Ingredients

To make the best zucchini gratin recipe, you’ll need:

  • 200 ml heavy cream (or cooking cream)

  • 100 ml milk

  • 150 g shredded mozzarella cheese

  • 50 g grated Parmesan cheese

Step-by-Step Preparation

Step 1: Prepare the Zucchini

Wash the zucchini and slice them into even rounds (about 0.5 cm thick).

For best results, lightly salt them and let them rest for 10 minutes to release excess moisture. Then pat dry with paper towels. This step prevents a watery gratin.

Step 2: Prepare the Creamy Mixture

In a large bowl, whisk together:

  • Eggs

  • Cream

  • Milk

  • Garlic

  • Salt

  • Pepper

  • Nutmeg

Mix until smooth and well combined.

Step 3: Assemble the Gratin

  1. Preheat oven to 180°C (350°F).

  2. Lightly grease a baking dish with olive oil.

  3. Arrange zucchini slices in overlapping layers.

  4. Pour the creamy mixture evenly over the zucchini.

  5. Sprinkle mozzarella and Parmesan generously on top.

Step 4: Bake to Perfection

Bake for 35–40 minutes, or until:

  • The top is golden brown

  • The center is set

  • The edges are bubbling

For an extra golden crust, broil for 2–3 minutes at the end.

Let rest 10 minutes before serving.
