Place the chicken breasts and broth into a slow cooker that is at least 6 quarts.
Sprinkle the salt, black pepper, garlic powder, and any other preferred seasonings evenly over the chicken.
Cover the slow cooker and cook on the low heat setting for 4 to 6 hours until the chicken is fully cooked and can be shredded easily.
Take the chicken out of the slow cooker and transfer it to a cutting board or a pan with edges.
Shred the chicken using two forks, shredding claws, or a meat shredder tool.
Return the shredded chicken back to the slow cooker and mix it well with the cooking juices.
Let the chicken cool and then store it in an airtight container or zip-top bag in the fridge for up to 4 days or freeze it for up to 3 months.
Use this shredded chicken in various dishes such as salads, soups, chicken salads, or casseroles whenever needed.
