01 - Place the chicken breasts in an even layer across the bottom of the slow cooker.
02 - In a medium mixing bowl, whisk together the heavy cream, chicken broth, softened cream cheese, grated Parmesan, minced garlic, dried Italian herbs, salt, black pepper, and crushed red pepper flakes until smooth and well combined.
03 - Fold the sliced sun-dried tomatoes into the cream sauce mixture.
04 - Pour the sauce evenly over the chicken breasts, ensuring they are fully submerged.
05 - Cover the slow cooker and cook on LOW for 4 to 5 hours, or until the chicken is tender and reaches an internal temperature of 165°F.
06 - Shred the chicken directly in the sauce using two forks, or serve the breasts whole. Garnish with fresh basil and serve alongside mashed potatoes, rice, or pasta.
