Wash and slice your artichokes in half length-wise.
Scoop the hairy insides out of each artichoke and throw them away. Remove the small outer leaves. Cut the sharp tips off of the artichoke leaves with scissors, then rinse the halves.
Set a steamer insert in the Instant Pot, add the water, then arrange the artichoke halves in a single layer, stem side down. Spray the cut surfaces of the artichokes with olive oil. You can optionally add some fresh lemon juice for flavor.
Close the Instant Pot lid and cook on High Pressure for 15 minutes. Use a natural pressure release for 10 minutes, then quick release the rest of the pressure.
Serve the artichokes with one of your favorite dips.
