Cheesy Scalloped Zucchini

INGREDIENTS :

• Unsalted butter, softened, as needed
• 1 lb zucchini, thinly sliced
• 2/3 cup heavy cream
• 1 teaspoon dried thyme
• 1/2 teaspoon garlic powder
• 1/2 cup Parmigiano-Reggiano, freshly grated
• 1 1/2 tablespoons all-purpose flour
• 1/2 cup Gruyere cheese, freshly grated
• 1/3 cup panko breadcrumbs
• Kosher salt and freshly ground black pepper, to taste

PREPARATION :

1. Position a rack in your oven 6 inches from the broiler and heat broiler on high.
2. Grease a shallow 9×13-inch baking dish or rimmed sheet pan with softened butter.
3. Season zucchini with salt and pepper and arrange on baking pan. Broil just until squash is beginning to soften, about 4 minutes.
4. While squash bakes, whisk together cream, thyme, garlic powder, parmesan cheese, and flour in a small bowl. Pour mixture evenly over squash, then top with Gruyere cheese and panko breadcrumbs.
5. Return to oven and broil until golden brown and bubbly, 4-5 minutes. Enjoy!
