Onions In Air Fryer
When you are stood there, queueing for your hot dog at a hot dog stand, what kind of toppings do you choose?
I love loads of fried onions (the more the better) along with plenty of ketchup and mustard. Whilst the rest of our family is just a bit of ketchup and they are done!
The worst thing though, is where I like to get them (30 mins from where we live) there is a big seagull problem and they always want to steal the hot dogs, I panic and cover myself in ketchup. Then if you can visualise me in a white top and you can imagine the state of me!!!
But back to those onions in air fryer. If like me you love a hot dog with onion, then these fried onions are perfect. I recently shared my air fryer hot dogs recipe and how long to cook hot dogs in air fryer, and it included the onions, but what if you don’t just want fried onions for hotdogs?
That is when this air fried onions recipe is perfect for you. You can use it alongside our air fryer ground beef recipe (mince here in the UK) our air fryer lasagna, or even our air fryer chilli con carne.

Can You Air Fry Onions?
Yes, you can air fry onions and they are so easy too and also less calories compared to frying onions in a frying pan.

Should You Fry Onions In Oil?
Its common to fry onions in oil for that wonderful crispy texture. But if you are on a diet and want to cut the calories, when you air fry onions, they require a lot less oil.
But to answer your question, to fry onions you do need oil otherwise they will be very dry and wont go crispy.

Seasonings – This is optional, but you can add some salt and pepper, or a favourite seasoning, to flavour your onion with.
