2 tablespoons flour
1 cup milk

Instructions

Preheat the oven to 375F and generously grease a 24-cup mini muffin tin.
Roll the puff pastry sheet out to a 10x15 inch rectangle and cut it into 24 equal 2.5 inch squares. Fit each puff pastry square into the cups of the mini muffin tin.
Brush the insides of each puff pastry cup with a little Dijon mustard. Place the pan in the fridge to chill while you prepare the béchamel.
In a small saucepan, melt the butter over medium heat. Add the onion and cook until softened and translucent, about 2 minutes.
Sprinkle in the flour and cook, whisking continuously, for one minute. Slowly add the milk while whisking. Keep whisking until the sauce begins to bubble and thicken, about 3-4 minutes.
Remove the pan from the heat and whisk in the nutmeg, salt and pepper.
Divide the ham equally between the puff pastry cups. Top with a teaspoon of béchamel sauce, and sprinkle with cheese.
Transfer the pan to the preheated oven and bake for 20-22 minutes, until the cheese is browned and bubbling and the puff pastry is golden.
Garnish with a little fresh thyme and let cool 5-10 minutes before serving.

Notes

Storage and Reheating

Let the mini croque monsieurs cool completely at room temperature and store in the fridge in an airtight container in a single layer for 3-4 days. These will also freeze very well for up to 3 months.

Reheat in an oven preheated to 350°F for about 5-10 minutes, or until they're thoroughly warmed and the pastry has crisped back up. Avoid using the microwave, as it tends to make the pastry soft.
