Ingredients

• 2 medium zucchini
• 2 medium yellow squash
• 2 tablespoons olive oil
• 2 cloves garlic
• 1 small onion
• 1 teaspoon Italian seasoning
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 1 cup shredded mozzarella cheese
• 0.5 cup grated Parmesan cheese
• 0.5 cup panko breadcrumbs
• 2 tablespoons butter
• 1 tablespoon fresh parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Wash and thinly slice the zucchini and yellow squash into 1/4-inch rounds.

Step 3

Heat the olive oil in a large skillet over medium heat. Add the minced garlic and diced onion, and sauté for 2-3 minutes until fragrant and softened.

Step 4

Add the sliced zucchini and yellow squash to the skillet. Season with Italian seasoning, salt, and black pepper. Cook for about 5 minutes, stirring occasionally, until the vegetables are slightly tender but not fully cooked.

Step 5

Lightly grease a 9x9-inch baking dish (or equivalent) with butter or non-stick spray. Layer the cooked zucchini and yellow squash mixture evenly in the dish.

Step 6

In a small mixing bowl, combine the shredded mozzarella cheese, grated Parmesan cheese, and panko breadcrumbs.

Step 7

Melt the butter and drizzle it over the breadcrumb and cheese mixture. Stir until the mixture is evenly moistened.

Step 8

Sprinkle the breadcrumb and cheese mixture evenly over the zucchini and squash in the baking dish.

Step 9

Bake the casserole in the preheated oven for 20-25 minutes, or until the top is golden brown and the casserole is bubbly.

Step 10

Remove from the oven and let it cool for a few minutes before serving. Garnish with fresh parsley if desired.
