How to Make a Croque Monsieur: Step-by-Step Instructions
Step 1: Craft the Béchamel Sauce
The béchamel sauce is the key element of a Croque Monsieur, providing its rich and creamy texture. Follow these steps:
- Melt the butter in a small saucepan over medium heat.
- Gradually incorporate the flour, whisking constantly until it forms a smooth, golden roux.
- Slowly add the milk, continuing to whisk until the mixture is smooth and thickened.
- Enhance the flavor by seasoning with salt, black pepper, and a touch of nutmeg. Set aside to cool slightly.
Step 2: Build Your Sandwich
- Spread a thin layer of béchamel sauce on one side of each slice of bread.
- Add a slice of ham and a generous amount of grated Gruyère cheese to two slices.
- Top with the remaining bread, béchamel side down.
Step 3: Toast and Broil
- Melt butter in a skillet over medium heat. Place the sandwiches in the pan and cook until the bread turns golden and crispy, about 2–3 minutes per side.
- Transfer the sandwiches to a baking sheet, spread béchamel on top, and sprinkle with more cheese.
- Place it under the broiler for a few minutes until the cheese melts and develops a golden, bubbly crust.
Creative Variations of Croque Monsieur
Croque Madame
For a richer variation, add a fried or poached egg on top. The runny yolk enhances the sandwich’s creamy texture and makes it even more decadent.
Regional Twists
- Croque Provençal: Add slices of fresh tomato for a hint of brightness.
- Croque Norvégien: Swap out the ham for smoked salmon for a seafood-inspired twist.
- Vegetarian Croque: Replace the ham with sautéed mushrooms or roasted vegetables for a plant-based option.
Pro Tips for Perfecting Your Croque Monsieur
- Use quality bread: Day-old brioche or sourdough holds up better during cooking and provides excellent texture.
- Grate your cheese finely: This ensures even melting and a smoother finish.
- Don’t skip the béchamel: It’s the key to achieving a creamy, flavorful sandwich.
