I’ve explained my love for the air fryer in many recipe posts before. I mean, having a tiny oven that sits on your counter that cooks food is kind of amazing.

Anything an oven can do, an air fryer can do better. You can air fry anything that you would normally bake in the oven so much quicker! Seriously. Air fryers are the best, and I love using my Ninja Foodi and Ninja Foodi Grill to whip up food in no time

These air fryer sweet potatoes are smooth and creamy on the inside with a perfectly toasted skin. They make a simple healthy side dish, especially on busy weeknights.

💗 Why You’ll Love This Recipe

  • Only 2-3 basic ingredients!
  • Makes perfectly “baked” sweet potato every time! The skin stays crispy while the inside is soft and tender. 
  • Very little clean up! All you’ll have to clean is the air fryer basket. HOWEVER, if you add a layer of foil on the bottom of the basket and place the sweet potatoes on top, you don’t need to clean anything at all!
  • Save on electricity: Using the oven makes the entire house hot and uses a lot of electricity. The air fryer does not!
  • Quick and easy gluten-free, paleo and Whole30 compliant side dish.

🍠 Ingredients You’ll Need

  • Sweet Potatoes (medium) – Use sweet potatoes that are similar in size and shape so they cook at the same rate.
  • Avocado Oil – Coating the skins with avocado helps soften them and lightly crisp in the air fryer.
  • Flaky Sea Salt – enhances flavor.

📖 How To Make Ninja Air Fryer Baked Sweet Potato

1️⃣ Prep. Scrub 2-3 medium sized sweet potatoes clean. Using a fork or sharp knife, poke holes all around the surface of the sweet potato. Pat dry with a paper towel and then rub potatoes with light coating of  avocado oil

2️⃣ Cook. Place sweet potatoes in air fryer basket and cook for 35-40 at 400 degrees. Once potatoes are soft and cooked through, carefully remove them with tongs, sprinkle with sea salt and serve hot.

📝 Recipe Tips

Use similar size sweet potatoes that are oblong and thin. This will ensure that they cook evenly. 

Be sure to scrub the sweet potatoes well (they literally have dirt on them otherwise).

And poke plenty of holes on the surface so the steam can release from the potatoes.

Season the sweet potato skins before cooking. Sprinkle skins with cajun seasoning, Greek seasoning or your favorite spice blend.

Do not overcrowd the air fryer basket. I can fit three whole sweet potatoes in my fryer basket. Depending on the size your air fryer, you may need to work in batches.

📖How To Make Air Fryer Sweet Potato Fries

If you’d rather have fries or perhaps you just have a funky shaped sweet potato, you can cut it into fries or wedges and cook them perfectly in the air fryer.

1️⃣ With a sharp knife, cut skin-on sweet potato into evenly sized fries or wedges. Toss with avocado oil, salt and pepper.

2️⃣ Place sweet potato fries in an even layer in air fryer basket (do not overcrowd). Bake at 400 degrees for 20 minutes (using tongs to flip halfway through). Serve hot.
