  • Air Fryer


  • 1 ½ lb potatoes
  • 1 Tablespoon Lemon pepper seasoning reserve about ½ teaspoon for the onions
  • 1 ½ cups yellow onions chopped
  • 1 teaspoon garlic granules
  • 2 Tablespoons olive oil any other flavorless oil will work for this recipe
  • Salt to taste


  • Scrub the potatoes clean under cold running water, cut them into small cubes, add to a colander and rinse with cold water. Drain and pat dry with a kitchen paper towel and transfer into a large mixing bowl.
  • Preheat the air fryer at 190/375F for 3 minutes
  • To the bowl of the potatoes, sprinkle the lemon pepper seasoning, garlic granules, and some salt, drizzle 1 ½ Tablespoons of olive oil and toss everything together until coated.
  • Transfer the potatoes into the air fryer basket or tray, making sure not to overcrowd it. Cook for 12 minutes at 190C/375F, shaking the basket halfway through the cooking time.
  • In the meantime peel and roughly chop the onions, and add it to the same bowl you used for the potatoes. Season the onions with the reserved lemon pepper, and salt, drizzle the rest of the olive oil and stir so that the onions are well coated.
  • After 12 minutes, remove the air fryer basket or tray. Add in the chopped onions and give everything a good mix. Spread the potatoes and onions out evenly in the basket/tray and cook for a further 5-7 minutes or until nicely browned and crispy. The onions should be soft, translucent, and slightly caramelized at this point too.
  • Serve immediately as desired. Enjoy!


  • Make sure to cut the potatoes into even-sized cubes so that they cook evenly. You can also cut the spuds into wedges if you prefer.
  • Do not overcrowd the air fryer basket/tray as this will result in uneven cooking. If you have a lot of potatoes, cook them in batches.
  • If you want softer onions, cook them for longer with the potatoes. Also avoid, cutting the onions too small as it burn rather than caramelize.
  • Use any other seasoning of choice. For the classic version, use rosemary, salt, and pepper.
  • Check if the lemon pepper seasoning you are using already contains salt or not so that you can add accordingly.
