Step 1: Place the chicken breasts at the bottom of your crockpot and season with salt, pepper, and optional thyme and parsley.
Step 2: In a bowl, whisk together the cream of chicken soup, cream of mushroom soup, chicken broth, sour cream, and milk until smooth. Pour this mixture over the chicken.
Step 3: Evenly sprinkle the stuffing mix over the soup layer, then drizzle melted butter on top to add flavor.
Step 4: Cover and cook on **low** for 6-7 hours or on **high** for 3-4 hours, until the chicken is tender and thoroughly cooked.
Step 5: Before serving, shred the chicken into the mixture for a creamy, blended texture.
