01 - Bring a large pot of generously salted water to a rolling boil. Add the pasta and cook according to package directions until al dente. Drain through a colander, reserving ½ cup of the starchy pasta water.
02 - While the pasta cooks, warm 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 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, until it thickens slightly.
04 - Add the drained pasta to the skillet with the tomato sauce and toss thoroughly to coat every strand or piece. If the sauce seems too thick, add a splash of the reserved pasta water to reach the desired consistency.
05 - Divide the pasta among serving bowls. Finish with a generous sprinkle of grated Parmesan cheese and a few torn fresh basil leaves. Serve immediately while hot.
