The croque-monsieur is a classic French grilled cheese sandwich that's a mainstay of Parisian cafes, bars, and bistros, not to mention innumerable take-out counters.

Served with a side of French fries and a little pile of salad greens, a Croque-Monsieur is everything that's great about eating in Paris—even their snacks are somehow sublime and otherworldly.

Combining a creamy béchamel sauce with nutty Gruyère cheese, the croque-monsieur is grilled cheese perfection. Keep in mind that most places that serve Croque-Monsieurs have stacks of the things made ahead of time, and they'll warm one up for you when you order it. And yet they're still delicious.

The recipe that follows will make one sandwich, but you can double it to make two. You can substitute Jarlsberg or even Monterey Jack for the Gruyère.

In case you were wondering, croque-monsieur translates literally to "Mr. Crunch." Best name for a sandwich ever.

  6. Divide the cheese mixture in half. Spoon half the cheese mixture onto one slice of bread (on the mustard side, not the butter side), and spread it evenly. Lay the sliced ham atop the other slice.

  8. Spray a bit of cooking spray onto the surface of a nonstick pan. Heat the pan over medium heat until the oil is hot and glistening but not quite smoking.

  9. Place the sandwich into the pan and cook for about 2 minutes, or until the bottom of the bread is a nice shade of golden-brown.

  10. Use a nonstick spatula to flip the croque-monsieur over. Lower the heat a bit and cover the pan. Cook for another minute or two, or until the second slice of bread is also golden brown, and the cheese inside the croque-monsieur is fully melted.

Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat resistant, tempered glass products can, and do, break occasionally.

Recipe Variations

  • Muenster, Gouda, Fontina, and Comté are good to use instead of or in combination with the Gruyère.
  • Substitute sliced cooked chicken breast for ham.
  • Instead of white bread, use sourdough. Leave crusts on.
  • Top finished sandwich with a fried egg to make a croque madame, possibly named because the egg resembles a ladies' hat.

Raw Egg Warning

Consuming raw and lightly cooked eggs poses a risk of foodborne illness.
