How to Make Air Fryer Sweet Potatoes Fries
- Prepare the air fryer: Preheat the air fryer to 200°C for 3 minutes so the fries start crisping as soon as they go in.
- Prepare the potatoes: Peel the sweet potatoes if preferred, then cut into even fry-sized strips. Keeping them similar in size helps them cook evenly.
- Dry thoroughly: Pat the cut potatoes dry with kitchen paper. Removing moisture helps them brown better.
- Season the fries: Place the fries in a large bowl. Add olive oil, cornflour, paprika, garlic powder, salt, and pepper. Toss until evenly coated.
- Arrange in basket: Spread the fries in a single layer in the air fryer basket. Cook in batches if needed.
- Cook until crisp: Air fry for 18 to 20 minutes, shaking the basket halfway through cooking for even colour.
- Serve immediately: Transfer to a serving plate and enjoy while hot and crisp.

Tips
Why are my sweet potato fries soft?
Sweet potatoes contain more moisture than regular potatoes. Dry them well, use cornflour, and avoid overcrowding the basket.
How do I make them crispier?
Cook in a single layer and add a little extra cooking time if needed. Shaking halfway through also helps.
Should I soak sweet potato fries first?
It is not essential, but soaking for 30 minutes then drying well can improve texture slightly.
Can I make them spicy?
Yes, add chilli powder or cayenne pepper to the seasoning mix.
Serving Suggestions
- Serve with grilled chicken or burgers
- Pair with sandwiches or wraps
- Enjoy as a snack with dipping sauces
- Top with parmesan and herbs
