01 - Bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package directions until al dente. Drain through a strainer, reserving ½ cup of the starchy pasta water for later use.
02 - While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3 minutes until soft and translucent. Stir in the minced garlic and cook for 1 minute until fragrant.
03 - Pour in the crushed tomatoes, sugar, dried oregano, and dried basil. Season with salt and freshly ground black pepper to taste. Stir to combine and let the sauce simmer uncovered for 10 to 12 minutes, stirring occasionally to prevent sticking.
04 - Add the drained pasta directly to the skillet with the tomato sauce. Toss everything together thoroughly, adding a splash of the reserved pasta water as needed to loosen the sauce and help it cling to the noodles.
05 - Divide among plates and serve immediately while hot. Finish with a generous sprinkle of grated Parmesan cheese and torn fresh basil leaves on top.
