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; set aside.
02 - While the pasta cooks, warm the olive oil in a large skillet over medium heat. Add the chopped onion and sauté for about 3 minutes until softened and translucent. Stir in the minced garlic and cook for 1 minute until fragrant, being careful not to let it brown.
03 - Pour in the crushed tomatoes, sugar, dried oregano, and dried basil. Season generously with salt and freshly ground black pepper. Stir to combine, then let the sauce simmer uncovered for 10 to 12 minutes, stirring occasionally, until it thickens slightly and the flavors meld together.
04 - Add the drained pasta directly to the skillet with the tomato sauce. Toss well to coat every strand or piece evenly. If the sauce seems too thick, add a splash of the reserved pasta water, a little at a time, until it reaches your desired consistency.
05 - Divide the pasta among warm serving bowls. Finish with a generous sprinkle of grated Parmesan cheese and scatter fresh basil leaves over the top. Serve immediately while hot.
