Ninja crispi 3.8l portable air fryer: Was £179.99, now £119.99, Amazon.co.uk
Save £60 on the Ninja crispi air fryer, one of the brand's latest releases. This space-saving appliance delivers full-size air fryer power in a compact, portable design that is ideal for smaller kitchens, student living or weekends away. Our senior tech critic, Alex Lee, put it to the test earlier in the year and was seriously impressed, calling the glass cooking container a "game changer" for letting you watch your food crisp to perfection.
Ninja foodi max 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 creami: Was £199.99, now £149.99, Amazon.co.uk
If the July heat has you craving cool and refreshing desserts, you're in luck. Ninja’s creami has 25 per cent in the Prime Day sale. Designed to whip up homemade smoothies, ice creams, sorbets and more, the appliance proved “pretty fool-proof" when we put it to the test, and it comes complete with three tubs for making batches and storing them in the freezer with ease.
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 stainless steel 30cm frying pan: Was £59.99, now £39.99, Amazon.co.uk
A great Amazon Prime Day deal is one offering a top product – that you needed anyway – at a reasonable price. If you’re currently losing a significant portion of your dinner to a weathered “non-stick” pan, this Ninja deal ticks all three boxes. It sits atop our roundup of the best non-stick frying pans, and benefits from a chunky 33 per cent Prime Day discount.
Ninja staysharp 6-piece knife set: Was £179.99, now £119.99, 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. I’ve 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 compact blender is perfect if you're tight on kitchen storage space. Plus, thanks to USB charging, you can take it to the gym for your post-workout protein shake. Our tester’s banana and berries smoothie “came out perfectly” and they even managed to whip up some pancake batter in it. With a 24 per cent discount for Prime Day, it’s only a few pounds off its cheapest ever price.
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, IndyBest deputy editor Alex found 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, with 20 per cent off Ninja’s woodfire electric outdoor oven for Prime Day. There are preset settings for different pizzas, including 'artisan', which our reviewer said had a “lovely charred taste and crispy crust”. You can also opt for a “moist and chewy” New York style or even a calzone.
Ninja two-in-one detect power blender pro: Was £199, now £149.99, 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 43 per cent, so now’s a good time to nab a discount.
Ninja foodi 9-in-1 possible pan: Was £129.99, now £74.99, Amazon.co.uk
If you don’t have the space to stack multiple saucepans and frying pans, the Ninja possible pan could be the solution. The brand claims that you can steam, simmer, roast, braise, bake, saute, sear, boil and fry with its multipurpose pan, saving you precious kitchen space.
IndyBest reviewer, Lois Borny, pitted the possible pan against its coveted non-stick rival, the Our Place always pan. Her favourite was Ninja's version, with its durability winning her over. “Given that the Ninja possible pan can handle metal utensils and high heat, it seems to be more equipped to deal with the bumps, scrapes and conditions that come with everyday cooking,” she said. It’s not the cheapest that it’s ever been, but with 42 per off, you’ll still get a decent discount.
Ninja foodi three-in-one toaster grill and panini press: Was £149.99, now £109.99, Amazon.co.uk
A three-figure fee for a toaster may raise some eyebrows, but this clever contraption validates its price tag. Not only does it occupy the number one spot in our guide to the best toasters, but it also serves the function of a grill and panini press. “If you love sourdough or other toasting bread, you’ll love how easily long slices fit into this toaster,” our tester Rachael writes. “It has seven settings, to ensure you get your preferred crispness, while the grill function is ideal for open-faced sandwiches and quick snacks.”
