Bring a large pot of salted water to a boil. Add the penne and cook according to package instructions until al dente, about 8-10 minutes. Drain and set aside.

In a large skillet, heat olive oil over medium heat. Add ground turkey and cook until browned, about 5-7 minutes. Drain excess grease if necessary.

Stir in tomato sauce, half-and-half, and red chili flakes into the skillet. Simmer for 3-4 minutes until bubbling.

Add the drained penne to the skillet and mix thoroughly. Simmer for another 2-3 minutes to combine flavors.

Sprinkle in mozzarella and cheddar cheese, stirring until melted and creamy. Cook for another minute if needed.

Serve immediately, garnished with fresh parsley and additional chili flakes if desired.
