It doesn’t matter how they cook – sweet potatoes are delicious! The vegetable is versatile and pairs easily with main dishes for any meal, breakfast, lunch, or dinner. Continue reading to learn how to cook sweet potatoes in the air fryer in three ways.

How Can I Season Sweet Potatoes?

Because of their natural sweetness, a little seasoning goes a long way. For that reason, I usually season ours with kosher salt. Cumin, garam masala, Tajin, Slap Ya Mama Seasoning, onion powder, chili powder, and yellow curry powder are great options to flavor the potatoes. You can go the sweeter route with brown sugar, honey, cinnamon, pumpkin spice, or maple syrup.

Are Sweet Potatoes Healthy?

Sweet potatoes are one of the healthiest vegetables you can eat! Unlike other varieties, sweet potatoes have more soluble fiber! The bright orange interior of the sweet potatoes comes from beta-carotene, a powerful antioxidant; they are also rich in vitamins A and C.

Expert Tips

  • Select firm and even-colored potatoes free of wrinkles and blemishes.
  • Store uncooked sweet potatoes in a cool, dry place for 3-5 weeks.
  • Cut the potatoes evenly so they cook at the same rate.
  • Don’t overcrowd the basket, and cook in batches when necessary.
  • I use the Instant Pot Vortex Air Fryer, and it reminds me to move the potatoes, which I think is a helpful feature. If yours doesn’t do this, remember to shake the basket halfway through.

What to Serve with Sweet Potatoes

What to do With the Leftovers

  • Refrigerate: Store leftovers in an airtight container; they will keep for 3-4 days.
  • Freeze: Let the potatoes cool. Wrap them in foil and place them into freezer-safe containers or bags. Air fryer sweet potatoes will freeze for up to 4-6 months.
  • Reheat: Warm the leftovers in the microwave, air fryer, or oven.

Frequently Asked Questions

What kind of oil is best for sweet potatoes in the air fryer?

Use whatever oil you prefer. I recommend using one with a high smoke point for the roasted potatoes and french fries, like avocado oil.

What is the difference between yams and sweet potatoes?

Yams have a rough, brown exterior similar to yucca or russet potatoes, and the flesh is white. Yams have a neutral taste, which makes them perfect for adding to baked goods or preparing dishes like candied yams.

Sweet potatoes come in different varieties, orange, white, and purple. Orange is the type we are used to seeing in popular recipes like sweet potato casserole. In terms of flavor, sweet potatoes live up to their name.

Are sweet potatoes healthier than other potatoes?

Both are a healthy part of a well balanced diet! They are the same in terms of protein but have a few differences. Sweet potatoes contain more fiber and are rich in vitamins, particularly A and C. If you’re looking for more folate or potassium, reach for a regular russet potato.
