The first time I shredded chicken with a fork - while making crockpot buffalo chicken - it could not have been messier or more time consuming. So the next time I stumbled upon a recipe requiring shredded chicken (for example, baked buffalo chicken rolls), I threw the cooked breasts in my KitchenAid mixer, set it to a medium to high speed, and shred away.
Just don't forget to lock your mixer and put any juice in after the meat is shredded, or else you risk splashing everywhere. Yes, that happened to me when making Hawaiian barbecue chicken.
In this example I separated the chicken a bit beforehand, but you really don't even need to do that. I now just throw entire cooked breasts into my KitchenAid mixer and then shred.
Hope you enjoy this quick tip the next time your needing shredding chicken!
