Top tips:
- For this recipe I do not preheat my air fryer. If you do preheat yours decrease the cook time by a few minutes.
- Depending on the size of your air fryer, and the size of the bag of sweet potato fries that you buy, you may have to air fry the fries in batches.
- For the crispiest sweet potato fries leave some space around the fries so the hot air can circulate around the fries and cook them perfectly.
- If your sweet potato fries are pre-seasoned, don't worry about adding any seasonings. If they are not pre-seasoned, season them however you prefer once they have finished cooking.
- Serving ideas: you can serve sweet potato fries plain or with your favourite dipping sauce such as ketchup, honey mustard dipping sauce, spicy mayo, or sugar free bbq sauce.
