1. Soak the potatoes in cold water for 45 mins to remove the starch. When you have 5 mins left, insert the Ninja Air Fryer’s crisper plate into the pan, then place the pan into the air fryer. Select AIR FRY, set the temperature to 150°C and the time to 43 mins. Press START/STOP to begin and allow to preheat for 3 mins.
2. Dry half of the sweet potato wedges with a clean tea towel. Place in a large mixing bowl with 1 tbsp vegetable oil and half the paprika. Stir to coat every wedge evenly.
3. Once the air fryer is preheated, place the wedges onto the crisper plate and cook for 5 mins, then remove the pan and shake them, or toss them with silicone-tipped tongs. Reinsert the pan and resume cooking.
4. After 20 mins, transfer the cooked wedges to a bowl and repeat the previous steps with the remaining half of sweet potato wedges. Once all the wedges have had 20 mins of cooking time, add to a large mixing bowl with 1 tbsp vegetable oil, and all the thyme, salt and cumin. Select AIR FRY, set the temperature to 200°C, and the time to 20 mins. Press START/STOP to begin and allow to preheat for 3 mins.
5. Once preheated, place all the wedges in the pan and resume cooking. Remove and shake after 5 mins, then return to the pan. Once cooked, garnish with the parsley and serve immediately.
