01 - Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Drain and set aside.
02 - Pat chicken breasts dry with paper towels. Season both sides generously with salt, pepper, and paprika.
03 - In a large skillet, heat olive oil over medium-high heat. Add chicken breasts and sear for 5-6 minutes per side until golden brown and cooked through (internal temperature reaches 165°F). Remove chicken, tent loosely with foil, and let rest for 5 minutes.
04 - Add minced garlic to the same skillet. Sauté for 30 seconds until fragrant, being careful not to burn. Add sliced sun-dried tomatoes and cook for 1 minute to release their oils.
05 - Pour in chicken broth, using a wooden spoon to scrape up any browned bits from the bottom of the pan. Let simmer for 2-3 minutes until slightly reduced.
06 - Lower heat to medium-low. Stir in heavy cream, grated Parmesan cheese, Italian seasoning, and red pepper flakes if using. Simmer for 3-4 minutes, stirring frequently, until sauce thickens enough to coat the back of a spoon.
07 - Slice rested chicken into strips. Return cooked pasta and sliced chicken to the skillet with the sauce. Toss everything together until well combined and heated through. Serve immediately, garnished with chopped fresh basil or parsley and additional grated Parmesan.
