Ninja Combi Multicooker review – after a year in my kitchen, this non-toxic air fryer has pretty much replaced my oven

Ninja Combi Multicooker on the countertop with food in front of it.

In my time as one of Homes & Garden's kitchen experts, I've seen it all. I've tested the steamers, slow cookers, air fryers, toaster ovens, and countertop ovens. The Ninja Combi Multicooker claims to condense all these functions (and more) into one, simple appliance. It makes big promises, but does it deliver on them?

I put the Ninja Combi oven on my countertop to run it through a series of tests across the range of functions on offer. The test was only supposed to last for a day, but I kept it there and I kept it there and I kept it there until two weeks had passed. It quickly became my sous chef. Or, I should say, I became its sous chef. Now, I've had it for over a year and it has pretty much replaced my oven.
