Seasoning and toppings
For a simple seasoning, start by poking holes in the sweet potatoes with a fork and then coating them with olive oil, avocado oil, or cooking spray. You can also use a brush to apply the oil. Sprinkle the potatoes with salt and pepper, or other seasonings like curry powder, turmeric, cumin, or garam masala. If you want to add a touch of sweetness, include brown sugar or maple syrup. Place the seasoned potatoes in the air fryer basket, leaving some space between them, and air fry at the desired temperature and time.
For a more complex flavour profile, you can try a combination of black beans, onions, garlic, bell peppers, salsa, garlic powder, onion powder, cumin, sea salt, and black pepper. This mixture can be added on top of the baked sweet potato for a hearty and flavourful dish.
Another option is to stuff the sweet potatoes with different fillings. Some ideas include chicken enchilada, a vegetarian option with various vegetables, or Italian-inspired fillings. You can also sprinkle chilli powder, cinnamon, or pumpkin spice on top for a quick and easy seasoning.
Finally, a pat of butter or vegan butter is a simple and classic topping for baked sweet potatoes. Coconut oil can be used as a dairy-free alternative. These toppings can be added after slicing the potato open and fluffing the inside with a fork.
