The Ninja Crispi is a worthwhile purchase for 1-2 people seeking an energy-efficient air fryer primarily for crispy foods, boasting a non-toxic design. However, be aware of its lack of temperature control and cleaning nuances.
The Ninja Crispi, a portable 4-in-1 glass air fryer, is highlighted for its non-toxic, BPA-free design and energy efficiency, costing about £3 per month for daily use. While it performs well for crispy dishes like chicken and chips, its capacity is better suited for 1-2 people despite claims for four. Key limitations include the absence of precise temperature control on UK/EU models and inconsistent results for baking or dense foods.
The Ninja Crispi is a commendable option for individuals or couples seeking an energy-efficient air fryer primarily for crispy foods. Its strong performance in this area, combined with safety features, makes it appealing. However, potential buyers should be aware of its limitations: the lack of precise temperature control restricts its versatility for diverse cooking tasks, and its capacity is not ideal for larger households. The cleaning challenge around the bowl stand is also a practical consideration.

The Ninja Crispi (specifically the 4-in-1 Glass Air Fryer) is consistently recognized as the top glass air fryer in major US buying guides, earning the 'Best Glass' designation in Good Housekeeping's 2026 Amazon list and its 2024 Ninja-specific test. It received a high score of 9.2/10 from CNET, which called it their 'favorite by far,' and was highlighted by The New York Times Wirecutter as a preferred alternative to larger units. While not the overall 'Best Overall' winner (which typically goes to the Ninja Air Fryer Pro XL or Max XL), it holds a strong niche position as the leading glass-model option.
Recommendation status: top pick.
Fit: excellent
The Ninja Crispi is exceptionally well-suited for preparing crispy foods like chicken, chips, and quick snacks, delivering consistent and satisfying results for daily use.
Fit: good
Its actual cooking capacity is ideal for individuals or couples, providing sufficient space for portion sizes suitable for one or two servings.
Fit: excellent
The use of non-toxic, BPA-free materials supports healthier cooking practices, ensuring food is prepared without harmful chemical exposure.
Fit: poor
The lack of precise temperature control and inconsistent results for baking or dense dishes make the Crispi poorly suited for versatile baking or roasting tasks.
Fit: poor
The absence of a mute option for the appliance's beeps means it cannot operate silently, which may be a significant drawback for noise-sensitive environments.
The Ninja Crispi is marketed as non-toxic, BPA-free, and features PFAS and PTFE-free nano ceramic coated crisper plates. Furthermore, thermal testing by the reviewer showed that while the inside gets hot, the exterior frame and handles remain cool enough, making the heat pod safe to place directly on kitchen worktops after cooking.
The Ninja Crispi comes with two bowls: a 1.4L bowl perfect for one person and a 3.8L bowl suitable for a couple. The reviewer explicitly contradicts Ninja's claim that it can cook for up to four people, stating it's better for one or two.
The Ninja Crispi (UK/EU model) has four different cooking settings with approximate temperatures ranging from 70° to 200°. However, there is no functionality to see, change, or control the exact temperature, a feature that is available on the Crispi Pro model.
The Crispi performs excellently with foods needing a crispy finish, such as homemade breaded chicken and frozen chips. However, for dishes like frittatas, it can make the outside too crispy, and for pasta bakes, it leaves the sauce liquid while crisping the top. Baking cookies resulted in a soggy bottom, and it's generally not recommended for cakes. Ninja advises microwaving dense foods first before using the Crispi for crisping.
The crisper plate, bowl, and lid are all dishwasher safe, and the Power Pod should be cleaned by hand after every use. However, the reviewer noted that the stand attached to the glass bowl makes it hard to clean the bottom of the bowl and the space in between the stand and the glass bowl, as it's difficult to get completely dry.
The reviewer measured the Crispi using 0.170 kilowatt-hours of electricity for 10 minutes on air fry, costing approximately 5 pence. This extrapolates to about £3 per month or £36 per year if used for 20 minutes daily, 7 days a week, making it an energy-efficient appliance.
The main drawbacks highlighted are the difficulty in cleaning the bottom of the glass bowl and the gap around its attached stand, the absence of a mute option for the appliance's beeps, and the lack of precise temperature control, which some users might prefer. Additionally, it's not ideal for baking or fully reheating dense items like pasta bakes without pre-microwaving.
