• 2 mediumsweet potatoes
• 15 ml (1 tablespoon)avocado oil or another neutral high-heat oil
• 1 teaspoongarlic powder
• 1 teaspoonsmoked paprika
• ½ teaspoon, or to tastekosher salt
• ¼ teaspoon, or to tasteblack pepper

Instructions

1. 1

   Cut the potatoes

   Peel the sweet potatoes and place them on a chopping board. Cut them into even pieces about 6 mm (¼ inch) thick, then dry them well to remove excess moisture.

2. 2

   Season the fries

   Mix the oil with the garlic powder, smoked paprika, salt and pepper. Add the sweet potato pieces and toss in a large bowl until coated.

3. 3

   Air fry

   Arrange the fries in a single layer in the air fryer basket, leaving a little space between them. Cook at 199°C (390°F) for 13–15 minutes, turning them about halfway through, until crisp and tender. Serve straight away, as they soften as they cool.

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 outside and soft within. This air-fryer version uses a modest amount of oil and a simple savoury spice mix.

Even cuts and a dry surface help the fries cook more evenly, while leaving room around them lets hot air circulate rather than trapping steam.

Nutrition and macros by portion

The nutrition label shows one serving as written: 132 calories, 2g protein, 24g carbs, 4g fat.

Sweet potatoes provide most of the carbohydrates, while the avocado oil contributes most of the fat; the fries themselves are modest in protein. Pair a serving with a protein-rich main and vegetables for a more balanced plate.

Choosing and cutting the potatoes

Even pieces: Aim for roughly 6 mm (¼ inch) thickness throughout. Pieces of similar size are more likely to finish at the same time.

Dry surface: Pat the cut potatoes thoroughly before seasoning. Excess moisture can make it harder for their surfaces to brown.

Getting the seasoning to stick

Oil first: Toss the fries until they have a light, even coating. This helps the powdered seasonings cling and encourages browning.

Spice balance: Garlic powder and smoked paprika bring savoury depth without adding a wet coating that could interfere with crisping.

Air-frying without soggy fries

Leave space: Spread the pieces out in a single layer with a little gap between them. If the basket is crowded, cook in batches rather than stacking the fries.

Turn halfway: Flip the fries around the middle of the 13–15 minute cooking time so they brown more evenly.

Checking for doneness

Look for lightly crisp, browned edges and a tender centre. If the fries need more time, continue cooking briefly and check again rather than relying on colour alone.

Serve promptly after cooking. The fries soften as they cool, so they are at their best straight from the air fryer.

What to serve with them

Pair the fries with a burger, sandwich or grilled main for a straightforward meal. A yoghurt-based dip or a simple salad can round out the plate.

For a more filling plate, add a protein-rich accompaniment such as beans, eggs or chicken.

Recipe notes & tips

• Cut the potatoes to a consistent thickness so they cook at a similar rate.
• Dry the cut pieces well before adding the oil and spices.
• Leave a little space between the fries in the air fryer basket.
• Turn the fries about halfway through cooking.
• Serve them as soon as they are cooked for the best texture.

Variations

• Add cayenne: Mix a pinch into the seasoning for gentle heat.
• Use cumin: Add a little ground cumin for an earthy note.
• Try dried herbs: Toss in a pinch of dried thyme or rosemary with the spices.
• Change the dip: Serve with a simple yoghurt dip or ketchup.
• Adjust the salt: Season lightly before cooking and add more at the table if needed.

Common mistakes to avoid

• Uneven cuts: Pieces cook at different speeds; aim for a consistent 6 mm (¼ inch) thickness.
• Wet potatoes: Moisture can hinder browning; dry the cut fries thoroughly.
• Crowded basket: Fries can steam and turn soggy; cook in batches if needed.
• Skipping the turn: One side may brown more than the other; flip the fries about halfway through.
• Waiting to serve: The fries soften as they cool; bring them to the table straight away.

How to store

Store cooled leftovers in an airtight container in the fridge for up to 3 days. Reheat in the air fryer until hot and crisp; they may be softer than freshly cooked fries.
