I replaced this as a replacement for our air fryer, although good, its capacity was limiting to one of two pieces of food.
I had tried halogen ovens, which were OK but the food generally got sunburnt on top whilst raw under neither. Yes, I could have messed around with foil but who wants that faff?
I got the NuWave oven and although the first item - frozen 12-inch pizza - welded itself to the cooking rack, I found if you preheated the oven and low rack for 5 minutes on high, then put the pizza in to cook it doesn't stick and nicely cooks the bottom. They do say you're meant to cook the pizza upside down first then flip it. You may get the base extra crispy but I find my method works fine for me.
I was surprised the maximum temperature the oven got to was 177C, but everything seems to cook just fine. I especially like the delay function, load up the oven and set the delay and then cook time - it's as easy as that.
I've done stuffed crusted frozen and fresh pizza using the 5-minute prehead on high using the low rack.
Jacket/baked potatoes 2 x large, rolled in a coating of oil and sprinkled in salt, used the delay for 1.5 hours, cooking the dish for 1 hour on high.
Sticky toffee pudding - admittedly shop-bought, not homemade.
Halloumi fries and burgers, burgers on the top, wrap fries in the cooking dish on the low rack.
Generally, I use the low rack for anything you'd would in a normal oven and the high rack for anything you'd grill.
The only point out I'd give is place the dome back on the base when complete - can't leave it on its stand as the manual says it may warp the shape.
Once the oven has cooled down I leave the cooking dish/racks to soak in hot soapy water to loosen anything baked on. Clean up is then washing it off, drying, and setup for next time.
Bottom Line: Yes, I would recommend this to a friend
