Remove the tube of polenta from the wrapping and pat dry with a paper towel to remove as much moisture as possible.
Slice polenta into pieces that resemble the size and shape of steak fries.
When your air fryer is hot, it will beep when it's ready to add food, layer the wedges of your raw truffle polenta fries in the air fryer basket. Be careful that your fries don't touch each other. Do it in two separate batches if you have to. But because of how air fryers work, you want space between food so the air can circulate. Spray with olive oil spray on all sides, tossing to ensure that every side is coated. Sprinkle liberally with truffle salt.
Air fryer for 20 minutes, tossing once when your air fryer beeps. Add your cheese one or two minutes before your polenta fries are done to give it time to melt but not enough time to burn.
Finally, drizzle with truffle oil, serve with your favorite dipping sauce, or eat plain. They are that good!
