If your oven is always crammed or you’re trying to cut down on energy bills and cooking oil, a dual zone air fryer can feel like discovering a second kitchen. The Ninja MAX 6-in-1 Dual Zone DZ400UK Air Fryer is one of the most talked-about models in the UK right now, with thousands of positive ratings, and it’s helped make air frying an everyday habit rather than a weekend gadget.
This guide walks through what living with a dual zone air fryer is really like, how to choose the right size and features, and practical tips to get the best results. If you’d like a deep dive into this specific model, including specs and real-world testing, you can always read our full review of the Ninja MAX 6-in-1 Dual Zone DZ400UK Air Fryer.
Why dual zone air fryers have become everyday essentials
Air fryers started out as a way to make chips with less oil, but dual zone models have turned them into serious oven alternatives. Instead of one big basket, you get two separate drawers, each with its own temperature and timer. That means chicken in one, chips in the other, or veggie sides cooked to perfection while your main crisps up beside them.
The Ninja MAX 6-in-1 Dual Zone DZ400UK sits in this sweet spot: big enough for family cooking, flexible enough for smaller meals, and packed with multiple cooking modes. For many households, it ends up replacing the oven on weeknights, handling everything from frozen food to full roast-style dinners.
Getting to know the Ninja MAX 6-in-1 Dual Zone DZ400UK
The DZ400UK is part of a popular range of dual zone air fryers and has earned a standout reputation, helped by its excellent user rating of 4.9 out of 5 from more than 4,500 reviews. While the precise capacity and technical details are covered in depth in our dedicated write-up, it’s designed with generous drawers and a footprint that suits most standard UK kitchens.
As the name suggests, it offers six cooking functions. While the exact labels vary by model, you can expect the usual mix of air fry, roast, reheat and related modes, all aimed at letting you cook a wide range of meals without switching appliances. Dual controls on the front make it easy to set time and temperature separately for each side, and a sync-style feature helps you get everything ready at once.
If you’re wondering how all of that translates into actual performance and noise levels, it’s worth taking a look at our hands-on experience in more detail. You can read our full review of the Ninja MAX Dual Zone DZ400UK here for cooking tests, pros and niggles.
Is a large dual zone air fryer right for your kitchen?
Before you fall in love with the idea of cooking your whole Sunday dinner in drawers, it’s worth checking that a larger dual zone model fits your space and lifestyle. Here are the main questions to ask.
1. How many people are you cooking for?
If you regularly cook for three or more people, a machine like the DZ400UK makes a lot of sense. Having two drawers lets you cook enough chips or potatoes on one side and a good amount of chicken, fish or meat on the other. It’s also ideal if you cook different meals for kids and adults, or have a mix of meat-eaters and vegetarians who don’t want everything cooked together.
For couples or solo cooks, the DZ400UK still works well because you can simply use one drawer most of the time. The second drawer then becomes a bonus for batch cooking or hosting guests.
2. Do you have enough counter and cupboard space?
Any dual zone air fryer has a larger footprint than a compact single-basket model. Before buying, clear a space and measure it, including clearance above for steam and ventilation. Think about access to nearby sockets and whether you’ll leave it out permanently or store it away between uses.
Most people find that once a dual zone fryer is on the counter, it rarely goes back in the cupboard, simply because it ends up being used so often. If you’re very tight on space, you might prefer a smaller single-drawer model instead, though you’ll lose the flexibility of cooking two elements at once.
3. What do you actually cook during the week?
It’s easy to get excited about recipes, but think about your real routine. If your weeknights are heavy on frozen chips, nuggets and fish fingers, a dual zone fryer will blast through those in less time and with less oil than the oven. If you enjoy more involved cooking, you can roast veg in one drawer while searing or roasting protein on the other.
The Ninja MAX 6-in-1 is particularly handy if you like experimenting: it’s flexible enough to handle everything from breakfast items to baked treats. Over time, many owners end up using the oven far less often, particularly for small or medium-sized meals.
What can you cook in a dual zone air fryer?
Once you move past the obvious chips and frozen bits, dual zone air fryers open up a lot of options. Here are some meal ideas that work brilliantly with a model like the DZ400UK.
- Quick after-work dinners: Chicken goujons or fish fillets in one drawer; chips or wedges in the other. Most meals like this take under 25 minutes, including preheat.
- Healthier midweek meals: Salmon fillets or chicken breasts in one drawer, mixed veg like broccoli, peppers and onions in the other, with just a drizzle of oil.
- Fakeaway nights: Chips and onion rings in one, spiced chicken or tofu strips in the other, served in wraps or bowls.
- Breakfast and brunch: Hash browns in one drawer, sausages or veggie sausages in the other, while eggs and beans bubble away on the hob.
- Batch cooking: Roast extra potatoes or veg in one drawer while you cook that night’s main in the other, then cool and store for easy lunches.
The key is to think in pairs: mains and sides, kids’ meals and adult meals, or tonight’s dinner and tomorrow’s packed lunches.
Tips for getting the best results from the Ninja MAX DZ400UK
Whichever dual zone air fryer you choose, a few simple habits can transform your results from “not bad” to consistently excellent. The Ninja MAX 6-in-1 Dual Zone DZ400UK is forgiving, but these tips will help you get the most from it.
Don’t overfill the drawers
Air fryers work by moving hot air around your food. If the drawers are crammed full, the air can’t circulate properly and you’ll end up with half-crisp, half-soggy food. Try to keep food in a single, even layer whenever possible, or at least no more than two layers deep for smaller items like chips.
Use a light touch with oil
One of the biggest advantages over a traditional deep fat fryer is how little oil you need. A quick spray or a teaspoon of oil tossed through chips or veg is usually enough to get a golden finish. Many frozen foods don’t need any extra oil at all, as they already have some in the coating.
Shake or turn halfway through
For small items like chips, wedges and nuggets, take a moment to pull the drawer out halfway and give everything a shake. For larger pieces, flip or turn them once. This helps them crisp evenly and avoids pale patches where food has been resting against the crisper plate.
Match foods and timings
When using both drawers at once, try to pair foods that cook in roughly similar times, or use the controls to stagger them. For example, you might start potato wedges a bit earlier on one side, then add salmon fillets to the other drawer later. The independent controls on the DZ400UK make this easy once you get used to it.
Energy efficiency: can an air fryer really save money?
One of the big selling points of air fryers is energy efficiency. Instead of heating a large oven cavity for a relatively small amount of food, you’re only heating the space inside the drawers. This generally means faster preheating, shorter cooking times and less wasted heat.
In a typical week, the biggest savings tend to come from quick meals and reheating. Heating a full-sized oven just to rewarm leftovers for one or two people can cost more than using a dual zone air fryer. Over time, especially if you cook from fresh regularly, those small differences can add up on your energy bills.
Cleaning and maintenance: keeping your air fryer fresh
Cleaning is one of those chores that can make or break how often you use any kitchen gadget. Happily, modern dual zone air fryers are designed to be easy to maintain, and the Ninja MAX 6-in-1 Dual Zone DZ400UK is no exception.
Daily cleaning routine
Once the drawers have fully cooled, remove them and take out the crisper plates or racks. Wash them in warm, soapy water using a soft sponge to protect the non-stick coating. If your model allows it, you can also pop them in the dishwasher, but always check the manual first.
Give the inside of the unit a gentle wipe with a damp cloth to remove crumbs and splashes, being careful around the heating element. Wipe the exterior with a soft cloth to keep it looking smart on the counter.
Deep cleaning and odour control
Every few weeks, do a more thorough clean. Soak the drawers and crisper plates to loosen any baked-on residue, and gently scrub around any awkward corners. For lingering food smells, you can run the air fryer empty for a few minutes at a moderate temperature after cleaning, which helps burn off remaining odours.
A little care goes a long way: well-maintained drawers will stay non-stick and easier to clean, and the cooking results stay consistent.
Is a dual zone air fryer better than a single-drawer model?
Whether dual zone is “better” comes down to how you cook. Dual zone machines like the Ninja MAX DZ400UK are brilliant for multitasking, cooking mains and sides together, and managing different dietary needs in one go. They’re ideal for families, busy couples and anyone who cooks varied meals during the week.
Single-drawer models tend to be more compact and can be cheaper, making them a good fit for smaller kitchens or very simple cooking routines. If you rarely cook more than one thing at a time, a single basket might suit you perfectly. But if you’re fed up with juggling oven shelves or timing chips and chicken separately, dual zone is a major upgrade.
How to get started with your first week of air frying
If you’re new to air frying, the first week or two is about building confidence. Here’s a simple progression that works well with a dual zone model like the DZ400UK.
- Day 1–2: Frozen favourites – Start with chips, wedges and frozen breaded items, using the suggested times in the manual as a guide and adjusting to taste.
- Day 3–4: Simple fresh dishes – Try fresh chicken breasts or thighs, salmon fillets or sausages alongside vegetables, learning how your machine browns and cooks through.
- Day 5–6: Mixed meals – Use both drawers at once for a full meal: for example, seasoned chicken in one drawer and Mediterranean veg in the other.
- Day 7: Leftovers and reheating – Reheat pizza slices, roast potatoes or pastry-based snacks; most people are surprised how much better the texture is compared with a microwave.
By the end of the first week, you’ll have a good feel for timings and can start tweaking temperatures and experimenting with homemade recipes.
When a different air fryer might suit you better
The Ninja MAX 6-in-1 Dual Zone DZ400UK is a strong all-rounder for families and keen home cooks, but it isn’t the only approach to healthier, faster frying. If you discover that you don’t have the counter space, or your budget is tighter, you might look at more compact or single-drawer alternatives across the wider market.
Think carefully about capacity, controls you’ll actually use, and how often you’ll cook two separate elements at once. Dual zone isn’t essential for everyone, and there are very capable single-basket machines that offer excellent performance if you usually cook one-pot style meals or simple sides.
Final thoughts: choosing with confidence
A good air fryer can genuinely change how you cook on busy days, and a dual zone model like the Ninja MAX 6-in-1 Dual Zone DZ400UK pushes that even further by letting you cook full meals, not just sides. With impressive user feedback and a flexible 6-in-1 design, it’s an appealing choice for households that want faster, simpler and often healthier cooking.
