Ninja Crispi 4-in-1 Review: A Clever Glass Fryer for Two

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

The Ninja Crispi 4-in-1 Glass Air Fryer splits an air fryer in two. A detachable PowerPod holds the heater, fan and four buttons, and it sits on top of a glass container that you cook in, serve from and then lid for the fridge. The kit comes with a 6-cup container for a single portion and a 3.8 L (4-quart) one that Ninja says fits a 1.8 kg (4-lb) chicken, each with its own crisper plate and storage lid. It makes the most sense for one or two people and small kitchens.

The glass is the reason to buy it over a regular basket fryer: you watch food brown without pulling anything out, and leftovers never change dishes. In Canada it’s the FN101CGY, sold and shipped by Amazon.ca, and Ninja Canada lists the same two containers, 1.4 L and 3.8 L (6 cups and 4 quarts), in borosilicate glass it describes as thermal shock resistant, with a 1-year limited warranty. Ninja Canada also sells the Crispi Pro, which keeps the glass but sits on a fixed countertop base with a temperature dial, so the real question is which compromises suit your kitchen. Below, the cooking results come first, because that’s where the tests split.

Ninja Crispi 4-in-1 Glass Air Fryer Cooking Results

The lab test and the kitchen tests don’t agree here, and both are worth knowing. In RTINGS’ standardized fry test, less than half of each batch came out crisp and the rest stayed undercooked. The 6-cup container did a little better, at 43.3% crispy fries, but more than half of that batch was still undercooked or burnt, and RTINGS points readers who want more even frying to the Crispi Pro, though Prudent Reviews, cooking the same foods in both side by side, found the results nearly identical.

Everyday cooking went better. Frozen fries and roasted vegetables turned out crisp and well browned in several home tests. Prudent Reviews had chicken wings fully cooked in 23 minutes, against 15 for the Ninja Air Fryer Pro and 25 for the COSORI TurboBlaze and Instant Vortex Plus in the same test. The catch is attention. Shaking or flipping halfway through makes a real difference here, since Homes & Gardens found food at the edges tends to cook a bit faster. Even with regular flipping, TechRadar saw raw vegetables blacken in spots before the rest was done.

It’s quick, too: RTINGS found it preheats very quickly, though the manual says preheating isn’t needed. Baking is hit and miss. TechRadar’s pancake bites and thick protein cookie, and Prudent Reviews’ cookies, browned on top while the middle or bottom stayed raw, which is what you’d expect when all the heat comes from the pod above; Tech Advisor’s cookies, baked one at a time, came out well in 4 to 5 minutes, if a little dark. Large roasts stretch it too. Tech Advisor’s whole chicken took about 70 minutes and the skin never crisped, though the meat stayed moist.

Controls and Heat Settings

There are four buttons: one to cycle through the modes, plus and minus for the timer, and start. Each mode runs its own heat range: Air Fry at 205 to 220°C (400 to 425°F), Bake at 190 to 205°C (375 to 400°F), Recrisp at 195 to 205°C (380 to 400°F) and Max Crisp at 220 to 230°C (425 to 450°F).

That simplicity has a cost. There is no temperature control beyond picking a mode, and the coolest preset starts at 190°C (375°F). A recipe written for 175°C (350°F) means choosing the nearest mode and adjusting the time, and RTINGS notes it isn’t ideal for low-heat jobs like dehydrating or proofing dough. Lifting the PowerPod pauses cooking, so checking food is easy; set it back down and press start to carry on.

Capacity and the Glass Containers

Quarts flatter this design. Prudent Reviews measured the 3.8 L (4-quart) container’s crisper plate at about 20 by 20 cm (8 by 8 inches), or roughly 413 cm² (64 square inches), enough for about 11 wings or four overlapping slices of bread, and the 1.4 L (6-cup) container at about 213 cm² (33 square inches), or roughly six wings. For comparison, the same reviewer measured about 497 cm² (77 square inches) in the 5.7 L (6-quart) COSORI TurboBlaze and 568 cm² (88 square inches) in the 5.7 L (6-quart) Instant Vortex Plus, and found the bigger Crispi Pro’s plate no larger than this one’s.

The containers are what you’re paying for. Each gets a lid, so dinner goes into the fridge in the dish it cooked in and comes back out for the Recrisp mode. Testing the UK version, Tom’s Guide reheated a creamy pasta in the glass in 15 minutes, slower than a microwave but browned and bubbling on top.

Cleanup is mostly a dishwasher job: the glass, crisper plates and lids all go in, and the PowerPod only needs a wipe. Two details are worth knowing. Food and water can collect in a narrow gap where the plastic base meets the glass, and the food itself sits on a crisper plate with a ceramic nonstick coating rather than on the glass.

Footprint, Storage and Handling the PowerPod

Counter space is where the Crispi wins. Prudent Reviews measured its footprint at about 723 cm² (112 square inches), the smallest of the seven air fryers it tested, and the containers, plates and pod nest together so the whole kit can live in a cupboard. Testers split on portability: Prudent Reviews and Homes & Gardens found the kit too heavy to carry around in a bag, while TechRadar suggests leaving the PowerPod at work and bringing only the glass container with your food.

The pod needs somewhere to go each time you lift it. Its heating coils sit on the underside, about 5 cm (two inches) above the counter on fixed heat-safe feet, and Prudent Reviews wasn’t comfortable with that near paper towels or packaging. On bare granite, its measurements showed the counter warming by only about 4°C (8°F) after a 10-minute cook. The glass itself ran above 88°C (190°F) and stayed hot for five to ten minutes, and the large container weighs 1.9 kg (4.2 pounds), so two hands and a pair of mitts are the safe habit. Noise is reasonable: it measured 62 dBA, quieter than the Crispi Pro’s 67 dBA, though the Instant Vortex Plus ran at 55 dBA in the same reviewer’s tests.

How Does It Stack Up Against the Competition?

The Crispi’s real rivals are Ninja’s own glass step-up and conventional basket fryers, which give you more cooking area and adjustable heat but no glass dish to serve and store in.

Ninja Crispi 4-in-1 Glass Air Fryer: Worth It for Cooking for One or Two

It earns its place in a small Canadian household that likes the cook-serve-store routine: a lunch in the 1.4 L dish, dinner for two in the 3.8 L one, the lid on whatever’s left and Recrisp the next day without moving it to another dish. In October 2026, with both on sale at Amazon.ca, it cost $159.99 CAD against $329.99 CAD for the Crispi Pro, and Amazon.ca’s list prices of $219.99 and $399.99 CAD keep a similar gap, so the original is the cheaper way into glass air frying here whichever price you catch. Fries and roasted vegetables came out well in the home tests, and the kit packs into a cupboard when you need the counter back.

Not everyone who tested it would buy it. Prudent Reviews, which tested it against six other fryers, would skip it, mainly because the hot PowerPod has to be set down on the counter each time you check the food, and points most buyers to a basket fryer such as the Instant Vortex Plus or COSORI TurboBlaze. That is also the answer if you regularly feed three or more, since a 5.7 L (6-quart) basket gives you more cooking area. The Crispi Pro is the glass option if you want exact temperatures, a dehydrate mode or a heating element fixed in the base instead of a pod you lift off, which is why Prudent Reviews prefers it of the two; its cooking plate is no larger and it bakes no better. If you’d rather stay with Ninja, our Ninja Air Fryer Pro 4-in-1 review covers its conventional 4.7 L (5-quart) basket model.
