01 - Prepare bowtie pasta in salted boiling water according to package directions until al dente. Drain thoroughly, reserving 1/2 cup of the starchy pasta water for sauce adjustment.
02 - Pat chicken pieces dry and season evenly with salt, freshly ground black pepper, and Italian seasoning blend.
03 - Heat olive oil in a large skillet over medium-high heat. Add seasoned chicken in a single layer and cook until golden brown on all sides and cooked through, approximately 6–7 minutes. Transfer chicken to a plate and set aside.
04 - In the same skillet, reduce heat to medium and melt butter. Add minced garlic and sauté for 1 minute until fragrant, being careful not to burn.
05 - Pour in chicken broth and heavy cream, stirring continuously to incorporate. Bring the mixture to a gentle simmer.
06 - Gradually add mozzarella and Parmesan cheeses while stirring constantly. Simmer for 3–4 minutes until sauce thickens and becomes smooth. Season with salt, pepper, and optional red pepper flakes.
07 - Return cooked chicken to the skillet along with drained pasta. Toss everything together thoroughly, adding reserved pasta water gradually if sauce consistency is too thick. Remove from heat, garnish with fresh parsley, and serve immediately.
