Can I bake cakes or other items in the Ninja Crispi?

The reviewer does not recommend the Crispi for baking, as the UK model lacks a dedicated bake setting. Testing with bite-sized cookies resulted in a crunchy top but a soggy bottom. It's anticipated that a cake would likely become dry on the outside before the inside is fully cooked.

What are the main limitations of the Ninja Crispi?

Key limitations include the absence of temperature controls, making it less suitable for recipes requiring precise heat adjustments. Cleaning the attached stand on the glass bowl is challenging, especially drying the area between the stand and glass. Additionally, there is no option to mute the appliance's beeps, and reheating dense dishes like cottage pie or pasta bake requires pre-microwaving to achieve the best consistency.

What kind of food does the Ninja Crispi cook best?

The Crispi truly excels at preparing dishes that benefit from a crispy finish. Homemade breaded chicken, for example, cooks perfectly, remaining moist inside while developing a satisfying crunch outside. It also delivers excellent results with frozen chips, potato snacks, green beans, asparagus, and sliced chorizo, all achieving desirable crispness.

Is it safe to use foil or parchment paper in the Ninja Crispi?

Ninja provides conflicting advice, with the manual advising against it but their website's FAQs stating it's permissible. The reviewer's recommendation is to use foil or parchment paper with caution, ensuring it is always weighted down by food to prevent it from coming into contact with the heating element, similar to best practices for conventional air fryers.

Candid Clara's Ninja Crispi Review

Q: Is the Ninja Crispi energy efficient?

The Crispi consumes 0.170 kilowatt hours of electricity for 10 minutes of use on the air fry setting, which translates to about 5 pence. If used for 20 minutes daily, seven days a week, the annual cost would be approximately £36. This is slightly more expensive compared to Ninja's AF400 dual drawer air fryer.

Source verdict

The reviewer concludes that the Ninja Crispi has addressed its initial faulty unit problems and excels at creating crispy dishes, is safe to use on worktops, and is energy efficient. However, it lacks precise temperature control, can be difficult to clean in certain areas, and performs inconsistently for baking or dense dishes like pasta bakes, which Ninja itself suggests microwaving first.

About this source

This video provides an in-depth re-review of the Ninja Crispi, a portable 4-in-1 glass air fryer, after a year since its initial launch. The reviewer conducts various cooking tests, energy efficiency assessments, and temperature tests to evaluate if previous issues have been resolved. It also explores new accessories available for the appliance.

Review notes

The Ninja Crispi is a reliable portable air fryer, with previous faulty unit issues for UK/EU models reportedly resolved, and it particularly excels at delivering crispy results. It offers excellent visibility of food during cooking and features a heat pod whose exterior frame and feet remain cool enough to be safely placed on a worktop, as confirmed by thermal camera testing. However, the appliance struggles with baking, yielding soggy-bottomed cookies and potentially dry cakes, and cleaning the space between the glass bowl and its attached stand is notably difficult. If you need a straightforward, easy-to-use air fryer for one or two people that prioritizes crispy food and visual monitoring, this product is a strong contender. If precise temperature control or superior baking performance is essential for you, look for alternative appliances.

The Crispi is a portable glass air fryer that comes with two bowls, making it great for small kitchens, caravans, or traveling.

reviewer_claimmoderate

The Crispi is non-toxic, BPA-free, and its crisper plates have a nano ceramic coating that is PFAS and PTFE free. An optional third-party stainless steel trivet, which works well for most foods, is also available.

specification_claimstrong

While Ninja states it can cook for up to four, the reviewer found the Crispi is best suited for one or two people, with the 1.4L bowl for one and the 3.8L bowl for a couple.

reviewer_claimmoderate

The appliance offers four cooking settings with a temperature range of 70° to 200°, but there is no option to see, change, or control the specific temperatures.

specification_claimstrong

Thermal camera testing showed that while the inside of the heat pod gets very hot (160C), the frame, feet, and handles remain much cooler, making it safe to place directly on a worktop.

The Crispi did an excellent job with homemade breaded chicken, resulting in a moist interior and crunchy exterior, and also performed well with frozen chips and potato snacks, highlighting its strength in creating crispy textures.

reviewer_claimstrong

While a frittata tasted good, it was too crispy outside. A pasta bake resulted in a crunchy top but liquid sauce, different from oven consistency. Baking cookies yielded a soggy bottom, and the reviewer predicts cakes would be dry outside before cooking inside.

reviewer_claimstrong

The Crispi used 0.170 kWh for 10 minutes on air fry, costing about 5p. This calculates to roughly £3 per month or £36 per year for 20 minutes of daily use.

The attached stand on the glass bowl makes it hard to clean the bottom and the gap in between. Additionally, the Crispi lacks an option to mute its beeps.
