The Ninja Crispi isn't your typical air fryer – and its unique design makes it worth the price

Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System: one-minute review

The Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System is just that. It is indeed an air fryer, and not really more than that, but the design is utterly unique. Rather than cooking in a plastic drawer, your food goes on a metal tray in a glass cooking container with built-in plastic handles and feet. The heating element, which Ninja calls the PowerPod, is placed onto the glass container. When your cooking is complete, simply remove the PowerPod and place the glass container right onto the table for serving.

If you have leftovers, you can just put the included lid on your glass container and stick it in your fridge. The glass containers come in multiple sizes and the PowerPod has an adapter so it will fit on each container perfectly. There are four cooking modes: Bake, Air Fry, Max Crisp, and Recrisp. Each runs at a different temperature range, so you have some flexibility.

Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System: price and availability

• List price: $159.99 (about £127 / AU$251)

You can purchase the Ninja Crispi directly from Ninja’s website, where it’s available in a number of bundles containing multiple glass containers. You can also purchase extra glass containers in three different sizes separately: $29.99 for the six-cup container, $39.99 for the 2.5-quart container, and $44.99 for the four-quart size. The standard $159.99 system, which I tested, comes with the large four quart and the small six cup glass container. It’s available just about everywhere that sells air fryers online and in person, such as Amazon, Best Buy, Target, Walmart, and many more.

Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System: design and features

• Heat comes from removable Crispi PowerPod
• Four cooking functions
• Looks functional rather than attractive

The cleverly designed Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System is a really a cooking pod, called the PowerPod, and a collection of glass cooking dishes. The cooking dishes, which Ninja calls TempWare Containers, withstand high cooking temperatures and are made just for the Ninja Crispi. You must use Ninja’s TempWare Containers; the PowerPod won’t work on other dishes. A built-in plastic piece adds handles and feet so you can place the dishes on any countertop. Each cooking dish comes with a metal crisper plate that nests inside and keeps the food off the bottom so air can circulate around it.

Place your food into one of the glass dishes on the crisper plate and place the pod on top. The PowerPod fits the small six-cup dish perfectly on its own. If you’re using the larger four-quart dish, you’ll need to use the included adapter for the PowerPod. Choose your cooking function mode: Recrisp (380°-400°F), Bake (375°-400°F), Air Fry (400°-425F), or Max Crisp (425°-450°). Select your cook time by pressing the - or + buttons. Press the start button to begin.

As with most air fryers, you will usually need to flip your food over halfway through the cook time. To pause cooking, simply remove the PowerPod and it will power off automatically. To re-start cooking, place the pod back onto the glass container and hit the start button once again.

The standard bundle comes with the largest glass dish, which has a four quart capacity, and the smallest one, which holds six cups. Ninja also makes a medium 2.5-quart glass dish, which is sold separately. Any of the glass dishes can be purchased separately, and there are different bundles you can buy with varying dish combinations. The handles and feet allow you to use the dishes for serving the food; there’s no need to transfer it to another container. All of the cooking dishes also come with an air-tight lid, so you can use the dishes for storing food as well.

Cleaning the Ninja Crispi is easy. You don’t need to clean the PowerPod, just the glass containers and crisper plates. They are even dishwasher safe, though it is easy enough to just wash them by hand. Though it’s not mentioned in the literature, I was able to use paper air fryer liners which made cleanup even easier.

Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System: performance

Though there are four cooking modes, the Ninja Crispi is truly an air fryer. The Air Fryer, Max Crisp, and Recrisp modes all worked pretty much as expected. The Bake mode, however, was a bit disappointing. I tried baking several items, all of which turned out fully browned on the top and raw in the middle. Since air frying in general requires flipping for even crisping, I’m not that surprised that the baking mode wasn’t great. I think baking would be fine for something quite thin, like cookies or very small mini muffins. If you want to make something thicker, like full-sized cupcakes, you’re better off using a regular oven. Of course, most people don’t buy air fryers in order to bake.

I eat a lot of fresh roasted vegetables, so I air fried broccoli, cauliflower, red peppers, brussels sprouts, and sweet potatoes. I used both Air Fry and Max Crisp modes. There is a learning curve, but once I got the hang of it, the veggies turned out delicious with just the barest spritz of oil. You definitely want to remember to flip your food, at least once during the cooking process. When I didn’t flip it, the food did not cook evenly. The Ninja Crispi is very, very fast. It’s a good idea to check your food frequently to make sure you don’t burn it. Even with careful flipping and checking, vegetables tend to brown (or blacken) quickly in some spots before all of them are fully cooked. Raw vegetables tended to come out more blackened and crisp rather than tender.

My favorite vegetable cooked from its raw state was the diced sweet potatoes. They were crisp on the outside and soft in the middle. The next day I used the Recrisp mode to heat up the leftovers, which turned out great.

I made a bunch of veggie burgers, as well as protein waffles, veggie tots, falafel balls, and veggie “chicken” nuggets. They all turned out wonderful and crisp on the outside, tender on the inside. I didn’t need to add any oil to any of these convenience foods.

I hosted a Super Bowl party and air fried some frozen french fries for my guests. The fries disappeared so quickly, I ended up air frying another batch immediately! They were perfectly crisp and evenly browned on the outside and soft and fluffy in the middle. I did nothing to doctor them at all, no oil or seasonings, and they came out just right.

My family got in on the air frying fun. My youngest is a more adventurous cook than I, and they made some panko-crusted and seasoned tofu squares. The tofu was delicious! As expected, it was nice and crunchy on the outside and soft in the middle. They didn’t even have to press and dry the tofu first. I’m a vegetarian but my husband eats meat; he used the Ninja Crispi to quickly and easily cook some chicken breasts. They got nicely browned on the outside (flipping half-way through cook time is a must) and cooked all the way through.

As I mentioned above, I did try Bake mode. First, I made some pancake bites in a little silicone baking dish. The tops browned but the rest was still raw. I actually pulled off all the tops, flipped them over, and put them through another bake cycle. That worked fine. I also baked a (rather thick) protein air fryer cookie with the same results. I did the same thing where I pulled off the top, flipped it over, and put it through another cycle. Again, it was fine that way. So if you do use Bake mode, just be sure your items are very thin.

How I tested the Ninja Crispi 4-in-1 Portable Glass Air Fryer Cooking System

• I tested Recrisp, Bake, Air Fry, and Max Crisp modes multiple times
• I used it daily for two weeks to cook a variety of food
• I cleaned it after each use

Although I’m a foodie, I’m kind of a lazy cook. As a wife and mother of three, I used to put more effort into crafting a variety of nutritious meals from scratch when my kids were little. Now that they’re grown, I still want to eat healthy meals, I just don’t want to take the time to cook them. The Ninja Crispi certainly helps me get food on the table fast. My family (my husband, my adult child, and I) used the Ninja Crispi daily, sometimes multiple times in one day, for two weeks. We made loads of fresh veggies, plus veggie burgers, veggie chicken nuggets, french fries, frozen waffles, breaded tofu, falafel, veggie tots, chicken breasts, pancake bites, and a protein breakfast cookie. I cleaned it after each use, which was quite easy. I did use paper air fryer liners sometimes, which made cleanup even easier.
