Gather all your ingredients. Combine dry seasonings together in a bowl.
Thoroughly season the chicken thighs on both sides.
Turn on your Instant Pot to the sauté setting. Drizzle olive oil into the bottom of the pot. Brown the outside of the chicken thighs until golden. Remove the chicken and set aside.
Cut the onion into half rings. Sauté onion until golden brown. Add browned chicken on top of the browned onions.
Set the timer to manual for 10 minutes. Once the Instant Pot beeps, allow it to do a natural release for an additional 10 minutes. Carefully release any remaining pressure from the valve by covering it with a towel and turning it slowly. Once the pressure pin drops, safely remove the lid. Serve chicken hot, accompanied by your favorite sides.
Note: You can add 1/4 of a cup of water if you feel nervous about not adding liquid to the instant pot.
