Ingredients

• 2 medium zucchini
• 2 medium yellow squash
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 1.5 cups whole milk
• 1 cup grated Parmesan cheese
• 1 cup shredded sharp cheddar cheese
• 0.5 teaspoon garlic powder
• 0.5 teaspoon onion powder
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 cup panko breadcrumbs
• 1 tablespoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

Wash and dry the zucchini and yellow squash. Using a sharp knife or mandoline slicer, thinly slice both into rounds about 1/8-inch thick. Set aside.

Step 3

In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1-2 minutes, stirring constantly, to form a roux.

Step 4

Gradually add the milk to the roux while whisking, ensuring a smooth sauce. Cook for 3-4 minutes, or until the mixture begins to thicken.

Step 5

Stir in the Parmesan cheese, cheddar cheese, garlic powder, onion powder, salt, and pepper. Mix until the cheeses are fully melted and the sauce is smooth. Remove from heat.

Step 6

Spread a thin layer of the cheese sauce on the bottom of the prepared baking dish.

Step 7

Arrange a single layer of zucchini and yellow squash slices over the sauce, slightly overlapping the slices. Pour a small amount of cheese sauce over the layer, spreading it evenly.

Step 8

Repeat layering the squash slices and cheese sauce until all the vegetables are used, finishing with a layer of cheese sauce on top.

Step 9

In a small bowl, mix the panko breadcrumbs with olive oil until evenly coated. Sprinkle the breadcrumb mixture over the top of the dish.

Step 10

Cover the dish with foil and bake for 25 minutes. Then, remove the foil and bake for an additional 15 minutes, or until the top is golden and bubbly.

Step 11

Let the dish rest for 5-10 minutes before serving. Enjoy!
