How to Choose an Electric Multi-Cooker: A Practical Buying Guide

By Joybuy Product Recommendation OfficerPublished on: 2026-07-10

An electric multi cooker promises to be the ultimate kitchen shortcut: a single appliance that can pressure cook, slow cook, steam and more, saving you time, effort and washing up. For busy parents and professionals across the UK, it sounds like the perfect solution for getting a home-cooked meal on the table.

However, the market is flooded with models boasting endless functions and features. It's easy to choose a machine that either underwhelms or overwhelms, leading to it gathering dust in a cupboard. Before you invest, let's cut through the clutter and look at the common pitfalls that can lead to a disappointing purchase.

The 3 Traps to Avoid When Buying a Multi Cooker

1. The "More-is-More" Function Trap: A "9-in-1" or "14-in-1" cooker seems like incredible value, but how many of those functions are genuinely useful? Often, many presets are slight variations of a core function (e.g., multiple stew settings). You might be paying a premium for features you'll never use, while the core performance of pressure or slow cooking might be compromised.
2. The Vague Capacity Pitfall: A common point of confusion is the advertised capacity. A 5.7L electric cooker does not mean you can cook 5.7 litres of soup. For safety, especially when pressure cooking, you should never fill the pot more than two-thirds full (or half-full for foods that expand, like rice and beans). A 5.7L model has a realistic working capacity of around 3.8L, which is crucial to know if you're planning for family meals or batch cooking.
3. The Awkward Cleaning Flaw: The convenience of a one pot cooker is quickly undone if it's a nightmare to clean. Models with non-removable lids, complex seals that trap food particles or inner pots that aren't dishwasher-safe can add significant time and frustration to your post-dinner routine.

Decoding the Specifications: What Really Matters

To find the right all in one cooker, focus on the fundamentals that will impact your daily use. Here are the three core parameters to check.

1. Usable Capacity and Your Household Needs

Forget the marketing number for a moment and think in terms of portions.

• 2-3 Litres: Ideal for individuals or couples. These compact models are great for smaller kitchens and quick meals for one or two.
• 3.5-5.7 Litres: The sweet spot for most families of 3-5. A 5.7L electric cooker provides enough space for a whole chicken, a generous stew or batch-cooking portions for the week ahead.
• 6 Litres and Above: Suited for larger families or those who regularly entertain. These offer maximum capacity for big batches of chilli, soup or pulled pork.

2. Core Cooking Functions: Pressure, Slow and Sauté

A true electric multi cooker should master at least three key functions:

• Pressure Cooker: This is the main time-saver. It uses pressurised steam to cook food up to 70% faster than conventional methods. It's perfect for tenderising tough cuts of meat, cooking dried beans quickly and making stocks.
• Slow Cooker: For developing deep, rich flavours over several hours. This function is ideal for stews, curries and casseroles you can set in the morning and have ready by evening.
• Sauté: A vital function that allows you to brown meats and soften vegetables directly in the pot before pressure or slow cooking. This builds a crucial layer of flavour and means you don't have to use a separate frying pan.

Beyond these, functions like a rice cooker and steamer are highly practical additions that add to the appliance's versatility.

3. The Inner Pot: Material and Maintenance

The inner pot is where all the action happens. The two main types are stainless steel and non-stick.

• Stainless Steel: Highly durable, long-lasting and excellent for achieving a good sear on meats. It's completely inert and won't react with acidic foods. The downside is that food can stick, requiring more oil or careful technique.
• Non-Stick (Ceramic or Coated): Offers excellent food release, making both cooking and cleaning much easier. Look for coatings that are explicitly BPA-free, PFOA-free and PTFE-free for peace of mind. The main drawback is that these surfaces are less durable and can be damaged by metal utensils or abrasive cleaning.

Frequently Asked Questions

How much does it cost to run an electric multi cooker in the UK?

Electric multi cookers are generally more energy-efficient than using a conventional oven or multiple hob rings. A typical 1000W model running for one hour uses 1 kWh of electricity. Based on current energy prices, this often works out to be significantly cheaper per meal than running a 2-3 kWh oven for the same duration.

Can you leave a multi cooker on all day?

Yes, but only when using specific functions designed for long-duration cooking, such as 'Slow Cook' or 'Keep Warm'. These settings operate at a low, consistent temperature. You should never leave a multi cooker unattended during a pressure cooking cycle. Always refer to the manufacturer's safety instructions for your specific model.

Is a stainless steel or non-stick inner pot better?

This comes down to your cooking style and priorities.

• Choose stainless steel if you prioritise durability, high-heat searing and want a pot that will last for many years without worrying about scratching.
• Choose non-stick if your main priority is easy cleaning and cooking delicate foods like eggs or fish that are prone to sticking. A good quality ceramic non-stick pot offers a great balance of convenience and food safety.
