The best air fryer for a family of 3 or more in 2026
Two drawers, seven cooking functions, and the Match Cook setting that actually works. Deservedly the UK’s best-selling air fryer.
Our verdict
After six weeks and 60 real-world family meals, the Ninja AF400UK has earned its spot at the top of our air fryer rankings. The dual-drawer design is the feature that makes it: you can roast chicken thighs in one zone while crisping chips in the other, and the Match Cook button finishes both at the same time regardless of how long each item needs.
It is not cheap at around £199-249 on Amazon UK, and it takes up significant counter space. But for a family of 3 or more, this is the single kitchen appliance that changes how you cook on a weeknight. Chips from raw potatoes in 18 minutes, no oil. Chicken breasts in 14. We now use our oven maybe twice a week instead of daily.

Who should buy the Ninja AF400UK?
The AF400UK is the right air fryer for households of 3 or more, and for anyone who wants to cook two different foods at the same time. The dual-zone design doubles effective capacity and lets you match finish times. For a solo user or a couple, a single-drawer Ninja AF160UK or Tower T17129 is plenty and saves £80-100.
Avoid if you have a small kitchen with less than 50cm of clear counter space. This appliance is large and tall, and it needs clearance above for steam venting.
What it actually cooks well
Frozen chips: 16 minutes at 200°C for a proper Maris Piper crunch. Chicken thighs: 22 minutes at 190°C, skin turns to crackling. Roast potatoes from raw: 28 minutes with Match Cook syncing to whatever else you are doing. Salmon fillets: 10 minutes at 180°C with skin intact.
Where it underperforms: anything that needs steam or braising (the dehydrate function is slow and noisy for this), and cakes/bakes that need even surround heat (a normal oven is better).
Running costs at UK electricity rates
At 2400W running for 20 minutes, the AF400UK uses 0.8 kWh. At the UK average of 28p/kWh, that is 22p per cook. A typical fan oven uses about 2.1 kWh for the same job (equivalent to 59p per cook). Over 300 cooks a year you save roughly £110.
The initial cost of the AF400UK pays back in electricity savings in under two years for a family that previously ran the oven daily.

Both drawers and crisper plates are top-rack dishwasher safe. In practice we handwash the crisper plates (food residue sticks in the dishwasher sometimes) and dishwash the drawers.
The main unit wipes clean with a damp cloth. After six weeks there is no smell, no discolouration and no cooking residue on the exterior. Build quality is solid.
Noise and kitchen practicality
On standard Air Fry mode: 58dB at 1 metre, similar to a quiet extractor fan. On Max Crisp: 65dB, noticeable but not disruptive to conversation.
Smell is better than an oven for most foods, because the sealed drawers contain splatter. Fish, bacon and strong spices do still scent the room but clear quickly with an open window.
Ninja AF400UK vs alternatives
Against the Tower Vortx Eclipse T17129 (~£129), the Ninja has more power, better crisping, and the dual-zone Match Cook feature. Tower wins on price and footprint.
Against the Ninja AF451UK (the newer 10.4L version), the AF400UK is a sensible 1-2 litres smaller but normally £40-60 cheaper. The newer model adds ClearView windows, which some cooks find useful.
Against the Cosori Pro LE 4.7L (~£89, single zone), the Ninja is the upgrade pick. Cosori is fine for 1-2 people; for families the single drawer limits you.
Frequently asked questions
Does the Ninja AF400UK cook two different foods at once?
Yes. Each drawer has independent temperature and time controls, so you can cook chicken at 190°C in one drawer and chips at 220°C in the other. The Match Cook and Sync buttons make the timings line up so everything is ready together.
Is it dishwasher safe?
The drawers and crisper plates are top-rack dishwasher safe. The main unit is not and should never be submerged; wipe the exterior with a damp cloth only.
How big is the Ninja AF400UK?
9.5L total, split across two 4.75L drawers. External dimensions 41.5 × 27 × 32 cm. You will need about 50cm of clear counter width plus 10cm of air gap above for venting.
Can it replace my oven?
For most everyday cooking, yes. Chicken, chips, potatoes, fish, vegetables, bacon and reheating all work better and faster in the air fryer. Cakes, breads and large joints still need a conventional oven.
What is the difference between Air Fry and Max Crisp?
Air Fry runs up to 200°C with standard fan speed. Max Crisp runs up to 240°C with maximum fan speed for extra browning and crunch. Use Max Crisp for the last 2-3 minutes to crisp up frozen chips, wings and breaded items.
Does it use a lot of electricity?
At 2400W for a typical 20-minute cook, it uses about 0.8 kWh or 22p at current UK rates. That is roughly 60% less than doing the same cook in a fan oven, so it is cheaper to run despite the high wattage.
