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
If you have too much shredded chicken – making big batches is the way to go – refrigerate and freeze in portioned ziploc baggies. Save for meals like taco bowls, tacos, enchiladas, lasagna, casseroles, pot pies, salads, soups, etc.
If you don’t have a stand mixer (I didn’t have one for years!), no problem – use two forks EASY. Place the cooked chicken on a cutting board or bowl and start shredding!
