In the same pan, add butter. Once melted, whisk in the flour and cook for 30–40 seconds, stirring constantly to remove the raw taste (do not brown). Add the heavy whipping cream and mix well. Stir in salt, garlic powder, black pepper, Italian seasoning, and dried parsley. Simmer gently for 3–4 minutes, stirring, until slightly thickened.

Slice the chicken and add to the pasta. Toss again and simmer on low heat for 1–2 minutes to combine flavors. Garnish with extra Parmesan, parsley, or a pinch of black pepper as desired. Optionally, drizzle olive oil or butter on top for added gloss.
