Julia Child’s Zucchini Gratin Recipe

4.8 from 61 reviews

Julia Child’s Zucchini Gratin is a classic French-inspired baked dish featuring tender zucchini and onions cooked in butter, then topped with a savory mixture of Parmesan cheese and crispy breadcrumbs for a golden, flavorful crust.

Ingredients

Scale

Vegetables

  • 4 medium zucchinis, thinly sliced
  • 1 large onion, finely chopped

Dairy & Fats

  • 3 tablespoons unsalted butter
  • 1 cup grated Parmesan cheese

Other

  • 1/2 cup breadcrumbs

Instructions

  1. Prepare the vegetables: Begin by washing and thinly slicing the zucchinis. Finely chop the onion to ensure even cooking and flavor distribution.
  2. Cook the zucchini and onion: In a large skillet, melt the butter over medium heat. Add the sliced zucchinis and chopped onion, cooking gently until they are softened but not browned, about 8-10 minutes. Stir occasionally to prevent sticking.
  3. Assemble the gratin: Transfer the cooked zucchini and onions evenly into a baking dish. Sprinkle a generous layer of grated Parmesan cheese over the top, and then evenly distribute the breadcrumbs to form a crisp topping.
  4. Bake the gratin: Preheat the oven to 375°F (190°C). Place the baking dish in the oven and bake for 20-25 minutes, or until the topping is golden brown and crispy and the gratin is bubbling gently around the edges.
  5. Serve: Remove the gratin from the oven and allow it to cool slightly before serving to let the flavors meld and the gratin set for easier portioning.

Notes

  • For a richer flavor, you can sprinkle some freshly ground black pepper or nutmeg over the vegetables before baking.
  • If you prefer a crunchier topping, you can toast the breadcrumbs lightly in butter before sprinkling.
  • Use freshly grated Parmesan for the best flavor and melting quality.
  • This dish pairs beautifully as a side to roasted meats or as a vegetarian main with a fresh salad.
