What Is a Croque Monsieur?

The Croque Monsieur is a warm French grilled sandwich traditionally made with ham and cheese. The name comes from the French words “croque,” meaning “crunch,” and “monsieur,” meaning “mister.” Together, the name reflects the sandwich’s crisp exterior and classic French character.

Unlike a regular grilled ham and cheese sandwich, the Croque Monsieur stands out because of its creamy béchamel topping and generous layer of melted cheese.

A traditional version usually includes:

• Sliced ham
• Gruyère or Emmental cheese
• White bread
• Béchamel sauce
• Butter

The sandwich is baked or broiled until the top becomes golden and the cheese turns beautifully melted and bubbly.

Ingredients

For the Sandwich

• 8 slices of thick white bread or brioche
• 8 slices of quality ham
• 1½ cups grated Gruyère cheese (or Emmental cheese)
• 2 tablespoons Dijon mustard (optional)
• 2 tablespoons butter, softened

For the Béchamel Sauce

• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 1 cup milk
• ¼ teaspoon salt
• ¼ teaspoon black pepper
• Pinch of nutmeg (optional)
• ½ cup grated Gruyère cheese

Choosing the Best Ingredients

The simplicity of a Croque Monsieur means ingredient quality matters.

Bread

Choose bread that is sturdy enough to hold the filling and sauce. Good options include:

• French sandwich bread
• Brioche
• Thick-cut white bread
• Country-style bread

Avoid very thin bread because it may become soggy.

Cheese

Gruyère is the traditional choice because it melts well and has a rich, slightly nutty flavor. Emmental, Comté, or Swiss cheese can also work well.

Ham

A good-quality cooked ham provides the best flavor. Thinly sliced deli ham works, but thicker slices create a more satisfying texture.

How to Make a Classic Croque Monsieur

Step 1: Prepare the Béchamel Sauce

Start by making the creamy sauce that gives this sandwich its signature flavor.

1. Melt butter in a small saucepan over medium heat.
2. Add flour and whisk continuously for about one minute.
3. Slowly pour in the milk while whisking to prevent lumps.
4. Continue cooking until the sauce thickens.
5. Add salt, pepper, and nutmeg if using.
6. Stir in grated cheese until smooth.

The finished sauce should be creamy and thick enough to spread on top of the sandwich.

Step 2: Assemble the Sandwiches

1. Spread a thin layer of butter on the outside of each bread slice.
2. Spread Dijon mustard on the inside if desired.
3. Add ham and grated cheese between two slices of bread.
4. Press gently to hold the sandwich together.

Step 3: Toast the Sandwiches

Heat a skillet over medium heat.

Cook the sandwiches until the bread becomes golden and crisp on both sides and the cheese begins to melt.

This step creates the classic crunchy texture.

Step 4: Add the Béchamel Topping

Place the toasted sandwiches on a baking tray.

Spread béchamel sauce over the top of each sandwich.

Add extra grated cheese on top.

Step 5: Bake Until Golden

Bake or broil until the cheese becomes melted, bubbly, and lightly golden.

Keep a close eye during this step because the topping can brown quickly.

Tips for the Perfect Croque Monsieur

Use Thick Bread

Thicker slices provide structure and prevent the sandwich from becoming too soft under the sauce.

Do Not Skip the Béchamel

The creamy sauce is what separates a Croque Monsieur from an ordinary ham and cheese sandwich.

Toast Before Baking

Lightly crisping the bread first helps maintain a satisfying texture.

Use Freshly Grated Cheese

Freshly grated cheese melts more smoothly than many pre-shredded varieties.

Balance the Ingredients

The best Croque Monsieur has a balance of:

• Crispy bread
• Creamy sauce
• Savory ham
• Rich melted cheese

Croque Monsieur Variations

Although the classic recipe remains popular, there are several delicious variations.

Croque Madame

The Croque Madame is a variation topped with a fried or poached egg.

The egg adds extra richness and makes the sandwich a popular breakfast or brunch option.

Vegetarian Croque

Replace ham with ingredients such as:

• Roasted mushrooms
• Spinach
• Grilled vegetables
• Tomato slices

Chicken Croque

Use sliced cooked chicken instead of ham for a different flavor.

Spicy Croque Monsieur

Add:

• A pinch of chili flakes
• Spicy mustard
• A little hot sauce

for extra heat.

What to Serve With Croque Monsieur

This French sandwich pairs beautifully with lighter sides.

Popular options include:

• Green salad with vinaigrette
• Tomato soup
• French fries
• Fresh fruit
• Pickles
• A cup of coffee or tea

A simple salad is especially common because it balances the richness of the sandwich.

Storage and Reheating

Croque Monsieur is best enjoyed fresh, but leftovers can be stored.

Refrigerating

Place leftovers in an airtight container and refrigerate for up to 2 days.

Reheating

For the best texture:

• Reheat in an oven or toaster oven.
• Avoid microwaving if possible because the bread may become soft.

Frequently Asked Questions

Can I make Croque Monsieur ahead of time?

You can prepare the sandwiches in advance and add the béchamel before baking. For the best texture, bake just before serving.

What cheese is best for Croque Monsieur?

Gruyère is traditional, but Emmental, Comté, and Swiss cheese are excellent alternatives.

Can I freeze Croque Monsieur?

Freezing is possible, but the texture may change slightly after reheating. Fresh preparation usually gives the best results.

Is Croque Monsieur the same as grilled cheese?

No. While both are warm cheese sandwiches, Croque Monsieur includes French-style ingredients such as ham and béchamel sauce.

Can I make it without béchamel?

Yes, but the result will be closer to a French-style grilled ham and cheese sandwich rather than a traditional Croque Monsieur.
