Air Fryer Baked Sweet Potatoes

There are some side dishes I make because they’re easy.

And then there are side dishes that are so good, I find myself making them even when I don’t really need a side dish at all.

These Air Fryer Baked Sweet Potatoes are definitely in the second category.

The outside gets beautifully crisp and slightly caramelized, while the inside becomes soft, fluffy, and naturally sweet.

And because the air fryer cooks them so beautifully, you get that oven-baked texture without having to heat up the entire kitchen.

I first tried making sweet potatoes this way on a busy weekend.

I had a few sweet potatoes sitting on the counter and didn’t want to wait nearly an hour for the oven.

So I gave the air fryer a try.

I washed the potatoes, rubbed them with a little oil and salt, and put them straight into the basket.

About 35 minutes later, I opened the air fryer and found exactly what I wanted—crispy skins and soft, steaming centers.

I split one open, added butter, and took a bite.

That was it.

I was hooked.

Now these sweet potatoes show up regularly at our table, especially when I want an easy side dish that doesn’t require much attention.

They’re wonderful with butter and cinnamon, but they’re also delicious topped with savory ingredients for lunch or dinner.

How to Make Air Fryer Baked Sweet Potatoes

Step 1: Wash the Sweet Potatoes

Scrub the sweet potatoes thoroughly under cool running water.

Sweet potato skins are edible, so there’s no need to peel them.

Dry them completely with a clean kitchen towel or paper towel.

Dry skins become much crispier in the air fryer.

Step 2: Pierce the Potatoes

Use a fork to poke several holes around each sweet potato.

This allows steam to escape while they cook.

You don’t need to make dozens of holes—just a few around each potato is enough.

Step 3: Add Oil and Salt

Place the sweet potatoes in a bowl.

Rub each one lightly with olive oil.

Sprinkle with salt.

Make sure the skins are lightly coated.

Step 4: Air Fry

Preheat your air fryer to 200°C (400°F) if your model recommends preheating.

Place the sweet potatoes in the basket.

Leave a little space between them so the hot air can circulate.

Air fry for approximately 35–45 minutes, depending on the size of your potatoes.

Turn them halfway through cooking.

Step 5: Check for Doneness

Insert a fork or thin knife into the thickest part of the potato.

It should slide in very easily.

If the center is still firm, continue cooking for another 5–10 minutes.

Larger sweet potatoes may take closer to 50 minutes.

Step 6: Serve

Carefully remove the potatoes from the air fryer.

Let them cool for a couple of minutes.

Slice each potato lengthwise and gently squeeze the ends to open it.

Fluff the center with a fork.

Add your favorite toppings and serve warm.

My Best Tips

Choose Similar-Sized Potatoes

If all the sweet potatoes are approximately the same size, they’ll finish cooking around the same time.

Don’t Wrap Them in Foil

Foil traps moisture and prevents the skin from getting properly crisp.

For crispy skins, put the sweet potatoes directly into the air fryer basket.

Dry the Skins Well

Moisture is the enemy of crispy skin.

Dry them thoroughly before adding oil.

Don’t Overcrowd the Basket

Give the potatoes enough space for the hot air to circulate around them.

How Long Do Sweet Potatoes Take in the Air Fryer?

The exact time depends on their size.

As a general guide:

• Small: 30–35 minutes
• Medium: 35–45 minutes
• Large: 45–55 minutes

Always check the center with a fork rather than relying only on the clock.

Do I Need to Boil Them First?

No.

One of the best things about this recipe is that you can cook the sweet potatoes directly from raw.

The air fryer does all the work.

Can I Cook Sweet Potatoes Without Oil?

Yes.

The oil helps crisp and season the skin, but you can skip it if you prefer.

The skins won’t be quite as crisp.

Can I Use Avocado Oil?

Absolutely.

Avocado oil is an excellent choice for air frying.

You can also use olive oil or another cooking oil suitable for high-heat cooking.

What to Serve With Air Fryer Sweet Potatoes

They’re wonderful alongside:

• Grilled chicken
• Roast chicken
• Steak
• Pork chops
• Salmon
• Shrimp
• Turkey
• Burgers
• Roasted vegetables

They can also be a complete meal when loaded with protein and vegetables.

Can I Make These Ahead?

Yes.

Cooked sweet potatoes can be refrigerated and reheated when needed.

They’re excellent for meal prep because they can be used with different toppings throughout the week.

Storage

Allow cooked sweet potatoes to cool before transferring them to an airtight container.

Refrigerate for up to 3–4 days.

How to Reheat

The air fryer is the best option for bringing back the crispy skin.

Air fry at 180°C (350°F) for approximately 5–10 minutes, depending on size.

You can also microwave them, but the skin will become softer.

Can I Freeze Baked Sweet Potatoes?

Yes.

Allow them to cool completely.

Wrap individually and place in a freezer-safe container or bag.

Freeze for up to 3 months.

Thaw in the refrigerator overnight and reheat in the oven or air fryer.

Frequently Asked Questions

Do I have to peel sweet potatoes?

No. The skin is completely edible and becomes deliciously crisp in the air fryer.

Why aren’t my sweet potato skins crispy?

Make sure the potatoes are completely dry before adding oil. Also avoid overcrowding the air fryer basket.

Why are my sweet potatoes taking so long?

Large potatoes can take significantly longer than small ones. Always check the center with a fork for tenderness.

Can I cook them at 180°C instead?

Yes. They will still cook well, although they may take a little longer and the skin may not become quite as crisp.

Should I turn them halfway?

I recommend it for more even cooking, although some air fryers circulate heat well enough that it’s not strictly necessary.

Can I make these with Japanese sweet potatoes?

Absolutely. Japanese sweet potatoes have a slightly drier, starchier texture and become wonderfully fluffy when air-fried.

Final Thoughts

These Air Fryer Baked Sweet Potatoes are proof that sometimes the easiest recipes are the ones worth keeping.

There’s almost no preparation.

No complicated ingredients.

No standing over the stove.

Just sweet potatoes, a little oil, some salt, and your air fryer.

Then you get that beautiful contrast between the crisp, caramelized skin and the soft, fluffy center.

I especially love splitting one open while it’s still hot and watching the butter melt down into all those little fluffy pockets.

But don’t stop at butter.

Turn them into a full meal with bacon and cheese, make them sweet with cinnamon and maple syrup, or top them with chicken, beans, or vegetables.

They’re simple enough for a weeknight and delicious enough that you’ll probably find yourself making them again before you even realize it.

Sometimes the best recipes really are the ones that let the ingredients do most of the work. 🍠✨
