Ingredients
  

  • 2 Onions
  • 1 Teaspoon Spices
  • ½ Teaspoon Salt
  • ½ Teaspoon Pepper
  • 1 Tabelspoon Vegetable Oil

Instructions
 

  • Slice onions thinly, about ⅛ to ¼ inch thick. Place into a bowl.
  • Season the onions with spices, salt and pepper and toss with oil.
  • Place in an air fryer-safe baking dish or basket lined with foil.
  • Air fry at 300°F (150°C) for 25–30 minutes, stirring every 8–10 minutes, until golden and soft.
  • Place the caramelized onions into a bowl ready to use.

Notes

  • Use a shallow dish or foil basket: This prevents slices from flying around in the air fryer and helps them cook down properly.
  • Stir often: Stirring every 8–10 minutes is key to even caramelization—don’t skip it or you’ll get uneven browning.
  • Don’t overcrowd: Cook in batches if needed. Too many onions at once will steam rather than caramelize.
  • Watch near the end: The last 5 minutes can go from golden to burnt quickly—check frequently for that sweet spot of color and softness.
