01 - Bring a large pot of salted water to a rolling boil. Add the pasta and cook until al dente, following the package directions. Reserve ½ cup of starchy pasta water before draining in a colander.
02 - While the pasta cooks, warm olive oil in a large skillet over medium heat. Add the garlic and onion, sautéing until softened and translucent, approximately 5 minutes.
03 - Stir in the crushed tomatoes, dried oregano, dried basil, sugar, salt, and pepper. Bring to a gentle simmer and cook uncovered for 12 to 15 minutes, stirring occasionally to develop a rich, savory flavor.
04 - Add the drained pasta directly to the skillet with the sauce, tossing to coat evenly. Splash in the reserved pasta water as needed to reach your preferred consistency.
05 - Transfer to warmed plates or a serving dish. Finish with a generous shower of freshly grated Parmesan cheese and scatter torn basil leaves over the top. Serve immediately while hot.
