HOW CAN I SEASON 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?

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.
