Roast the beets in the air fryer - Using your hands, rub the whole beets with some olive oil and wrap the beets together in a foil packet. Cook in the air fryer for 60 minutes at 400℉.
Toss the beets with the balsamic glaze and return to the air fryer - Once the beets have cooled, slip them out of their skins, and chop them into bite-sized cubes. Drizzle the cubes with the balsamic glaze, and toss. Return to the air fryer, loosely wrapped in the foil, for another 10 minutes or so.
Garnish and serve - Garnish with crumbled goat cheese and a generous handful of torn basil leaves. Serve as a side, or atop some fresh lettuce as a salad.
