Air Fryer Sweet Potato Cubes

These easy Air Fryer Sweet Potato Cubes are the perfect balance of salty and sweet. They are tossed in olive oil, spices, and herbs and roasted until crispy and brown. Served with a tangy garlic aioli, these are the simplest and most flavorful side dish.

Ingredients:

  • 1 large sweet potato (1 pound), peeled & cut in ½ inch cubes*
  • 1 Tablespoon olive oil*
  • 1 teaspoon salt
  • 1 teaspoon chopped fresh rosemary
  • ½ teaspoon smoked paprika
  • ½ teaspoon granulated garlic
  • ¼ teaspoon pepper

Garlic Lemon Aioli

  • ¼ cup mayonnaise
  • 1 clove garlic, pressed
  • 2 teaspoons lemon juice
  • ½ teaspoon lemon zest
  • teaspoon salt
  • cracked pepper

Instructions:

  • Review all recipe notes and instructions before beginning.
  • In a small bowl, combine the mayonnaise, garlic, lemon juice, zest, salt, and pepper. Cover and place in the refrigerator.
  • In a large bowl, combine the potato cubes, olive oil, salt, rosemary, paprika, garlic, and pepper.
  • Fill the air fryer basket with sweet potato cubes (All of them will probably not fit so I recommend cooking in batches.)
  • Air fry at 390 degrees for 11-13 minutes, shaking the basket halfway through.
  • Serve the potatoes with the chilled aioli.

Notes:

Sweet Potato: There are different varieties of sweet potatoes found at the grocery store. I prefer to use Garnet sweet potatoes. They have a deep red orange skin and are orange on the inside. 
Olive Oil: Swap for avocado oil.
Refrigerator: Store leftover roasted sweet potatoes and lemon garlic aioli in airtight containers in the fridge for up to 4 days. 
Freezer: Allow the sweet potato chunks to cool completely in the fridge for 6 hours or overnight. Place the cooled sweet potatoes on a baking sheet lined with parchment paper. Freeze for 4-6 hours. Transfer the frozen potatoes to a freezer bag or airtight container.
Cut the potatoes evenly. Uniform potato chunks cook more evenly. This is why I love to use a chopper.
