Using a large mixing bowl, place the beef short ribs in the bowl and add the garlic powder, onion powder, ground ginger, pepper and salt and rub this mixture all over the short ribs. Place the rack insert into the inner cooker pot of your instant pot and pour in 1 cup of water.
Place the beef ribs onto the rack, so they are sitting on the rack above the water.
Put the instant pot lid on, make sure the valve is in the sealed position, then cook on high pressure for 30 minutes. Please note, it will take about 5 to 10 minutes or so for your instant pot to come to pressure. When finished, let the pressure naturally release for 10 minutes (do not open the valve for 10 minutes after the 30 minute cook time is over). Once it’s released naturally for 10 minutes, finish with a quick release (open the valve).
