The croque monsieur is a quintessential French café sandwich that combines crispy toasted bread, savory ham, melted cheese, and a creamy béchamel sauce. This indulgent yet simple dish works beautifully because of the contrast between crunchy exterior and gooey, flavorful interior, making it a beloved comfort food for any time of day.
Ingredients
- 8 slices white sandwich bread (preferably slightly stale)
- 4 slices high-quality cooked ham (about 100g)
- 200g Gruyère cheese, grated (or Emmental as a substitute)
- 2 tablespoons unsalted butter (for toasting and béchamel)
- 2 tablespoons all-purpose flour
- 1 1/4 cups (300ml) whole milk, warmed
- 1 teaspoon Dijon mustard (optional, for spreading on bread)
- Salt and freshly ground black pepper, to taste
- Pinch of freshly grated nutmeg
Instructions
- Prepare the béchamel sauce: In a small saucepan, melt 2 tablespoons of butter over medium heat. Once melted, add the flour and whisk continuously for about 2 minutes until it forms a smooth, pale roux without browning.
- Gradually pour in the warmed milk while whisking constantly to avoid lumps. Continue cooking and stirring until the sauce thickens enough to coat the back of a spoon, about 5-7 minutes. Remove from heat and season with salt, pepper, and a pinch of nutmeg. Set aside.
- Preheat your oven’s broiler (grill) to high. Line a baking sheet with parchment paper or lightly grease it.
- Assemble the sandwiches: Spread a thin layer of Dijon mustard on one side of each slice of bread if using. On four slices, layer the ham evenly, then sprinkle about half of the grated Gruyère over the ham.
- Top each with the remaining bread slices, mustard side down, to form sandwiches.
- Lightly toast the sandwiches: Heat a skillet over medium heat and melt a small amount of butter. Place the sandwiches in the skillet and cook for 2-3 minutes on each side until golden brown but not fully cooked through. This step helps achieve a crisp crust.
- Transfer the sandwiches to the baking sheet. Spoon a generous amount of béchamel sauce evenly over the top of each sandwich, then sprinkle the remaining Gruyère cheese on top.
- Broil until bubbly and golden: Place the baking sheet under the broiler for 3-5 minutes, watching carefully, until the cheese is melted, bubbly, and lightly browned.
- Remove from oven and let rest for a minute before serving. This allows the béchamel to set slightly and prevents burns.
Tips
- Cheese substitutions: Gruyère is traditional for its nutty flavor and good melting qualities, but Emmental or Comté can work well as alternatives.
- Using day-old bread: Slightly stale bread crisps up better and holds the béchamel sauce without becoming soggy.
- Béchamel texture: Make sure to whisk constantly when adding milk to avoid lumps and cook until thickened enough to coat the back of a spoon.
- Broiling caution: Keep a close eye during broiling; cheese can go from perfectly browned to burnt in seconds.
Serving Suggestions
Serve your croque monsieur with a simple green salad dressed lightly with vinaigrette to balance the richness of the sandwich. A crisp cucumber salad or lightly pickled vegetables also complement it well. For a heartier meal, pair with a bowl of French onion soup or a glass of dry white wine such as Sauvignon Blanc or a light Pinot Noir.
Variations
Croque Madame: The classic variation topped with a fried or poached egg adds richness and makes the dish even more filling. Place the cooked egg on top right after broiling.
Vegetarian option: Replace the ham with grilled or sautéed mushrooms, spinach, or roasted red peppers. Use a vegetarian béchamel (made with vegetable stock) and cheese if desired.
Different breads: While traditional recipes use white sandwich bread, you can experiment with brioche for a sweeter touch or sourdough for a tangier flavor and firmer texture.
Storage and Reheating
Store leftover croque monsieur in an airtight container in the refrigerator for up to 2 days. To reheat, place the sandwich on a baking sheet and warm in a preheated oven at 350°F (175°C) for about 10-12 minutes until heated through and the cheese is melty again. Avoid microwaving as it can make the bread soggy.
Frequently Asked Questions
Can I make the béchamel sauce ahead of time?
Yes, you can prepare the béchamel sauce a day ahead and store it in the refrigerator. Reheat gently on the stove with a splash of milk to loosen it before assembling the sandwiches.
What type of ham is best for croque monsieur?
Use a high-quality cooked ham, such as Parisian ham or any thinly sliced deli ham with good flavor and texture. Avoid overly salty or dry hams to keep the sandwich balanced.
Is it necessary to use béchamel sauce?
While béchamel is traditional and adds creaminess, some recipes skip it and just use mustard and cheese. However, the sauce helps bind the sandwich and creates the signature richness of a croque monsieur.
Can I use gluten-free bread or flour?
Yes, gluten-free bread can be used, though texture and crispness may vary. For béchamel, substitute all-purpose flour with a gluten-free blend or cornstarch (use half the amount). Adjust thickening as needed.
How do I prevent soggy bread?
To avoid sogginess, toast the bread lightly before assembling and avoid soaking it in béchamel. Also, broil the sandwich just before serving to keep the crust crisp.
What wine pairs well with croque monsieur?
A dry white wine like Sauvignon Blanc or a light red such as Pinot Noir complements the rich cheese and ham flavors without overpowering the dish.
Enjoy crafting this classic French comfort food that’s perfect for lunch, brunch, or a cozy dinner. Its balance of textures and flavors makes croque monsieur a timeless favorite that’s surprisingly easy to master at home.
