Ingredients You’ll Need
This recipe calls for a handful of straightforward ingredients that come together beautifully to create the perfect balance of textures and flavors. Each component plays a vital role: the crusty bread provides crunch, the ham brings a salty savoriness, the Gruyère offers richness and that signature melt, and the buttery and cheesy topping seals the deal with creamy goodness.
- 4 slices crusty bread: Choose a sturdy bread like pain de mie or a rustic white loaf to withstand grilling without getting soggy.
- 4 slices ham (jambon de Paris preferred): Classic French cooked ham is mild and tender, perfect for layering.
- 4 slices Gruyère cheese: This cheese melts beautifully, adding nutty flavor and a smooth texture.
- 2 tbsp butter (softened): Butter lends richness and helps crisp the bread to a sublime golden brown.
- 1 tbsp Dijon mustard (optional): Adds a subtle tang and depth, elevating the overall flavor without overpowering.
- 1/4 cup milk: Used to create the creamy cheese topping that finishes the sandwich.
- 1/2 cup grated Gruyère (optional topping): Enhances the creamy béchamel-style topping with extra cheesiness and a browned crust.
- Salt & pepper to taste: Essential for seasoning the creamy mixture and balancing flavors.
How to Make Croque Monsieur – Classic French Ham & Cheese Sandwich
Step 1: Prepare the Bread and Spread
Start by spreading the softened butter evenly on one side of each slice of bread. If you’re a fan of that little extra zing, spread a thin layer of Dijon mustard on the unbuttered side of the bread before assembling. This little step imbues the sandwich with a subtle piquancy that beautifully contrasts with the richness of the cheese and ham.
Step 2: Layer the Ham and Cheese
On the mustard-spread slices, layer the ham first, giving that salty, tender meat center stage. Next, pile on the slices of Gruyère cheese for that irresistible creamy melt. Top with the remaining bread slices, making sure the buttered sides face outwards—this trick ensures your sandwich crisps beautifully when cooked.
Step 3: Grill to Golden Perfection
Place your assembled sandwiches in a skillet over medium heat or an air fryer preheated to 350°F (175°C). Cook for about 7 to 10 minutes, flipping once halfway through, until the bread is crisp and delectably golden, and the cheese inside has melted into gooey bliss. This is when the magic really happens—crispy, buttery exterior meets melty, savory interior.
Step 4: Make the Creamy Cheese Topping
While your sandwiches are close to done, whisk together the milk, grated Gruyère, and a pinch of salt and pepper. Spoon this mixture over each sandwich and continue cooking for a couple of minutes. To finish, pop the sandwiches under the broiler for 2 minutes, or until the topping bubbles and turns a gorgeous golden brown. The result? A luscious, creamy crust that’s every bit as indulgent as it sounds.
How to Serve Croque Monsieur – Classic French Ham & Cheese Sandwich

Garnishes
To enhance the dish’s appearance and flavor, sprinkle chopped fresh parsley or a few cracked black peppercorns on top right before serving. A light dusting of grated nutmeg on the creamy topping adds a subtle warm spice that complements the cheese and ham beautifully.
Side Dishes
The Croque Monsieur – Classic French Ham & Cheese Sandwich pairs wonderfully with a crisp green salad tossed in a tangy vinaigrette to balance the richness, or some buttery steamed asparagus for a touch of elegance. For a heartier side, consider a bowl of French onion soup or a small portion of pommes frites to keep it authentically French.
Creative Ways to Present
Want to impress guests? Cut the sandwich diagonally to reveal its melty layers, then stack the halves slightly overlapping on a warm plate. Serve with a small ramekin of Dijon mustard or whole grain mustard on the side for dipping. Alternatively, try mini Croque Monsieur bites for a playful appetizer at your next brunch or casual gathering.
Make Ahead and Storage
Storing Leftovers
Leftover Croque Monsieur is best stored in an airtight container in the refrigerator for up to 2 days. Keep the sandwich intact to preserve the melty cheese interior and the creamy topping, then reheat gently to maintain its texture and flavor.
Freezing
You can freeze uncooked assembled sandwiches by wrapping them tightly in plastic wrap and then foil. Freeze for up to one month. When ready to eat, thaw overnight in the fridge, then cook fresh as directed for optimal crispness and cheesiness.
Reheating
Reheat your Croque Monsieur in a preheated oven or air fryer at 325°F (160°C) for about 10 minutes. Avoid the microwave to prevent sogginess. If needed, broil briefly at the end to revive that irresistible golden cheese topping.
