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 salt. Cumin, North Indian garam masala, Tajin, onion powder, chili powder, and yellow curry powder are great options to flavor sweet potatoes. You can also take the sweetness to the next level with brown sugar, honey, cinnamon, pumpkin spice, or maple.

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.

COOKING TIPS

  • At the store, choose firm even-colored potatoes free of wrinkles and cracks.
  • 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; 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 flip the sweet potatoes halfway through.

FREQUENTLY ASKED QUESTIONS

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

Use whatever oil you prefer; I recommend 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 of them are healthy! 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.
