As many have, I use a main built in fan oven with smaller non fan oven/grill above. I have a slow cooker and also a micro / combi oven. Looking at Ninja but there is a bewildering choice. They seem to cook quite small lots at once. And the new Ninja Max you can only cook one thing at a time? So today I have a chicken in the slow cooker rather than roast, but would love roast potatoes but don’t want to put my main oven on. Which air fryer type of gadget would work best? Thank you 🤗
