Croque Monsieur

The classic French cafe sandwich — ham and cheese between toasted bread, topped with béchamel and a blanket of Gruyère, baked until golden. Crisp outside, molten cheese within. Add a runny fried egg on top and it becomes a "croque madame".

Tips & Variations

Variations

  • Croque madame: Top with a runny fried egg.
  • Mushroom version: Add sautéed mushrooms.
  • Chicken croque: Use chicken instead of ham.
  • Mini croques: Make small ones on baguette as a snack.

Tips

  • Whisk warm milk in gradually for a smooth, lump-free béchamel.
  • Gruyère gives the signature nutty flavor, but mozzarella or cheddar work.
  • Pile cheese on top and brown it under the broiler for the best crust.
  • One runny egg turns it into a croque madame — break the yolk and dig in.
