Yield: 6 servings


  • 4 medium zucchini, thinly sliced
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 2 cups heavy cream
  • 1 cup grated Gruyere cheese
  • 1 cup grated Parmesan cheese
  • 1/2 cup breadcrumbs
  • 2 tablespoons butter, melted
  • Salt and pepper, to taste

  1. Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  2. Spread the zucchini slices evenly in the prepared baking dish and season with salt and pepper.
  3. In a medium saucepan, sauté the onion and garlic in a little oil until soft and fragrant.
  4. Add the heavy cream to the saucepan and bring to a simmer. Stir in the Gruyere and half of the Parmesan cheese until melted and smooth. Season with salt and pepper to taste.
  5. Pour the cheese sauce over the zucchini in the baking dish, making sure all the zucchini slices are covered.
  6. In a small bowl, mix the breadcrumbs, melted butter, and remaining Parmesan cheese. Sprinkle the mixture evenly over the top of the zucchini and cheese sauce.
  7. Bake the zucchini gratin for 40 minutes or until the top is golden brown and the sauce is bubbly.
  8. Remove from the oven and let cool for a few minutes before serving. Garnish with fresh parsley if desired.

Tips and Tricks:

  • For a crispier topping, you can broil the gratin for an additional 2-3 minutes after baking.
  • If your zucchini is particularly watery, you can salt the slices and let them sit for 15-20 minutes before patting dry with paper towels.

Substitution Options:

  • For a lighter option, you can substitute the heavy cream with half-and-half or whole milk.
  • If you don’t have Gruyere cheese, you can use Swiss, Emmental, or Fontina cheese.

Wine or Beverage Pairings:

A crisp white wine, such as Sauvignon Blanc or Pinot Grigio, would pair beautifully with this zucchini gratin. Alternatively, a light and refreshing lager beer would also complement the dish nicely.
