Ninja double stack XL air fryer: Was £269.99, now £184.99, Amazon.co.uk
If you can’t squeeze another appliance onto your kitchen countertops, Ninja’s double stack XL air fryer is a fantastic choice. The innovative design sees the dual drawers stacked, making the most of the vertical space in your kitchen. Our reviewer found that the cooking process was a tad more involved but overall the results were good. “Once I’d resigned myself to the fact I’d need to stay on standby for regular shaking duties”, they wrote, “I was able to cook chips evenly and quickly”.
Amazon has slashed the price of the air fryer by more than 30 per cent for Prime Day. It’s rare to see it fall to this price at the online retailer, so now’s a good time to snap it up.
Ninja foodi dual zone digital air fryer: Was £239.99, now £153.99, Amazon.co.uk
Ninja’s dual zone air fryer, which has six cooking functions and a generous 9.5l capacity, has been reduced by £85 for Prime Day. Our reviewer wrote that it feels “like one of Ninja’s most well-thought-out appliances” with “every cooking setting you could possibly need”. We’ve only seen it drop to this price once before, in the lead-up to Christmas, so now’s a good chance to snap up the offer.
Ninja thirsti water bottle and flask: Was £34.99, now £21.99, Amazon.co.uk
Like other vacuum flasks, the Ninja thirsti is designed to keep drinks hot and cold. However, it can even retain fizz for an entire day – perfect for keeping hydrated during the summer heatwaves.
Ninja foodi possiblecooker 8-in-1 slow cooker: Was £149.99, now £109.99, Amazon.co.uk
Thanks to Amazon Prime Day, the Ninja foodi possiblecooker has a generous 27 per cent off in the copper and black colourway. With this clever appliance, you can sear, steam, braise, simmer, bake, prove, slow cook and keep your food warm.
Ninja foodi max 14-in-1 multi cooker: Was £309.99, now £199.99, Amazon.co.uk
As you might expect from the name, Ninja’s multi-cooker provides you with a number of different ways to cook your favourite dishes or experiment with new recipes. From pressure and slow cooking to grilling, steaming and baking, it also allows you to air fry, dehydrate, sear and even make yoghurt, all in one device.
It’s certainly an investment, but thanks to Amazon’s Prime Day discount, you can get more than £100 off. I haven’t seen it fall any lower than this sale price, so now’s a good chance to save on the appliance.
Ninja perfect temperature kettle: Was £99.99, now £67.99, Amazon.co.uk
Our best temperature control kettle for hi-tech design now has more than 30 per cent off in the Prime Day sale. While it’s not the lowest price we’ve ever seen for this kettle, it’s still a decent saving of £32. There are six temperature buttons for all your standard hot drinks, as well as more precise settings that allow you to set the temperature between increments from 40C to 100C. Our reviewer praised its “swanky design” and, after a little practice with its various settings, found it “incredibly easy to use”.
Ninja zerostick ceramic pro 5-piece pan set: Was £269.99, now £169.99, Amazon.co.uk
If your pots and pans have seen better days or are a bit of a mismatched mess in your kitchen drawers, there’s currently a massive £100 off Ninja’s bestselling zerostick ceramic pro 5-piece pan set. Consisting of two frying pans, a milk pan, as well as two saucepans with glass lids, it’s a great starter kit to help you whip up some of your favourite dishes and meals.
Ninja says its pans are safe to use alongside metal utensils and heat-proof up to 350°C, so you don’t need to worry about them chipping or scratching as you use them.
Ninja staysharp 6-piece knife set: Was £189.99, now £131.99, Amazon.co.uk
Shopping for the best kitchen knife sets? Ninja’s staysharp knife block took the title of the best set with a sharpener, with it getting high praise from our tester. As well as five kitchen knives, this set also comes with a pair of scissors.
The integrated sharpener “means you’ll always have super-sharp knives with little effort”, according to our reviewer. Ninja says they should last you at least 10 years if you sharpen them regularly. Our consumer editor, Sabrina, has had the set for just over two years, and with regular sharpening, they work just as well as the day she started using them.
Ninja blast portable blender: Was £49.99, now £38, Amazon.co.uk
This clever little blender is perfect for the gym or if you’re tight on storage space. Unlike a big kitchen blender, it does everything in one bottle, so you can mix a protein smoothie without having to transfer anything. It’s surprisingly powerful, too. It can’t match a full-size blender when blending tough ingredients like ice, but our tester found that a banana and berries protein smoothie “came out perfectly”.
Ninja woodfire grill xl bundle: Was £539.99, now £399.99, Amazon.co.uk
I’ve spotted a great deal on this outdoor grill and smoker. For the same price as the standalone grill (was £449.99, now £399, Amazon.co.uk), you can get a bundle that includes a two-probe thermometer, a rib rack, a cover, liners & and a cleaning brush. This remarkable grill is the rare electric barbecue that can rival full-size gas and charcoal models. Best of all, it has a smoker, so you can make delicious ribs and brisket.
Ninja slushi frozen drinks maker: Was £349.99, now £307, Amazon.co.uk
This 12 per cent discount doesn’t look huge, but it will save you £42.99 on one of Ninja’s most coveted appliances. In his test, deputy IndyBest editor Alex found that it made some of the best drinks he’s ever tested, turning out perfect slushies, frappes, and frozen cocktails. One of his few criticisms was the high price, so any saving could be worth snapping up for a delicious way to beat the heatwave.
Ninja woodfire electric outdoor oven: Was £349.99, now £279.99, Amazon.co.uk
Get ready to impress your garden party guests this summer as there’s currently 20 per cent off Ninja’s woodfire electric outdoor oven this Prime Day. Our pizza oven tester was “very impressed” with the preset settings for a variety of different pizzas, helping you to make everything from New York pizzas to calzones.
Ninja two-in-one detect power blender pro: Was £199.99, now £104.99, Amazon.co.uk
Ninja blenders always perform well on test – the Ninja foodi power blender three-in-one (was £169.99, now £149, Amazon.co.uk) tops our list of the best blenders. This model has both brains and brawn, automatically detecting the ingredients and portion size of your soon-to-be liquid then adjusting its speed, time and pulse accordingly to deliver the desired results. A look at its Amazon history tells us that the detect power blender pro’s lowest ever price was £101.40, so this is a solid deal.
Ninja foodi max pro health grill: Was £299.99, now £169.99, Amazon.co.uk
Ninja’s foodi max pro grill can grill everything from steaks to veggie kebabs, plus you can use it to air fry, roast, bake, dehydrate and more. When our reviewer tested the original foodi max grill, which has slightly fewer functions, they were “bowled over by its ease of use, speedy cooking and fantastic results”.
Amazon has slashed the price of the grill by 21 per cent, so now’s a good time to nab a discount.
Ninja foodi 3-in-1 hand blender: Was £129.99, now £84.55, Amazon.co.uk
Whether you want to blend smoothies or chop veg, this Ninja hand blender has a versatile range of attachments for different kitchen tasks. I love its whisk attachment for whipping cream, and I can’t fault its power and simple design that makes it easy to switch out the different components. It’s currently on a limited-time offer with 31 per cent off, so nab it while you can.
Ninja FrostVault 42l insulated cool box: Was £319.99, now £229.99, Amazon.co.uk
There’s no better time to invest in a premium cool box than now. With a huge £90 saving on the Ninja frostvault, you can take all your essentials camping or to festivals with no worries of anything going warm. This heavy-duty cool box comes on wheels for easy manoeuvring, and the brand claims that it can store ice for up to two days.
