Parmesan & Rosemary Air Fryer Sweet Potatoes: Easy & Flavorful

Sweet potatoes have become a beloved staple in many households, praised not only for their delightful sweetness and versatility but also for their nutritional benefits. Cooking them in an air fryer takes these nutrient-packed gems to a whole new level, producing a crispy exterior while maintaining a soft and tender interior. In this article, we’ll explore how to create delicious Parmesan & Rosemary Air Fryer Sweet Potatoes—a dish that’s as simple as it is flavourful.

Why Choose the Air Fryer?

The air fryer has revolutionised the way we cook, allowing for healthier versions of our favourite fried foods. By circulating hot air around the food, air fryers achieve that crispy texture without the need for excessive oil. This method is not only quicker than traditional frying but also results in lower fat content, making it an ideal choice for those looking to enjoy their favourite dishes without the guilt.

Ingredients

To whip up this delight, you will need:

  • 500g sweet potatoes, washed and peeled
  • 2 tablespoons olive oil
  • 50g grated Parmesan cheese
  • 1 tablespoon fresh rosemary, finely chopped (or 1 teaspoon dried)
  • Salt and freshly ground black pepper, to taste
  • Optional: a pinch of garlic powder for an extra layer of flavour

Instructions

  1. Preparation: Begin by washing and peeling the sweet potatoes. Cut them into evenly sized wedges or cubes, as this ensures even cooking.

  2. Coat the Sweet Potatoes: In a large bowl, toss the sweet potato pieces with olive oil, ensuring they’re well-coated. This step is crucial as the oil helps to achieve that coveted crispy texture.

  3. Add the Flavours: Sprinkle in the grated Parmesan cheese, chopped rosemary, salt, pepper, and, if desired, garlic powder. Toss the sweet potatoes again to coat them evenly in the cheesy, herby mixture.

  4. Preheat the Air Fryer: Preheat your air fryer to 200°C (about 400°F) for approximately 5 minutes. This ensures a nice initial heat that helps to crisp the sweet potatoes from the very start.

  5. Air Frying: Place the sweet potato pieces in the air fryer basket in a single layer. Depending on your air fryer’s capacity, you may need to do this in batches. Cook for 15-20 minutes, shaking the basket halfway through to ensure even cooking. You’ll know they’re done when they are golden brown and crispy on the outside, with a soft interior.

  6. Serving Suggestions: Once cooked, remove the sweet potatoes from the air fryer and let them cool for a few minutes. You can sprinkle a little extra Parmesan on top for a cheesy finish if desired. Serve these delightful bites as a side dish, or enjoy them as a tasty snack on their own.
