Ninja Foodi MAX 15-in-1 SmartLid Multi-Cooker OL750UK with Digital Cooking Probe (7.5L)

The essentials

If you want one counter appliance that can pressure cook, air fry and slow cook without having to juggle multiple lids and functions, the Ninja Foodi MAX OL750UK is built around that idea. It’s a 7.5L electric multi-cooker with a SmartLid system, designed to handle a wide range of cooking styles in one pot.

On paper, the appeal is the combination of 15 cooking functions and a digital cooking probe that’s meant to take the guesswork out of doneness. It also targets batch cooking for up to 6 portions, so it’s not really aimed at tiny meals or single-serve cooking.

The one thing to keep in mind: a multi-cooker with lots of programmes can be great, but you’ll still get the best results when you follow the guide and give yourself time to learn which functions suit which foods.

What it is and what it’s for

This is an electric pressure cooker and air fryer with additional cooking modes. Depending on the programme you select, it can pressure cook, slow cook, air fry and also do more “oven-style” tasks like bake and grill.

A practical example: imagine you’ve planned a roast dinner but want crisp edges without babysitting the oven. You could use pressure cooking for tender results, then finish with an air-fry style approach (via the available air fry-related functions) to help with texture. For steaming meals, it’s also set up for modes that cook with steam, which can be useful if you’re trying to keep certain foods from drying out.

Where it stands out in day-to-day use

The headline feature is the integrated Digital Cooking Probe. The basic promise here is straightforward: it monitors food temperature as it cooks and lets you know when it’s ready to remove, with less guessing.

That matters most if you cook proteins regularly (roasts, chicken portions, thicker cuts) where doneness is less forgiving than, say, baking. Having a probe-controlled approach can also reduce the “wait and check” routine, especially when you’re cooking for a full table.

There’s also a claim around energy saving: it says you can save up to 60% on your energy bill (based on testing/calculations comparing air fry use versus conventional ovens for a specific example). It’s a useful statement, but it’s worth viewing it as conditional on how you actually cook, what you cook, and your typical cook times.

Functions you actually get (15 in total)

This model is positioned as the kind of machine that covers a lot of dinner options in one go. The 15 functions listed include: - Pressure Cook - Air Fry - Grill - Bake - Dehydrate - Prove - Sear/Sauté - Steam - Slow Cook - Yoghurt - Steam Meals - Steam Air Fry - Steam Bake - Steam Bread - Steam Roast

With that range, you’re not just buying a pressure cooker or an air fryer—you’re buying a “choose your method” appliance. The flip side is that you may not use every programme, and that’s normal, the real value tends to come from the functions you repeat.

Capacity and portion planning

Ninja states it cooks up to 6 portions. It also mentions fitting a 3kg roast or 1.8kg of French fries, which gives you a sense of scale.

The 2-tier rack and related capabilities are designed so you can layer ingredients for complete multi-part meals in one pot. If you often cook mains and sides together, that two-tier approach can be genuinely handy—though it’ll depend on your recipes and how well the timing matches up.

Worth noting: as with any multi-layer cooking setup, you’ll want to choose ingredients that finish around the same time. Otherwise, you may end up splitting tasks between programmes.

Tech notes that affect buying decisions

This is the Ninja Foodi Max 7.5L multi-cooker (stainless steel/black colour), model OL750UK.

Key practical specs provided include the dimensions (H36cm x W35cm x D36cm) and a 2-year guarantee upon registration with Ninja (UK & ROI only). It also ships with a 7.5L cooking pot, the 4.7L cook & crisp basket, a 2-tier rack and a digital cooking probe, plus a chef-created recipe guide.

Who it suits, and who should pause

It’s a good fit if you: You cook for more than one person regularly, want pressure cooking plus air frying in the same machine, and like the idea of using a temperature probe to help hit doneness with less checking.

It may not suit you if: You’re after a simple pressure cooker or a basic air fryer only, and you don’t want to spend time deciding between 15 programmes. Also, if your main meals are small and you mainly care about speed for one-two portions, the bigger capacity may be more appliance than you need.

Buying verdict

Is it worth it?

The Ninja Foodi MAX OL750UK makes a lot of sense if you’re looking for a versatile electric cooker that can cover pressure cooking, air frying and slow cooking from one base, and you’ll actually use the wide programme list. The Digital Cooking Probe is a standout addition because it’s aimed at reducing guesswork around temperature and readiness.

However, it’s not automatically the best choice if you want something ultra-simple or purely focused on one cooking style. With a multi-function machine, the value depends heavily on whether you’ll run repeat recipes and learn which modes you trust.

Before you commit, check whether the 7.5L capacity and the multi-tier meal approach match how you cook week to week. Also consider whether probe-based cooking is your kind of convenience, rather than feeling like a feature you might ignore.
