Season the chicken with Italian seasoning, salt, and pepper.
Cook the chicken in a hot skillet until golden and cooked through, then transfer it to a plate.
Add minced garlic to the same pan and cook briefly until fragrant.
Add chicken broth, heavy cream, Parmesan, and sun-dried tomatoes and stir until creamy.
Place the chicken back into the sauce and simmer gently until warmed through and coated.
Adjust the seasoning and sprinkle with fresh basil if desired.
Spoon the creamy sauce over the chicken and serve warm with pasta, rice, potatoes, or vegetables.
