Step 1: Begin by boiling a large pot of salted water. Add the pasta and cook according to package instructions until al dente, then drain and set aside.

Step 2: In a large skillet, heat the olive oil over medium heat. Season the sliced chicken breasts with salt and pepper.

Step 3: Sear the chicken in the skillet until golden brown and cooked through, about 5-7 minutes. Remove chicken from the skillet and set aside.

Step 4: In the same skillet, add minced garlic and chopped sun-dried tomatoes. Sauté until fragrant, about 1 minute.

Step 5: Pour in the chicken broth and heavy cream, stirring to combine. Bring the mixture to a gentle simmer.

Step 6: Stir in Parmesan cheese, Italian seasoning, and crushed red pepper flakes. Let the sauce thicken for about 3-4 minutes.

Step 7: Add the seared chicken and cooked pasta to the skillet. Toss everything together until well coated in the sauce.

Step 8: Garnish with fresh basil and additional Parmesan cheese before serving.
