Air Fryer Recipe
Harissa Sweet Potato Chips
Harissa Sweet Potato Chips are a spicy and aromatic snack made healthier by air frying, offering a delightful combination of sweet and salty flavors.
Ingredients
- 2 large sweet potatoes
- 2 tablespoons olive oil
- 1 tablespoon harissa paste
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika
- Salt to taste
Method
- Peel the sweet potatoes and slice them thinly, aiming for a consistent thickness.
- In a large bowl, mix olive oil, harissa paste, garlic powder, and smoked paprika.
- Add sweet potato slices to the bowl and toss until well coated.
- Preheat air fryer to 180°C (356°F) for about 5 minutes.
- Arrange seasoned potato slices in a single layer in the air fryer's basket.
- Cook for 10-15 minutes, flipping halfway through.
- Check for crispness and adjust cooking time if necessary.
- Season with salt while warm.
Why this works in an air fryer
Thin, even sweet potato slices crisp because hot air can drive off surface moisture before the sugars scorch. A light oil-harissa coating improves heat transfer and carries paprika flavour, while preheating gives immediate convection so the outside dehydrates rather than steams.
Equipment notes
Assumes a 4–5 litre basket holding one large sweet potato in a true single layer; cook in batches if needed. In a single-drawer fryer, place slices around the hotter outer edge and shake/flip well; in dual-zone models, split evenly between drawers and check 2–3 minutes early as smaller loads brown faster.
Common pitfalls
- Edges black but centres bendy by minute 10? The slices are too thick or uneven; remove the dark ones, cut the rest thinner next time, and finish at 160°C for a few extra minutes.
- Slices look wet and orange rather than blistered halfway through? The basket is overcrowded and trapping steam; cook in a single layer in batches and pat the coated slices lightly before frying.
- Harissa coating tastes bitter or has dark specks before the chips crisp? The paste is catching; drop to 170°C and toss with a little extra oil to dilute the chilli solids.
- Chips go soft within minutes of serving? They were salted too early or piled up; salt only after cooking and spread on a rack or plate rather than a bowl.
Variations & substitutions
- Use rose harissa for a more floral heat; its higher sugar content can brown quicker, so start checking 2 minutes earlier.
- Swap olive oil for rapeseed oil for a more neutral flavour and slightly cleaner high-heat browning.
- Use chipotle paste instead of harissa for smoky heat; it is often thicker, so loosen it with an extra teaspoon of oil for even coating.
- Leave the skins on for more chew and earthy flavour; scrub well and expect the edges to crisp before the centres.
Storage & reheating
Keep cooled chips in an airtight container in the fridge for up to 3 days, then reheat in the air fryer at 180°C for 3–5 minutes in a single layer to restore crispness.
