Spray the crock pot insert with cooking spray. Add the halved baby carrots and chopped potatoes. Pour melted butter over and stir together to coat the vegetables.
Cut chicken breasts into bite-sized pieces. Sprinkle the salt and pepper over the chicken pieces and mix together. Add the chicken chunks into the crock pot with the vegetables.
In a small mixing bowl, add chicken broth, cream of chicken soup, sour cream, and dry ranch seasoning mix. Stir with a whisk and mix until well combined and creamy. Pour over the chicken/vegetables and stir everything together.
Cover with the lid and cook on LOW heat for 6-8 hours.
You can use some of both potatoes like I do if wanted. I peel off the bad parts of the skin and leave the rest on. You can peel the entire potato if that's what you prefer. I buy a bag of small baby potatoes so I only cut into quarters. If your potatoes are larger, just cut them into chunks (bite-sized pieces).
The first time I made this I used full salt chicken broth and it was way too salty! The low-sodium chicken broth is important.
I prefer to use full-fat sour cream but lite sour cream will work too.
