ve had good success freezing the assembled (but unbaked) Croque Monsieur Bites. Just wrap the muffin tin tightly with plastic wrap and foil, then pop it in the freezer for up to 1 month. When ready to bake, just add a few extra minutes to the baking time.

Reheating

Reheat leftovers in a preheated 350°F oven for 10-15 minutes to warm through and bring back that golden crispiness. Avoid microwaving if you want to keep the flaky texture intact — I learned the hard way with soggy pastry!
