Perfectly cooked ziti is tossed in a smooth, creamy vegetable-based sauce made with onion, garlic, carrots, broccoli, and cauliflower, then baked under a blanket of bubbling cheese until golden.
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Place onion, garlic, carrots, broccoli, and cauliflower on the sheet. Drizzle with olive oil, season lightly with salt and pepper, and roast for 20–25 minutes, until tender and slightly golden.
While the vegetables roast, prepare the marinara: heat olive oil in a saucepan, add tomato passata, basil, oregano (if using), salt, and pepper. Simmer gently for 10–15 minutes. Remove from heat.
Transfer the roasted vegetables to a blender or food processor. Add the marinara sauce, cream and blend until completely smooth. Add vegetable broth if the sauce is too thick. Taste and adjust seasoning.
Meanwhile, cook the pasta in salted boiling water for half the cooking time mentioned in the package. Drain and set aside. If you're not ready to bake immediately, wash the pasta under cold water to stop it from cooking.
Spread a few ladles of sauce on the bottom of a 9x13 inch (23x33 cm) baking dish.
Add half of the pasta in the dish. Spoon the ricotta cheese evenly over the pasta layer. Pour over half of the veggie sauce and spread evenly.
Add the remaining pasta and pour the rest of the veggie sauce on top, spreading it evenly.
Sprinkle with mozzarella and Parmesan cheese.
Bake uncovered for 20–25 minutes, until bubbly and golden on top.
Let rest for 5 minutes before serving.
