Turn the instant pot on to saute and put the butter in the pan to melt.
Combine the paprika, salt, mustard powder, garlic powder, onion powder and pepper together in a ziplock bag and shake.
Add the chicken to the bag and shake till all the chicken is coated.
Add the chicken to the melted butter and saute for 2 minutes.
Add the chicken stock and the pasta to the pan and stir.
Place the lid on the pan, making sure the vent is sealed.
Set the instant pot to high pressure for 3 minutes.
It will take a little bit for the pressure to build up, and the food will be cooking while the pressure builds.
When the timer is finished, do a quick release and carefully open the pot.
