This Zucchini and Gruyère Gratin is a delectable vegetable side dish that combines the mild flavor of zucchini with the rich, nutty taste of Gruyère cheese. Baked to perfection with a crispy golden topping, this gratin is perfect for family dinners, holiday gatherings, or whenever you crave a creamy, cheesy vegetable dish.

Ingredients:
– 3 medium zucchinis, thinly sliced
– 1 onion, thinly sliced
– 2 cloves garlic, minced
– 1 cup grated Gruyère cheese
– 1/2 cup grated Parmesan cheese
– 1 cup heavy cream
– 2 tablespoons butter
– 1 tablespoon olive oil
– 1/2 cup breadcrumbs
– Salt and pepper to taste
– A pinch of nutmeg
– Fresh herbs for garnish (optional)

Instructions:

1. Preheat the oven: Set your oven to 375°F (190°C) to preheat.

2. Prepare the zucchini: Wash the zucchinis and slice them into thin rounds. Set aside.

3. Cook the onions and garlic: In a large skillet, heat the olive oil over medium heat. Add the sliced onions and cook until they start to soften, about 5 minutes. Add the minced garlic and cook for an additional 1-2 minutes until fragrant. Remove from heat.

4. Assemble the gratin: In a large mixing bowl, combine the sliced zucchinis, cooked onions, and garlic. Season with salt, pepper, and a pinch of nutmeg. In a separate bowl, mix the grated Gruyère and Parmesan cheeses.

5. Layer the ingredients: In a greased baking dish, start by spreading a single layer of the zucchini mixture. Sprinkle a portion of the cheese mixture over the zucchini. Repeat these layers until all the ingredients are used, finishing with a layer of cheese on top.

6. Add the cream: Pour the heavy cream evenly over the layers in the baking dish.

7. Prepare the breadcrumb topping: In a small bowl, mix the breadcrumbs with the melted butter until the crumbs are evenly coated. Sprinkle the breadcrumbs over the top layer of cheese.

8. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is golden brown and bubbly, and the zucchini is tender when pierced with a fork.

9. Let it rest: Remove the gratin from the oven and let it rest for 5-10 minutes before serving. This allows the flavors to meld and makes it easier to serve.

10. Garnish and serve: Garnish with fresh herbs if desired, and serve warm as a delicious side dish to your favorite meal.
