Cook the fus-illi:

1. • Bring a large pot of salted water to a boil. Add the fus-illi pasta and cook according to the package instructions until al dente (7-10 minutes). Drain and set aside.

   

Prepare the sauce:

1. • As the pasta is cooking, warm some olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Stir in the minced garlic and sauté for 1-2 minutes until it becomes aromatic.

Add the tomatoes and seasonings:

1. • Add the crushed tomatoes, oregano, red pepper flakes, salt, and pepper. Lower the heat and allow the sauce to simmer gently for 10-15 minutes, stirring occasionally.

Combine pasta and sauce:

1. • Add the cooked fus-illi to the sauce and toss to coat. Stir in the chopped fresh basil, and adjust seasoning if needed.

Serve

1. 1. Serve hot, topped with grated Parmesan cheese and garnished with extra fresh basil leaves if desired.
