How to Make Irresistible Croque Monsieur
-
Melt Butter: In a saucepan over medium heat, melt 3 tablespoons of unsalted butter. This will form a beautiful base for your béchamel sauce.
-
Whisk Flour: Add 1/4 cup of plain flour to the melted butter and whisk to create a roux, cooking for about 1-2 minutes until it bubbles lightly without browning.
-
Pour Milk and Cream: Gradually whisk in 1 cup of milk and 1/2 cup of cream. Keep stirring until the sauce thickens, which should take around 5-7 minutes. It should be creamy and smooth.
-
Season Sauce: Sprinkle in 1/2 teaspoon of salt, 1/4 teaspoon of white pepper, and 1/4 teaspoon of nutmeg, then remove the saucepan from heat. The sauce will be rich and flavorful!
-
Preheat Skillet: Get your skillet ready by preheating it over medium heat. Add 2 tablespoons of unsalted butter, allowing it to melt until it just starts to foam.
-
Spread Mustard: On one side of each slice of sourdough bread, spread 2 tablespoons of Dijon mustard. This will add a lovely zing to your sandwich!
-
Assemble Sandwiches: Layer 4 slices of Swiss or Gruyere cheese and 4 slices of ham on the unbuttered side of two slices of bread. Top with the other slices, mustard side down, pressing them gently together.
-
Cook Sandwiches: Place the sandwiches into the skillet and cook until both sides are golden brown and the cheese is melt-in-your-mouth gooey, about 3-4 minutes per side.
-
Top with Cheese: Remove the sandwiches from the skillet and place them on a baking sheet. Generously sprinkle 1 cup of shredded Gruyere cheese and 1/4 cup of grated Parmesan on top.
-
Broil: Pop the baking sheet under the broiler for about 2-3 minutes, just until the cheese is bubbly and golden. Watch closely—it should be perfection!

Make Ahead Options
These Irresistible Croque Monsieur sandwiches are a fantastic choice for meal prep, allowing you to enjoy their deliciousness even on your busiest days! You can prepare the béchamel sauce up to 3 days ahead; simply refrigerate it in an airtight container. To maintain quality and prevent the sauce from thickening too much, reheat it gently on the stovetop, adding a splash of milk if needed. You can also assemble the sandwiches without cooking them and wrap them tightly in plastic wrap, refrigerating for up to 24 hours. When you’re ready to serve, just cook them in the skillet until golden and melt the cheese under the broiler for that wonderfully bubbly finish. With these prep tasks done ahead of time, you’ll have a restaurant-quality meal with minimal effort!

Chef's Helpful Tips

- Keep an eye on the cooking time in the skillet; aim for 3-4 minutes per side until the sandwiches are golden brown and the cheese is perfectly melted.
