Press the Sauté button on your Instant Pot and add the chopped onion. Sauté, stirring occasionally, until the onion begins to soften, about 5 to 8 minutes.
Stir in the minced garlic, chili powder, ground cumin, paprika, dried oregano and sea salt. Allow this mixture to cook for 1 to 2 minutes to let the flavors of the spices open up.
Secure the lid on the Instant Pot, press ‘Manual’ or ‘Pressure Cook’ and set the time for 15 minutes. Make sure the pressure release valve is set to the ‘Sealing’ or closed position.
