The croque monsieur is not a grilled cheese sandwich. It is something categorically better: two slices of brioche or pain de mie buttered and toasted, filled with French ham and aged Gruyère, and then — and this is the part that matters — coated on top with a Dijon-spiked béchamel and returned to the broiler until the sauce turns golden, bubbling, and slightly charred at the edges.
It sounds luxurious because it is, but the process is methodical rather than difficult. Make a quick béchamel, assemble the sandwiches, and finish under the broiler. The resulting sandwich is crispy-bottomed, molten in the middle, and covered in a savory, lightly crisped sauce that is genuinely unlike anything else in the sandwich world. Add a fried egg on top and you have a croque madame.

Kitchen notes for Croque Monsieur
Before you start
Set up the first moves
Start by having (about 5 oz) gruyère, grated, divided, slices thick brioche or white bread, and unsalted butter, softened (for spreading) ready, then make béchamel: melt 2 tbsp butter in a small saucepan over medium heat.
Timing read
35 minutes, mostly cooking
Plan for 15 minutes prep and 20 minutes cooking. Midway check: Place sandwiches on a foil-lined baking sheet.
Flavor logic
Built around (about 5 oz) gruyère, grated, divided
(about 5 oz) gruyère, grated, divided, slices thick brioche or white bread, unsalted butter, softened (for spreading), and slices french ham (jambon blanc) or good deli ham carry the main flavor and texture, so measure them before you adjust seasoning or heat.
Serving plan
4 servings, 4 sandwiches
For French and Breakfast, the finish should match this final cue: Let rest 2 minutes before cutting.

Ingredient notes
Ingredients worth checking
Shopping focus
Prioritize (about 5 oz) gruyère
(about 5 oz) gruyère, slices thick brioche or white bread, unsalted butter, and slices french ham (jambon blanc) or good deli ham carry most of the flavor. Spend attention there first.
Prep notes
Prep in recipe order
Set up the ingredients in list order and keep time-sensitive items nearby.
Adjustment logic
Gruyère can flex
If needed, use Comté or Emmental in place of Gruyère. Very similar flavor profile. All three are excellent.
Optional items
Keep the core intact
Keep the main items intact; use garnish, heat, or acidity for small adjustments.

Why the olive oil matters
A clean everyday olive oil is useful for browning, roasting, and finishing without adding harsh flavor. It is one of the safest pantry upgrades for savory cooking.
This is a reusable staple, not a single-use ingredient.
- Useful for browning and roasting
- Works across vegetables, pasta, beans, fish, and chicken
A good everyday olive oil earns its space because it shows up in so many recipes.

Instructions
- 1
Make béchamel: melt 2 tbsp butter in a small saucepan over medium heat. Add flour and whisk for 1-2 minutes. Gradually add milk, whisking constantly until smooth. Cook until thickened, about 3-4 minutes. Season with nutmeg, salt, and white pepper. Remove from heat.
- 2
Preheat broiler to high. Butter one side of all bread slices. Toast buttered-side down in a skillet or dry pan until golden, 2-3 minutes.
- 3
Spread Dijon on the untoasted side of 4 slices. Layer 2 slices ham and a quarter of the Gruyère on each. Close with remaining slices, toasted-side out.
- 4
Place sandwiches on a foil-lined baking sheet. Spread 2-3 tbsp béchamel on top of each sandwich. Scatter remaining Gruyère over the sauce.
- 5
Broil 3-5 minutes until sauce is golden and bubbling and cheese is deeply browned. Watch carefully — it goes from golden to burned quickly.
- 6
Let rest 2 minutes before cutting. Serve immediately with a green salad or cornichons.

Substitutions
GruyèreComté or Emmental
Very similar flavor profile. All three are excellent.
French hamProsciutto cotto or turkey

Tips & Storage
Pro Tips
Make the béchamel first so it has time to cool slightly — this prevents it from making the bread soggy.
Gruyère is the correct cheese here; substitutes will work but the nutty, complex flavor of Gruyère is what makes this dish.
For a croque madame, add a fried egg on top just before serving.
This is a restaurant dish meant to be served immediately — have everything prepped before the broil step.
Storage
Best eaten immediately. Assembled, unbaked sandwiches can be refrigerated for several hours before broiling.
Reheating
Reheat in a 375°F oven for 8-10 minutes. Do not microwave.

Frequently Asked Questions
- What is the difference between croque monsieur and croque madame?
- A croque madame has a fried egg on top. The egg is said to resemble a lady's hat.
- Can I use Emmental or Swiss instead of Gruyère?
- Yes, they are closely related. Comté is another excellent option. Avoid pre-shredded cheese which contains anti-caking agents that prevent smooth melting.
- Can I make this without béchamel?
- You can, but then it's just a grilled ham and cheese, not a croque monsieur. The béchamel is the defining element.
