Special Equipment

  • Air fryer or regular oven


  • 1 ½ pounds sweet potatoes, about 3 medium
  • 2 Tablespoons olive oil
  • 2 Tablespoons fresh squeezed lime juice
  • 1 teaspoon garlic powder
  • 1 teaspoon chili powder
  • ½ teaspoon freshly ground black pepper, ¼ teaspoon if you want less spice
  • ¼ teaspoon cayenne pepper, less if you want less spice
  • 1 to 2 teaspoons coarse sea salt
  • 2 Tablespoons finely minced fresh Italian parsley


  • Peel the sweet potatoes and slice crosswise into ¼" thick rounds. You can also make sticks, about ½" wide, if you prefer. Then place into a medium bowl.
  • Mix the oil and lime juice together either using a whisk until emulsified or, my preferred method, in a sealed jar. Place the oil and juice into a jar, seal and shake vigorously; this emulsifies the liquids quickly and thoroughly.
  • Pour the oil and juice mixture over the sweet potatoes and toss until the potatoes are well coated. I like to use my hands for this to make sure every surface is covered.
  • In a small bowl mix together the garlic powder, chili powder, black pepper and cayenne.
  • Pour these spices over the potatoes and mix throughly. Again, I use my hands. But by all means use a wooden spoon if you prefer.

To cook in your air fryer:

  • Place some of the slices into your air fryer. I lay them out so they aren't overlapping.
  • Set the temperature to 400° F and the timer for 15 minutes and cook.
  • When done, remove the slices and replace with more slices. You should be able to finish in 3 times.

To cook in your oven:

  • (Adding instructions, but these are MUCH better in the air fryer.)
  • Heat your oven to 450° F. If you have a convection oven, I recommend using that.
  • Cover a large baking pan or cookie sheet with parchment paper.
  • Lay the slices on the pan and cook for 25 to 30 minutes. Turn the potatoes over halfway through cooking. The time will depend a lot upon your individual oven. I advise checking them at 20 minutes.

Finishing the dish:

  • When the sweet potatoes are cooked, sprinkle both sides with the sea salt and parsley to your taste.
  • Serve and enjoy!
