The croque monsieur is a quintessential French café sandwich combining toasted bread, ham, melted cheese, and a luscious béchamel sauce. Its rich, creamy texture paired with the crisp, golden exterior makes it a perfect comfort meal that’s easy to recreate at home—even when you’re craving that “croque monsieur near me” experience.
Ingredients
- 8 slices white sandwich bread (preferably a sturdy type like pain de mie)
- 4 slices cooked ham (about 100g total)
- 150g Gruyère cheese, grated (or Emmental as a substitute)
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 1/4 cups (300ml) whole milk, warmed
- 1 teaspoon Dijon mustard
- Salt and freshly ground black pepper, to taste
- Pinch of grated nutmeg
- Optional: 1 tablespoon grated Parmesan cheese (for topping)
Instructions
- Prepare the béchamel sauce: In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for about 2 minutes, stirring constantly, to form a roux without browning it.
- Gradually add the warmed milk in a slow, steady stream while whisking continuously to avoid lumps. Continue cooking and stirring until the sauce thickens and coats the back of a spoon, about 5-7 minutes.
- Remove from heat, then stir in the Dijon mustard, a pinch of nutmeg, salt, and pepper. Set aside about half of the béchamel sauce for spreading on the bread, and reserve the rest for topping.
- Assemble the sandwiches: Preheat your oven to 425°F (220°C). Lay out 4 slices of bread on a baking sheet or ovenproof dish. Spread a thin layer of béchamel sauce on each slice.
- Place a slice of ham on each béchamel-coated bread slice, then sprinkle evenly with about two-thirds of the grated Gruyère cheese.
- Top with the remaining 4 slices of bread. Spread the reserved béchamel sauce over the top of each sandwich, then sprinkle with the remaining Gruyère and, if using, the Parmesan cheese.
- Bake: Place the baking sheet in the oven and bake for 10-12 minutes until the cheese topping is bubbling and golden brown.
- For an extra crisp finish, switch the oven to broil (grill) and broil the sandwiches for 1-2 minutes, watching carefully to prevent burning.
- Remove from oven and let cool for a minute before serving.
Tips
- Cheese substitutions: If Gruyère isn’t available, Emmental or a good-quality Swiss cheese works well. Avoid pre-shredded cheese as it often contains anti-caking agents which can affect melting.
- Bread choice: Use thick, sturdy slices like pain de mie or a slightly dense white bread. Thin or soft bread can become soggy under béchamel.
- Make béchamel ahead: The sauce can be made a day in advance and refrigerated. Reheat gently with a splash of milk to loosen before assembling.
- Avoid sogginess: Toast the bread lightly before assembling if you prefer a firmer texture inside the sandwich.
Serving Suggestions
A croque monsieur pairs beautifully with a simple green salad dressed with a light vinaigrette to cut through the richness. Classic French sides include a small bowl of cornichons (tiny pickles) or a handful of mixed olives. For a heartier meal, serve with a cup of hot French onion soup or a crisp apple cider.
Variations
The classic croque monsieur can be easily adapted. Add a fried or poached egg on top to transform it into a croque madame. For a vegetarian option, swap the ham for sautéed mushrooms or grilled zucchini. You can also experiment with different cheeses, such as adding a bit of blue cheese for a sharper bite, or incorporate herbs like thyme into the béchamel for added aroma.
Storage and Reheating
Store any leftover croque monsieur wrapped tightly in plastic wrap or 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 350°F (175°C) oven for 10-15 minutes until heated through and the cheese is melted again. Avoid microwaving as it can make the bread soggy.
Frequently Asked Questions
What is the difference between a croque monsieur and a grilled cheese?
A croque monsieur is a French sandwich made with ham, Gruyère cheese, and a creamy béchamel sauce, then baked or broiled until golden. Grilled cheese is simpler, typically just bread and melted cheese cooked in a skillet without béchamel or ham.
Can I make croque monsieur without béchamel sauce?
While béchamel is traditional and adds creaminess, you can make a simpler version by layering cheese and ham between bread and grilling it. However, béchamel is key to the authentic texture and flavor.
What type of cheese works best?
Gruyère is classic for its nutty, slightly sweet flavor and excellent melting properties. Emmental or Swiss cheese are good substitutes. Avoid cheeses that don’t melt well or have overpowering flavors.
How do I prevent the sandwich from getting soggy?
Use sturdy bread, toast it lightly beforehand, and spread béchamel sparingly on the bread. Baking at a high temperature helps create a crisp crust that contrasts nicely with the creamy inside.
Can I prepare croque monsieur in advance?
Yes, you can assemble the sandwiches and refrigerate them for a few hours before baking. If making the béchamel ahead, reheat gently before assembling. Baking fresh yields the best texture.
Is croque monsieur gluten-free?
Traditional croque monsieur uses wheat bread and flour in béchamel, so it is not gluten-free. To make a gluten-free version, use gluten-free bread and substitute the flour in béchamel with a gluten-free thickener like cornstarch or rice flour.
The croque monsieur remains a beloved French classic thanks to its balance of textures and flavors. With this recipe, you can easily recreate that “near me” café quality at home with simple ingredients and straightforward steps. Bon appétit!
