Pour chicken broth into the slow cooker. Place chicken in the slow cooker and sprinkle with salt, pepper and garlic powder. *If using frozen chicken, you do not need the chicken broth.
Cook on high for 3 1/2-4 hours or on low for 5 hours. Shred chicken with two forks.
Return shredded chicken to the slow cooker and cook for an additional 30 minutes on low. This step helps to keep the chicken moist and tender and adds a little more flavor.
Divide chicken into 2 cup (or more/less, depending on your needs) portions and place into freezer bags and store in the freezer for up to 4 months. Add chicken to sandwiches, soups, tacos and casseroles!
Nutritional information is based on 1 cup portions. Depending on the recipe this will feed 2-3 people.
