Ingredients

For the Gratin

2 tbsp unsalted butter Adds richness and depth to the sauce.
2 tbsp all-purpose flour Acts as a thickener for the creamy sauce.
1 tsp salt Enhances the overall flavors in the gratin.
0.5 tsp freshly ground black pepper Adds a touch of warmth and depth.
1 cup whipping cream Provides the luxurious creaminess that characterizes the dish.
0.5 cup grated Parmesan cheese Introduces a salty, nutty flavor to the layers.
1 cup shredded mozzarella cheese Gives a gooey, melted texture on top of the gratin.
0.5 cup Gruyere cheese Adds a touch of sweetness and complexity to the flavor profile.
4 small zucchini Acts as the main vegetable, providing freshness and vibrancy.
2 tbsp snipped fresh chives Offers a pop of color and mild onion flavor as a garnish.

Method

Preparation

Preheat the oven to 400°F to prepare for baking.
Lightly spray a 2-quart casserole dish with cooking spray and set aside.
In a small saucepan, melt the unsalted butter over medium heat, then whisk in flour, salt, and black pepper.
Gradually add the whipping cream, stirring for about 2 minutes until it thickens. Incorporate half of the Parmesan cheese.

Cooking

Arrange half of the sliced zucchini in the prepared dish, overlapping them slightly.
Spread half of the sauce over the zucchini, followed by half of the mozzarella and Gruyere cheeses.
Add another layer of zucchini and sauce, then top with the remaining mozzarella and Parmesan cheese.

Baking

Bake for 25 minutes or until the zucchini is fork tender and the top begins to brown.
Sprinkle with fresh chives before serving to enhance flavor and presentation.

Notes

Use fresh zucchini for optimal flavor and texture. Experiment with different cheese combinations to customize the flavor. Store leftovers in an airtight container for up to three days. Can be frozen for up to 2 months before baking.
