In a large skillet, heat olive oil over medium-high heat. Add chicken and cook until browned and cooked through, about 6–8 minutes. Remove from skillet and set aside.
4. Make the roux
In the same skillet, melt butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
5. Whisk in flour
Sprinkle in the flour and whisk continuously for 1–2 minutes to form a roux.
6. Add liquids
Gradually whisk in the milk and chicken broth, stirring constantly to avoid lumps. Bring to a gentle simmer.

Add cream cheese and 1 cup of mozzarella, stirring until melted and smooth.
8. Mix in cheese and seasoning

9. Combine chicken and sauce
Add cooked chicken back into the sauce and simmer for 2–3 minutes to heat through.
10. Toss with spaghetti
Add cooked spaghetti to the skillet and toss to coat in the sauce.
11. Melt remaining cheese

12. Serve
Serve hot, garnished with fresh parsley or extra Parmesan if desired.
