Recipe instructions
Below are the simple step-by-step instructions with images on how to make this recipe.
Wash and peel the potatoes. Wash, scrub and pat dry the potato well. Use a veggie peel or a sharp knife to peel the skin.
Note: I prefer peeled sweet potatoes, but you do not have to peel them.
Cut into cubes. Place the potato on a cutting board and slice it into ½-1 inch disks. Stack them by two and cut them into even cubes.
Season the potatoes. In a large mixing bowl, add sweet potato cubes, salt, seasonings, and olive oil. Toss them until well coated. If you have time, let them marinade for a couple of minutes, 10 minutes is plenty.
Air fry at 390°F. Arrange the potatoes in the air fryer basket in a single layer. Air fry at 390 degrees f for 12-15 minutes, shaking and tossing them halfway through or until the edges are browned and they are tender soft inside when pierced with the fork.
Expert Tips
- If you decide to keep the peel on, make sure to scrub and pat dry the potatoes well.
- It is better to cut the potatoes into smaller ½-1 inch cubes. Larger cubes will take longer to cook and will not crisp up that well.
- Cook them in batches to avoid overcrowding the air fryer basket.
- Cooking times may be different depending on your air fryer model and the size of the cubes.
How to store and reheat
Transfer the leftovers to an airtight container and store them in the fridge for 3-4 days. Air frying them for about 3-4 minutes is the best way to reheat.
It is safe to freeze roasted sweet potatoes for up to 3 months. I do not recommend freezing roasted potatoes as their texture might be different after reheating.
If you freeze the potatoes, use the air fryer to reheat them for the best results.
