- Cheese:
- 1 ½ cups (about 150g) grated aged Gruyère cheese
- Béchamel Sauce:

- 2 tablespoons all-purpose flour
- 1 ¼ cups (300ml) whole milk
- 1 teaspoon Dijon mustard (optional)
- A pinch freshly grated nutmeg
- Salt and pepper to taste

How to Make Croque Monsieur
-
Make the Béchamel Sauce:
- In a small saucepan over medium heat, melt 2 tablespoons of butter. Whisk in 2 tablespoons of flour and cook for 1-2 minutes without allowing it to brown.
- Gradually add 1 ¼ cups of whole milk while whisking to prevent lumps. Continue whisking until the sauce thickens and coats the back of a spoon, about 5 minutes. Season with salt, pepper, and nutmeg. Remove from heat and stir in the Dijon mustard if using.
-
Prepare the Bread and Fillings:
- Lay out the 8 slices of bread. Spread a thin layer of béchamel on one side of each slice. On four of the slices, layer 1-2 slices of ham and sprinkle about ½ cup of grated Gruyère cheese. Top with the remaining slices of bread, béchamel side down, to form sandwiches.
-
Butter the Sandwiches:
- Spread the remaining 1 tablespoon of softened butter on the outside of each sandwich, both top and bottom.
-
Cook the Sandwiches:
- Heat a non-stick skillet over medium heat. Cook the sandwiches for 3-4 minutes on each side, pressing gently with a spatula, until a deep golden crust forms and the cheese begins to melt.
-
Finish with Cheese Topping (Optional):
- Spoon extra béchamel on top of each sandwich, sprinkle with the remaining grated Gruyère, and place under the broiler or in a 400°F oven for 2-3 minutes until bubbly and golden brown.
-
Serve Warm:
- Allow sandwiches to cool for 1-2 minutes before slicing to let the cheese set slightly.
Tips for Success
- Ensure the butter is softened for easy spreading on the bread.
- Cook the béchamel sauce carefully, whisking constantly to avoid lumps.
- Press the sandwiches gently while cooking to help them brown evenly.
- Allowing the sandwiches to cool slightly after cooking helps the cheese set and makes them easier to slice.
Easy Variations
- Vegetarian Option: Replace the ham with sautéed mushrooms or spinach for a delicious meat-free version.
- Different Cheeses: Experiment with different cheeses like cheddar, mozzarella, or a spicy pepper jack for a unique twist.
- Herbed Béchamel: Add fresh or dried herbs, such as thyme or rosemary, to the béchamel for extra flavor.
- Make it Croque Madame: Add a fried egg on top of each sandwich for a delightful breakfast version.
- Spicy Kick: Incorporate sliced jalapeños or a dash of hot sauce into the sandwich for some heat.
What to Serve with Croque Monsieur
- Mixed Green Salad: A light salad provides a refreshing contrast to the richness of the sandwich.
- French Fries: Crispy fries pair wonderfully, bringing a classic bistro vibe to your meal.
- Tomato Soup: This comforting combo is a nostalgic favorite that complements the savory flavors perfectly.
- Pickles: Tangy pickles add a nice crunch and balance the richness of the cheese and ham.
Storage and Reheating
- Refrigerator Storage: Store leftover sandwiches in an airtight container in the refrigerator for up to 3 days.
- Freezer Storage: You can freeze ungrilled sandwiches for up to 2 months. Wrap each sandwich tightly and follow the cooking instructions from frozen, adding a few extra minutes to the cooking time.
- Best Reheating Method: Reheat in a skillet over medium-low heat to retain the crispness of the bread, or in an oven at 350°F until warmed through.
- Preserve Texture: Avoid microwaving, as it can make the bread soggy.
Common Mistakes to Avoid
- Using Cold Bread or Ingredients: Bring bread and cheese to room temperature for even cooking and melting.
- Not Whisking the Béchamel: Ensure continuous whisking while adding milk to avoid lumps in your sauce.
- Overcrowding the Pan: Cook sandwiches in batches if necessary, allowing enough space for even cooking.
- Skipping the Butter on the Outside: Buttering the bread creates a golden crust that enhances flavor and texture.
