Ingredients

• ¾ lb. zucchini
• ¾ lb. yellow summer squash
• 2 tablespoons olive oil divided
• ½ teaspoon minced garlic
• ½ cup finely-diced onion
• 1 cup canned unsalted crushed plum tomatoes in juice
• 1 tablespoon fresh basil
• 1 tablespoon fresh parsley
• ½ teaspoon salt
• ¼ teaspoon pepper
• 3 tablespoons grated Parmesan cheese

Instructions

1. Preheat oven to 400°F (200°C). Spray a medium-sized baking dish with cooking spray and set aside (I used a deep 5-inch by 9-inch dish, but a 7x11-inch dish or anything similar in size will work well).

2. Slice zucchini and squash into thin rounds (I like to use a mandolin to make it fast and uniform, but it’s not necessary).
3. In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add garlic and cook (stirring constantly) for about 1 minute. Add zucchini and squash to the skillet. Stir and cook until vegetables are tender (about 5-6 minutes). Remove from heat.
4. In a small saucepan, add remaining 1 tablespoon of oil and diced onion. Cook onion over medium heat until translucent (about 2 minutes), and then add the tomatoes (with their juice) and the basil. Simmer tomatoes about 5 minutes. Stir in parsley, salt, and pepper to taste.
5. Spread half of the zucchini/squash mixture into the bottom of the prepared baking dish. Cover with half of the tomato sauce from the saucepan, and sprinkle with 1 tablespoon of grated Parmesan.
6. Add another layer with the remaining zucchini, top with the remaining sauce, and finish with the last 2 tablespoons of Parmesan.
7. Bake for 15 minutes, or until cheese is melted and the top becomes golden brown.
8. Allow dish to sit for about 10 minutes before serving.
