Start with a 5.7–6L electric pressure multi-cooker for a typical family meal, then check its fill rules before deciding how much chicken and barley soup you can make. Consider a larger vessel for regular batches and leftovers, or guided controls if you would rather follow on-screen prompts; either choice still calls for enough worktop space and a manageable pressure-release process.
If one cook needs to cover dinner and perhaps leftovers, compare the usable fill level with your recipe quantity. The vessel’s litre rating alone will not tell you how much soup you can pressure-cook, and a larger appliance also needs somewhere to sit and be stored.
If you want to brown ingredients before cooking the soup under pressure, look for both sauté or browning controls and a pressure-cook mode. Instant Pot and Tefal list these functions on the models discussed here.
If choosing settings and releasing pressure feels unfamiliar, clear instructions may matter more than a long list of modes. Tefal describes its Cook4me+ as offering step-by-step guidance and automatic pressure release; you should still follow the instructions for the exact model.
Decide how much soup you need to cook within the permitted fill level, then choose controls you are comfortable using. Treat functions unrelated to soup as a separate decision.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable soup capacity | Compare the exact model’s fill rules and dimensions with your planned batch; do not use its nominal litre rating as the permitted soup volume. | If dinner needs to stretch to leftovers, I need room for chicken, stock and expanding barley without exceeding the fill limit. Around 42% of consumers put batch capacity first. |
| Controls and pressure release | Check for pressure cooking, browning or sautéing, clear model instructions and a release procedure you can follow. | When I am new to pressure cooking, I want guidance through the cooking stages and a release process I understand. For around 33% of consumers, that reassurance is the primary concern. |
| Everyday versatility | Confirm the modes you would use beyond this soup and how the inner pot should be cleaned. | If the cooker will also handle other regular meals, I care whether its additional modes earn their place in the kitchen. Broader one-pot use comes first for around 25% of consumers. |
A pressure cooker cannot necessarily be filled to the rim. The Instant Pot Duo manual limits general filling to two-thirds of capacity and gives a one-half limit for foods that expand, including rice and dehydrated vegetables.
Plan the chicken and barley soup against the fill marks, manual and liquid requirements of the model you intend to buy. Consider a larger cooker only if the permitted batch size justifies its footprint.
Guided programmes can help with settings, but they do not establish that the chicken in your particular soup is cooked through. The Food Standards Agency’s household food-safety guidance identifies cooking food until it is steaming hot and cooked all the way through as an important practice.
Handle raw chicken hygienically, follow a suitable recipe and check that it is thoroughly cooked before serving.
Air frying or grilling does not replace the need for suitable pressure controls, usable capacity and a release process you understand. Which? assesses pressure cookers for cooking, ease of use and steam release rather than judging them by function count alone.
Confirm pressure cooking and browning or sautéing first. Choose other modes if they match meals you expect to make regularly.
Electrical equipment sold for Great Britain is subject to applicable product-safety requirements. UK government guidance recognises CE marking alongside or instead of UKCA marking in relevant circumstances; a marking alone is not a substitute for checking the appliance’s identity and instructions.
Confirm the exact model, its manual and the applicable product documentation with the seller. If delivery is to Northern Ireland, check the requirements for that destination rather than relying on Great Britain guidance.
The Duo range combines pressure cooking and sautéing with other cooking modes. Instant Pot describes its 5.7L Duo as a six-portion model and its 8L Duo as an eight-portion model.
The Cook4me+ CY851840 is a 6L guided pressure cooker that Tefal describes as making up to six servings. It offers on-screen recipe guidance as well as manual cooking modes.
These electric pressure multi-cookers offer two vessel sizes for a family soup meal: a 5.7L option and a 7.1L option for those planning a larger batch. Check each model’s permitted fill level against your recipe before choosing by size.

Consider this 5.7L model if you want to sauté ingredients and pressure-cook a family soup in one appliance.
Its listed functions include pressure cooking, sautéing, steaming and slow cooking; the product name also specifies a ceramic non-stick coating and recipe book. Check the model’s fill instructions against the chicken and barley recipe, and confirm its dimensions if worktop space is tight.
No image available
Consider this 7.1L model if you regularly plan larger family soup batches and want to sauté before pressure cooking.
Its product name specifies seven functions, while the product information identifies pressure cooking and sautéing among them. Check the exact model’s fill instructions, dimensions and inner-pot cleaning guidance before deciding whether the larger vessel suits your kitchen.
Start by comparing 5.7–6L models for a typical family meal: Instant Pot calls its 5.7L Duo a six-portion model, and Tefal describes its 6L Cook4me+ as making up to six servings. If you regularly need a larger batch or leftovers, consider a larger vessel, but use its permitted fill level rather than its nominal capacity to plan the recipe.
No: leave the headroom required by your exact model’s instructions. The Instant Pot Duo manual sets a two-thirds general maximum and a one-half maximum for foods that expand, such as rice or dehydrated vegetables; check your cooker’s guidance when planning a recipe containing barley.
No: a programme or timer does not replace checking that the chicken is thoroughly cooked. Follow a suitable recipe, handle raw chicken hygienically and make sure the food is steaming hot and cooked all the way through before serving, in line with the Food Standards Agency’s food-safety guidance.
No: for chicken and barley soup, start with pressure cooking, browning or sautéing, usable capacity and a release procedure you can follow. Choose extra modes if you expect to use them for other meals; Which? also considers ease of use and steam release when assessing pressure cookers.
Yes: check the documentation applicable to the exact appliance and its delivery region. For Great Britain, UK government guidance recognises CE marking alongside or instead of UKCA marking where the relevant regulatory requirements allow it, and electrical equipment must meet applicable safety requirements. For delivery to Northern Ireland, confirm the appropriate documentation with the seller rather than applying Great Britain guidance automatically.
