Method :

1. Cook penne pasta according to package directions until al dente. Drain, reserving about 1 cup of pasta water.
2. While the pasta cooks, heat olive oil in a large skillet over medium heat.
3. Add the Italian sausage and cook, breaking it up with a spoon, until browned. Drain off any excess grease.
4. Add the chopped onion to the skillet and cook until softened, about 5 minutes.
5. Stir in the minced garlic and cook for 1 minute until fragrant.
6. Pour in the crushed tomatoes. Add the dried oregano and red pepper flakes (if using).
7. Season with salt and black pepper to taste. Bring to a simmer, then reduce heat and cook for 15-20 minutes, stirring occasionally, allowing the sauce to thicken.
8. Stir in the grated Parmesan cheese until melted and well combined.
9. Add the drained penne pasta to the skillet with the sauce.
10. Toss to coat the pasta evenly. If the sauce is too thick, add a little reserved pasta water to reach desired consistency.
11. Serve immediately, garnished with extra Parmesan cheese and fresh basil, if desired.
