Zucchini and Yellow Squash Au Gratin

Preparation and Layering

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter to prevent sticking and enhance flavor.
2. Layer the Vegetables: Arrange half of the sliced zucchinis and yellow squashes in an even layer in the baking dish. Sprinkle half of the sliced onions and minced garlic over the vegetables. Season with salt, pepper, and a bit of thyme. Repeat the layers with the remaining vegetables and season again.

Creating the Creamy Base

3. Heat the Cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Pour the hot cream evenly over the layered vegetables.

Adding the Cheesy Crust

4. Add Cheese: Sprinkle half of the Parmesan and Gruyere cheeses over the vegetables. In a small bowl, mix together the breadcrumbs and the remaining cheeses. Spread the breadcrumb mixture evenly over the top. Dot with butter, cut into small pieces.

Baking to Perfection

5. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and continue baking for another 15-20 minutes, or until the top is golden brown and the vegetables are tender.
6. Rest and Serve: Allow the gratin to rest for a few minutes before serving. This helps set the layers and makes it easier to serve.
