Start by preheating your air fryer to 375°F (190°C).
While the air fryer is preheating, wash and peel the beets. Cut them into 1-inch cubes.
Mix the beets with olive oil, garlic powder, dried thyme, salt, and pepper in a bowl. Make sure the beets are evenly coated with the seasoning.
Place the seasoned beets in the air fryer basket in a single layer. If your air fryer is on the smaller side, you may need to cook the beets in batches.
Cook the beets for 15-20 minutes, shaking the basket halfway through to ensure even cooking.
Once the beets are crispy and tender, remove them from the air fryer and let them cool for a few minutes before serving.
