Many people know air fryers for making crispy fries, but they are just as amazing for baking whole sweet potatoes. The secret? Convection heat. It circulates air around the potatoes, caramelizing their natural sugars and giving you a sweet, tender center with slightly crispy edges.

I drew inspiration from my classic air fryer baked potato method but made some tweaks to make sure it works perfectly with sweet potatoes. The recipe is simple, requires minimal prep, and lets the natural flavors shine. A little salt, a touch of oil, and you’re good to go.

These baked sweet potatoes are versatile. They work as a side dish for dinner, a component in meal prep (cold sweet potatoes are great in lunch bowls), or even mashed for use in desserts like sweet potato brownies or cakes.

Key Ingredients

Here’s a quick breakdown of what you’ll need and why:

Sweet Potatoes – Choose ones with smooth, firm skin and minimal wrinkles. Orange garnets, Japanese sweet potatoes, or Beauregard varieties all work beautifully.

Olive Oil or Avocado Oil – A thin layer of oil helps crisp the skin without making it greasy. You can also top with butter after baking if you like.

Salt and Pepper – Keep it simple! Salt enhances the natural sweetness, and pepper is optional if you prefer a slight kick.

Optional Toppings – Sweet toppings like cinnamon, maple syrup, or butter are delicious, while savory options like sour cream, cheese, black beans, or chives make a hearty side. You can also go creative with pecans, mini marshmallows, or brown sugar.

How to Bake Sweet Potatoes in the Air Fryer

Here’s a simple step-by-step guide:

Step 1 – Prep the Potatoes

Start by washing and scrubbing your sweet potatoes. Use a fork to poke several holes in each potato to allow steam to escape. Rub them lightly with olive oil, then sprinkle with salt (and pepper, if desired).

Step 2 – Air Fry

Place the potatoes in your air fryer basket in a single layer. Set the temperature to 400°F (200°C) and cook for 28-30 minutes. Check doneness with a fork by inserting it into the thickest part. If it slides in easily, the potatoes are ready. If not, continue cooking in 3-minute increments until tender.

Step 3 – Serve

Once baked, let the potatoes rest for a few minutes. Slice them open, add your favorite toppings, and enjoy warm.

Sweet Potato Size and Cooking Time

Cooking time depends on the size of your sweet potatoes:

• 3-4 ounces: About 27-30 minutes
• 4-5 ounces: 30-35 minutes
• 5-6 ounces: 35-40 minutes
• 6-10 ounces: 40-55 minutes

These times are based on tests with Cosori, Ninja, and Philips XL air fryers. Adjust slightly if your air fryer runs hotter or cooler.

5 Tips for Perfect Air Fryer Sweet Potatoes

Even though this recipe is simple, these tricks will ensure perfect results every time:

1. Shake the Basket – Move the potatoes around a couple of times during cooking for even crisping.
2. Don’t Overcrowd – Cook in batches if needed; air needs space to circulate.
3. Poke Holes – This prevents bursting and keeps the skin intact.
4. Know When It’s Done – Fork-tender potatoes with wrinkled skin and small caramelized sugar beads are perfect.
5. Skip Foil – Wrapping in foil will make the skin soft and soggy in an air fryer.
