  • 1 large onion yellow or sweet vidalia
  • 1 tbsp olive oil
  • 1 tsp salt or to taste


  • Preheat the air fryer to 350 degrees F for 5 minutes.
  • Peel the onion and slice pieces into about 1/4 of an inch thick.
  • Transfer the sliced onion into a mixing bowl and add olive oil and salt.
  • Toss the onions to completely coat in the oil and salt mixture.
  • Transfer to the air fryer and cook at 350 degrees F for 12-15 minutes, opening the air fryer every 4-5 minutes to shake or toss the onions so they cook evenly.
  • Top your favorite burger or sandwich and enjoy.


  • This recipe works well with yellow onions or sweet vidalia onions.
  • Make sure to shake or toss the onions throughout the cooking process for even cooking.
  • Add additional spices according to taste. Sometimes I sprinkle some of this KFC spice blend on top of my air fried onions.
  • Cooking time may vary depending on your air fryer’s brand, adjust accordingly.
  • Always read your air fryer manual before using it.
