We have an “el cheapo” air fryer which I bought online for around $100 a few years ago and it has been fantastic.
My wife uses it to cook our McCains Shoestring Fries which are ready in no time.
We use it to cook frozen pies and Ingham’s Buffalo Wings after preheating them in the microwave for a few minutes followed by around 7-10 minutes in the air fryer.
When we cook a roast dinner, we always have plenty of meat and roast veggies for the next few nights, and my wife reheats the roast veggies in the air fryer.
It draws around the same amount of electricity as our wall oven but it has finished cooking before the oven has even reached the temperature setting of 180 to 200 degrees, thus using considerably less power as well as being much faster.
