01 - Cook bowtie pasta in salted boiling water until al dente according to package directions. Drain thoroughly, reserving 1/2 cup of pasta cooking water for later use.
02 - Pat chicken pieces dry with paper towels. Season generously with salt, black pepper, and Italian seasoning, ensuring even coating on all sides.
03 - Heat olive oil in large skillet over medium-high heat until shimmering. Add seasoned chicken in single layer. Cook undisturbed for 3-4 minutes until golden brown, then flip and continue cooking until chicken reaches internal temperature of 165°F, about 3 additional minutes. Transfer to plate and tent with foil.
04 - Reduce heat to medium. Add butter to same skillet, allowing to melt and foam. Add minced garlic and sauté constantly for 60 seconds until fragrant but not browned.
05 - Pour in chicken broth and heavy cream, stirring to deglaze pan and incorporate browned bits. Bring mixture to gentle simmer, stirring occasionally.
06 - Reduce heat to low. Gradually whisk in mozzarella and Parmesan cheeses until completely melted and sauce is smooth and velvety, about 3-4 minutes. Season with salt, pepper, and red pepper flakes to taste.
07 - Return cooked chicken to skillet. Add drained pasta and toss everything together gently. If sauce appears too thick, add reserved pasta water one tablespoon at a time until desired consistency is reached. Remove from heat immediately.
08 - Transfer to serving platter or individual bowls. Sprinkle generously with fresh chopped parsley. Serve immediately while hot.
