Preheat your oven to 425°F (220°C). Line two large baking sheets with parchment paper.
In a large bowl, toss all the cut vegetables with olive oil, minced garlic, Italian seasoning, salt, and pepper until well coated.
Spread the vegetables evenly on the prepared baking sheets, making sure they're not overcrowded.
Roast for 25-30 minutes, stirring halfway through, until the vegetables are tender and lightly caramelized.
While the vegetables are roasting, bring a large pot of salted water to boil and cook the ziti according to package instructions until al dente.
Reserve 1 cup of pasta water before draining the ziti.
Return the pasta to the pot, add the roasted vegetables, and toss gently. Add a splash of reserved pasta water if needed to create a light sauce.
Stir in the Parmesan cheese and adjust seasoning to taste.
Serve hot, garnished with fresh basil leaves and additional Parmesan if desired.
