Ingredients You’ll Need
To make your Croque Monsieur Bites Recipe shine, you’ll want fresh, quality ingredients that complement each other beautifully. Trust me, using Gruyère along with Swiss cheese adds a rich depth, and the béchamel sauce brings everything together with creamy goodness.
- Cooking spray: For greasing the muffin tin efficiently to ensure easy removal later.
- All-purpose flour: Helps thicken the béchamel sauce smoothly without lumps.
- Frozen puff pastry sheet: The flaky crust that makes this recipe irresistible — thawed before working.
- Large egg: Used to create a simple egg wash for a golden, glossy finish on the pastry.
- Whole milk: Warms gently to blend perfectly with butter and flour for the béchamel.
- Heavy cream: Adds richness and a silky texture to the béchamel sauce.
- Unsalted butter: The base fat in the roux that gives the creamy sauce depth and flavor.
- Dijon mustard: Provides a subtle tang in the béchamel, cutting through the richness.
- Kosher salt: Seasoning to balance all the flavors.
- Freshly ground black pepper: Adds a light bite and warmth to the sauce.
- Ground nutmeg: A pinch brings a lovely warmth and traditional béchamel aroma.

Variations
I love how adaptable the Croque Monsieur Bites Recipe is — once you’ve nailed the basic version, feel free to get creative and make it your own. You can swap cheeses, switch up the meat, or even add herbs and spices to suit your taste or dietary needs.
- Cheese swap: I once used sharp cheddar and mozzarella for a twist, and it still turned out wonderfully melty and flavorful.
- Meat-free option: Try using sautéed mushrooms or spinach with caramelized onions for a vegetarian take that’s equally delicious.
- Spice it up: Adding a pinch of smoked paprika or a few dashes of hot sauce to the béchamel can give these bites a subtle kick.
- Mini breakfast bites: Layer in some cooked bacon or scrambled eggs for brunch-perfect Croque Monsieur Bites.
How to Make Croque Monsieur Bites Recipe
Step 1: Prepare Your Pastry Cups
First, grease a 12-cup muffin tin generously with cooking spray — trust me, this helps the pastry come out without any hassle later. On a lightly floured surface, roll out your thawed puff pastry sheet gently into a 12″ x 10″ rectangle. Then cut it into 12 equal squares. I like to slightly stretch each square just a bit before pressing it into the muffin cups to create little puff pastry shells that hold all that delicious filling.
Brush the inside of each pastry cup with a light coat of egg wash (egg beaten with water) to give them that lovely golden finish when baked. Pop the tray into the fridge to chill until you’re ready for the filling – it helps keep the pastry from shrinking during baking.
Step 2: Make the Béchamel Sauce
Warm your milk and heavy cream gently in a small saucepan until just heated through, about 2 minutes. Meanwhile, melt butter in another saucepan over medium-low heat and whisk in flour, cooking it until it’s smooth and smells lightly toasted, about 2 minutes. Slowly pour in the warm milk mixture, whisking constantly to avoid lumps, and keep cooking until the sauce thickens — about 2 minutes.
This is where the magic happens! Once thick, remove from heat and stir in Dijon mustard, salt, pepper, and nutmeg to elevate the flavor. Béchamel is the secret ingredient that makes these bites irresistibly creamy and rich.
Step 3: Assemble the Croque Monsieur Bites
Grab a medium bowl and combine your shredded Gruyère and Swiss cheeses. Now, spoon about 1 teaspoon of béchamel sauce into the bottom of each chilled pastry cup — this keeps the layers moist and flavorful. Tear ham slices into pieces that fit nicely inside the cups; if your ham is thin, use two layers for a satisfying meaty bite.
Layer the ham and cheese inside the pastry cups: béchamel, ham, 1 tablespoon cheese mix, more ham, and cheese again. Top everything with a little Parmesan for that perfectly crisp and savory finish. Let these chill in the fridge for about 10 minutes before baking — this makes them bake evenly and keeps their shape.
Step 4: Bake Until Golden and Bubbling
Preheat your oven to 400°F (200°C). Place the muffin tin on the center rack and bake for 20 to 23 minutes, or until the pastry is golden brown and the cheese filling is bubbling beautifully. I love watching that cheese bubble up and bubble out just a tad — it means it’s time to take them out and enjoy!
Step 5: Cool, Release, and Serve
Once out of the oven, set the muffin tin on a wire rack and let the bites cool for 5 to 10 minutes. This resting step lets the filling set slightly, making the bites easier to handle. Use a small offset spatula or a dull knife to carefully loosen the edges before removing them from the tin to avoid any tearing.
I like to transfer mine onto a serving plate, sprinkle chopped fresh thyme on top for a lovely herbal aroma and a splash of color, and serve them warm. Honestly, you’ll want to eat the whole batch straight away.
Pro Tips for Making Croque Monsieur Bites Recipe
- Chilling is Key: Don’t skip refrigerating the pastry cups before and after filling — this helps prevent shrinkage during baking and keeps the layers neat.
- Watch Your Béchamel Consistency: The sauce should be thick but still spreadable; if it’s too thin, your filling can become watery and messy.
- Don’t Overfill: Filling cups too full can cause spilling during baking, so stick to the suggested layers for perfect bites.
- Use a Sharp Knife or Offset Spatula: This makes removing the bites from the muffin tin cleaner and keeps them intact.
How to Serve Croque Monsieur Bites Recipe
Garnishes
I’m a big fan of fresh herbs to brighten up rich flavors, so I usually finish these Croque Monsieur Bites with a sprinkle of chopped fresh thyme. Sometimes, I add a few freshly cracked black peppercorns or a drizzle of good-quality mustard on the side for dipping if I want an extra flavorful kick.
Side Dishes
These bites pair beautifully with a crisp green salad dressed with lemon vinaigrette or a light sauté of seasonal vegetables. If you want to turn this into a heartier meal, consider serving with a bowl of tomato soup — it’s a classic combo and always a crowd favorite at my home.
Creative Ways to Present
For parties, I’ve served these Croque Monsieur Bites on a wooden board surrounded by little bowls of Dijon mustard, cornichons, and olives — it creates a rustic French vibe and invites guests to help themselves. You can also garnish each bite with a tiny edible flower or microgreens for a delicate, elegant touch when hosting a special brunch or holiday gathering.
Make Ahead and Storage
Storing Leftovers
If you end up with leftovers, just store them in an airtight container in the fridge. I recommend reheating them in the oven to bring back that crispiness in the puff pastry rather than the microwave, which can make them soggy.
Freezing
I’ve frozen these Croque Monsieur Bites before, either baked or just assembled but unbaked. When frozen unbaked, you can bake them straight from the freezer by adding a few extra minutes to the baking time. Just be sure to wrap them well to avoid freezer burn.
Reheating
The best way to reheat leftovers is in a 350°F oven for about 10 minutes until warmed through and the pastry gets that perfect flaky crunch again. Avoid the microwave unless you’re in a pinch since it tends to soften the pastry, losing that wonderful texture.
FAQs
-
Can I make Croque Monsieur Bites ahead of time?
Absolutely! You can assemble the Croque Monsieur Bites a few hours ahead and refrigerate them until you’re ready to bake. This makes them perfect for prepping before guests arrive. Just be sure to bring them back to the fridge if they’ve been sitting out while preparing other things, so the pastry stays firm and bakes nicely.
-
Can I substitute different cheeses in this recipe?
Yes, you can swap Gruyère and Swiss with other good melting cheeses like Comté, Emmental, or even sharp cheddar for a different flavor profile. The key is to use cheeses that melt well and complement the ham and béchamel sauce.
-
Is there a vegetarian version of Croque Monsieur Bites?
Definitely! Replace the ham with sautéed mushrooms, spinach, or roasted veggies to keep the savory flavor. The béchamel and cheese combo still delivers plenty of richness and satisfaction.
-
How do I prevent soggy pastry bottoms?
Chilling the pastry cups before baking and starting with a layer of béchamel sauce in the bottom helps create a barrier to keep the puff pastry crisp. Also, make sure to bake at the right temperature and for the full time until golden.
-
Can I use homemade puff pastry?
Of course! Homemade puff pastry can elevate these bites even more with its extra flakiness and buttery layers. Just ensure it’s rolled out to the suggested size and thickness for best results.
Final Thoughts
Honestly, the Croque Monsieur Bites Recipe is one of those dishes that makes cooking feel joyous and rewarding. I love how it brings classic French flavors into a fun, shareable bite that everyone can enjoy.

Ingredients
Pastry Base
- Cooking spray
- 1 (14-oz.) sheet frozen puff pastry, thawed
- 1 Tbsp. all-purpose flour, plus more for surface
- 1 large egg
- 1 Tbsp. water (for egg wash)
Béchamel Sauce
- 1/2 cup whole milk
- 2 Tbsp. heavy cream
- 1 Tbsp. unsalted butter
- 1 Tbsp. all-purpose flour
- 1 tsp. Dijon mustard
- 1/4 tsp. kosher salt
- 1/8 tsp. freshly ground black pepper
- 1/8 tsp. ground nutmeg
Filling
- 1 1/3 cups shredded Gruyère cheese
- 2/3 cup shredded Swiss cheese
- 1/4 lb. sliced deli ham
- 1/2 cup finely grated Parmesan cheese
Garnish
- Chopped fresh thyme, for serving
Instructions
- Prepare Pastry Cups: Grease a standard 12-cup muffin tin with cooking spray. On a lightly floured surface, roll out the thawed puff pastry sheet into a 12-inch by 10-inch rectangle. Cut the dough into 12 equal squares. Gently stretch each square slightly larger and press each into the bottom and sides of the muffin cups to form little pastry shells. In a small bowl, beat the egg with 1 tablespoon water to make an egg wash, then brush a thin layer over each pastry shell. Refrigerate the prepared shells until ready to fill.
- Warm Milk and Cream: In a small saucepan over medium heat, warm the whole milk and heavy cream together just until heated through, about 2 minutes. Remove from heat and keep warm.
- Make Béchamel Sauce: In another small saucepan over medium-low heat, melt the butter. Whisk in 1 tablespoon flour and cook, stirring constantly, until the mixture is smooth and lightly toasted, about 2 minutes. Gradually pour the warmed milk mixture into the butter and flour mixture in a slow, steady stream while whisking continuously. Continue cooking and whisking until the sauce thickens, about 2 minutes. Remove from heat and stir in Dijon mustard, kosher salt, black pepper, and nutmeg until combined.
- Assemble Croque Monsieur Bites: In a medium bowl, mix together the shredded Gruyère and Swiss cheeses. Spread about 1 teaspoon of the béchamel sauce into the bottom of each pastry cup. Tear pieces of deli ham to fit the bottom of each cup (use 2 layers if ham is thin), and place over the béchamel. Top the ham with 1 tablespoon of the cheese mixture, then add another layer of ham, followed by another tablespoon of cheese mixture. Sprinkle finely grated Parmesan cheese on top of each filled pastry cup. Refrigerate the assembled bites until the filling is cold, about 10 minutes.
- Bake: Preheat the oven to 400°F (200°C). Bake the croque monsieur bites in the preheated oven until the pastry is golden brown and the cheese is bubbling, approximately 20 to 23 minutes.
- Cool and Serve: Remove the baking pan from the oven and place it on a wire rack to cool for 5 to 10 minutes. Carefully loosen the edges of the pastries from the muffin cups using a small offset spatula or a dull knife and remove each bite from the pan. Transfer to a serving platter, garnish with chopped fresh thyme, and serve warm.
Notes
- Use frozen puff pastry and thaw according to package instructions for best results.
- When rolling out pastry, avoid making it too thin to prevent tears when molding the cups.
- For a more intense flavor, the cheeses can be freshly shredded rather than pre-shredded.
- If the ham slices are thick, one layer per cup is sufficient; adjust accordingly for thin ham.
- These bites can be prepared ahead and refrigerated; bake just before serving.
- Fresh thyme adds a bright aromatic finish, but other herbs like parsley or chives can be used.
