01 - Bring a large pot of salted water to a rolling boil. Add the pasta and cook until al dente according to package directions. Reserve ½ cup of starchy pasta water before draining through 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 deep flavor.
04 - Transfer the drained pasta directly into the skillet with the sauce. Toss thoroughly, adding splashes of the reserved pasta water as needed to reach your preferred consistency.
05 - Serve immediately while hot, finished with a generous shower of freshly grated Parmesan cheese and torn basil leaves.
