Add chicken thighs to pot. Then add ranch packet on top of chicken, followed by chicken broth. Gently mix the broth until seasoning has dissolved.
Lock lid and cook for 10 minutes at high pressure.
Meanwhile, make the sauce... Add mayonaise to a mixing bowl. Then add all the herbs and spices - chives, parsley, dill, onion powder, garlic powder, salt, and pepper. Mix together and set aside.
Once cook time is complete, allow pressure to release naturally for at least 10 minutes. Then quick-release remaining pressure.
Transfer chicken to a bowl and place in freezer for a few minutes to cool them down quickly.
Now, this is not part of the recipe, but I would recommend using this broth to cook some rice or quinoa.
Place chicken on a cutting board and finely chop. Then return chicken to bowl.
Top with ranch sauce and mix until well combined. Chill in the refrigerator until ready to serve.
