Place the chicken breasts in a large pot, ensuring they are of even size and thickness for uniform cooking. If necessary, slice any thicker pieces for evenness.
Pour chicken broth over the chicken to fully cover it.
Heat the pot over medium-high heat and bring the chicken and broth to a rolling boil.
Reduce the heat to a simmer and cover the pot with a lid.
Let the chicken cook until it's no longer pink inside and the internal temperature reads 165°F. This usually takes about 15-20 minutes, depending on thickness. Avoid overcooking to keep the chicken tender.
Remove the chicken from the broth and shred it with two forks or use a stand mixer for quick shredding. The chicken is now ready to be used in your favorite dishes.
