Our Full Product Review:
Ninja’s unique TenderCrisp Technology and 9 cooking settings allow you to be as creative as you want. You can cook and crisp a large 2kg roast chicken, which is perfect for up to 4 people.
Having an air fryer with a variety of cooking options and settings is so amazing. The Ninja 9-in-1 Multi-Cooker fulfils all your needs when preparing for a family buffet. You can choose from air crisp to grill settings to make perfectly golden chips, chicken breasts, and lots more.
Like other air fryers, the Air fryer mode allows you to prepare healthy air fryer meals such as chicken wings, golden chips, mac n’ cheese, and 75% less oil. You can look forward to a juicy, crispy, and succulent guilt-free meal that everyone falls in love with.
The only downside to using this mode is that you can only prepare about two portions of chips (500g maximum capacity). We also recommend that you shuffle the cooking halfway, which requires simply lifting the lid and using a pair of tongs. This will help you achieve individually sealed and crispy chips.
The Slow cook mode is ideal for making your risottos and casseroles.
The Pressure cook mode is excellent for creating an assortment of one-pot recipes such as spaghetti, curries, and lots more. If you haven’t pressure cooked before, your purchase will also come with an illustrative guide that would guide you every step of the way.
The Bake/Roast mode is excellent for baking fresh bread, cakes, pies, or crispy Mediterranean vegetables. When you want to dehydrate herbs and vegetable crisps, it does the job perfectly well with the Dehydrate mode.
The Sear/Saute mode allows you to create magnificent sauce bases. I especially love the yoghurt mode, which is a second reason (besides all nine cooking methods in one) this air fryer stands out from the crowd. With this Ninja Foodi air fryer, you can create homemade yoghurt bass, smoothies, healthy vegetables, and lots more.
You will also love the Grill mode, which is perfect for making enough grilled parmesan chicken drumsticks or burgers for a bit of evening fiesta with friends. However, you cannot grill more than two chicken breasts on the rack because the height is limiting. It would help if you also had a pair of tongs to turn your meat from side to side for even charring.
There’s also a dedicated Steam mode for making healthy veggies, cooking rice, and lots more. Plus, You can also efficiently heat food without defrosting and keep food warm for up to 12 hours.
However, a beginner might find this machine a little overwhelming at first. Fortunately, it comes with a small chef-created recipe guide, so you can try out simple meals and get to know your newfound air fryer. Again, the recipe guide is excellent if you’ve only used traditional cooking equipment like an oven. The air fryer is powerful and delivers a lot more speed and performance than conventional devices, so your average temperature and timings wouldn’t work here. For instance, if you air-fry homemade chips using the same time and temperature as a fan oven, you might have a rock hard and unpalatable result.
Using the chef-recipe guide will also help you figure out how to adjust your meal timings and temperatures. It would help if you didn’t also take the timings and temperatures on the guide as gospel. When it’s a few minutes close to the normal time (on the chef guide), I recommend taking off the lid to ensure your food doesn’t overcook.
Sturdy Industrial design
Perhaps, one reason some people choose other air fryers over it is that it’s not attractive. Besides looking black and greyish in many different corners, it also comes with bulky lids, which means you might not adequately tuck and use it underneath the kitchen cupboard.
First, it comes with two lids, one that’s fitted and another for pressure cooking (and slow cooking). The fitted lid is permanently hinged to the cooker, which means you can only open it to a certain angle but cannot detach it. This lid works for air frying, roasting, and even grilling. Still, this lid makes it difficult to fit your cooker into just about any space.
The second lid is for pressure cooking and slow cooking and is completely removable.
Secondly, you will find a sizable 6L cooking pot, detachable crisping basket, and two grilling racks with your purchase.
Nevertheless, you can liken it to an ugly mini oven that takes a lot of space. However, if you can overlook the somewhat unattractive design, you will love the enormous capacity it provides.
Intuitive control
What the Ninja Foodi 9-in-1 Multi-cooker OP350UK lacks in aesthetics, it makes up for in intuitive control. The oversized design ensures you have a big and totally obvious digital panel. When you think that this air fryer has over nine cooking options, you will find that having a display that makes it easier to keep track of what’s happening inside your air fryer is important.
There you can find buttons to start/stop, Keep Warm, Pressure, Steam, Slow Cook, Air fry, Sear/Saute, Grill, and Bake/Roast. All controls are carefully labelled, making it easier to set up without issues. However, you need to select the cooking type, time, and temperature manually each time you want to use the machine. There are no pre-programmed settings on this air fryer which is a surprise and a shortcoming.
So you might spend a little time learning all about the machine.
Super-fast cooking
The Ninja OPO350UK is remarkably fast. It comes with Ninja’s proprietary TenderCrisp technology that makes it easier to cook foods up to 70 percent faster than classic cooking times with superb results. This works whether you are pressure cooking, creating delectable one-pot recipes, or merely air frying, reheating, or steaming food.
Wide temperature and time range
The Ninja Foodi Air fryer also comes with an hour-long timer, and you can cook as high as 210oCelsius, without any troubles.
Generous capacity
The Ninja air fryer cooker is big enough to cook a large family without fuss. Although it takes up a large amount of space and isn’t meant for a tiny kitchen, you will love having all your cooking needs catered by a single gadget. Think about what would have happened if you had to get a pressure cooker, air fryer, instant pot, and other options this air fryer delivers as different gadgets.
You will also love the practical and sturdy handles that make it easier to move your air fryer. It equally has silicone non-slip feet to keep your air fryer just as stable.
Our Verdict:
The Ninja Foodi 9-in-1 Multi-Cooker 6L OP350UK is a perfect choice for anyone intending to cook for large families (minimum 4) or party guests and loves the idea of having an air fryer, instant pot, slow cooker, and pressure cooker in one single gadget. You’ll find that having a single gadget that can do all of this fits better than having all three functions as individual gadgets on your kitchen counter. Some individuals and smaller families also swear by this cooker, mainly because of this combo. Overall, having a cooker that lets you create various dishes without investing in multiple cooking gadgets is absolutely perfect.
