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.
02 - In a large skillet, heat olive oil over medium heat. Add garlic and onion, sautéing until soft and translucent, about 5 minutes.
03 - Stir in crushed tomatoes, dried oregano, dried basil, sugar, salt, and pepper. Bring to a simmer and cook uncovered for 12–15 minutes, stirring occasionally to develop depth of flavor.
04 - Add the drained pasta directly into the sauce, tossing to coat evenly. Gradually incorporate reserved pasta water until the desired consistency is reached.
05 - Serve immediately while hot, finished with freshly grated Parmesan cheese and a scattering of torn basil leaves.
