Our verdict

The FlexDrawer is Ninja's most versatile air fryer. Its game-changing removable divider lets you switch between two independent 5.2L zones for dual cooking OR one massive 10.4L MegaZone for larger items like a whole chicken or leg of lamb. Seven cooking functions include Air Fry, Max Crisp, Roast, Bake, Reheat, Dehydrate and Prove (for bread dough). It cooks up to 65% faster than a fan oven. If you regularly batch-cook or have a larger family, the FlexDrawer's adaptability is unmatched.

Who should buy the Ninja Foodi FlexDrawer AF500UK?

A good fit if you…

  • cook for a larger family or batch-cook for the week
  • want to roast a whole chicken or a joint as well as cook two dishes at once
  • bake bread and want a Prove function for dough
  • want one appliance that can replace the oven for most meals

Look elsewhere if you…

  • have a small kitchen – it's the largest Ninja in our line-up
  • cook for one or two, where a 6L single basket will do the job for far less
  • are on a tight budget – the Ninja AF400UK covers dual-zone cooking for less

Pros

  • ✓MegaZone fits a whole chicken
  • ✓Most versatile air fryer on the market
  • ✓Excellent crisping and roasting
  • ✓7 functions including dough proving
  • ✓Dishwasher-safe components

Cons

  • ✗Expensive
  • ✗Very large — needs significant worktop space
  • ✗No viewing window
  • ✗Single large zone not truly "dual" temperature

My Experience with the Ninja Foodi FlexDrawer 10.4L

This section is my personal experience as an owner. It is separate from the research-led verdict and score above, which it does not change.

My own photos of my FlexDrawer

With the divider fitted, the drawer splits into two separate zones, so you can cook two different foods at once.

The Ninja Foodi FlexDrawer 10.4L is a spacious air fryer that offers the flexibility of two separate cooking zones or one large cooking area by removing the divider. The generous capacity and adaptable drawer design make it a practical option for preparing family meals.

There are a couple of practical drawbacks worth considering. The drawer is quite heavy, and I find it easiest to open using both hands. It also takes up a fair amount of kitchen space, and you need a large, clear surface to rest the drawer on when it is removed. A large chopping board or a suitable section of worktop can be useful.

On the plus side, I find the drawer easy to clean. I would also recommend considering air fryer liners, which are available from many retailers in different sizes and shapes. A suitable liner can help reduce food residue and make cleaning more convenient. Always check that the liner is suitable for the appliance and follow the manufacturer's instructions, including any guidance on safe use and airflow.

Not sponsored: I bought this air fryer myself at full price. This is not a sponsored post, and this review is genuinely my own.

My verdict: The Ninja Foodi FlexDrawer is a good option for people who want a large-capacity air fryer with flexible cooking options. However, its weight and footprint are important considerations, particularly if you have limited worktop space or prefer a lighter appliance.

What I like

  • ✓Generous 10.4L capacity.
  • ✓Flexible dual-zone and full-width cooking options.
  • ✓Easy-to-clean drawer.
  • ✓Suitable liners are available to help make cleaning more convenient.

What could be better

  • ✗The drawer is heavy and easier to handle with two hands.
  • ✗It takes up considerable kitchen worktop space.
  • ✗You need a suitably large surface to rest the drawer on when removed.

The key specs, in plain English

10.4L MegaZone or 2 × 5.2L zones
Take the divider out and you get one large drawer for a whole chicken, a joint or a big tray bake. Put it back and you have two independent zones. This flexibility is the reason to choose it over the AF400UK.
7 functions including Prove
Alongside air fry, roast, bake, reheat and dehydrate, the Prove setting holds a low, steady temperature for rising bread dough.
44 × 35 × 27cm, 9.1kg
It's big and heavy. Check your worktop depth and the height under your wall units, and plan to keep it out rather than moving it in and out of a cupboard.
"Up to 65% faster than a fan oven"
This is Ninja's own claim. Air fryers are generally quicker than ovens because they heat a smaller space and need little or no preheating, but actual time savings depend on the food.

Ninja Foodi FlexDrawer AF500UK: common questions

Can the Ninja FlexDrawer fit a whole chicken?

Yes. With the divider removed, the 10.4L MegaZone is designed to take a whole chicken or a joint.

Can I cook two things at different temperatures?

Yes, with the divider in place it works as two independent 5.2L zones, each with its own temperature and timer.

Is the FlexDrawer too big for a small kitchen?

It may be. At 44 × 35 × 27cm it's the largest Ninja here. If space is tight, the Double Stack XL gives you dual-zone cooking in a smaller footprint.

What guarantee does it come with?

The listing states a 2-year guarantee. Check the current terms, and whether you need to register the product, on Ninja's UK site.
