Equipment

Notes

    • Use slightly stale croissants for the best texture. They soak up the custard without becoming soggy after it’s baked.
    • Gruyere can be expensive, so feel free to use sharp white cheddar, Swiss, Gouda, Fontina, or Monterey Jack instead. Smoked cheese is a fun addition, too!
    • Let the bake rest before serving to help redistribute any moisture so it’s not dry.
