01 - Bring a large pot of generously salted water to a rolling boil. Add pasta and cook according to package directions until al dente. Drain through a strainer, reserving ½ cup of the starchy pasta water. Set aside.
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. Add the minced garlic and cook for 1 additional minute, stirring to prevent browning.
03 - Stir in the crushed tomatoes, sugar, dried oregano, and dried basil. Season with salt and freshly ground black pepper to taste. Reduce the heat to medium-low and simmer uncovered for 10 to 12 minutes, stirring occasionally to prevent sticking.
04 - Add the drained pasta to the skillet with the tomato sauce. Toss thoroughly to coat every strand or piece. Add a splash of the reserved pasta water as needed to loosen the sauce and help it cling to the pasta.
05 - Divide among plates and serve immediately while hot. Finish with freshly grated Parmesan cheese and a scattering of torn basil leaves.
