Place the chicken breasts in the slow cooker.
Season the chicken with salt, pepper, and any additional seasonings of your choice.
Pour chicken broth or water over the chicken breasts until they are partially submerged in liquid.
Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the chicken is cooked through and tender.
Once cooked, remove the chicken from the slow cooker and transfer it to a cutting board.
Use two forks to shred the chicken into bite-sized pieces.
Serve immediately or use the shredded chicken in your favorite recipes.
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days, or freeze for future use.
