Ninja Crispi FN101ST Review: Is This Glass Air Fryer System Worth Buying?

The Ninja Crispi FN101ST 4-in-1 Glass Air Fryer is very different from a traditional basket-style air fryer. Instead of using a fixed drawer basket, this system uses a portable Ninja Crispi PowerPod with CleanCrisp glass containers that can be used for cooking, serving, storing, and transporting food.

This model includes a 4-quart glass container, a 6-cup glass container, storage lids, crisper plates, and a container adapter. It also offers four cooking functions: Max Crisp, Bake, Air Fry, and Recrisp. With 1500 watts of power and a maximum temperature of 450°F, it is designed for small-batch meals, reheating leftovers, crisping foods, and compact everyday cooking.

On Amazon, the Ninja Crispi FN101ST has a 4.6 out of 5-star rating from 6,833 customer reviews, carries the Amazon’s Choice badge, has 9K+ bought in the past month, and ranks #5 in Air Fryers at the time of writing.

The biggest attraction of this product is not just air frying. It is the combination of glass cooking containers, portable pod-style design, nested storage, and PFAS-free cooking surface. For buyers who dislike bulky air fryers or want to avoid traditional nonstick-coated baskets, the Ninja Crispi offers a more flexible approach.

This review is based only on the product data and Amazon customer feedback provided. No unsupported testing claims, cooking times, or extra assumptions are added.

The Ninja Crispi FN101ST is best for buyers who want a compact glass air fryer system that can cook, crisp, reheat, store, and transport food in the same containers. Its strongest selling points are the CleanCrisp glassware, PFAS-free cooking surface, 450°F max temperature, and portable PowerPod design.

Amazon customer feedback is mostly positive in important areas. Customers praise its quality, ease of cleaning, ease of use, cooking performance, size, taste, and speed. Many buyers especially like that it is easier to clean than traditional air fryers and fits well in small kitchens.

However, it is not the same type of appliance as a large basket air fryer. The 6-cup container is made for personal-sized meals, while the 4-quart container is better for larger portions. Buyers who want a single large basket for big batches may prefer a traditional XL air fryer instead.

Bottom Line: The Ninja Crispi FN101ST is a smart choice for people who want a compact, glass-based, easy-clean air fryer system for small-batch meals, leftovers, meal prep, and everyday cooking. It is less ideal for buyers who mainly need extra-large batch cooking.

The Ninja Crispi FN101ST immediately feels different from standard air fryers. Instead of a bulky base with a pull-out basket, this system separates the heating pod from the cooking containers. The PowerPod sits on top of the glass container, while the food cooks inside the CleanCrisp glassware.

This design gives the product a more flexible feel. You can cook in the glass container, serve from it, add a storage lid, and store food afterward. That is one of the main reasons this product stands out from regular air fryers.

The included two-container setup is also useful. The 6-cup container is designed for smaller personal meals, while the 4-quart container is designed for larger portions. Ninja states that the 4-quart container can fit a 4-lb whole chicken with vegetables, while the 6-cup container is intended for personal-sized meals.

The product also focuses strongly on storage. The PowerPod and CleanCrisp glassware can nest together, which makes the system more cabinet-friendly than many traditional air fryers.

Overall, the first impression is clear: the Ninja Crispi FN101ST is not just trying to be another air fryer. It is designed as a compact cooking, storing, and reheating system built around glass containers.

The Ninja Crispi FN101ST includes several pieces in the box:

→ Ninja Crispi PowerPod
→ 4-QT CleanCrisp glass container
→ 6-cup CleanCrisp glass container
→ Container adapter
→ 2 storage lids
→ Crisper plates

This is one of the more complete setups compared with many basic air fryers. The two glass containers give users different portion options, while the adapter allows the PowerPod to work with both container sizes.

The storage lids are also important because they support the product’s cook-store-transport concept. Instead of moving leftovers into a separate container, users can store food in the same glass container after cooking.

The Ninja Crispi FN101ST includes four cooking functions:
→ Max Crisp
→ Bake
→ Air Fry
→ Recrisp
This function set is simple but practical. Max Crisp is focused on crispier results, Air Fry handles everyday air frying, Bake adds more flexibility, and Recrisp is useful for bringing leftovers back closer to a fresh texture.
Unlike larger air fryers with many presets, the Ninja Crispi keeps its controls focused. This makes it easier for users who want a compact cooking system without complicated settings.

The Ninja Crispi FN101ST reaches a maximum temperature of 450°F with 1500 watts of power. This gives it enough heat for crisping, reheating, and small-batch cooking.
The product is positioned around fast, high-heat cooking in a compact format. Ninja also describes the Crispi PowerPod as delivering full air fryer power in a palm-sized design.
This 450°F max temperature is one of the main reasons the product stands out from many compact reheating appliances. It is not only made to warm food; it is designed to crisp and cook food using air fryer-style heat.

The biggest difference between the Ninja Crispi FN101ST and traditional air fryers is the use of CleanCrisp borosilicate glass containers.
Instead of cooking inside a standard nonstick basket, this system uses glass containers that are designed for cooking and storing food. Ninja lists the cooking surface as PFAS free, PTFE free, and without nonstick chemical coating.
This is a major buying reason for customers who prefer glass cooking containers over traditional coated baskets. Amazon customer comments also show that many buyers specifically appreciate the glass design because it feels easier to clean and more useful for food storage.
The included containers are:
→ 4-QT CleanCrisp glass container
→ 6-cup CleanCrisp glass container
The 6-cup container is better suited for smaller personal meals, while the 4-quart container is meant for larger portions.

The Ninja Crispi FN101ST is designed around a cook-store-transport workflow. This is one of its most unique advantages compared with traditional air fryers.
The glass containers can be used for cooking, serving, storing, and transporting food. The included snap-lock lids support meal prep and leftovers, allowing users to store food without transferring it into another container.
This design is especially useful for users who want fewer dishes and a more flexible meal-prep setup. It also supports the product’s portable identity, since the smaller container can be used for personal-sized meals and on-the-go food storage.

Storage is another strong part of the Ninja Crispi design. The PowerPod and CleanCrisp glassware are made to nest together, which helps reduce cabinet space compared with many traditional air fryers.
Ninja lists the product dimensions as 13.38″D × 11.96″W × 13.58″H, and the product images highlight nested storage with a compact cabinet-friendly setup.
This does not mean it will fit in every cabinet, but compared with bulky drawer-style air fryers, the Crispi system has a more storage-focused design. For small kitchens, apartments, and users with limited counter space, this can be an important benefit.

Amazon customer feedback for cooking performance is strongly positive. According to the provided data, 318 customers mention cooking performance, with 296 positive and 22 negative comments.
Customers say the Ninja Crispi cooks food well, crisps food nicely, and works well for meals like chicken wings, vegetables, sweet potato fries, and reheated pizza slices.
The product’s 450°F max heat, Max Crisp mode, Air Fry mode, and glass container system all support its cooking-focused design. However, results can still depend on food type, amount, and user settings.
Based on the provided Amazon feedback, the Ninja Crispi performs well for small-batch meals, reheating, crisping, and everyday compact cooking.

The Ninja Crispi FN101ST uses touch controls with simple function options. Customer feedback strongly supports ease of use.
Amazon data shows 442 customers mention ease of use, with 419 positive and 23 negative comments. Buyers describe the product as easy to use, convenient for meal prep, and beginner-friendly.
This matters because the Ninja Crispi has a different design from traditional basket air fryers. Even with that different format, customers still find it simple to operate.
The clear function layout and smaller number of modes help keep the learning curve lower.

Cleaning is one of the strongest customer-approved benefits of the Ninja Crispi FN101ST.
Amazon data shows 516 customers mention ease of cleaning, with 471 positive and 45 negative comments. Customers repeatedly say the glass containers are easy to clean and that the system is easier to clean than many traditional air fryers.
The product information also states that the glass containers, crisper plates, adapter, and lids are dishwasher safe. This supports faster cleanup after cooking.
The glass design also allows users to see the food and mess more clearly, which can make cleaning feel more straightforward than cleaning a dark basket-style drawer.

Reliability is the main watch point in the customer feedback.
Amazon data shows 412 customers mention reliability, with 299 positive and 113 negative comments. Many customers say the product works well, but some negative reviews mention issues such as the unit stopping or concerns about long-term performance.
This does not mean most buyers face reliability problems, because the majority of reliability mentions are still positive. But compared with categories like ease of cleaning, ease of use, and cooking performance, reliability has a higher negative share.
For a balanced review, this should be mentioned clearly so visitors do not feel the review is only promotional.

Size feedback is mostly positive. Amazon data shows 243 customers mention size, with 211 positive and 32 negative comments.
Customers like the compact size, especially for small kitchens, two-person households, and users who do not want a bulky air fryer on the counter.
The product also supports portability with snap-lock lids and glass containers that can store or transport food. The smaller 6-cup container is especially relevant for personal-sized meals, while the 4-quart container gives more room for bigger portions.

Taste feedback is strongly positive. Amazon data shows 222 customers mention taste, with 206 positive and 16 negative comments.
Customers praise the Ninja Crispi for making food crispy and enjoyable, especially chicken wings, chicken breast, reheated pizza, and other everyday meals.
The strongest pattern in customer feedback is that users like the combination of crispy results and glass cooking. Many buyers also mention that the food cooks well without needing much oil.

Speed is another positive area. Amazon data shows 210 customers mention speed, with 192 positive and 18 negative comments.
The product listing says the 6-cup container can make personal-sized meals in just 7 minutes, excluding preheat. Customer feedback also mentions quick cooking, with some buyers saying food is ready in about 12–14 minutes.
To keep this accurate, these times should be treated as listing/customer-feedback references, not a universal result for every food. Cooking speed can vary depending on portion size, food type, and selected mode.

Yes, the Ninja Crispi FN101ST 4-in-1 Glass Air Fryer is worth considering if you want a compact air fryer system built around glass cooking, easy cleaning, and flexible food storage.
Its biggest strengths are clear:
→ CleanCrisp glass containers
→ PFAS-free and PTFE-free cooking surface

Customer feedback supports the product well. Buyers strongly praise its quality, ease of cleaning, ease of use, cooking performance, compact size, taste, and speed. These are the areas that matter most for a compact everyday air fryer system.
The main caution is reliability. Amazon data shows 412 customers mention reliability, with 299 positive and 113 negative comments. That means most reliability feedback is still positive, but the negative share is higher than categories like cleaning, use, cooking performance, and taste.
Overall, the Ninja Crispi FN101ST is a strong choice for buyers who want a smaller, cleaner, glass-based air fryer system instead of a bulky traditional basket air fryer.
