Introduction
There’s a reason the Croque Monsieur has stood the test of time in French cafés and households—it’s indulgent, elegant, and deeply comforting. Imagine biting into crisp, golden toast filled with layers of savory ham and melted cheese, all topped with a rich béchamel sauce and more cheese broiled to bubbling perfection. It’s simple yet sophisticated.
The name Croque Monsieur loosely translates to “Mister Crunch,” and it lives up to that name with every bite. This recipe embodies the beauty of classic French cuisine: minimal ingredients treated with care and technique, producing flavor that feels luxurious.
Let’s explore the history, method, and artistry behind making the perfect Croque Monsieur.
📜 Origins of the Croque Monsieur
The Croque Monsieur first appeared on French café menus around 1910, though some culinary historians believe versions of it existed even earlier. A staple of Parisian brasseries, it quickly became popular for its speed, affordability, and rich flavor. Its cousin, the Croque Madame, which includes a fried or poached egg on top, followed not long after.
Think of it as France’s answer to the grilled cheese sandwich—but elevated with creamy béchamel and high-quality ingredients. And once you try it, you’ll understand why it’s a staple of comfort food in French homes.

👩🍳 Step-by-Step Instructions
🥛 Step 1: Prepare the Béchamel Sauce
This creamy white sauce is the soul of the Croque Monsieur, giving it richness and moisture.
-
In a saucepan over medium heat, melt the butter.
-
Once foaming, whisk in the flour to make a roux. Cook for about 1–2 minutes, stirring constantly, until golden but not browned.
-
Gradually pour in the warm milk, whisking vigorously to avoid lumps.
-
Continue whisking until the sauce thickens (about 5–7 minutes).
-
Season with salt, pepper, and a pinch of nutmeg.
-
Turn off the heat and let the sauce cool slightly.
💡 Tip: For extra cheesiness, you can stir in ¼ cup of grated Gruyère at this stage to make it a Mornay sauce.
🍞 Step 2: Toast the Bread
You want your bread slices lightly toasted before assembling to prevent sogginess.
-
Toast the slices of bread in a toaster or under the broiler until golden but not too crisp.
-
Spread a thin layer of Dijon mustard on one side of each slice (optional, but highly recommended).
🍖 Step 3: Assemble the Sandwich
-
Place two slices of bread on a baking sheet, mustard-side up.
-
Layer with one slice of ham and about ¼ cup of grated cheese.
-
Top with the remaining bread slices to form two sandwiches.
-
Press lightly to compact.
🧈 Step 4: Pan-Fry (Optional but Flavorful)
For extra crunch and flavor, pan-fry the sandwiches before broiling.
-
Heat a skillet over medium heat with 1 tablespoon of butter.
-
Cook the sandwiches for 2–3 minutes per side until lightly browned.
🧀 Step 5: Top with Béchamel and Cheese
-
Spoon generous amounts of béchamel sauce over the tops of the sandwiches.
-
Sprinkle with the remaining grated Gruyère.
🔥 Step 6: Broil to Perfection
-
Preheat your broiler on high.
-
Place the baking sheet under the broiler and cook for 3–5 minutes, watching carefully.
-
When the top is bubbling, golden, and slightly crispy, remove from the oven.
⏲️ Step 7: Cool and Serve
Let the sandwiches cool for a minute or two before slicing diagonally. Serve hot, with a green salad or a glass of chilled white wine.
🥗 Serving Suggestions
-
Serve alongside a light salad with vinaigrette to balance the richness.
-
Pair with a French onion soup for a decadent lunch.
-
Add a fried egg on top to make it a Croque Madame.
-
Serve with cornichons and mustard on the side for a brasserie-style experience.
🍽️ Variations
-
Croque Madame: Top the sandwich with a poached or fried egg.
-
Vegetarian: Use sautéed mushrooms or roasted vegetables instead of ham.
-
Spicy: Add a dash of hot sauce or sliced jalapeños to the béchamel.
-
Gluten-Free: Use gluten-free bread and all-purpose gluten-free flour.
❄️ Storage & Reheating Tips
-
Refrigerator: Wrap leftovers and store in the fridge for up to 2 days.
-
Reheating: Place in the oven or toaster oven at 350°F for 10–12 minutes until heated through. Avoid microwaving—it makes the sandwich soggy.
