Season the chicken breasts with salt, black pepper, garlic powder, paprika, and Italian seasoning.
Heat olive oil and butter in a large skillet over medium-high heat.
Sear the chicken for 5 to 6 minutes per side until golden brown. Remove from the skillet.
Add the minced garlic and cook for 30 seconds.
Pour in the chicken broth and scrape the browned bits from the bottom of the skillet.
Stir in the heavy cream, Parmesan cheese, sun-dried tomatoes, Italian seasoning, and red pepper flakes.
Simmer for 4 to 5 minutes until the sauce thickens slightly.
Return the chicken to the skillet and spoon the sauce over the top.
Cover and cook over low heat for 8 to 10 minutes until the chicken reaches an internal temperature of 165°F (74°C).
Garnish with fresh basil and extra Parmesan cheese before serving.
