01 - Pat the chicken breasts dry and season both sides evenly with salt, black pepper, garlic powder, and smoked paprika.
02 - Heat olive oil in a large skillet over medium-high heat. Sear the chicken breasts for 5 to 6 minutes per side until golden brown and cooked through to an internal temperature of 165°F. Transfer to a plate and let rest.
03 - While the chicken rests, cook the pasta in a large pot of generously salted boiling water until al dente according to package directions. Reserve 1/2 cup of the starchy pasta water before draining.
04 - In the same skillet used for the chicken, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute, scraping up any browned bits from the bottom of the pan.
05 - Stir in the sliced sun-dried tomatoes and cook for 2 minutes, allowing their concentrated flavor to bloom in the butter.
06 - Pour in the heavy cream and chicken broth, stirring to combine. Bring the mixture to a gentle simmer over medium heat.
07 - Add the Parmesan cheese, Italian seasoning, and red pepper flakes. Stir continuously until the cheese melts and the sauce thickens, about 2 to 3 minutes. Season with salt and pepper to taste.
08 - Slice the rested chicken into strips. Add the drained pasta and sliced chicken back into the skillet, tossing everything together until evenly coated. Use the reserved pasta water to adjust the sauce consistency as needed. Serve immediately, garnished with fresh basil and additional grated Parmesan.
