01 - Bring a large pot of salted water to a rolling boil. Add the pasta and cook until al dente, following package directions. Reserve ½ cup of starchy pasta water before draining.
02 - While the pasta cooks, heat olive oil in a large skillet over medium heat. Add the garlic and onion, sautéing until softened and translucent, about 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 12–15 minutes, stirring occasionally to meld the flavors.
04 - Add the drained pasta directly to the skillet with the sauce. Toss thoroughly, adding reserved pasta water a splash at a time until the sauce coats the pasta evenly.
05 - Transfer to warm plates and finish with freshly grated Parmesan cheese and torn basil leaves. Serve immediately.
