  • Place onions in a medium bowl. Pour in olive oil, vinegar, salt, pepper, and rosemary. Toss to coat.  
  • Transfer the seasoned onions to the air fryer basket.
  •  Set the air fryer to 400°F for 18-20 minutes or until onions are tender and lightly charred, stirring once or twice during the cook time. 


  • Use frozen pearl onions. Do not thaw them before you start. The steam from the thawing onions helps them cook.
  • Use the sweetest balsamic vinegar you have at hand.
  • You can mix up all the ingredients ahead of time and put the mixture in the fridge until you are ready to cook.
  • I used this air fryer to make these onions.
  • This is the balsamic vinegar I used.
