Perfect for a quick yet luxurious lunch, a light dinner, or even a show-stopping brunch, this mushroom croque-monsieur is a versatile delight that will appeal to cheese lovers, mushroom enthusiasts, and anyone seeking a moment of pure culinary comfort.
History and Origin of the Croque-Monsieur
To truly appreciate this gourmet twist, we must first look back at the history of its predecessor, the classic Croque-Monsieur. This iconic French dish first appeared on the menu of a Parisian café on the Boulevard des Capucines in 1910 . Its name is wonderfully literal, derived from the French words “croquer” (to crunch) and “monsieur” (mister), perfectly describing a crispy snack for a gentleman.
The exact origin story is often debated, but it is widely believed that the croque-monsieur was a simple, ingenious creation by Parisian bistros to use up leftover bread, ham, and cheese. Its popularity skyrocketed due to its incredible flavor and ease of preparation, quickly becoming a staple in brasseries and cafés across France . The first known recipe appeared in 1918 in Volume 2 of “Le Poids Idéal” by Monsieur Bourgain, recommending a béchamel sauce to elevate the sandwich to new heights of creaminess. Over a century later, it remains a beloved classic, constantly reinvented by chefs and home cooks alike, with our mushroom version being a prime example of its enduring appeal.
Ingredients
This recipe is designed for two generous servings. The quality of each ingredient is paramount to the final dish’s success .
For the Sandwiches:
· 4 slices of quality bread: Opt for pain de mie, brioche, or a sturdy country loaf. Slightly thicker slices (about 1.5 cm or 0.6 inches) work best to hold the generous filling .
· 2 slices of ham (approx. 60g): Traditional French recipes use Paris ham (jambon de Paris). You can also use chicken ham for a lighter flavor or smoked ham for a deeper, more robust taste .
· 200g fresh mushrooms: Common button mushrooms (champignons de Paris) are a classic choice, but feel free to use a mix of cremini, portobello, or even fresh porcini for a more intense, forest-like flavor .
For the Béchamel Sauce:
· 30g unsalted butter + extra for greasing: The base of the sauce and for achieving a golden crust .
· 30g all-purpose flour: To thicken the béchamel .
· 300ml whole milk: Provides the richest and creamiest texture .
· Salt, to taste.
· Freshly ground black pepper, to taste.
· A generous pinch of ground nutmeg: An essential spice that adds warmth and depth to the béchamel .
For the Finishing Touch:
· 100g grated cheese: Gruyère or Emmental are the traditional choices for their excellent melting qualities and nutty flavor. A mix of both is even better .
Formation (Step-by-Step Assembly & Methods)
Follow these steps to build the perfect mushroom croque-monsieur. You have two primary methods for the final cooking: the classic oven bake or a quicker stovetop sear.
Phase 1: The Preparations
1. Prepare the Mushrooms: Gently clean the mushrooms with a damp paper towel or a soft brush—never wash them under running water, as they act like sponges and will become soggy . Slice them finely.
2. Sauté the Mushrooms: In a skillet or frying pan, heat a small knob of butter or a drizzle of olive oil over medium heat . Add the sliced mushrooms and a pinch of salt. Sauté for about 5-7 minutes, until they have released their moisture, turned golden brown, and are tender. Set aside .
Phase 2: The Béchamel Sauce
1. Make the Roux: In a small saucepan, melt the 30g of butter over medium heat. Once foaming, add the flour all at once. Whisk vigorously and continuously for about 1-2 minutes. This cooks the raw flour taste but without letting it brown; you want a pale, foamy paste called a roux .
2. Incorporate the Milk: Gradually pour in the cold milk, a little at a time, while whisking constantly. This is the key to a smooth, lump-free sauce . Continue whisking until all the milk is incorporated.
3. Thicken and Season: Bring the sauce to a gentle simmer. It will thicken as it heats. Let it bubble gently for 2-3 minutes, stirring occasionally, until it reaches a creamy, nappé consistency (coating the back of a spoon).
4. Final Touch: Remove the pan from the heat. Season with salt, pepper, and a generous grating of fresh nutmeg. For this gourmet version, stir the sautéed mushrooms directly into the béchamel, or reserve them to layer separately for more texture .
Phase 3: Assembly and Cooking
Method 1: The Classic Oven-Baked Croque (for a perfectly gratinéed top)
1. Preheat & Prep: Preheat your oven to 200°C (392°F) . Lightly butter one side of each bread slice.
2. First Layer: Place two slices of bread, buttered side down, on a baking sheet lined with parchment paper.
3. Build: Spread a small spoonful of béchamel on each slice. Top with a slice of ham, folding it to fit. Distribute the sautéed mushrooms (if not already in the sauce) over the ham. Sprinkle with a generous amount of grated cheese.
4. Top It Off: Place the remaining two slices of bread on top, buttered side up.
5. The Crown: Spread the remaining béchamel sauce over the top of each sandwich, ensuring it covers the bread completely. Sprinkle liberally with the remaining grated cheese .
6. Bake: Bake for 15-20 minutes, or until the top is golden brown, bubbly, and the sandwiches are heated through. For an even more gratined crust, you can switch on the broiler (grill) for the last 1-2 minutes .
Method 2: The Stovetop Method (for a quicker, crispier exterior)
1. Assemble: Spread a thin layer of béchamel on the inside of all four bread slices. On two of the slices, layer the ham, the sautéed mushrooms, and a generous amount of cheese. Top with the remaining two bread slices, béchamel-side in .
2. Butter the Pan: Melt a knob of butter in a large non-stick skillet over medium-low heat.
3. Sear: Carefully place the sandwiches in the pan. To get that classic, flat, and evenly golden crust, place another heavy pan or a cast-iron press directly on top of the sandwiches . Cook for 3-4 minutes per side, until the bread is deeply golden and crisp, and the cheese has melted inside.
4. Serve Immediately: This method is faster and yields an incredibly crunchy exterior.
