After 8 minutes of cooking, open the air fryer to shake the cubes around. Cooking time will vary between 10 to 14 minutes, depending on the size of your potato cubes. They are done when the thickest sweet potato cube is soft.

Store sweet potato leftovers in an airtight container in the fridge for up to 4 days. To reheat, place them in the air fryer again at 350F for about 3-4 minutes until they are heated through.

These sweet potato cubes make a nutritious side for pan-seared chicken breasts, healthy turkey burgers, or Spanish salmon. I also love add them as a topping for my delicious winter salad or even as a swap of butternut squash in these roasted chickpea tacos.
