Spray the inside of your slow cooker with cooking spray or grease lightly with butter.
Season the chicken thighs with sea salt, black pepper, garlic powder, and onion powder. Place them in an even layer.
In a bowl, whisk together the cream of chicken soup and chicken broth until smooth. Pour over the seasoned chicken.
Dot the cubed cream cheese and butter evenly across the top.
Cover and cook on LOW for 6 hours, or until the chicken is fork-tender and the sauce is creamy.
Before serving, shred the chicken directly in the pot and stir to combine with the sauce.
Garnish with fresh parsley and enjoy over pasta, rice, or mashed potatoes.
