Ninja FN101ST Review: What I Learned About This Glass Air Fryer

I went into this Ninja FN101ST Review expecting another small air fryer with a new look. It is not. The Crispi takes a very different path. Instead of a normal basket and a large plastic body, it uses a small PowerPod on top of glass cooking containers.

That design caught my attention because the same glass container can cook food, hold leftovers, and go into the fridge. The FN101ST also gives you a small 6-cup container and a larger 4-quart container. After looking closely at the design, specs, and owner feedback, I think its biggest appeal is simple: it tries to make quick cooking and food storage part of the same routine.

Ninja FN101ST Review

What Is the Ninja FN101ST?

The Ninja FN101ST is the Ninja Crispi 4-in-1 Glass Air Fryer. It uses a 1,500-watt PowerPod with two glass containers. You can use Air Fry, Max Crisp, Bake, or Recrisp modes. The system reaches up to 450°F.

What makes it unusual is the lack of a normal air fryer drawer. The PowerPod sits above the glass container. This gives the FN101ST a compact, pod-style design.

The glass containers are also made for storage. They come with snap-lock lids, so you can cook food and save leftovers without moving them to a new dish. The containers are listed as microwave-, freezer-, and dishwasher-safe.

That is the part of this air fryer I find most interesting.

Why the Glass Design Matters More Than the Air Fryer Modes

At first, the four cooking modes sound like the main story. They are useful, but I don’t think they are what makes the FN101ST stand out.

The real difference is the glass cooking system.

A normal air fryer usually has a coated basket. You cook the food, remove it, wash the basket, and put leftovers into another container. The Crispi tries to remove some of those steps.

The same container can cook and store food

Imagine making chicken and vegetables for dinner. You can cook them in the 4-quart glass container, let the food cool, add the storage lid, and put the container in the fridge.

The next day, you can use the Recrisp setting to warm the food and bring back some of the crisp texture.

This is a small change, but it can make a real difference if you cook small meals often.

Ninja FN101ST 4-Quart vs. 6-Cup: Which Size Makes More Sense?

This was one of the first things I would look at before buying. The two containers serve different jobs.

The 6-cup container is better suited to personal meals, small sides, snacks, and leftovers. The 4-quart container gives you much more room for a larger meal or a small batch. Ninja also lists the larger container as being able to fit a 4-pound whole chicken.

The 6-cup container is the everyday size

For one person, the smaller container can make more sense than firing up a large air fryer.

It is useful for foods such as fries, vegetables, chicken pieces, frozen snacks, or a single serving of leftovers. The smaller space can also help when you don’t want to cook a huge batch.

The 4-quart container is better for meal prep

The larger container is where the FN101ST becomes more useful for couples or small households.

You have more room for chicken, vegetables, potatoes, and other small-batch meals. Still, I would not confuse 4 quarts with a huge family air fryer.

If you usually cook…Better container
One person’s meal6-cup
Small snack or side6-cup
Leftovers6-cup or 4-quart
Several servings4-quart
Small meal prep batch4-quart

One owner review on Lowe’s made an important point: even the 4-quart container can feel limited for larger pieces of meat. One reviewer said two large chicken thighs filled much of the available space.

That is a useful reminder not to shop by the number “4-quart” alone.

How Well Does the Ninja FN101ST Cook?

The owner feedback I found is quite consistent on one point: people like the cooking results.

Lowe’s customer feedback reports strong comments about crisp fries, chicken wings, reheated leftovers, and even cooking. The current Lowe’s listing shows a 4.7/5 rating from more than 600 reviews, although some reviews may be incentivized.

I also found owner reports describing the FN101ST as fast for everyday foods. One recent reviewer said many foods were done in about 10 minutes. That is an individual experience, though, not a guaranteed cooking time.

Air Fry is the main workhorse

Air Fry is the setting I would expect to use most.

It suits foods that need hot circulating air and a crisp outside. Think potatoes, chicken, vegetables, frozen snacks, and similar foods.

The trick with any air fryer is not to pack the food too tightly. Air needs room to move.

Max Crisp is for when you want more crunch

Max Crisp is useful when regular Air Fry is not giving you enough browning.

I would use it for foods where crisp texture matters most. I would not treat it as the default mode for every meal.

Recrisp may be the most underrated mode

This is the setting I think deserves more attention.

Microwaves are great at making food hot. They are not great at keeping fried food crisp.

Recrisp gives you another way to handle pizza, fries, roasted vegetables, and other leftovers that have gone soft.

One owner described using the larger container for a batch of sweet potatoes and then recrisping portions the next morning. That is exactly the sort of routine where this design starts to make sense.

What I Like About the Ninja FN101ST

After comparing the design with owner feedback, several things stand out.

The glass containers solve a real kitchen problem

I like products that remove steps rather than simply adding features. The FN101ST does that with its cooking and storage containers.

You don’t have to think, “Where will I put these leftovers?”

You already have the container.

It is easier to see the food

The glass design also gives you a clear view of what is cooking. That can help when you are learning how quickly a food browns.

Instead of opening a dark basket again and again, you can see what is happening.

The system is easier to store than a large air fryer

The PowerPod and containers are designed to nest together. That matters if you do not want a large appliance living on your counter all day.

Where the Ninja FN101ST Could Frustrate You

This is where I think a useful review needs to be honest.

The FN101ST is clever, but clever designs often come with trade-offs.

You get less temperature control than some air fryers

The Crispi is built around preset cooking modes rather than giving you the same kind of manual control you may find on a conventional air fryer.

That makes it simple.

It can also feel limiting if you enjoy changing temperature and time for every recipe.

Some owner feedback specifically mentions wanting more temperature customization.

The glass is heavier than a normal basket

Glass has benefits, but it is still glass.

If you are used to pulling out a lightweight metal or plastic-coated basket, the container will feel different. You also need to handle it with reasonable care.

This is not a major problem. It is simply part of choosing a glass cooking system.

The PowerPod needs attention

This is one issue I would not ignore.

Because the heating element sits above the food, greasy cooking can send splatter toward the PowerPod. Owner feedback has mentioned the need to clean the top after messy foods.

That means “dishwasher-safe container” does not mean the entire appliance is maintenance-free.

I would get into the habit of wiping the PowerPod after greasy cooking.

Common Ninja FN101ST Mistakes I Would Avoid

The first few uses are where small habits can make a big difference.

MistakeBetter approach
Overfilling the glass containerLeave room for air to move
Treating 4 quarts like a huge fryerPlan for small to medium batches
Ignoring the PowerPodWipe it after greasy meals
Using one setting for everythingMatch the mode to the food
Guessing every cooking timeStart with the guide, then adjust

Don’t chase the shortest cooking time

One of the easiest mistakes with an air fryer is assuming that a short time always means better cooking.

It does not.

Frozen foods vary. Chicken pieces vary. Cut vegetables vary. Even the amount of food in the container changes the result.

I would rather start with the suggested time and check the food than keep adding a huge batch and hoping the same time works.

Don’t crowd the food

This is especially important with the larger container.

Air frying depends on hot air reaching the food. If everything is piled together, the food may cook but not crisp as well.

This is one of those boring lessons that saves a lot of frustration.

Is the Ninja FN101ST Easy to Clean?

This is one of the strongest parts of the design.

The glass containers and several other parts are dishwasher-safe. Owner feedback also frequently praises the glass for being easy to wash.

The important distinction is that easy-clean containers do not mean you can ignore the PowerPod.

The glass does most of the cleanup work

The cooking container is removable, so you are not trying to scrub food from a large built-in appliance.

That alone can make the cleanup routine feel less annoying.

Greasy meals need more care

Chicken skin, bacon, sausages, and other fatty foods can create splatter.

I would not let grease sit on the PowerPod. A quick wipe after cooking is much easier than dealing with old grease later.

Is the Ninja FN101ST Good for Meal Prep?

Yes, this is one of the most logical reasons to consider it.

The glass containers are designed to move from cooking to storage. The included lids make that process easier. The freezer, microwave, and dishwasher-safe claims also make the containers more useful beyond air frying.

Meal-prep needHow FN101ST fits
Cook a small batch4-quart container
Store leftoversSnap-lock lid
Reheat foodRecrisp or other cooking mode
Wash upDishwasher-safe parts

The system makes the most sense for someone who regularly cooks a meal, saves part of it, and wants the leftovers to taste better the next day.

That is a more specific use case than simply saying “this is a good air fryer.”

Ninja FN101ST vs. a Normal Basket Air Fryer

The two designs solve slightly different problems.

A traditional air fryer is often better if your main goal is maximum cooking space and familiar controls. The FN101ST makes more sense if glass storage and compact design matter to you.

FeatureFN101STTypical basket air fryer
Cooking vesselGlassBasket
Food storageBuilt into systemUsually separate
View foodClear glassOften limited
Temperature controlMode-basedOften more manual
Storage designNesting systemLarger appliance body

I would not call one design universally better.

If you cook large batches every day, a bigger conventional air fryer may fit your routine better.

If you cook smaller meals and hate transferring leftovers into storage containers, the Crispi has a clear advantage.

What the Owner Feedback Tells Me

I always like to look beyond product specs because specs cannot tell you how an appliance feels after a few weeks.

Current Lowe’s feedback is strongly positive. Reviewers repeatedly mention crisp food, easy cleaning, glass containers, compact storage, and simple operation. The same feedback also includes some complaints about the desire for more temperature control.

There are also reports of practical quirks, such as crisper trays sometimes feeling less secure or needing careful placement. These reports are not proof that every unit has the issue, but they are worth knowing before buying.

That is the kind of detail I would rather know before spending money than discover after the box is already open.

Who Should Consider the Ninja FN101ST?

The FN101ST makes the most sense for people who value the whole system, not just the air-frying function.

You are…Why it may fit
Cooking for one6-cup container is handy
Cooking for two4-quart size offers more room
Short on counter spacePod design is compact
Into meal prepCook and store in glass
Reheating leftovers oftenRecrisp is useful

It can also suit someone who wants to avoid a traditional nonstick air fryer cooking basket. The product listing describes the glass containers as PFAS- and PTFE-free.

Who May Want a Different Air Fryer?

I would look elsewhere if your first priority is a very large cooking area.

The same applies if you want lots of manual temperature control. The FN101ST is designed around a simple preset approach.

And if you dislike handling glass, this may not be the right format for you.

If your priority is…Think twice about FN101ST if…
Very large mealsYou often cook big family batches
Full manual controlYou adjust temperature often
Light cookwareYou dislike heavier glass containers
Zero cleanupYou do not want to wipe the PowerPod

Is the Ninja FN101ST Worth It?

For me, the most important question is not whether the FN101ST can air fry. Of course it can.

The better question is whether its glass cooking and storage system matches the way you eat.

If you make small meals, reheat leftovers often, and like the idea of cooking directly in glass, the design has a lot going for it. Owner feedback also supports the idea that the Crispi can deliver fast, crisp results while keeping cleanup fairly simple.

But I would not buy it just because the design looks clever.

Think about your normal portions first. If you regularly cook large amounts of food, the 4-quart container may feel smaller than you expect.

Ninja FN101ST Review

My Final Take on the Ninja FN101ST

After digging into the design, specifications, and current owner feedback, I think the biggest lesson is that the Ninja FN101ST is more than an air fryer. Its real value comes from combining cooking, reheating, serving, and food storage in one glass-based system.

I also would not ignore its limits. The capacity is still modest, manual control is not its strong point, and the PowerPod needs some care after greasy cooking. But if your daily routine is built around quick meals, small batches, and leftovers, those trade-offs may be easy to live with.

The FN101ST is not trying to replace every kitchen appliance. It is trying to make a few common jobs simpler. And from the owner feedback I reviewed, that simple idea is exactly why many people seem to like it.
