In a mixing bowl, combine the cream of chicken soup, ranch dressing mix, and chicken broth. Stir until smooth.
Place the chicken breasts at the bottom of the crockpot. Season with salt and pepper to taste.
Pour the soup mixture evenly over the chicken breasts in the crockpot.
Cover the crockpot and cook on low for 6-7 hours or on high for 3-4 hours until the chicken is tender and fully cooked.
About 30 minutes before serving, stir in the sour cream and sprinkle the shredded cheddar cheese over the top. Replace the lid and continue cooking until the cheese is melted and bubbly.
Once finished, shred the chicken in the crockpot using two forks and mix it with the sauce.
Notes
Serve the angel chicken over cooked rice or mashed potatoes, drizzling some of the creamy sauce over the top. Garnish with fresh chives for added color and flavor.
