The Ninja Foodi Max Pro AG651UK is a large-capacity health grill and air fryer designed to handle family-sized portions and more adventurous cooking. With a 3.78L basket, high 2460W power and temperatures up to 260°C, it aims to replace your grill, air fryer and even some oven jobs in one compact countertop appliance.
Ninja has a strong reputation in the UK for well-built, feature-packed small appliances, and this model fits that mould. It combines air frying, grilling, baking and more, with eight programmes and a built-in digital cooking probe to take the guesswork out of meat and fish.
With an excellent 4.8 out of 5 rating from over 400 owner reviews, it’s clearly a popular choice. It does sit at the premium end of the air fryer market, but on paper you’re getting more versatility and power than a basic basket fryer.
This model is best suited to medium and larger households that cook most days and want an air fryer that can genuinely take pressure off the main oven. The 3.78L capacity gives you enough room for generous portions of chips, chicken, sausages or veg, without having to cook in multiple batches for a typical family.
It’s a good fit if you’re trying to eat more healthily but don’t want to give up crispy, grilled-style food. The hot-air cooking and health grill design mean you can use little to no oil for everyday favourites, while still getting that browned finish you expect from a grill or frying pan.
If you like to mix things up in the kitchen, this is more than a simple “chips and nuggets” air fryer. With eight programmes, a flat plate and grill plate, baking capability and a digital probe, it suits confident home cooks and anyone who wants to experiment with steaks, roasts, and home-baked bread or desserts.
If you’re on a tight budget or only cooking for one, the size, power and price may be more than you really need. A smaller, simpler air fryer could make more sense if you just want occasional snacks and sides.
The generous 3.78L capacity is a real plus, giving you space for family meals, not just side portions. It’s large enough for big batches of chips or a decent-sized joint or whole chicken, which makes it a realistic oven alternative on busy evenings.
High power at 2460W and Ninja’s Cyclonic Air Technology allow the appliance to reach up to 260°C, so it heats quickly and delivers strong browning and crisping. That higher temperature range is especially useful for steaks, burgers and baked dishes where colour and texture matter.
The combination of health grill and air fryer functions, along with baking capability, means it’s genuinely versatile. The included grill plate, flat plate and ceramic-coated crisper basket give you different cooking options without needing separate gadgets on the worktop.
The digital cooking probe is a standout feature. Being able to set and monitor internal food temperature takes much of the guesswork out of meat and fish, helping you avoid undercooked centres or dried-out roasts.
Practical touches like dishwasher-safe components, non-slip feet and straightforward button and touch controls make it easier to live with day to day, and the strong user rating suggests reliability and consistent results.
The main drawback is that this is a premium-priced air fryer and grill. If you only want something for the odd portion of frozen chips, you may struggle to justify the extra spend over a simpler model.
It’s also quite a substantial appliance, with a footprint of roughly 44cm wide and nearly 40cm deep. You’ll need a decent amount of clear worktop space, and it’s not the sort of unit you’ll want to be constantly lifting in and out of cupboards.
At 0.94m, the power cord is on the shorter side, so you’ll need to position it fairly close to a socket, which may limit placement in some kitchens.
While the mixture of grill plate, flat plate, probe and basket adds versatility, it also means more bits to store and keep track of, and a slightly steeper learning curve if you’re moving up from a basic, single-basket fryer.
Day to day, the Ninja Foodi Max Pro AG651UK feels like a serious bit of kit. The controls combine buttons and touch input, so selecting one of the eight programmes and tweaking time or temperature is quick and intuitive. Once you’ve learned which plate or basket suits which style of cooking, getting meals underway is straightforward.
The generous cooking area means you’re not constantly shaking or rearranging food to get everything evenly cooked. Cyclonic air circulation does the heavy lifting, pushing hot air around the food so you don’t need to flip sausages or burgers midway through. That’s particularly handy when you’re juggling the rest of the meal.
Cleaning is less of a chore than you might expect for a grill-style appliance. The ceramic-coated crisper basket and the key components are dishwasher safe, which helps keep grease build-up under control. For quick turnarounds, a wipe down with hot soapy water is usually enough.
The shortish 0.94m cord means you’ll probably give it a semi-permanent home near a socket. Once in place, the built-in handles and non-slip feet make it feel secure and safe to move slightly when needed, without sliding around the worktop.
Noise levels aren’t specified, but as a powerful air-circulating appliance you should expect a noticeable fan sound while it’s running, similar to a strong extractor on a mid setting rather than a silent gadget.
With 2460W of power behind it, the Ninja Foodi Max Pro AG651UK gets up to temperature quickly and maintains heat well. The ability to reach up to 260°C is higher than many basic air fryers, which translates into better searing and crisper results on foods like steak, chicken wings and roast potatoes.
The 3.78L capacity is a strong point for performance. There’s enough room to spread food out so hot air can circulate properly, which helps with even cooking and avoids the soggy patch in the middle of an over-packed basket.
Ninja’s Cyclonic Air Technology is at the heart of how it cooks. Rather than relying on a static heat source, it circulates hot air around your food for consistent results without the need to keep turning or shaking. This is particularly helpful for busy households where you want to set the timer and focus on something else.
The eight cooking programmes and multiple accessories broaden what you can do. The grill plate is ideal for steaks, burgers and veg, while the flat plate suits foods like pancakes, eggs or delicate fish. The crisper basket covers classic air-fried favourites, and the baking function lets you tackle bread, pies, cakes and desserts without switching on the main oven.
The built-in digital cooking probe is a stand-out feature that you don’t see on many air fryers. It lets you monitor internal food temperature accurately, which is excellent for cooking joints, thick steaks or whole birds to a safe and juicy finish. Combined with the timer, it gives you much more control over doneness than simple time-and-guess cooking.
Added convenience features such as dishwasher-safe components and non-slip feet round out the package, making it not only powerful but also practical for regular, long-term use.
This is very much a premium air fryer and health grill, and its price reflects that. You can buy cheaper air fryers if all you need is a small basket for occasional chips or reheating leftovers.
Where the Ninja Foodi Max Pro AG651UK earns its keep is in the feature set and versatility. You’re effectively getting a high-heat grill, a large air fryer, a basic baking oven and a temperature-probe-guided roaster in one unit. For households that will use multiple functions several times a week, that consolidation can justify the extra outlay.
The 4.8/5 rating from a large number of owners suggests that real-world performance and reliability are strong, which adds to the sense of good long-term value. If you’re upgrading from a basic fryer and want something to genuinely change how you cook, rather than just add another gadget, the price starts to look reasonable.
If, however, your budget is tight or your usage will be light, a simpler and cheaper air fryer may offer better value for you personally.
The Ninja Foodi Max Pro AG651UK is an impressive all-rounder for anyone who wants more than a simple air fryer. With its large capacity, very high cooking temperatures, digital probe and mix of grill, air fry and baking functions, it’s capable of taking on a wide range of meals and doing them well.
It does demand a fair bit of worktop space and a higher budget than many entry-level models, and the extra accessories bring a slightly steeper learning curve. But if you cook for a family, enjoy grilled meats and roasted veg, or want to bake without always using the oven, it’s a compelling upgrade.
For committed home cooks and busy households looking to slim down cooking times and oil usage without sacrificing flavour, this is one of the stronger options in the category. If you only need a compact fryer for occasional snacks, you’ll be better served by a smaller, cheaper unit, but for serious, regular use the Ninja Foodi Max Pro is easy to recommend.
