It's so easy to make Chicken & Dumplings in the Instant Pot! Add the chicken, onion and chicken broth then set for 5 minutes and natural release.
Remove the chicken to cool a little bit before chopping or shredding. While the chicken is cooling, let the broth come to a low boil to begin cooking the dumplings.
I used a can of crescent rolls and pulled off small pieces. If you really love the dumplings, you can add two cans. Add only two or three pieces at a time, to keep them from sticking.
Return the chicken to the broth. Add the pimientos and a cornstarch slurry to thicken it up a little bit. Serve as soon as it reaches the consistency you like.
