Ingredients

• 2 medium Zucchini
• 2 medium Summer squash
• 2 tablespoons Olive oil
• 2 cloves Garlic
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 tablespoon Fresh thyme leaves
• 0.5 cup Heavy cream
• 1 cup Grated Parmesan cheese
• 0.5 cup Breadcrumbs
• 1 tablespoon Butter

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Thinly slice the zucchini and summer squash into 1/8-inch rounds. Use a mandoline for uniform slices if available.

Step 3

Heat 1 tablespoon of olive oil in a small skillet over medium heat. Finely mince the garlic and sauté it for 1-2 minutes until fragrant, being careful not to let it burn.

Step 4

In a large mixing bowl, combine the sliced zucchini and summer squash, sautéed garlic, salt, black pepper, and fresh thyme leaves. Mix gently to coat the vegetables evenly.

Step 5

Lightly grease a 9-inch baking dish with the remaining 1 tablespoon of olive oil. Arrange the zucchini and summer squash slices in the dish, slightly overlapping them in rows or a spiral pattern for a visually appealing presentation.

Step 6

Drizzle the heavy cream evenly over the squash layers.

Step 7

Sprinkle 3/4 cup of the grated Parmesan cheese over the top of the dish.

Step 8

In another small bowl, mix the breadcrumbs with the remaining 1/4 cup of Parmesan cheese. Melt the butter and stir it into the breadcrumb mixture until evenly combined.

Step 9

Sprinkle the breadcrumb mixture over the top of the squash and cheese layers.

Step 10

Cover the baking dish tightly with foil and bake in the preheated oven for 20 minutes.

Step 11

Remove the foil and continue baking for an additional 10 minutes, or until the top is golden brown and bubbling.

Step 12

Let the gratin cool for 5 minutes before serving. Garnish with additional thyme leaves if desired.
