Ninja’s new glass air fryer is revolutionary - it's non-toxic, super simple, and better than any oven

When Ninja first introduced the original Ninja Crispi to their already impressive collection of air fryers last year, we thought it couldn't be topped. The promises of multiple size capacities and functions, a savvy way to store straight from cooking to fridge, and the fact that you could see your food while it cooked seemed unbeatable – until we heard about the Ninja Crispi Pro Countertop Glass Air Fryer. A bigger, better version.

As a standfast anti-air-frying cook, I was more than happy to put this shiny new model to the test after seeing the original Crispi’s credentials, to see if my stance on the best air fryers could be changed.

It's safe to say, it's completely transformed how I cook. I've only used my oven once in a month of testing – and that was only to boil pasta. I'm an air fryer convert, and I'll never go back as long as the 'Crispi' exists.

Ninja Crispi Pro 7-in-1 Air Fryer: Specifications

Ninja Crispi Pro 7-in-1 Air Fryer Review: Who would it suit?

Firstly, it would suit those who are keen to use a non-toxic air fryer, because of the glass and ceramic elements of the design, both of which are natural non-stick materials that avoid the problem of coated plastic.

Secondly, it would suit those who want more than merely air frying. For budding home chefs, the 7 different settings give far more flexibility in the things you can cook in an air fryer, from baked goods to jerky. The expanded cooking functions include: Air Fry, Bake, Re-Crisp, Max Crisp, plus new Prove, Roast, Dehydrate with temperatures up to 230°C.

Thanks to the XL capacity 5.7L CleanCrisp glassware dish, it can cater for up to 6 people in one sitting, making it ideal for families who require maximum space.

It would also suit beginners, like me. I was starting to feel like the only person on the planet who hadn't used an air fryer; it became somewhat of a standing joke. But in truth, it was a lack of confidence whereby I didn't trust the process of closing the drawer, with no way of evaluating the results without constantly interrupting the airflow. Thanks to the glass, that is no longer a problem.

The Ninja Cripsi Pro’s sleek glass construction and choice of stylish colourways make it ideal for those who want a design feature, rather than something to hide away – the clean lines and modern proportions make it perfect for kitchens where style matters as much as practicality.

Unboxing

The problem with large capacity air fryers is the space they take up on the countertop, but thanks to the glassware and elevated stand on the remodelled Crispi Pro XL air fryer, that isn't a problem. It feels very streamlined, considering the size.

5.7L & 2.3L CleanCrisp Glassware, Removable Modular Base, 2 Crisper Plates, 2 Storage Lids & Recipe Guide. There's also the option to buy a 3.8L CleanCrisp Glassware separately.

The large 5.7L dish can hold a whole roast chicken with seasonal vegetables, while the smaller 2.3L container is perfect for sides, snacks or smaller portions (ideal for single meals).

What is it like to use?

As someone who has never used an air fryer before, I'm the best candidate to validate how easy this model is to use. The controls are simple but intuitive. You simply hit the button to select a mode or time and twist the dial to adjust the setting. It's quick, easy and produces brilliant cooking results every time.

For me, the glass base makes the whole experience less air-fryer-like because you can assess the cooking results by eye, which, for me, is key to how I instinctively prefer to cook. It’s been a game-changer for saving me from accidentally burning food just because I couldn’t see into the air fryer.

Test 1: roasted vegetables

The best thing about cooking vegetables in an air fryer is the lack of oil involved, meaning they never feel soggy or greasy. I cook a lot of roasted vegetables, pretty much a staple of all my meals, so I was keen to test this out first.

For me, the glass base comes in especially handy when you’re cooking vegetables, so you can get a real sense of how long they need. At first, I spent far too long peering through the sides, eagerly watching how fast the ingredients were cooking. This ability to see the results as they cooked allowed me greater control over the browning process when roasting vegetables.

I've now got it down to a fine art of chopping the veg and adding the peppers, onions and leeks in first (very lightly tossed in oil) and at a later stage, 5 minutes into cooking, scattering in broccoli for a further 4 minutes – that was the one I watched most to avoid it burning. While the standard air fryer mode is great, I prefer using the roast setting to produce tender but caramelised, delicious roasted veg.

Test 2: chips

I've been told countless times that chips and air fryers go hand in hand, so I was looking forward to seeing what all the fuss was about. Turns out it's true, the power of an air fryer ensures frozen chips are beautifully crispy on the outside while remaining light and fluffy on the inside, and all in under 15 minutes – very impressive.

For my first serving of chips, I used the standard air fryer mode to cook the chips from frozen, following the 15-minute suggested cooking time, but in all honesty, they were perfectly cooked by 11 minutes.

For my second batch, I used the Max-crisp setting, which produced the perfect cook chip in my opinion, golden brown and crispy on the outside but beautifully light and fluffy in the middle. This air fryer is exceptional for cooking ingredients that benefit from a crispy exterior, such as chips, salmon and even chicken.

Test 3: frozen food

I can't remember the last I ate fish fingers, but after testing them and seeing how well they turned out they might be a weekly occurrence in my household from now on.

Straight from freezer to plate in 9 minutes, I served the most beautifully crips fish fingers. I used the standard air fryer mode the first time around to get these perfect results, then for the second batch I used the Max Crisp function which enhance the crunch-factor and saved a whole minute – meaning they were ready to serve in 8 minutes.

Test 4: reheating pizza

The gentle 'reheat' mode on an air fryer is the best way to warm leftovers, as opposed to a microwave or oven. Especially pizza, because you want to retain the crunch on the crust while keeping the base soft, all while keeping your ingredients well-hydrated. This is exactly why we put pizza to the test, because it is tricky to get the balance of crunch and doughy dough.

It passed this test with flying colours, the pizza tasted as good on the second time round as it did when it was freshly cooked. The larger dish comfortably fits in a medium-sized pizza (although whoever has that much left over?). In 9 minutes, the contents had cooked right through.

Test 5: Nachos

I'm told that most air fryers are not great with wet food types, so I was keen to test the chilli nachos recipe from The Ultimate Air Fryer Cookbook by Clare Andrews. The beauty of having two different-sized glassware dishes meant I could prep the beans, tomatoes and veg in one using it as merely a baking dish, while browning the chicken in the large dish using the Crispi plate to help circulate the air.

Once all the ingredients were ready, to finish off with a layer of tortilla chips and a layer of cheese, I transferred them all back into the large 5.7L dish (the recipe catered for 4).

This dish was a prime example of when the Tupperware-style element comes in handy because I was able to serve the meal straight to the table, thanks to the glassware dish with counter-safe feet. Then, when there were leftovers that had sufficently cooled, I was able to pop the lid on and store them in the fridge to reheat the next day. Which, by the way, worked a treat – thanks to the

Cleaning

Forget worrying about the steps involved in cleaning an air fryer; this model takes little to no effort at all. While the main parts are dishwasher safe, I prefer washing by hand to avoid any potential damage. Plus, there's the satisfaction of watching the grease and residue slide off the non-stick 'CleanCrisp' glassware.

As for the detachable Crispi plates, Ninja has developed a special ceramic coating that’s both non-stick and non-toxic, so you don’t need to put any elbow grease into cleaning - I merely leave all the components to soak for 10 mins, and it wipes away with ease every time.

How does it compare?

Before the Pro, we had the original, smaller, portable Ninja Crispi. This revolutionary air fryer was the first of its kind with the glassware and Tupperware-style storage elements. So how does this model compare to the original?

The original Ninja Crispi revolutionised air frying thanks to its innovative glass container system. The non-toxic CleanCrisp Glassware design offers both cooking and storage, and its clear construction gives cooks full visibility of their food throughout the process — from preparation to plating.

The new-improved Ninja Crispi Pro Countertop Glass Air Fryer now has the added option for manual temperature control, expanding the system's capabilities by introducing Prove, Roast, and Dehydrate functions, delivering a total of 7 versatile cooking settings. It also offers a larger capacity glass container, which makes it ideal for family meals of up to six people.

James Kitto, Senior Vice President EMEA at SharkNinja, says: “We've listened intently since the original Crispi launch, and the Ctispi Pro is our answer for the family kitchen. Our expert engineering team has pushed boundaries, culminating in the impressive ability to cook a full roast in one go.”

Should you buy it?

In short, yes. As soon as I saw Ninja's original Crispi with the glass base, I was persuaded to finally try air frying and the reason why I feel this new-improved model is best is the added capacity. This new-improved model offers a removable modular base, more cooking functions and two different-sized glassware dishes. It's more expensive, but it feels more like a permanent fixture for kitchens - whereas the original Ninja Crispi is better for portable use.

How we test

At woman&home, we put air fryers through their paces to make sure they live up to the hype, and to ensure every model is held to the same standards – budget or blowout. Every air fryer is reviewed for at least two weeks in our own kitchens, where we use it for everyday cooking to see how well it performs.

We start with four key tests to make the comparisons fair:

• Cooking frozen chips to check crispiness and even cooking
• Air-frying frozen fish fingers to assess speed and consistency
• Roasting vegetables to see how well they caramelise and retain moisture
• Reheating pizza to test how evenly it revives leftovers.

These tasks give us a solid understanding of how well the air fryer handles different types of food and everyday meal tasks.

Once the basics are covered, we can experiment with more recipes to see what different settings each model offers. By the end of testing, we will determine exactly who this air fryer is best for and how it compares to other models in terms of performance, features, and value for money.
