Ingredients You’ll Need
The ingredients in this Croque Monsieur Bites recipe come together beautifully to create those flaky, cheesy pockets of yum. A quick tip for shopping: using a high-quality Gruyère and Swiss cheese makes all the difference for that authentic flavor.
- Cooking spray: Helps the pastry cups release easily without sticking to the muffin tin.
- All-purpose flour: Essential for the béchamel sauce and for dusting the surface when rolling out puff pastry.
- Frozen puff pastry sheet: Thaw it properly for easy rolling—this is your crispy, buttery base.
- Large egg: Used for making egg wash to achieve that golden, glossy finish on the pastry.
- Whole milk: Warms up for the béchamel sauce, lending creaminess.
- Heavy cream: Adds richness to the béchamel, making it silky smooth.
- Unsalted butter: The fat base that toasts with flour to form the roux for béchamel.
- Dijon mustard: Gives the béchamel sauce a subtle tang that balances the richness perfectly.
- Kosher salt, black pepper, ground nutmeg: Seasonings that enhance and deepen the flavors subtly.
- Gruyère cheese: Offers a nutty, melty cheese flavor that’s classic in a Croque Monsieur.
- Swiss cheese: Adds a mild, sweet creaminess that complements Gruyère well.
- Sliced deli ham: Layered inside for that salty, meaty goodness.
- Finely grated Parmesan cheese: Sprinkled on top to add a savory, crisp crust when baked.
- Chopped fresh thyme: A lovely fresh herb finishing touch that brightens the baked bites.
Variations
I love experimenting with this Croque Monsieur Bites recipe, and you can easily customize it to your liking or dietary needs. Don’t hesitate to swap cheeses or try different meats to keep things interesting.
- Make it vegetarian: I swapped ham for sautéed mushrooms and caramelized onions once, and it was just as delicious – you get that savory depth without meat.
- Spice it up: Adding a pinch of smoked paprika or cayenne to the béchamel gave a subtle heat that my friends really enjoyed one time I tried it.
- Gluten-free version: Using gluten-free puff pastry and substituting the flour in the béchamel with a gluten-free alternative works well; just be sure to whisk thoroughly to avoid lumps.
- Herb twist: Mixing things up with fresh rosemary or tarragon instead of thyme creates a lovely fresh aroma and changes the flavor profile.
How to Make Croque Monsieur Bites Recipe
Step 1: Prepare and shape your puff pastry cups
Start by greasing a 12-cup muffin tin with cooking spray so nothing sticks later—it’s crucial for easy removal. On a lightly floured surface, roll your thawed puff pastry into a 12″ x 10″ rectangle, then cut it into 12 squares. Gently stretch each square just a bit and press it into the muffin cups, making sure it covers the bottom and sides neatly. Don’t skip the egg wash here—a light brush with beaten egg and water makes the pastry golden and shiny. Pop the tin into the fridge while you continue prepping. I learned the hard way that skipping refrigeration here can cause the dough to shrink during baking, so chilling keeps the shape perfect.
Step 2: Warm your milk and cream for the béchamel
In a small saucepan over medium heat, gently warm the milk and heavy cream together until just heated through. This only takes about 2 minutes—no need to boil it. Warming these liquids before adding them to the roux prevents lumps and helps you get that silky smooth béchamel we’re aiming for.
Step 3: Make the béchamel sauce with all the flavorful seasonings
Now, melt your butter over medium-low heat in another saucepan. Add the flour, whisking constantly, and cook it for about 2 minutes until smooth and golden—this cooks out the raw flour taste. Slowly pour your warm milk mixture into the butter-flour roux, whisking continuously so it thickens nicely and stays lump-free. Once thickened, remove from heat and stir in the Dijon mustard, salt, pepper, and nutmeg. This béchamel is the heart of your Croque Monsieur Bites: creamy, tangy, and perfectly seasoned.
Step 4: Layer the cheeses and ham in the pastry cups
In a medium bowl, combine shredded Gruyère and Swiss cheese. Spread about a teaspoon of béchamel sauce into each pastry cup bottom. Tear your ham into pieces that fit snugly inside each cup—if your ham is thin, feel free to double the layers for better flavor. Layer ham, then a tablespoon of the cheese mixture, followed by another layer of ham and more cheese. Finally, sprinkle with Parmesan cheese on top for a golden, savory crust. I like to refrigerate the assembled bites for about 10 minutes before baking; this little pause helps the layers settle and reduces any shrinking during baking.
Step 5: Bake until bubbly and golden
Preheat your oven to 400°F (200°C). Bake the croque monsieur bites for 20 to 23 minutes, watching for the pastry to turn a beautiful golden brown and the cheese to be bubbling delightfully. This part is always exciting because your kitchen will fill with that irresistible cheesy aroma. Make sure not to open the oven too often or early, as that might cause the puff pastry to lose its puff.
Step 6: Cool slightly and serve with a fresh finish
Once done, put the muffin pan on a wire rack and let the bites cool for 5 to 10 minutes. This resting time makes them easier to remove and helps the filling settle so it doesn’t spill when you bite in. Use a small offset spatula or dull knife to gently loosen the edges, then carefully lift out each croque monsieur bite. I sprinkle mine with fresh chopped thyme at this stage — it adds a lovely fresh herbal note that ties everything together. Serve these warm to enjoy the perfectly melty cheese and flaky pastry.
Pro Tips for Making Croque Monsieur Bites Recipe
- Don’t skip chilling the dough: Refrigerating the pastry cups before baking prevents shrinking and keeps the shape crisp and tall.
- Warm liquids for béchamel: Pouring warm milk and cream into the roux helps you avoid lumps and makes the sauce silky every time.
- Double up the ham for thin slices: Using two layers of thin deli ham ensures you get a meaty bite with every mouthful.
- Use fresh herbs for garnish: Adding thyme or your favorite fresh herb right before serving brightens flavors and makes it look gorgeous.
How to Serve Croque Monsieur Bites Recipe
Garnishes
When I serve these Croque Monsieur Bites, I love garnishing them with freshly chopped thyme or finely chopped parsley. The herb adds a fresh, aromatic contrast to the rich cheese and ham. Sometimes, a light drizzle of Dijon mustard or a sprinkle of flaky sea salt on top just before serving can send the flavors over the top.
Side Dishes
I typically pair these bites with something crisp and refreshing to offset their richness. A simple green salad tossed with a lemon vinaigrette or a lightly pickled vegetable side does wonders. On occasion, I also serve them alongside a bowl of homemade tomato soup for a cozy, café-style meal that everyone loves.
Creative Ways to Present
For special occasions, I like to arrange these bites on a beautiful wooden board garnished with extra fresh herbs and edible flowers. You can also skewer them with a festive toothpick for easy party serving. Another fun idea is to serve them with small dipping bowls of Dijon mustard or a honey-mustard sauce on the side, letting guests personalize their bites.
Make Ahead and Storage
Storing Leftovers
If you end up with leftovers, place them in an airtight container once fully cooled. I’ve found they keep well in the fridge for up to 2 days without losing their flavor. Before reheating, allow them to come closer to room temperature so they reheat evenly.
Freezing
I’ve successfully frozen these Croque Monsieur Bites after assembling them but before baking. Just wrap the muffin tin tightly with plastic wrap and foil, then freeze. When you’re ready to bake, thaw them overnight in the fridge and bake as usual. This trick saves so much time if you want to prepare in advance for a party!
Reheating
To reheat, I recommend putting the bites in a 350°F oven for about 10 minutes to get the pastry crispy again and the cheese melty. Microwaving makes the pastry a bit soggy, so the oven is your best friend here for maintaining that fresh-baked texture.
FAQs
-
Can I make Croque Monsieur Bites ahead of time?
Absolutely! You can assemble the bites up to a day before and keep them refrigerated until ready to bake. You can also freeze them before baking for longer storage. Just thaw fully before baking to ensure even cooking.
-
What kind of cheese is best for Croque Monsieur Bites?
The classic choice is a mix of Gruyère and Swiss cheese for their meltability and nutty, creamy flavor. Parmesan on top adds a nice crust. Feel free to experiment with cheeses like Emmental or Comté if you want a twist.
-
Can I substitute regular mustard for Dijon in the béchamel?
You can, but Dijon mustard provides a sharper, more complex flavor that complements the other ingredients best. If you use regular mustard, consider using a little less to avoid overpowering the béchamel sauce.
-
How do I prevent the puff pastry from shrinking?
Chilling the pastry cups in the muffin tin before baking is key. Also, avoid over-stretching the pastry squares when lining the pan. Using frozen, well-thawed puff pastry and working quickly help maintain its structure.
-
Can I make Croque Monsieur Bites without puff pastry?
You could try using bread dough or phyllo dough, but puff pastry gives the signature flaky, buttery texture that’s hard to replicate. If you’re in a pinch, thick slices of bread pressed and toasted can make a casual version, but it won’t have quite the same elegance.
Final Thoughts
These Croque Monsieur Bites have a special place in my kitchen and heart because they’re proof that simple ingredients can come together to create something truly comforting and impressive. Every time I serve them, I see faces light up and hear compliments that remind me why cooking is such a joy. I encourage you to try this recipe like you’re inviting a little Parisian café into your home—flaky, cheesy, and deliciously addictive.

Ingredients
Pastry Cups
- Cooking spray
- 1 (14-oz.) sheet frozen puff pastry, thawed
- All-purpose flour, for surface and dusting
- 1 large egg
- 1 tablespoon water
Béchamel Sauce
- 1 tablespoon all-purpose flour
- 1/2 cup whole milk
- 2 tablespoons heavy cream
- 1 tablespoon unsalted butter
- 1 teaspoon Dijon mustard
- 1/4 teaspoon kosher salt
- 1/8 teaspoon freshly ground black pepper
- 1/8 teaspoon ground nutmeg
Fillings and Toppings
- 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
- Chopped fresh thyme, for serving
Instructions
- Prepare the Muffin Tin and Pastry: Grease a standard 12-cup muffin tin with cooking spray. On a lightly floured surface, roll the thawed puff pastry into a 12″ x 10″ rectangle. Cut the pastry into 12 equal squares. Gently stretch one pastry square to slightly enlarge it, then press it into the bottom and up the sides of one prepared muffin cup. Repeat this with the remaining squares. In a small bowl, beat the egg with 1 tablespoon of water to make an egg wash. Brush a thin layer over the pastry dough in the muffin cups. Refrigerate until ready to fill.
- Warm the Milk and Cream: In a small saucepan over medium heat, warm the whole milk and heavy cream together until just heated through, about 2 minutes, then remove from heat.
- Make the Béchamel Sauce: In another small saucepan over medium-low heat, melt the butter. Add 1 tablespoon of flour, stirring constantly, and cook until smooth and lightly toasted, about 2 minutes. Gradually whisk in the warmed milk and cream mixture in a slow, steady stream. Continue whisking constantly until the sauce thickens, about 2 minutes. Remove from heat and stir in Dijon mustard, kosher salt, black pepper, and ground nutmeg.
- Assemble the Bites: In a medium bowl, combine the shredded Gruyère and Swiss cheeses. Spread 1 teaspoon of the béchamel sauce in the bottom of each pastry cup. Tear pieces of deli ham to fit into the bottom of the cup and place over the béchamel. Use two layers of ham if pieces are thin. Add 1 tablespoon of the cheese mixture over the ham, then add another layer of ham, and top with another tablespoon of the cheese. Sprinkle the top with finely grated Parmesan cheese. Refrigerate the assembled cups until cold, about 10 minutes.
- Bake: Preheat the oven to 400°F (200°C). Bake the croque monsieur bites in the preheated oven for 20 to 23 minutes, or until the pastry is golden brown and the cheese is bubbling.
- Cool and Serve: Remove the muffin tin from the oven and place it on a wire rack. Let the bites cool for 5 to 10 minutes. Use a small offset spatula or dull knife to carefully release the pastries from the sides of the muffin cups and transfer them to a serving platter. Garnish with chopped fresh thyme and serve warm.
Notes
- Make sure the puff pastry is fully thawed before rolling for easier handling.
- Using both Gruyère and Swiss cheeses creates a balanced flavor typical of a Croque Monsieur.
- Be careful not to overfill the pastry cups to avoid overflow during baking.
- Fresh thyme adds a subtle herbal note but can be omitted if unavailable.
- Can be prepared ahead by assembling and refrigerating, then baking before serving.
