Buying a multi-cooker: how to compare features, capacity and safety

A multi-cooker can combine a rice cooker, slow cooker, steamer, electric cooking pot and pressure cooker in one appliance. This saves worktop space and can make it easier to prepare rice, soups, stews, pasta and steamed dishes. However, appliances vary considerably in their pressure functions, capacity, controls and ease of cleaning.

If you focus only on the number of programmes or advertised cooking times, you may end up with an appliance that isn’t right for your household. There are three common pitfalls to watch out for:

• More programmes don’t automatically mean more ways to cook. An electric multi-cooker with five programmes may not have a pressure function and may be better suited to cooking rice, steaming and slow cooking.
• The stated capacity isn’t the same as the usable fill level. With pressure cookers and foods that boil, you need to observe the maximum fill level.
• “Easy to clean” depends on which parts can be removed. The lid, sealing ring, steam outlet and inner pot should be cleanable as instructed in the manual. The main body must never be immersed in water.

What to look for when choosing a multi-cooker

1. Choose a capacity to suit your household

A compact multi-cooker with a capacity of around 1.8 to 2.3 litres may be enough for single people and students. For two to four people, appliances with a capacity of 3 to 4 litres are often more practical. Families and households that batch-cook may want to consider a model with a capacity of around 5 litres or more.

The litre capacity isn’t the only thing that matters. Check whether it refers to the full capacity of the inner pot or the recommended fill level. For soups, rice and pressure-cooking programmes, don’t exceed the marking inside the pot. This is also important with a multi-cooker with a steaming basket, as you’ll need extra room for water and steam.

2. Programmes and heating technology

A multi-function cooker can be designed with different priorities in mind:

• Pressure-cooking function: According to the manufacturer, this reduces the cooking time for certain dishes, but you’ll need to release the pressure safely and make sure the lid is closed properly.
• Slow cooker: Cooks at a low temperature over a longer period. Suitable for braised dishes, stews and soups.
• Rice cooker: Handy if you cook rice regularly and want to keep it warm afterwards.
• Steamer: Requires a suitable insert and enough water.
• Sautéing or searing: Not all appliances have the right heating power or coating for this.

Also consider how the controls work. Preset programmes, a timer and a keep-warm function are useful, but they don’t replace checking the fill level, cooking time and temperature.

3. Safety, materials and cleaning

An electric cooking pot should have overheat protection, a secure lid lock and controlled steam release if it operates under pressure. Steam can cause burns. Only open a pressure cooker once the pressure has fully released and the instruction manual says it’s safe to do so.

Always follow the manufacturer’s guidance on the coating. Use suitable kitchen utensils to avoid damaging a non-stick coating. Stainless steel inner pots are often dishwasher-safe, but should still be cleaned according to the instructions. For ceramic pots, check whether they’re intended for use only in the appliance. Never put a pot on a hob or naked flame unless the manufacturer expressly says it’s safe.

Frequently asked questions about multi-cookers

What size multi-cooker do I need for four people?

A capacity of around 4 to 6 litres is often a good choice for four people. What matters is the recommended fill level, not just the pot’s capacity. Leave extra room when cooking rice, pulses and pressure-cooked dishes.

How much electricity does an electric multi-cooker use?

Consumption depends on the power rating, cooking time and programme. A 700-watt appliance running at full power for an hour would theoretically use 0.7 kilowatt hours. In practice, the heating element switches on and off depending on the temperature control. To work out the running cost, multiply the energy used by your electricity tariff.

How long does a multi-cooker last?

Its lifespan depends on how often you use it, how you clean it and whether replacement parts are available. The sealing ring, non-stick coating, lid mechanism and steam outlet are particularly prone to wear. Before buying, check whether the manufacturer provides care instructions and suitable spare parts. Regular cleaning and following the fill-level and safety guidance can help reduce wear.
