The Best Large Air Fryer Oven for UK Families - Nyxi 35L Review
If you have ever wished your air fryer was bigger, smarter, and could do more than just chips - the Nyxi 35L Air Fryer Oven is exactly what you have been waiting for. This is not just a large air fryer. It is a full air fryer oven that bakes, roasts, grills, dehydrates, and air fries all in one big, beautiful machine.
Whether you are cooking for a big family, hosting friends, or you just want to stop using your main oven every single night, the Nyxi 35L is built to handle it all. With 35 litres of cooking space, dual French glass doors, and 12 cooking functions, this is the best air fryer oven for anyone who takes home cooking seriously.
Why a 35L Air Fryer Oven Changes Everything
Most air fryers on the market are 4 to 9 litres. That is fine for one or two people. But if you have a family, or you like cooking full meals in one go, a small air fryer just does not cut it. You end up cooking in batches, food goes cold, and you still need the oven anyway.
A large air fryer like the Nyxi 35L solves all of that. Here is what 35 litres actually means in real life:
Whole Chicken at Once
Cook a full-sized rotisserie chicken, no cutting needed. The 35L cavity fits birds up to 2.5kg with plenty of room to circulate hot air evenly.
Full-Size Pizza
Fit a 12-inch pizza flat, cook frozen or homemade. The wide shelves let you do two smaller pizzas side by side at the same time.
Family Meals in One Go
Cook your protein, veg and chips all at the same time on different racks. One press, one timer, everything done together.
Bake Like a Real Oven
Bake cakes, bread, muffins and pastries. The convection fan spreads heat so evenly that your bakes come out golden and perfectly risen.
Grill and Roast
The grill setting gets hot enough to give steaks and vegetables that proper charred, caramelised finish - just like an outdoor grill.
Dehydrate Snacks
Make dried mango, apple crisps, beef jerky and herb powders at home. The low-temperature dehydrate setting does the work slowly overnight.
12 Cooking Functions - One Machine Does It All
The Nyxi 35L Air Fryer Oven is not a one-trick machine. It has 12 preset cooking functions built right into the digital control panel. That means less thinking, less guessing, and perfectly cooked food every time.

How Does It Compare to a Normal Air Fryer?
A lot of people ask: is an air fryer oven really better than a standard air fryer? The answer depends on how you cook. But for most households, the difference is huge. Here is a simple side-by-side:
| Feature | Standard 9L Air Fryer | Nyxi 35L Air Fryer Oven |
|---|---|---|
| Capacity | 9 litres | 35 litres |
| Fit a whole chicken | No | Yes |
| See food while cooking | No | Dual French glass doors |
| Multiple racks at once | No | 3 rack levels |
| Baking function | Limited | Full bake mode |
| Rotisserie | No | Yes - included |
| Cooking functions | 4-6 | 12 |
| Replaces the oven? | Not really | Yes - for daily cooking |
The Dual French Glass Doors - A Game Changer
One thing most people notice straight away about the Nyxi 35L is those dual French glass doors. They are not just for looks. They make a real difference to how you cook.
With a standard basket air fryer, you have to pull the basket out every time you want to check your food. With the Nyxi 35L, you just look through the glass. No pulling, no heat escaping, no interrupting the cook. You can see exactly how your food is doing without touching anything.
The doors also open wide and flat, so loading and unloading is easy even with big trays and heavy joints of meat. There is no awkward basket to wrestle with.
Save Money on Your Energy Bills
One of the biggest reasons people switch to an air fryer oven is energy savings. A traditional full-size oven uses around 2,000 to 2,500 watts every hour. The Nyxi 35L uses significantly less power while cooking faster, because the smaller enclosed space heats up more quickly and holds temperature more efficiently.
For everyday cooking - weeknight dinners, quick lunches, batch cooking for the week - the Nyxi 35L can genuinely reduce your energy costs compared to firing up a full oven. Over a year, that adds up.
What Our Customers Say
"I was sceptical about spending this much on an air fryer oven but I am absolutely delighted. I cook for 5 people and this handles everything in one go. The rotisserie chicken was incredible - better than any takeaway. Best kitchen purchase I have made in years."
"As someone who loves baking, I was not sure an air fryer could replace my oven for cakes. It absolutely can. The heat distribution is perfect, everything comes out evenly baked. The 35 litre size means I can do two trays of biscuits at once. Very happy."
"I bought this as a big air fryer for my family and it has completely replaced our main oven for day-to-day cooking. The dual glass doors are so useful - I can see what is happening without opening it. Chips, roasts, even a birthday cake. This machine does it all."
