Wash and pat dry 2 Sweet potatoes. Prick all over with a fork.
Rub 2 teaspoon Olive oil all over the potatoes and season with 2 pinch Sea salt and 2 pinch Ground black pepper.
Put into the preheated air fryer and cook for 30 minutes.
Let the potatoes cool for a few minutes so they can be handled. Slice open and fluff up the insides with a fork. Add your toppings as desired.
Notes
Choose sweet potatoes that are similar in size for even cooking.
To check if the air fryer sweet potatoes are done, insert a fork or skewer into the centre. It should slide in easily.
Remove the sweet potatoes from the air fryer and let them cool for a few minutes. Slice them open and fluff the insides with a fork before serving.
If you're in a hurry, you can start the sweet potatoes in the microwave. Pierce and microwave on high for 5-6 minutes before transferring to the air fryer to finish cooking and crisp up the skin.
If you have a small air fryer, you might need to cook the sweet potatoes in batches to avoid overcrowding.
To ensure even cooking of the air fryer baked sweet potato, flip the sweet potatoes halfway through the cooking time. Use tongs to handle them safely.
For an even crispier skin, after the initial cooking time, brush the sweet potatoes with a bit more olive oil and cook for an additional 5 minutes.
Don't forget to pierce holes in the sweet potatoes, otherwise they will burst in the air fryer.
