Once you’ve made your Instant Pot chicken breast, it should already be very tender and easy to shred. You can use these methods to do so:
Two Forks – You can use forks to shred chicken breast directly in the Instant Pot. Hold a piece of chicken steady with one fork, then pull and tear away the shredded pieces with the other fork. Repeat the process until all your chicken is shredded. (You can also use meat shredding claws like this, which work the same way as forks but faster, since they are larger and have more tines.)
Hand Mixer – A hand mixer is faster than using forks, and you can use it directly in the Instant Pot as well. Drain some of the liquid temporarily, to prevent splattering, then place the beaters into the Instant Pot and turn on the mixer to shred. If your hand mixer has a slow start feature, like this one that I have, that is helpful to reduce splattering.
Stand Mixer – A stand mixer works the same way as a hand mixer, except you’ll need to transfer the chicken into the mixer bowl.
