01 - Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente. Drain thoroughly and set aside.
02 - Pat chicken breasts dry with paper towels. Season both sides generously with kosher salt, black pepper, and paprika, pressing seasoning into the meat.
03 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and sear for 5-6 minutes per side until golden brown and cooked through (internal temperature reaches 165°F). Remove from skillet, tent loosely with foil, and let rest for 5 minutes.
04 - Add minced garlic to the same skillet, stirring constantly for 30 seconds until fragrant. Add 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 skillet. Let simmer for 2-3 minutes until slightly reduced.
06 - Reduce heat to medium-low. Stir in heavy cream, grated Parmesan cheese, Italian seasoning, and red pepper flakes. Simmer for 3-4 minutes, stirring occasionally, until sauce thickens enough to coat the back of a spoon.
07 - Slice rested chicken into strips. Return pasta and chicken to the skillet with sauce, tossing gently until well combined and heated through. Serve immediately, garnished with fresh basil or parsley and additional Parmesan cheese.
