The size matters too; medium-sized sweet potatoes are ideal since they’re easier to cut into uniform fries, which helps them cook at the same rate in your Ninja Air Fryer.

Make sure the color of the sweet potatoes reflects their variety, ranging from deep orange to purple, as this can influence the sweetness and texture of your fries. Freshness is also crucial; fresher sweet potatoes tend to have a better flavor and texture when cooked.

By picking the right kind of sweet potatoes, you set yourself up for a successful batch of homemade seasoned sweet potato fries that are both tasty and healthy.

Properly preparing the sweet potatoes

To prepare the sweet potatoes, start by washing and scrubbing them to remove any dirt or debris. Then, peel the sweet potatoes and slice them into uniform size pieces, ensuring even cooking in the air fryer.

Toss the sliced sweet potatoes with a small amount of oil and your preferred seasonings until they are evenly coated. This will help in achieving crispiness and flavor during air frying.

For added crunch, you can also lightly dust the sweet potato slices with cornstarch before placing them in the air fryer basket.

Using the right seasonings

To complement the natural sweetness of sweet potatoes, it is vital to incorporate the right seasonings. The flavors can be enhanced with a combination of garlic powder, paprika, and a pinch of cayenne pepper for a hint of heat.

Alternatively, a mix of cinnamon and nutmeg can bring out their natural sweetness while adding warmth and depth to the flavor profile. Experiment with sea salt or seasoned salt to add a savory undertone that balances the overall taste.

When seasoning sweet potato fries for air frying, always remember to toss them thoroughly in oil before sprinkling on the spices. This ensures even distribution of flavor and helps achieve that perfect seasoning-to-fry ratio for an irresistibly delicious result.

Adding cornstarch for extra crispness

When looking to achieve extra crispness in your sweet potato fries, consider adding a light coating of cornstarch to the sliced potatoes. The cornstarch helps absorb moisture from the surface of the sweet potatoes, resulting in a crisper texture when air fried.

It also aids in creating a delicate golden crust on the outside while keeping the inside soft and fluffy. Additionally, using cornstarch allows for minimal oil usage, making your sweet potato fries healthier without compromising on taste or texture.

By incorporating this simple step into your recipe, you can elevate the crunch factor of your air fryer sweet potato fries and create a delightful contrast between the crispy exterior and tender interior.
