Basic Steps for Air Frying Sweet Potatoes

1. Prep the Sweet Potatoes:

  • Start by washing and peeling the sweet potatoes (if desired). You can also leave the skin on for added fiber and nutrients.
  • Cut the sweet potatoes into your preferred shape: fries, wedges, cubes, or rounds. For even cooking, try to maintain uniform sizes.

2. Season and Oil:

  • Place the sweet potato pieces in a bowl and drizzle with a small amount of oil (usually about 1-2 tablespoons per pound of sweet potatoes).
  • Season generously with salt, pepper, and your choice of spices. Paprika, garlic powder, and rosemary are popular options.

3. Preheat the Air Fryer:

  • Preheat your air fryer to around 380-400°F (190-200°C). This step ensures that your sweet potatoes cook evenly and become wonderfully crispy.

4. Arrange in the Basket:

  • Spread the seasoned sweet potato pieces in a single layer in the air fryer basket. Avoid overcrowding to allow proper air circulation.

5. Cooking Time:

  • The cooking time can vary depending on your air fryer’s size and model. Typically, it takes about 15-20 minutes. Flip or shake the basket halfway through to ensure even cooking.

6. Check for Doneness:

  • To know when your sweet potatoes are ready, look for a crispy exterior and tender interior. Use a fork to test doneness – it should easily pierce the sweet potato.

7. Serve and Enjoy:

  • Once they’re perfectly cooked, remove the sweet potatoes from the air fryer, and serve immediately. Enjoy them plain or with your favorite dipping sauce.
