Start by seasoning the chicken breasts with salt and pepper. Place chicken in the bottom of the crockpot.

In a mixing bowl, combine the creamy parmesan sauce ingredients: heavy cream, parmesan cheese, minced garlic, and sun-dried tomatoes. Whisk until smooth.

Pour the sauce mixture over the seasoned chicken in the crockpot, ensuring it's well-covered.

Cover the crockpot and cook on low for 6-8 hours, or on high for 4 hours, until chicken is fork-tender.

Once cooked, shred the chicken if preferred and serve over pasta or rice.
