01 - Cook pasta according to package directions. Reserve ½ cup pasta water before draining. Set aside.
02 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, black pepper, and Italian seasoning.
03 - Heat olive oil in a large skillet over medium-high heat. Add chicken and cook 5–6 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to a plate and rest 5 minutes before slicing into thin strips.
04 - In the same skillet, reduce heat to medium. Melt butter and add minced garlic. Sauté until fragrant, about 1 minute.
05 - Pour in heavy cream and chicken broth. Bring to a gentle simmer, stirring constantly.
06 - Whisk in grated Parmesan cheese until fully melted and sauce is smooth. Add sun-dried tomatoes and crushed red pepper flakes. Simmer for 2–3 minutes until slightly thickened.
07 - Return sliced chicken to the skillet. Add cooked pasta and toss until evenly coated. Add reserved pasta water as needed to achieve desired creamy consistency. Remove from heat, stir in fresh basil, and serve immediately with additional Parmesan and basil garnish.
