Two ways: stand mixer or two forks

The quickest and most efficient way to shred chicken is in a stand mixer, such as a Kitchen Aid.  First, bake chicken or poach/simmer in a pot for about 20-25 minutes, then while hot, add to a stand mixer with the paddle attachment.  Turn on and let the machine do the work for you!  (Cook chicken until internal temperature 165 F.)  You will have beautiful shredded chicken you can use for many meals – like in my post Batch Cook Proteins For More Meals
