This is one spiffied up grilled cheese sandwich! I have wanted to make croque monsieur sandwiches ever since I had one in a quaint little bistro in downtown Chicago several years ago but they seemed too complicated and not worth the effort. Despite those fears, I decided to make them for my family the other night. They were fantastic and SO simple! It took the “make-dinner-fast” issue that usually results in plain old grilled cheese to a whole new level. They were unique, the cheese was creamy both inside and out (thanks to the mayonnaise layer) and they were altogether delicious.
2 tablespoons mayonnaise
¾ teaspoon Dijon mustard
8 slices white bread
4 thin slices ham
8 thin slices Gruyere cheese (I used swiss)
2 tablespoons unsalted butter, melted
In a small bowl stir together 1 tablespoon of the mayo and the mustard. Spread evenly over 4 slices of the bread. Arrange a slice of ham and a slice of Gruyere on each piece of bread.
Put the remaining 4 slices of bread on top of the sandwiches. Brush the outside of both slices of bread with the melted butter. Preheat an indoor grill or heat a nonstick grill pan over medium-high heat.
Grill for 2 to 3 minutes on each side or until the bread is lightly browned on both sides and there are nice-looking grill marks on the bread. Using a large spatula, transfer the sandwiches to a broiling tray or cookie sheet. Preheat the broiler.
Spread the top of the sandwiches with the remaining tablespoon mayo and top with the 4 remaining slices cheese, being sure to cover the crusts of the bread.
Broil, cheese side up, for 1 to 2 minutes, or until bubbly and golden brown. Serve hot.
Makes 4 sandwiches.
