Prepare the beets by washing them thoroughly under cold water. Trim off the leafy tops and roots, then peel the beets using a vegetable peeler. The peeling is optional but recommended for better texture.
Cut the beets into uniform pieces, aiming for 1-inch cubes or ½-inch thick wedges. Consistent sizing ensures even cooking throughout.
Place the cut beets in a mixing bowl and drizzle with olive oil. Sprinkle with salt, pepper, and dried herbs if using. Toss until all pieces are evenly coated.
Preheat your air fryer to 380°F (193°C) for 2-3 minutes. This ensures proper cooking temperature from the start.
Arrange the seasoned beets in a single layer in your air fryer basket. Avoid overcrowding – cook in batches if necessary for proper air circulation.
Cook for 15 minutes, then shake the basket or flip the beets with tongs. Continue cooking for another 5-10 minutes until the beets are tender when pierced with a fork and slightly crispy on the edges.
Transfer the hot beets to a serving dish and immediately drizzle with balsamic vinegar while they’re still hot. This allows the vinegar to slightly caramelize on the warm surface.
Top with goat cheese and fresh herbs if desired, allowing the cheese to slightly melt from the residual heat.
