    Prepare the zucchinis: Place slices in a colander, sprinkle with salt and let drain 10-15 min. Rinse and pat dry.

  3. 3

    Pour cream into the pan, add thyme, salt and pepper. Bring to a simmer for 2 min then remove from heat.

  4. 4

    In an oiled baking dish, alternate layers of zucchini, cream and parmesan (reserving some). Finish with cream.

    Cover with foil and bake for 25 min. Remove foil, sprinkle reserved parmesan and thyme. Bake for 10 more min.

  6. 6

    Let rest 5-10 min before serving.

Tips & Tricks
  • Salting: Key to avoid a watery gratin, especially with large zucchinis.
  • Even slicing: A mandoline ensures even slices for uniform cooking.
  • Cheese: Grate parmesan at the last moment for a better gratin.
  • Doneness test: Zucchinis are cooked when a knife pierces easily.
  • Serving: Pair with white meat, fish or a green salad.
  • Variations: Try with béchamel, sun-dried tomatoes or sausage meat.
