Let's cook

  1. Warm the croissants first

    Split and warm the croissants in a 350°F oven for 4 minutes. A cold croissant is dense and slightly waxy; warm, it turns flaky again.

    💡

    Four minutes in the oven transforms a shop-bought croissant.

  2. Scramble softly

    Melt the butter over low heat and stir the eggs constantly, pulling the pan off the heat now and then. Stop while still glossy.

  3. Mustard the base

    Spread a thin layer of Dijon on the bottom half. It cuts the richness of butter, cheese, and egg.

  4. Layer and melt

    Stack ham, eggs, and cheese, then return the open sandwich to the oven for 3 minutes until the cheese melts.

  5. Close and press

    Add the lid, press gently, and serve at once with chives and cracked pepper.

📝 Tips, swaps, and make-ahead notes

Day-old croissants are actually preferable here, since they hold up better to the filling and revive well in the oven. Griddling the closed sandwich for a minute a side gives a croque-monsieur effect.

  • Vegetarian: Roasted mushrooms or avocado in place of the ham.
  • Sweet: Skip the savoury filling; fill with jam and mascarpone.
  • Make-ahead: Assemble cold, wrap, and bake at 350°F for 12 minutes.
