01 - Cook bowtie pasta in salted boiling water until al dente according to package directions. Drain thoroughly, reserving 1/2 cup pasta water for later use.
02 - Season bite-sized chicken pieces with 1/2 teaspoon salt, 1/4 teaspoon black pepper, and 1 teaspoon Italian seasoning, ensuring even coating on all sides.
03 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add seasoned chicken and cook for 6–7 minutes until golden brown and cooked through. Transfer to a plate and set aside.
04 - In the same skillet, melt 3 tablespoons butter over medium heat. Add minced garlic and sauté for 1 minute until fragrant, being careful not to burn.
05 - Pour in 1 cup heavy cream and 1/2 cup chicken broth, stirring constantly to combine. Bring mixture to a gentle simmer.
06 - Stir in 1 cup shredded mozzarella and 1/2 cup grated Parmesan until completely melted and sauce has thickened, approximately 3–4 minutes. Season with salt, pepper, and red pepper flakes if desired.
07 - Return cooked chicken to the skillet, add prepared pasta, and toss thoroughly to coat. Add reserved pasta water gradually if sauce needs thinning. Remove from heat, garnish with fresh parsley, and serve immediately.
