How to Make Croque Monsieur Bites
-
Preheat oven: Set your oven to 400˚F (200˚C) and lightly spray a muffin tin with cooking spray to ensure easy removal of your Croque Monsieur Bites later.
-
Prepare pastry: On a lightly floured surface, roll out the thawed puff pastry into a 12×12-inch square. This creates the perfect base for your delicious bites.
-
Cut and chill: Using a sharp knife, cut the pastry into 12 rectangles. Place each rectangle into a muffin tin cup and refrigerate while you prepare the béchamel.
-
Make béchamel sauce: In a small saucepan, heat the unsalted butter over medium heat until it becomes foamy. Then, reduce the heat to low, add the flour, and whisk for about one minute until smooth and bubbly.
-
Combine ingredients: Gradually stream in the whole milk while whisking, ensuring no lumps remain. Blend in the Dijon mustard, salt, nutmeg, and black pepper, then continue to whisk over medium-low heat for around 3 minutes until the sauce thickens enough to coat the back of a spoon. Allow to cool slightly.
-
Assemble the bites: In each pastry-lined muffin cup, spread 1 teaspoon of béchamel at the bottom. Layer in the diced ham, followed by the shredded cheeses—gruyere, Swiss, and parmesan. Spoon another teaspoon of the béchamel on top and sprinkle with fresh thyme for that herby note.
-
Bake: Place the muffin tin in the oven and bake for 22-24 minutes. Look for golden brown edges and bubbling cheese, which signals they’re done. Let them cool for 10 minutes before serving to allow flavors to meld.
Optional: Garnish with extra thyme sprigs for a fresh presentation.

Croque Monsieur Bites Variations

Expert Tips for Croque Monsieur Bites
-
Chill the Pastry: Refrigerate the puff pastry after placing it in the muffin tin. This helps maintain its flakiness during baking, ensuring perfectly puffed bites.
-
Avoid Lumps: When making the béchamel, add the milk slowly while whisking continuously. This prevents lumps from forming and results in a smooth sauce.
-
Layer with Care: Don’t overstuff the bites. Keep the layers of ham and cheese moderate to ensure even cooking and prevent overflow during baking.
-
Watch the Bake Time: Ovens may vary in temperature, so keep an eye on your Croque Monsieur Bites. Remove them when the cheese is golden brown and bubbling for the best texture.
-
Use Fresh Ingredients: Opt for fresh thyme and high-quality cheeses for the most flavorful experience. Fresh ingredients can make a noticeable difference in taste.
