What are sweet potato fries?

Sweet potato fries are a familiar American-style side, made by cutting sweet potatoes into sticks and cooking them until browned at the edges. This version uses an air fryer and a short list of seasonings for a straightforward alternative to deep-frying.

The sweet potatoes bring natural sweetness, while olive oil helps the outside brown and salt and pepper keep the flavour simple. The fries are best enjoyed hot, when their edges are at their crispest.

Nutrition and macros by portion

The nutrition label shows one serving as written: 139 calories, 2g protein, 23g carbs, 5g fat.

The sweet potatoes provide most of the carbohydrates, while the olive oil supplies most of the fat; the potatoes contribute a little protein. Pair a serving with a protein-rich main and vegetables to make a more balanced plate.

Choosing and cutting the potatoes

Even sticks: Cut the fries to a similar thickness, around 6 mm, so they cook at roughly the same rate. Thicker pieces may need longer, while very thin ones can brown quickly.

Clean skins: Scrub the potatoes well under running water before cutting. The recipe leaves the skins on, so there is no need to peel them.

Coating them evenly

Olive oil: Toss the sticks thoroughly in a large bowl so they have a light, even coating. This helps the seasoning cling and supports browning in the air fryer.

Seasoning: Distribute the salt and pepper across the fries rather than adding them in one spot. A small extra pinch can be added after cooking to taste.

Give the basket room

Airflow: Arrange the fries without packing the basket too tightly. If they are piled up, they are less likely to brown evenly, so cook in batches if needed.

Turning: Shake the basket or turn the fries every 7–10 minutes during the 25-minute cooking time. Check them more closely towards the end, as some may finish before others.

Check for doneness

Look for browned edges and fries that feel tender when pierced. Sweet potato pieces may not all cook at the same pace, so remove any that are already well done to keep them from burning.

The finished texture depends partly on the thickness of the cut and how much space the fries have in the basket. Let the visual and tenderness cues guide the final minutes.

Serving ideas

These fries work alongside burgers, grilled food or sandwiches, and the optional cilantro adds a fresh herbal finish. Serve them soon after cooking for the best contrast between tender centres and browned edges.

For a fuller plate, pair them with a protein-rich main and a fresh salad or other vegetables. Keep extra seasoning on the side so everyone can adjust their portion.

Recipe notes & tips

• Cut the potatoes into evenly sized sticks so they cook at a similar pace.
• Toss the fries well to distribute the oil, salt and pepper.
• Leave space around the fries in the basket, cooking in batches if necessary.
• Shake the basket or turn the fries every 7–10 minutes.
• Watch closely near the end and remove any fries that are done early.
• Serve soon after cooking for the best texture.

Variations

• Add paprika: Toss a little paprika with the fries alongside the salt and pepper.
• Try garlic: Add a small amount of garlic powder to the seasoning before cooking.
• Use fresh herbs: Finish with chopped parsley instead of cilantro.
• Add a dip: Serve with a favourite dip on the side.
• Make them spicier: Add a pinch of chilli powder with the other seasonings.

Common mistakes to avoid

• Uneven cuts: Fries of different thicknesses cook at different rates; aim for sticks around 6 mm thick.
• Crowded basket: Packed fries brown less evenly; cook them in batches if needed.
• Missed turns: Leaving the fries untouched can lead to uneven cooking; shake or turn them every 7–10 minutes.
• Late checking: Some fries may finish early; inspect them near the end and remove the well-done pieces.
• Too much seasoning at once: Salt can be adjusted after cooking; season lightly to taste before serving.

How to store

Refrigerate leftover fries in an airtight container for up to 3 days. Reheat them in the air fryer until hot, checking frequently so they do not overcook; they may be softer than when freshly made.
