In a large bowl, mix together the salt, pepper, garlic powder, onion powder, Italian Seasoning, and smoked paprika. Add 1 tablespoon of olive oil to the bowl. Mix to combine.
Add the frozen chicken thighs to the bowl and mix to coat the chicken thighs.
Place the trivet insert or steamer basket insert into the bottom of the Instant Pot.
Add one cup of water to the bottom of the pot. This will create steam for the chicken to cook in.
Add the chicken thighs to the top of the trivet insert or steamer basket. Try to keep the chicken thighs in a single layer, but if they overlap a bit that's ok. Pour any remaining seasoning mixture onto the top of the chicken.
Close the lid of the Instant Pot and set the cooking time to 25 minutes on high pressure. Make sure the vent is set to sealing position.
After 25 minutes of cook time, quick release the steam to release any remaining pressure.
Set your broiler to high. Carefully open the lid of the Instant Pot and place the chicken thighs on a baking sheet. Broil the chicken thighs for 5 minutes or until the skins are golden browned and crispy. Serve immediately.
