How to make Croque Monsieur
Prepare Béchamel Sauce
Melt butter in a small saucepan over medium heat.
Add flour and cook, whisking constantly, for about 1 minute.
Slowly add milk while continuing to whisk to avoid lumps.
Bring to a boil, reduce heat, and simmer gently until the sauce thickens, about 5 minutes.
Season with salt, pepper, and nutmeg.
Remove from heat and stir in 1/4 cup Gruyère cheese until melted.
Assemble the Sandwich
Preheat your oven's grill or broiler.
Spread a thin layer of mustard on each slice of bread.
Layer ham and half of the remaining Gruyère cheese on two slices of bread.
Top with the remaining bread slices.
Cook the Sandwich
Heat a non-stick skillet over medium-high heat.
Brush the outside of each sandwich with melted butter.
Cook sandwiches until the bread is golden brown, about 2-3 minutes per side.
Grill with Cheese
Place sandwiches on a baking sheet.
Spoon béchamel sauce over each sandwich and top with remaining Gruyère cheese.
Grill until cheese is bubbly and golden brown, about 5 minutes.
Optional Croque Madame
In a small nonstick pan, fry the eggs to your liking.
Slide a fried egg on top of each sandwich.
