01 - Cook pasta according to package directions. Reserve ½ cup pasta water before draining. Set drained pasta aside.
02 - Pat chicken breasts thoroughly dry with paper towels. Season both sides evenly with salt, black pepper, and Italian seasoning.
03 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add chicken and cook for 5–6 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to a plate, rest for 5 minutes, then slice into thin strips.
04 - In the same skillet, reduce heat to medium. Melt butter and add minced garlic. Sauté for 1 minute until fragrant, being careful not to burn.
05 - Pour in heavy cream and chicken broth, stirring to combine. Bring to a gentle simmer. Whisk in Parmesan cheese until completely melted and smooth.
06 - Stir in sun-dried tomatoes and crushed red pepper flakes. Simmer for 2–3 minutes until slightly thickened.
07 - Add sliced chicken and cooked pasta to the skillet. Toss thoroughly to coat. Add reserved pasta water as needed to achieve desired creamy consistency. Remove from heat, fold in fresh basil, and serve immediately with additional Parmesan and basil garnish.
