Why Air Frying is the Best Way to Cook Sweet Potatoes
If you’ve ever microwaved a sweet potato only to end up with a dry, rubbery texture, or waited an hour for the oven to do its job, you’ll love how the air fryer transforms them. Air Fryer Baked Sweet Potatoes come out perfectly fork-tender, with caramelized skin and a fluffy interior—ready in nearly half the baking time. Plus, the peels slip right off, making them ideal for other recipes like my Sweet Potato Pie or Sweet Potato Cornbread.
Batch-cooking sweet potatoes in the air fryer is a game changer for meal prep. Whether you’re making a quick lunch, a side dish, or a base for bowls and salads, this method ensures consistent results every time. Just season with simple salt and pepper, or mix it up with your favorite spices and toppings.
Best Varieties of Sweet Potatoes for Air Frying
Not all sweet potatoes are the same! Here’s a quick guide to popular varieties of sweet potatoes and what they’re best for:
- Garnet Sweet Potatoes – Deep orange flesh with a rich, almost nutty flavor. They caramelize beautifully in the air fryer and are excellent for roasting, mashing, or baking into desserts. Peak season: Fall and winter.
- Jewel Sweet Potatoes – Similar to Garnet but slightly milder in flavor. Great for all-purpose cooking, from fries to soups. Peak season: Year-round but best in late fall.
- Japanese Sweet Potatoes – White or yellow flesh with a drier, chestnut-like texture. They crisp up well in the air fryer and are delicious with just a sprinkle of salt. Peak season: Fall through winter.
- Purple Sweet Potatoes – Earthy and slightly less sweet, these have vibrant purple flesh and are best for roasting or making striking mashed potatoes. Peak season: Fall through spring.
Whether you’re cooking one or making a batch, this air fryer method works for all varieties, bringing out their natural sweetness while keeping them light and fluffy inside.
I love my air fryer and have been regularly adding to my air fryer recipes!
Simple Ingredients for Air Fryer Whole Sweet Potato
- Sweet potatoes: Choose similar-sized sweet potatoes, wash them well, and dry them well.
- Spray Oil & Kosher Salt: I like a little spritz on mine to crisp the skins even more! But it’s not necessary.
- Optional toppings: Some like to enjoy their sweet potatoes plain. However, most want to add a little something special. Read to the end of the post where I have loads of topping ideas!
The Best Air Fryer
The best air fryer is the one that works with your budget, kitchen space and lifestyle! Here are my favorites priced from lowest to highest:

How to Air Fry Sweet Potatoes
With less than five minutes of prep time and 35 of cooking time, these air fryer sweet potatoes make a great weeknight side or work great for meal prep.
Start this simple recipe with some basic prep. Wash your sweet potatoes, dry them really well. Then, carefully pierce them with a fork to prevent them from bursting out of their skin while being cooked.
Next, spray or brush the whole sweet potatoes with avocado oil or olive oil, if desired. This will create a crispier outside once cooked. If desired, sprinkle with a little kosher salt.
Then, place the sweet potatoes in your Air Fryer basket in a single layer; the rest is almost entirely hands-free!
Do not preheat the air fryer! Simply set the air fryer to 390° F cooking for about 35 minutes. The skins will crisp better if you start it when you place the sweet potatoes in the basket.
You will know your sweet potatoes are done when they start to ooze a bit of juices from the holes made with your fork. Or do a simple squeeze test with a hot pad, if they give to gentle pressure they are done!
Carefully remove the fluffy sweet potatoes from the air fryer basket and serve with your favorite toppings—And that’s it!
Do I have to soak potatoes before air frying?
No, you don’t need to soak sweet potatoes before air frying. Unlike regular white potatoes, sweet potatoes have a different starch and sugar composition, so soaking doesn’t significantly impact their texture.
When should I soak sweet potatoes?
If you’re making sweet potato fries and want them extra crispy, a quick 30-minute soak in cold water can help remove some surface starch. However, for whole or baked sweet potatoes, soaking is unnecessary.
Fresh Tips
- The best way to wash your sweet potatoes is to scrub them with a vegetable scrubber or brush in circular motions. Run them under cool water, and remember to dry them really well before spraying with oil or adding them to the air fryer.
- Choose similar-sized whole sweet potatoes, so they bake evenly.
- Air fryer baked sweet potato is a healthy choice, great for meal prep!

How can I prevent soggy sweet potatoes?
Try these tips for crispy, fluffy air fryer sweet potatoes:
- Increase the temperature: Cooking at 375-400°F (190-200°C) usually works best for crisping up the skin while keeping the inside tender.
- Don’t overcrowd the basket: Too many potatoes at once will trap steam, making them soft instead of crispy. Cook in batches if needed.
- Pat them dry: If washing or soaking, be sure to dry them thoroughly before air frying.
- Use a little oil: A light oil coating (like avocado or olive oil) helps crisp up the skin and prevents drying out.
- Preheat the air fryer: Starting with a hot air fryer ensures even cooking and helps crisp the outside faster.
Storage Tips
Refrigerate Leftovers: Let cooked sweet potatoes cool completely, then store them in an airtight container in the fridge for up to one week. When ready to eat, simply reheat and serve.
Freezing Instructions:
Make sure they are completely cooled before storing to avoid excess moisture.
- Whole sweet potatoes: Wrap tightly in foil, then place in a freezer-safe bag and freeze for up to 6 months.
- Mashed or boiled sweet potatoes: Transfer to an airtight container or freezer-safe bag, pressing out as much air as possible before freezing.
How to Reheat Sweet Potatoes in the Air Fryer:
For the best texture, slice your sweet potato in half and place it in a preheated 350°F air fryer. Air fry for 3-5 minutes until warm and slightly crispy.
