How to Make Savory Croque Monsieur Recipe Easy Homemade French Ham & Cheese Sandwich
- Preheat your oven to 400°F and line a baking sheet with parchment paper.
- Make the béchamel sauce: melt 2 tablespoons butter in a saucepan over medium heat. Whisk in flour and cook for 1-2 minutes until slightly golden. Gradually whisk in warm milk, stirring constantly until the sauce thickens, about 5 minutes. Remove from heat and stir in Dijon mustard, nutmeg, salt, and pepper.
- Spread a thin layer of béchamel sauce on one side of each bread slice. On four slices, layer ham and half of the shredded Gruyère cheese. Top with the remaining bread slices, béchamel side down, to form sandwiches.
- Place sandwiches on the baking sheet. Spread a thin layer of butter on the top of each sandwich, then evenly spoon the remaining béchamel sauce on top. Sprinkle the remaining Gruyère cheese over the béchamel.
- Bake in the preheated oven for 10-12 minutes until the cheese is melted and bubbly. For a golden, crispy top, switch to broil for an additional 2-3 minutes—watch carefully to avoid burning.
- Remove from the oven and let the sandwiches cool for a couple of minutes. Garnish with chopped parsley if desired, then slice and serve warm.
Tips for the Best Results
- Use day-old or slightly stale bread for better toasting and texture.
- Warm the milk before adding to the roux to prevent lumps in your béchamel.
- Keep an eye on the broiler step to prevent the cheese from burning quickly.
- Gruyère is traditional, but Emmental or Swiss cheese can be great substitutes.
- For extra richness, add a thin slice of Parmesan on top before broiling.
Storage and Reheating
Store leftover croque monsieur sandwiches wrapped tightly in foil or an airtight container in the refrigerator for up to 2 days. To freeze, wrap each sandwich individually and place in a freezer-safe bag for up to 1 month.
Reheat refrigerated or thawed sandwiches in a 350°F oven for 10-15 minutes until warmed through and crispy. Avoid microwaving to keep the bread from becoming soggy.
Frequently Asked Questions
Can I use a different type of bread?
Yes, you can use brioche or sourdough bread for a richer or tangier flavor. Just make sure the slices aren’t too thick to allow for even melting and toasting.
What can I substitute for Gruyère cheese?
Emmental, Swiss, or even a mild cheddar can work well. These cheeses melt nicely and complement the ham and béchamel sauce.
Is there a vegetarian version of croque monsieur?
Absolutely! You can omit the ham and add sautéed mushrooms or roasted vegetables for a delicious croque madame alternative, which traditionally also includes a fried egg on top.
Can I make the béchamel sauce ahead of time?
Yes, you can prepare the béchamel sauce a day in advance. Store it in an airtight container in the fridge and gently reheat while stirring before using it in the recipe.
