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 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. Sauté for 30 seconds until fragrant, being careful not to burn. Add sliced sun-dried tomatoes and cook for 1 minute to soften.
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 constantly, until sauce thickens enough to coat the back of a spoon.
07 - Slice rested chicken into strips. Add cooked pasta and chicken slices to the sauce, tossing until well combined and heated through. Serve immediately, garnished with chopped fresh basil or parsley and additional grated Parmesan.
