What can you cook in a Ninja Foodi 9-in-1 Multi-Cooker 6L OP350UK?
Just about everything. Using the different lids for different functions, you can cook complete meals without having to reach for pans. For instance, a chicken pot pie can be made from scratch using the sear function to soften ingredients like onion, carrots and celery. You don’t need to cover the air fryer with a lid for this. After adding stock and the chicken, you will then pressure cook it for a few minutes with the pressure cook lid. When this is done, you’ll add the sauce-based ingredients to the pot and sauté this once more for a few minutes. The final step uses the crisping lid to grill the pastry crust you’ve placed over the filling.
We included this abridged recipe to demonstrate the different processes and lids you’ll need to learn about on your Foodi journey. You’ll need to learn its ways but it will be worth it if you’ll be using it often.
Ninja’s 29-page guide gives you a few other popular recipes including desserts, dehydrated beef jerky and homemade vanilla yoghurt; we just wish it had more.
The 6-litre capacity is more than enough for a family of 4 as it can take a whole chicken, or a 1.5kg leg of lamb, or 2kg pork shoulder or 1kg of potatoes. It can also cook grains, pasta and pulses which several air fryers we reviewed can’t handle.
Finally, it’s one of the only air fryers that can cook a proper curry laden with sauce. Hallelujah! The slow-cook or pressure-cook functions are designed for sauced-based meals. The Ninja 7-in-1 OP450UK and the Instant Pot Duo Crisp are great alternatives out of those we’ve reviewed.
How big is the Ninja Foodi 9-in-1 Multi-Cooker 6L OP350UK?
It’s a tank. Coming in at 11kg, it’s slightly lighter than its cousin – the Ninja OP450UK multi-cooker. So you won’t want to be moving it around, and you probably won’t be if you’ve bought it for cooking most dishes.
At 36cm deep, there’s ample room behind for ventilation. But its height and width will take up a lot of your counter space. When the lid is closed the height is a manageable 32cm but when open it shoots up to 53cm which is likely to clatter into hanging cabinets. The crisping lid doesn’t detach either.
It’s the second widest air fryer we’ve reviewed, at 43cm – only the Russell Hobbs Air Fry Mini Oven is wider. The increased size is down to the functions rather than its capacity, as there are other 6-litre fryers that are far narrower, such as the Instant Vortex 6.
Is the Ninja Foodi 9-in-1 Multi-Cooker 6L OP350UK convenient to use?
The short power cord is definitely limiting. At 50cm, it’s the shortest we’ve seen and you may even need an extension for it to reach your wall socket.
After preheating for 5 minutes the Ninja Foodi is ready to make an entire meal, so that’s a minor hitch for a major result.
No Ninja air fryers are transparent, nor do they have presets or a rotating element. You won’t be able to hit a button to make a specific dish. Multi-faceted dishes will require more than one function too, so it’s best you have the instruction manual and recipe guide to hand.
Presets wouldn’t work with this machine – there are too many buttons already. A viewing window would have been handy for checking on the roast, but you’ll have to open the crisping lid instead. What’s good is that you can open the lid whilst something is air frying to toss or turn whatever’s inside. Cooking resumes once you’ve closed it again. The manual says for extra crispy results you should toss the food, but this is not necessary.
Cleaning the beast is easier than you think as most of its parts are dishwasher-safe. This is much better than the Russell Hobbs Air Fry Express Mini Oven which is of a similar size but tougher to scrub.
Ninja Foodi 9-in-1 Multi-Cooker 6L OP350UK customer reviews
This Foodi has excellent reviews on Amazon, Currys and John Lewis.
Many owners have ventured into the exotic functions of dehydrate, slow cook and yoghurt-making and have loved them. The more usual air fryer functions generally get a thumbs up in customer reviews. Criticism focuses on the bulky size, and some users found the machine too loud.

Our verdict: Is Ninja Foodi 9-in-1 Multi-Cooker 6L OP350UK any good?
This Ninja earned a “Finder Recommended” accolade because it’s our top pick for foodies. If you’re not afraid to get stuck into new dishes or ways of cooking then this is a great bit of kit for your kitchen. You just need to get used to the functions and lids. But if you don’t like reading the manual before using an appliance, we fear this machine will push your patience.
The OP350UK is hugely versatile, but it’s also… huge. You won’t be shifting it from cupboard to counter every time you want to use it. Make sure you have space and a conveniently placed socket before getting one.

Expert review
Foodies, this one’s for you. You may never have to use a hob again with the Ninja Foodi 9-in-1. It seems to do it all: pressure cook, air fry, slow cook, steam, bake/roast, sear/sauté, grill, make yoghurt and dehydrate. We make that 11 functions.
So if you’re looking for a simple air fryer, this won’t be your first choice. But if you’re adventurous in the kitchen and don’t want to wash up a stack of pots and pans after cooking chips followed by a roast followed by stew and so on – then this machine is a godsend. But make some time in the diary as this cooker will take a bit of getting used to.
It’s a big beast, too, and that’s not accounting for the non-detachable crisper lid that opens upwards, so kitchen space and cabinet clearance are key considerations.
