- Liberally season the chicken breasts with garlic powder, salt, & pepper. Set aside. - 1 1/2- 2  lbs boneless skinless chicken breasts, garlic powder, salt & pepper 
- To the crock, add the gravy powders, condensed soup, & two cups of water. Whisk until the mixture's smooth.  - 1 .87 oz packet brown gravy mix, 1 .87 oz packet mushroom gravy mix, 1 10.5 oz can golden mushroom condensed soup, 2 cups water 
- Add the chicken breasts to the crock, spreading them out so they're all equally bathed in the gravy mixture. 
- Cover, and cook the chicken on low for 6-8 hours. 
- Remove the cooked chicken to a cutting board, and using two forks or meat claws shred the meat. 
- After you've removed the chicken, but before you get to shredding, whisk together the cornstarch and water to form a slurry. Whisk this into the gravy, and turn the heat to high. - 1 1/2 tbsp cornstarch, 1 tbsp cold water 
- Return the chicken to the pot, stirring to mix it in with the gravy. Cover and let the mixture cook an additional ten minutes to thicken the gravy slightly. 
- Serve the chicken over rice, mashed potatoes, or thick pieces of toasted white bread.
