Ingredients

Method

  1. Heat the oven grill or broiler to high and line a small baking tray with parchment.
  2. Make the béchamel by melting 15g butter in a small saucepan over medium heat, then whisk in the flour and cook for 1 minute without browning.
  3. Whisk in the milk gradually until smooth, then simmer for 2 to 3 minutes until thick enough to coat a spoon.
  4. Season the béchamel with salt, pepper, and a pinch of nutmeg, then remove it from the heat.
  5. Lightly butter one side of each bread slice with the remaining butter.
  6. Place 2 slices buttered-side down in a skillet over medium heat and spread the top of each with Dijon mustard.
  7. Add a thin spoonful of béchamel, 2 slices of ham, and about half of the grated cheese between the two sandwiches.
  8. Close with the remaining bread slices, buttered-side up, and cook for 2 to 3 minutes per side until the bread is crisp and golden.
  9. Transfer the sandwiches to the prepared tray and spread the remaining béchamel over the tops.
  10. Sprinkle with the remaining grated cheese and grill for 3 to 5 minutes until deeply golden, bubbling, and lightly browned in spots.
  11. Let the croque-monsieurs rest for 1 minute before serving hot.

Common questions

Can I substitute the jambon de Paris and Gruyère in a croque-monsieur?

Yes. Use any mild deli ham and a good melting cheese such as Emmental, Comté, or even Swiss. Avoid strongly aged or oily cheeses, which can make the sandwich dry or overly salty.

How long does it take to make croque-monsieur from start to finish?

Plan for about 20 to 25 minutes total. The béchamel takes 5 to 7 minutes, assembling takes a few minutes, and pan-frying plus broiling usually takes another 8 to 12 minutes.

What are the most common mistakes when making croque-monsieur?

The biggest mistakes are over-thick béchamel, too much mustard, and using heat that is too high. Keep the sauce spoonable, use a light layer of mustard, and cook gently so the bread browns before the filling leaks out.

Can I store leftovers or make croque-monsieur ahead of time?

It is best eaten immediately, but leftovers can be refrigerated for up to 1 day. Reheat in a skillet or oven to re-crisp the bread. Assemble ahead without cooking, then cook and broil just before serving.

What should I serve with croque-monsieur?

Serve it hot with a simple green salad dressed with sharp vinaigrette, cornichons, or a light soup. The acidity cuts the richness and keeps the meal balanced without competing with the béchamel and cheese.
