¼ cups of water or broth
Instructions
Start the recipe by preheating the air fryer to 370 degrees Fahrenheit or 3 to 5 minutes.
Cut the top of the onion and peel the outer skin and layer. Slice the onions into wedges (between ½ and ¼ inches thick).
Once they are cut, toss them in a mixing bowl and spray some oil on them.
In the meantime, blend the seasoning ingredients (salt, ground black pepper, and kosher salt) in a food blender to make a fine powder. Next, transfer the oiled onions to a bowl with the prepared mixture. Toss everything together to make sure all the onions are coated with the seasoning.
Transfer the onions to the air fryer basket in a single layer. Pour the water or broth on the onions.
Cook the mixture in the air fryer for about 15 to 20 minutes at 370 degrees Fahrenheit. Stir the onions with a silicone spatula or tongs halfway through the cooking time (7 to 10 minutes).
First, cook them for 15 minutes and see whether they are to your desired taste and caramelization. If not, cook for another 5 minutes for the right degree of crispiness.
Once the time is over, remove them from the air fryer basket and enjoy.
Notes
Always cook in batches and do not overcrowd the air fryer, especially if you have a smaller one. This is because too much content in the air fryer basket can make the cooking slow and uneven.
Adjust the time down for the second batch, as the air fryer is already too hot. You do not need 10 minutes for the second or third batch.
Though some air fryer models do not recommend preheating, I always preheat the appliance for 2 to 3 minutes. It helps you with a crispy exterior.
To get crispy onions from the air fryer, it is always better to spray the onions with olive oil, avocado oil, or any neutral oil. It not only adds a brown color to the onion but also prevents the non-stick surface of your air fryer basket from getting damaged.
For extra crispiness, you can cook the onions a few minutes longer. But be careful not to burn them. You also need to consider the efficiency of your specific air fryer model; mine just do this in the additional 5 minutes.
