Best Ninja deals in Amazon Prime Day 2025, from air fryers to pizza ovens – UK Times

We’re now more than halfway through Amazon Prime Day 2026 and, as the UK bakes through yet another heatwave, anything that doesn’t turn the kitchen into an oven in itself is having a moment. If you’ve hit the stage where the idea of switching on the oven is completely off the table and the air fryer is doing all the heavy lifting, you’re definitely not alone.

So, it’s no surprise Ninja’s Prime Day discounts have been popular, and many have caught my eye. The brand’s air fryers remain some of the most in-demand appliances during major sales events, thanks to their ability to cook quickly while using less energy and producing far less heat than a traditional oven. And then there’s the Ninja creami, which feels like an absolute lifesaver in this weather, making it easy to churn out everything from frozen yoghurt to homemade ice cream without leaving the comfort of your own home.

With a day of the sale still to go, prices are continuing to shift and stock levels are starting to fluctuate. I’ll be keeping a close eye on the latest Ninja deals, highlighting any offers worth flocking to as Prime Day continues.

The best Ninja deals in the Amazon Prime Day 2026 sale are:

The idea of being able to keep drinks icy cold is particularly appealing during this heatwave, and Ninja’s thirsti has been designed to do just that. The insulated flask is touted as being able to keep cold drinks cold for up to 24 hours and hot drinks hot for up to 12 hours. Plus, the stainless steel interior is said to help prevent sparkling drinks from losing their fizz. Even better, you can now save up to 20 per cent on the 700ml version in the Amazon Prime Day sale.

Save £40 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 and was seriously impressed, calling the glass cooking container a “game changer” for letting you watch your food crisp to perfection.

Ninja’s dual zone air fryer, which has six cooking functions and a generous 9.5l capacity, has been reduced by 31 per cent 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”. This is a sizzling saving, so now’s a good chance to snap up the offer.

This is the lowest price the Ninja speedi has seen in the past year. With a £90 discount, you can save on its 12-in-1 functionality, meaning you’ll save on counter space, too. Our testers haven’t penned a review of the device yet but, as you can likely tell from this sales guide, we’re big fans of the brand as a whole. Plus, with 5.7L of space, you’ll be able to use the multi-cooker for up to four people, making it perfect for families.

Ninja’s double stack air fryer is currently on sale for its lowest price since July 2025, with a discount of £80. In her double stack review, appliance expert Katie Gregory described the device as a “a strong, space-saving option for smaller kitchens.” It comes with 6 cooking presets, separate temperature zones and dishwasher-safe parts.

If an iced coffee is calling your name amid the sweltering temperatures, then you’re certainly in luck, with our reviewer’s best buy coffee machine reduced by more than £100 for Prime Day. In her guide to the best coffee machines, appliance expert Rachael Penn dubbed the Ninja luxe premier “an espresso, filter and cold brew machine all wrapped up in one neat, shiny package.” “Shots have been rich, consistent and well balanced with proper crema, whilst the dual froth milk system steams and froths at the same time for silky, café worthy foam,” she added. Secure yours while stocks last.

If the heat has you craving cool and refreshing desserts, you’re in luck. Ninja’s creami has £30 off 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.

Our best temperature control kettle for hi-tech design now has 40 per cent off in the Prime Day sale. 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”.

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.

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 32 per cent discount for Prime Day, this is a tasty saving.

Tuck into a tasty 24 per cent discount on Ninja’s artisan electric outdoor oven for Prime Day. In her best pizza ovens review, home appliances expert Rachael Penn gave this model full marks. She said: “I think even professional pizza chefs would’ve been blown away by the results.” With four pre-programmed settings, it can create 12in pizzas to enjoy al fresco this summer and beyond.

Ninja blenders always perform well on test – the Ninja foodi power blender three-in-one 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.

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 dropped the price of the grill by a modest 8 per cent, so now’s a good time to nab a discount.
