• 3 medium zucchini , sliced
• 2 medium onions , sliced
• 3 tablespoons olive oil
• salt and ground black pepper to taste
• 1 , 16 ounce

• 0.5 cups grated Parmesan cheese

Instructions

1. 1 Preheat the oven to 400 degrees F (200 degrees C).
2. 2 Toss zucchini and onions in a large bowl with olive oil until evenly coated. Spread vegetables into a large baking dish.
3. 3 Roast in the preheated oven until golden, about 30 minutes. Remove from the oven and season with salt and pepper. Reduce the oven temperature to 350 degrees F (175 degrees C).
4. 4 When the vegetables are almost finished roasting, bring a large pot of lightly salted water to a boil. Add pasta and cook, stirring occasionally, until tender yet firm to the bite, about 11 minutes; drain.

6. 6 Heat marinara sauce in a saucepan over medium heat until hot. Spread hot sauce into the prepared baking dish. Top with cooked pasta, followed by roasted zucchini and onions. Sprinkle with Parmesan cheese.
7. 7 Bake in the preheated oven until sauce is bubbly, 35 to 40 minutes. Remove from the oven and let rest for a few minutes before serving.
