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, reserving ½ cup of the starchy pasta water for later use.
02 - While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the chopped onion and sauté for 3 minutes until softened and translucent. Stir in the minced garlic and cook for 1 additional minute until fragrant.
03 - Pour in the crushed tomatoes, sugar, dried oregano, and dried basil. Season generously with salt and freshly ground black pepper. Stir to combine and let the sauce simmer uncovered for 10 to 12 minutes, stirring occasionally until it thickens slightly.
04 - Add the drained pasta directly to the skillet with the tomato sauce. Toss everything together thoroughly, adding small splashes of the reserved pasta water as needed to coat the noodles evenly and loosen the sauce to your preferred consistency.
05 - Divide among plates and serve immediately while hot. Finish each portion with a generous sprinkle of grated Parmesan cheese and a few torn fresh basil leaves.
