01 - Cook pasta according to package directions. Reserve ½ cup of 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 for 5–6 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to a plate and rest for 5 minutes, then slice into thin strips.
04 - In the same skillet, melt butter over medium heat. Add minced garlic and 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 completely melted and smooth. Stir in sun-dried tomatoes and red pepper flakes. Simmer for 2–3 minutes until slightly thickened.
07 - Add sliced chicken and cooked pasta to the skillet. Toss everything together until well coated. Add reserved pasta water as needed to achieve desired creaminess. Remove from heat, stir in fresh basil, and serve immediately with additional Parmesan and basil garnish.
