Add 2 cups water into the steel inner pot, then place a steamer basket or the wire rack that came with your pressure cooker into the pot.
Place the unpeeled beets on top of the rack, then secure the lid, close the pressure valve, and cook for 15 minutes at high pressure.
Open the valve to quick release any remaining pressure.
Once the the beets are cool enough to touch, remove them from the pot. The peels should easily slide off.
Place the beets on a cutting board and chop them into the desired size.
