Ingredients

• 4 medium (about 1 pound total) yellow squash
• 3 medium roma tomatoes
• 1 small yellow onion
• 2 large garlic cloves
• 3 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 1 teaspoon dried Italian seasoning
• 2 tablespoons, chopped fresh parsley
• 1 cup shredded mozzarella cheese
• 0.5 cup grated Parmesan cheese
• 0.5 cup breadcrumbs
• 2 tablespoons, melted butter

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease an 8x8-inch baking dish with a thin layer of olive oil or cooking spray.

Step 2

Wash and slice the yellow squash into 1/4-inch thick rounds. Wash and slice the roma tomatoes into 1/4-inch thick rounds as well.

Step 3

Peel and finely dice the yellow onion. Mince the garlic cloves.

Step 4

In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until translucent.

Step 5

Add the minced garlic to the skillet and cook for an additional 1-2 minutes until fragrant. Remove from heat.

Step 6

In a large mixing bowl, combine the yellow squash, roma tomatoes, sautéed onion and garlic, salt, black pepper, dried Italian seasoning, and chopped fresh parsley. Toss gently to coat evenly.

Step 7

Layer the vegetable mixture evenly in the prepared baking dish.

Step 8

In a small bowl, mix the breadcrumbs, grated Parmesan cheese, and melted butter until the mixture resembles coarse crumbs.

Step 9

Sprinkle the shredded mozzarella cheese evenly over the vegetables, followed by the breadcrumb mixture.

Step 10

Cover the dish loosely with foil and bake in the preheated oven for 20 minutes. Then remove the foil and bake for an additional 10 minutes, or until the topping is golden brown and crispy.

Step 11

Remove the casserole from the oven and let it rest for 5 minutes before serving.

Step 12

Garnish with extra parsley if desired and serve warm as a side dish.
