Bring a pot of salted water to a boil and cook your pasta el dente. Reserve about 1 cup of the pasta water, then drain.
While the pasta is cooking, heat the olive oil in a large skillet, over medium heat. Add the garlic and saute until soft and fragrant- don’t let it brown.
Add the tomatoes, red pepper flakes and a pinch of salt and cook 5-6 minutes until the tomatoes are soft and blistered
Add the zucchini and cook until tender 4-5 minutes. Add the marinara sauce and the reserved pasta water and cook 5 minutes longer.
Add the drained pasta to the pan. Toss everything together until well coated and glossy. Stir in the parmesan cheese and stir to melt into the sauce
Serve hot with fresh basil leaves and additional parmesan cheese.
