The sweet potato is a vegetable with a sweet flavor and a very pleasant texture. In cooking, it's often used as a good alternative to the potato; in fact, it's also known as the sweet potato.
Like the potato, it can be prepared fried or roasted, and can also be served whole or cut into sticks or chips. Sweet potatoes are excellent as a side dish, but they can also be the base of many recipes and make a wonderful appetizer.
If we want to roast whole sweet potatoes in the air fryer, we simply need to wash them well to remove any dirt, pierce them with a fork or knife, drizzle them with a little oil, and season them with salt and pepper before putting them in the air fryer . Then, we program it for 30 minutes at 200ºC, and they'll be ready.
Cooking vegetables like sweet potatoes in an air fryer is a great option in terms of saving energy and oil consumption when used as an alternative to traditional frying ; however, when we want to achieve a "fried" finish, certain guidelines must be followed:
- It's necessary to soak the sweet potato for at least half an hour, once cut into sticks, to remove some of the starch. This will make it crispier and the recipe less complicated.
- Another trick to achieve that crispy finish is to mix it with a little cornstarch.
- When cooking sweet potatoes in an air fryer , we must place them in the basket so that they are not too crowded, otherwise the air will not circulate properly between the sticks and their surface will not dry, so they will cook, but they will be softer.
- It is necessary to cook it at a high temperature , about 200ºC, to achieve that surface toasting and it is also advisable not to add the salt until the end, as the salt encourages the sweet potato to release moisture, the number one enemy of the crispy result.
We can season our sweet potatoes with our favorite spices and herbs. In this case, we'll simply use oil and salt, although they're also delicious with paprika, cumin, herbes de Provence… we can experiment until we find our favorite combination.

How to cook sweet potatoes in an air fryer
First, peel one large sweet potato and cut it into sticks about 5 mm wide using a knife. The thinner the sticks, the crispier they will be.
We soak the sweet potato sticks in cold water for at least 30 minutes. Then we rinse them, drain them well, and dry them with a clean cotton cloth.
Place the dried sweet potato sticks in a large bowl and add 2 tablespoons of cornstarch. Mix well until all the cornstarch is coated in the sweet potato.
Add 2 tablespoons of extra virgin olive oil and stir well until all the sweet potato is coated with the oil.
Place the sweet potato fries in the air fryer basket and set the air fryer to 200°C for 20 minutes. Every 5 minutes, stir the fries to ensure even cooking.
After this time, check if the sweet potato fries are nicely browned to your liking. If you want extra browning, program a few more minutes at the same temperature. Then, add salt to taste and serve immediately.
