Heat your air fryer to 400 °F.

While your air fryer is heating, peel your beets and chop into ½ inch cubes.

Toss the cubed beets in 1 tablespoon of olive oil and 1 teaspoon of flaky sea salt. Combine the beets, oil, and salt with your hands so the oil and salt coat the beets evenly.

Cook in the air fryer until the beets are fork-tender on the inside and crispy on the outside, about 30-35 minutes.

About halfway through cooking the beets, check to ensure they are not too dry by adding a drizzle of olive oil to coat the beets if needed while they finish cooking.

Serve with additional flaky sea salt as desired!
