I like using the air fryer to cook food without oil. Since I'm trying to reduce fat in my diet and I love french fries, the air fryer is working for me. I cooked thin frozen french fries, and they tasted good to me, the help with my french fry fix. I have also cooked frozen chicken tenders and they turned out fine. When cooking fresh burgers, thin patties will cook quicker. it took longer to cook a fresh beef burger because of the thickness. I had to cut the burger in half to make sure the center was cooked completely. I have ordered the fry/grill pan to use with the air fryer.
