Absolutely, you’re not limited to just olive oil when making sweet potato fries. In fact, several other oils can work wonderfully in the air fryer, each bringing its own unique flavor and benefits. For example, avocado oil is a fantastic option; it has a high smoke point, which makes it great for high-temperature cooking. Its subtle taste complements the natural sweetness of the potatoes without overwhelming it. Plus, it’s packed with healthy fats!
Another great alternative is grapeseed oil. This oil is not only versatile but also boasts a high smoke point, making it ideal for creating that perfectly crispy texture on your fries. Canola oil is another popular choice, especially if you’re looking for something that’s a bit more neutral in flavor. No matter which oil you choose, just keep in mind that the higher the smoke point, the better it will perform in the air fryer, ensuring that your sweet potato fries come out just right every time. Enjoy experimenting with different oils to discover what you like best!
