Ingredient Notes

Bread: Thick slices of white sandwich bread, brioche, or sourdough work especially well. Choose bread sturdy enough to hold the filling without becoming soggy.

Ham: Thinly sliced cooked ham provides the classic savory filling. Black Forest ham can also add a slightly smokier flavor.

Gruyère: This is one of the best cheeses for a Croque Monsieur because it melts beautifully and has a rich, slightly nutty flavor.

Mozzarella: Adding mozzarella creates an extra stretchy, gooey cheese center.

Dijon Mustard: A thin layer adds acidity and a gentle sharpness that balances the richness of the cheese.

Butter: Softened butter helps create that irresistible crisp, deeply golden exterior.

Prep Time & Servings

Prep Time: 10 minutes
Cook Time: 12 minutes
Total Time: 22 minutes
Servings: 4 sandwiches

Ingredients

8 thick slices white bread, brioche, or sourdough
8 slices cooked ham
8 slices Gruyère or Swiss cheese
1 cup shredded mozzarella cheese
2 tablespoons Dijon mustard
3 tablespoons unsalted butter, softened
¼ teaspoon freshly ground black pepper
Fresh parsley, finely chopped, for garnish

Instructions

Prepare the bread. Place the bread slices on a clean work surface. Spread softened butter over one side of each slice.
Add the Dijon mustard. Turn the bread over and spread a thin layer of Dijon mustard over the inside of four slices.
Add the ham. Place two slices of ham over each mustard-covered slice of bread, folding them slightly so they fit neatly.
Add the cheese. Top the ham with Gruyère or Swiss cheese, followed by a generous sprinkle of shredded mozzarella.
Close the sandwiches. Place the remaining bread slices on top with the buttered sides facing outward. Press gently.
Heat the skillet. Place a large skillet over medium-low to medium heat and allow it to warm for about 1–2 minutes.
Cook the first side. Add the sandwiches without overcrowding the skillet. Cook for approximately 3–4 minutes until the bottoms are deeply golden and crisp.
Flip carefully. Turn each sandwich over and cook for another 3–4 minutes.
Melt the cheese completely. Reduce the heat slightly and cover the skillet for the final 1–2 minutes. The trapped heat will help the cheese melt without burning the bread.
Serve immediately. Transfer the sandwiches to a cutting board and allow them to rest for about one minute. Slice in half, garnish with fresh parsley, and serve while the cheese is still warm and gooey.

Tips for the Best Croque Monsieur

Cook the sandwiches over medium-low rather than high heat. This gives the cheese enough time to melt before the bread becomes too dark.

Use freshly grated Gruyère whenever possible. Pre-shredded cheese often doesn’t melt quite as smoothly.

Don’t add too much Dijon mustard. A thin layer is enough to brighten the sandwich without overpowering the cheese.

For an especially crispy exterior, spread the softened butter all the way to the edges of the bread.

Let the sandwich rest for about one minute before slicing. The cheese will remain beautifully melted but won’t immediately spill out.

Variations

Traditional Béchamel Croque Monsieur: Add a layer of creamy béchamel sauce and Gruyère over the top, then broil until bubbling and golden.

Croque Madame: Top the finished sandwich with a fried egg.

Extra Cheesy Croque Monsieur: Increase the Gruyère and add additional shredded mozzarella to the center.

Turkey Croque Monsieur: Replace the ham with thinly sliced roasted turkey.

Sourdough Version: Use thick sourdough slices for extra crunch and a slightly tangy flavor.

What to Serve with Croque Monsieur

A rich Croque Monsieur pairs especially well with a simple green salad dressed with Dijon vinaigrette.

You can also serve it with tomato soup, roasted vegetables, crispy potatoes, French fries, or fresh fruit for a complete meal.

For brunch, pair it with eggs and a lightly dressed salad.

Storage and Reheating

Croque Monsieur is best served immediately while the bread is crisp and the cheese is melted.

If you have leftovers, allow them to cool before transferring them to an airtight container. Refrigerate for up to 2 days.

For the best texture, reheat the sandwich in a skillet over low heat or in a 350°F (175°C) oven until warmed through.

Avoid reheating it for too long in the microwave because the bread can become soft.
