Gratin de Christophine

About This Recipe

Gratin de Christophine is the most beloved vegetable dish of Martinique. Christophine (chayote squash) is scooped, mashed, and mixed with a béchamel-style sauce, spring onions, garlic, gruyère, and nutmeg, then baked in its own shell until golden and bubbling. It appears on every Martinican Sunday table and festive meal as both a side dish and sometimes a light main course.
