How to cut sweet potatoes for an air fryer
When preparing sweet potatoes for an air fryer, it is important to cut them into evenly sized pieces. This ensures that they cook evenly and at the same rate. For sweet potato wedges, first, slice the sweet potato in half lengthwise. Then, place the cut side down on your cutting board and carefully slice at an angle to create wedges. These can be as thin or thick as you like, but remember that the air fry time will vary depending on the thickness. For sweet potato cubes, cut the sweet potatoes into rounds, and then cut these into equal-sized cubes.
Before cooking, poke several holes in the sweet potatoes with a fork to allow steam to escape and prevent the potatoes from bursting. You should also pat the sweet potatoes dry before seasoning or adding oil.

How long to cook sweet potatoes in an air fryer
The cooking time for sweet potatoes in an air fryer varies depending on the size of the potatoes and the style in which they are cut. A medium-sized whole sweet potato will take 40-45 minutes to cook at 375°F (190°C). Smaller potatoes may take less time, and larger potatoes may take longer, so it is recommended to keep an eye on them as they cook.
To cook sweet potato wedges, preheat the air fryer to 375°F (190°C) for 5 minutes. Cut the sweet potatoes into wedges, then season them with oil, salt, nutritional yeast, garlic powder, smoked paprika, and pepper.

To cook sweet potato cubes, cut the sweet potatoes into evenly sized cubes, then toss them in a bowl with olive oil, harissa, garlic powder, salt, and pepper. Preheat the air fryer according to the manufacturer's instructions, then arrange the cubes in a single layer in the air fryer. Air fry at 400°F (200°C) for 10 minutes, shaking the basket once during cooking.

A simple yet classic combination. After cooking the sweet potatoes, slice them open and season them generously with salt and pepper. You can also add a drizzle of olive oil for some extra flavor and moisture.
Cinnamon
Cinnamon is a great option if you're looking for a sweet and spicy flavor. It pairs especially well with sweet potatoes that will be used in oatmeal or other breakfast dishes.
Berbere Spice, Cumin, Coriander, and Curry Powder
These spices will give your sweet potatoes a warm and earthy flavor. You can find these spices in most grocery stores or online.
Butter and Coconut Oil
For a creamy and rich flavor, top your cooked sweet potatoes with a pat of butter or a drizzle of coconut oil. This is a great option for those who are dairy-free.

How to reheat sweet potatoes in an air fryer
Reheating sweet potatoes in an air fryer is a simple and efficient way to bring out their sweet flavour. It is also much faster than using an oven or microwave.
First, if you are reheating cooked sweet potatoes, store them in an airtight container or zip-top plastic bag in the refrigerator for up to three days. If you are cooking the sweet potatoes for the first time, wash and dry them before cooking to ensure the oil and seasoning stick to the skin.
When you are ready to reheat the sweet potatoes, preheat your air fryer to 350-400°F. Cut the sweet potatoes into halves, wedges, chunks, or 1-inch cubes. If you are cooking wedges or fries, toss them in a little oil to coat. Place the sweet potatoes in the air fryer basket in a single layer and cook for 4-12 minutes, tossing halfway, until heated through.
If you are cooking whole sweet potatoes, you can rub oil over the outside of the skin and add seasoning before wrapping the potato tightly in aluminium foil. Place the wrapped sweet potato in the air fryer basket and cook for 10-12 minutes at 350°F. Flip the potato halfway through the cooking process and continue cooking until heated all the way through.
