Ingredients

2 medium sweet potatoes, peeled and cut into thin fries
1 tablespoon olive oil
1 teaspoon sea salt
½ teaspoon garlic powder
½ teaspoon smoked paprika
Freshly ground black pepper, to taste
Optional: chopped fresh rosemary or thyme

Directions

Prepare the sweet potatoes
Wash and dry the sweet potatoes thoroughly. Peel them if you prefer, or leave the skin on after washing well.
Cut them into evenly sized fries so they cook at a similar rate. Thinner fries generally cook faster, while thicker pieces take longer to soften in the center.
Season the fries
Place the cut sweet potatoes in a bowl and toss them with olive oil, salt, and any optional seasonings you enjoy. Coat them lightly rather than adding too much oil.
For the best results, make sure the seasoning is distributed evenly over the fries.
Preheat the air fryer
Preheat your air fryer according to the manufacturer’s instructions, if preheating is recommended for your model.
Arrange the fries in a single layer in the basket as much as possible. If you’re preparing a large batch, cook in several batches rather than overcrowding the basket.
Air fry until golden
Air fry at approximately 190°C (375°F) for 12–18 minutes, shaking the basket halfway through cooking.
The exact cooking time depends on the thickness of the fries, the quantity in the basket, and your air fryer model. Check them towards the end of cooking and continue in short intervals if necessary.
The fries are ready when they are tender inside and lightly browned around the edges.
Serve immediately
Carefully remove the fries from the basket and serve while hot. Add extra seasoning to taste and pair with your favorite dipping sauce.

Notes

Cut the sweet potatoes into evenly sized fries.
Dry them well before seasoning.
Arrange them in a single layer where possible.
Shake the basket halfway through cooking.
Cooking times vary by air fryer model and fry thickness.
Serve immediately for the best texture.

Cut the fries evenly. Similar-sized pieces help prevent some fries from becoming too dark while others remain undercooked.

Dry the sweet potatoes well. Removing excess moisture before seasoning helps the surface cook more effectively.

Avoid overcrowding the basket. Air needs to circulate around the fries. Too many pieces at once can lead to softer results and uneven browning.

Shake the basket during cooking. Turning the fries helps expose different sides to the circulating hot air.

Check early if your fries are thin. Smaller pieces may cook faster than expected, so start checking before the end of the suggested cooking time.

Remember that sweet potatoes behave differently from regular potatoes. Their natural sugars can cause the edges to brown quickly. If the fries are darkening before the centers are tender, reduce the temperature slightly and continue cooking.

Frequently Asked Questions

Do I need to peel sweet potatoes before air frying?

No. You can leave the skin on after washing and drying the sweet potatoes thoroughly. Peel them if you prefer a smoother texture.

Why are my sweet potato fries soft?

Overcrowding, excess moisture, and thick or uneven cuts can prevent the fries from browning evenly. Cook in smaller batches and shake the basket halfway through.

Can I cook frozen sweet potato fries in the air fryer?

Yes. Follow the package instructions for temperature and cooking time, as frozen fries vary by brand and thickness. Shake the basket during cooking for more even results.

Can I make these fries without olive oil?

Yes, although a small amount of oil helps the seasoning adhere and encourages browning. The texture may be drier without it.

What temperature is best for air fryer sweet potato fries?

Around 190°C (375°F) is a useful starting point for homemade fries. Adjust the temperature and cooking time according to their thickness and your air fryer model.
