Peel the rutabaga with a vegetable peeler.
Carefully cut the whole rutabaga in half with a sharp knife, and then cut the halves into 2 inch cubes.
Place the cubes of rutabaga into a bowl filled with cold water as you peel and cube it to keep it from browning.
Place a steamer basket or silicone sling into the bottom of the Instant Pot inner pot.
Drain the cubes rutabaga in a colander and run cold water over the pieces to remove all of the food grade wax pieces.
Pour the cubed rutabaga into the Instant Pot inner pot.
Twist the lid on and set the valve to the sealing position.
Press the manual button and set the pressure cooking time to 4 minutes.
When the timer goes off allow the to steam to naturally release for 10 minutes. Twist the valve to the releasing position and allow any remaining steam to release.
Carefully twist the IP lid off and lift it away from your face to prevent a steam burn.
Lift the silicone sling by the handles and transfer the cooked rutabaga to a bowl by tilting the silicone sling or steamer basket (if using) over a large bowl. If you have used the trivet that came with the Instant Pot you will need to use a large spoon to transfer the cooked rutabaga pieces to the bowl.
Use the cooked rutabaga in your recipe.
Makes about 5 cups cubes cooked, cubed rutabaga.
