8 ozquality thinly sliced ham
6 ozGruyère cheese, freshly grated

Béchamel

2 tbspunsalted butter
2 tbspall-purpose flour
1 cupwhole milk, room temperature
salt and white pepper to taste
freshly grated nutmeg(optional)

Instructions

Set your broiler to high and position a rack about 6 inches from the heat source. You'll want everything ready to go once you assemble these beauties.
Melt the butter in a heavy-bottomed saucepan over medium heat, letting it foam and settle without browning. This forms the foundation of your béchamel.
⏱ 1 min
Whisk the flour into the melted butter, stirring constantly until it forms a smooth, pale paste that doesn't smell raw anymore. This roux needs to cook properly or your sauce will taste floury.
⏱ 2 min
Pour in the milk gradually while whisking continuously — this prevents lumps from forming. Keep stirring and cooking until the sauce coats the back of a spoon and has lost any chalky flour taste.
⏱ 5 min
Remove the béchamel from heat and season with salt, white pepper, and a whisper of nutmeg if using. The sauce should taste creamy and well-balanced, not bland.
Toast the bread slices in a toaster or under the broiler until they're just golden on both surfaces. You want them sturdy enough to support the toppings but not so crispy they'll shatter.
⏱ 3 min
Build your sandwiches by layering the ham and half the grated Gruyère on 4 bread slices, then crown with the remaining bread. Press gently so everything holds together.
Spread the warm béchamel evenly across the top of each sandwich, then shower with the remaining Gruyère. Don't skimp — this cheese layer creates that gorgeous golden top.
Slide under the broiler and watch carefully until the tops are deeply golden and bubbling around the edges. The cheese should be melted through and the béchamel lightly browned.
