Give your next ham and cheese sandwich a touch of je ne sais pas: Make it a Croque Monsieur. What sets this Parisian delight apart? First, it's got gooey dairy goodness on the inside as well as the outside, thanks to béchamel sauce, another French creation. Our recipe incorporates the brightness of Dijon mustard, which contrasts with the nutty-salty flavors from Gruyère and ham. When these rich elements are propped up by the light crunch of toasted white bread, c'est un vrai délice.
How to Make A Sheet Pan Croque Monsieur Sandwich Recipe
This simple Croque Monsieur recipe is a baked take on the traditional French café classic, made with toasted slices of sturdy white bread—like country or sourdough—filled with sliced ham, creamy béchamel sauce, and topped with plenty of shredded Gruyère cheese. Béchamel, a classic French white sauce made from butter, flour, and milk, adds richness and helps create that perfectly melty, golden top when broiled. To make the perfect Croque Monsieur, toast the bread first to prevent sogginess, layer generously, and finish under the broiler for a crisp, bubbling finish. While a Croque Monsieur is made with ham and cheese, a Croque Madame includes a fried egg on top. Serve your sandwich with a fresh green salad, roasted vegetables, or even a light soup for a complete and satisfying meal. Whether you're new to baked sandwich recipes or looking for the best bread and cheese combo for a Croque Monsieur sandwich, this version delivers comfort and flavor in every bite.

Heat oven to 350° F. Arrange four slices of bread on a quarter sheet tray and place in the oven for 10 minutes, flipping halfway through baking time, until toasted and golden on both sides. Remove from the oven.
Meanwhile, make the béchamel sauce by melting butter in a saucepan over medium heat. Whisk in flour and cook, stirring constantly, for about 2 minutes. Gradually add milk, stirring well until the mixture is smooth. Cook, stirring, until sauce thickens. Whisk in mustard and black pepper and remove from heat.
To assemble the Croque Monsieur sandwiches, top each of the bread slices with a layer of béchamel, spreading it all the way to the edges. Arrange two of the bread slices on the baking sheet. Top each with ham and a handful of shredded cheese. Place remaining slices of bread on top, béchamel side up, then top with remaining cheese.
Bake at 350° F for about 10 minutes, until cheese is melted, and then turn the oven to broil and broil until the cheese on top is lightly golden, about 2 minutes. Remove Croque Monsieur sandwiches from the oven and sprinkle with fresh thyme leaves (optional) before serving.
