Croque Monsieur Recipe
Meet the Croque Monsieur Recipe: a gorgeous, golden-toasted French classic that takes your average ham and cheese sandwich to elegant new heights. This isn’t just lunch—it’s an experience of crisp bread, oozy Gruyère, savory ham, and a luxurious parmesan-laced béchamel that will transport you to a cozy Parisian café. Whether it’s brunch, dinner, or just a way to treat yourself on a weekday, it’s the kind of comforting meal you’ll crave long after the last melty bite.

Ingredients You’ll Need
The beauty of a Croque Monsieur Recipe lies in its simple, high-quality ingredients—each one lending something utterly delicious to the final bite. From the pillowy bread to that creamy, cheesy topping, every component deserves its place. Here’s what you’ll need:
- Bread: Choose classic white or a soft brioche for an irresistible, tender crunch when toasted.
- Dijon mustard: Adds a sharp, tangy kick that cuts through the richness and brings the flavors together.
- Ham: Parisian or Black Forest are best; luscious, thinly sliced ham is key for a delicate, savory bite.
- Gruyère cheese: This nutty, perfectly melty cheese is the heart of the sandwich—don’t skimp!
- Butter: Essential for that golden, buttery exterior and for the béchamel’s silky texture.
- All-purpose flour: Forms the thickening base for the luxuriously creamy béchamel sauce.
- Whole milk: Keeps the béchamel extra smooth and rich—full-fat is best for French comfort food.
- Salt: Just a pinch, to enhance every creamy, hammy note in this Croque Monsieur Recipe.
- Nutmeg: A little goes a long way, adding aromatic warmth to the sauce.
- Parmesan cheese: Blends with the sauce for a salty, complex layer beneath the Gruyère crust.
How to Make Croque Monsieur Recipe
Step 1: Make the Béchamel Sauce
Begin your Croque Monsieur Recipe journey by preparing the béchamel. In a small saucepan, melt butter over medium heat. Sprinkle in the flour and whisk, creating a paste. After a minute, slowly add milk while whisking constantly—the sauce will turn velvety and thick within 3 to 5 minutes. Take it off the heat, then stir in salt, nutmeg, and parmesan cheese, letting that aroma fill your kitchen. Set aside; this luscious sauce is your sandwich’s secret weapon.
Step 2: Prep and Toast Your Bread
Preheat your oven to 400°F. While it warms up, lightly toast all bread slices (either in a toaster or laid out on a baking sheet for a couple of minutes). This small step prevents sogginess and guarantees a crunchy golden bite that stands up to all that melty cheese and creamy sauce.
Step 3: Assemble the Sandwiches
Spread Dijon mustard onto four slices of the toasted bread. Top each slice with a generous helping of ham, then cover with half the Gruyère cheese. Place the remaining slices of toast on top to form four hearty sandwiches. Butter the outside of each sandwich for that signature, satisfying crunch this Croque Monsieur Recipe is loved for.
Step 4: Bake Until Golden
Lay your assembled sandwiches on a baking sheet. Bake in the oven for about 5 minutes per side, flipping once, until each is bronzed and slightly crisp. This gentle baking not only melts the Gruyère inside but ensures the bread’s exterior is perfectly toasted and buttery.
Step 5: Sauce and Broil
Take your sandwiches out of the oven and cloak each one with a generous spoonful of your reserved béchamel—don’t be shy. Sprinkle the rest of the Gruyère over the top. Slide the sandwiches back under the broiler for 2 to 3 minutes, watching closely, until the cheese bubbles and turns the most tempting golden brown. Your Croque Monsieur Recipe is now ready to be devoured while warm and gooey.
How to Serve Croque Monsieur Recipe

Garnishes
A Croque Monsieur Recipe is delightful all on its own, but a little garnish adds freshness and flair. Try a sprig of parsley, a light dusting of cracked black pepper, or a few cornichons on the side for a pleasing contrast to the rich flavors.
Side Dishes
Balance your indulgent sandwich with a simple salad tossed in a lemony vinaigrette, or serve with classic French fries for a café-inspired meal. A bowl of tomato soup also pairs beautifully, catching every melty string of Gruyère in its tangy depths.
Creative Ways to Present
For brunch, transform your Croque Monsieur into a Croque Madame by topping each with a sunny fried or poached egg. You might even slice the sandwiches into smaller triangles, arranging them on a platter for an enticing party nibble—French bistro chic in every bite!
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers (rare, but it happens!), wrap sandwiches tightly and refrigerate for up to two days. They’ll lose a touch of crispness but keep that decadent flavor ready for tomorrow’s lunch.
Freezing
To freeze, assemble the Croque Monsieur Recipe up to the baking step, then wrap sandwiches and place in an airtight container or freezer bag. Thaw overnight in the fridge before finishing in the oven and under the broiler for a fresh, melty finish.
Reheating
To bring back that just-baked magic, reheat sandwiches in a 350°F oven for about 10 to 12 minutes, or until warmed through and cheese is bubbling again. Avoid microwaving, which can make the bread chewy rather than crisp.
FAQs
What kind of bread works best for this Croque Monsieur Recipe?
Classic white sandwich bread or airy brioche both yield excellent results. Just be sure it’s sturdy enough to hold all the fillings and sauce without falling apart.
Can I substitute the Gruyère cheese?
While Gruyère brings a traditional nutty flavor, you can use Emmental, Swiss, or even a mild cheddar in a pinch. The melt and flavor profile may shift slightly, but it will still be delicious.
Is it possible to prepare the béchamel sauce in advance?
Absolutely! Make the sauce up to three days ahead and store it covered in the fridge. Just warm it gently before using to restore its creamy texture.
How do I make this recipe vegetarian?
Skip the ham and add layers of sautéed mushrooms or thinly sliced roasted vegetables for a satisfying vegetarian take on the classic Croque Monsieur Recipe.
What’s the difference between Croque Monsieur and Croque Madame?
A Croque Madame starts with the same base but gets topped off with a fried or poached egg, taking the decadence to new heights and making it perfect for brunch.
