In a small bowl, combine all of the dried spices. Mix together well.
Place the salmon fillets on a plate and pat dry with a paper towel.
Coat the salmon filets evenly in the seasoning mix. Sprinkle both sides generously, covering every inch of the salmon. You may have some seasoning left over which you can save for another day.
Add the olive oil to the Instant Pot and press the ‘saute’ button. Let the oil heat for one minute then add the seasoned salmon into the hot oil. Sear on each side for 2 minutes.
Remove the salmon filets from the Instant Pot and place them on a piece of foil. Wrap the foil around the salmon, enclosing it completely.
Pour one cup of water into the bottom of the Instant Pot bowl that still has the olive oil and seasonings in the bottom (no need to wash the bowl!). Place the trivet into the pot as well.
Put the foil wrapped salmon filets on top of the trivet and then place the lid on the Instant Pot bowl, setting the steamer valve to ‘seal’. Press the ‘manual’ button and set the timer for 5 minutes on high pressure. When the time is complete, let the pressure naturally release which means just let the pot sit until you are able to open the lid! This should take about 10 minutes.
Unwrap the blackened salmon and serve while hot. Enjoy!
