Choose an electric pressure cooker by the space your bones, vegetables and liquid will need below its maximum-fill marking, not by nominal capacity alone. A 5.7L cooker may suit your dinner-party batch if everything fits within its instructions; a 7.5L vessel offers more nominal room, but its usable stock yield still depends on the model’s filling guidance.
You need room for chicken bones, vegetables and liquid without exceeding the cooker’s fill marking. Check the quantity your menu requires against the exact model’s instructions rather than treating its stated litres or portion claim as finished stock yield.
You want to make stock while preparing other dishes. Check that the cooker has a pressure-cooking function and that its controls and release instructions fit the way you plan to cook.
You expect to use the appliance after the dinner party for tasks such as sautéing, slow cooking or steaming. Compare the exact model’s functions, pot material, cleaning instructions and warranty rather than relying on its function count.
Work out the stock quantity and filling limit first. Then decide which pressure-cooking controls and uses beyond stock-making matter to you.
| Concern | What to check | Who this matters to |
|---|---|---|
| Practical batch capacity | Compare vessel capacity with the exact model’s maximum-fill marking; allow space for bones, vegetables and liquid. Sage Appliances advises filling to no more than two-thirds capacity for most foods. | I need enough stock for my guests without crowding the cooker past its fill limit; around 42% of consumers put practical batch capacity first. |
| Timing and control | Confirm pressure cooking is available and read the model’s instructions for its controls and pressure release. | When I am preparing other dishes, I want a cooking process I can plan around; roughly 33% of consumers prioritise timing and control. |
| Cleaning and further use | Check which parts are dishwasher-safe and whether you will use functions beyond pressure cooking. | I want an appliance I can clean and use for other meals after the party; about 25% of consumers put those ongoing uses first. |
A 5.7L or 7.5L label describes vessel capacity, not how much finished chicken stock a pressure cooker can hold. Bones and vegetables take up space, and the fill limit still applies.
Estimate the ingredients and liquid your batch needs, then check the exact cooker’s fill marking and manual before choosing a size.
COSORI describes a 5.7L, 14-in-1 cooker on its UK product page, while a Joybuy listing describes a 5.7L, 9-in-1 COSORI cooker with a ceramic non-stick pot. Shared brand and capacity do not establish that they are the same model.
Compare the full model identifier, functions, supplied pot and applicable warranty for the listing you intend to buy.
Making stock ahead of a dinner party also means planning what happens after pressure cooking, particularly if it will not be served immediately.
Decide in advance whether you will serve the stock straight away, refrigerate it or freeze it, and follow appropriate food-handling guidance.
A longer programme list does not tell you whether the cooker has the batch space or controls you need for chicken stock.
Prioritise pressure cooking, the practical fill limit, release instructions and cleaning. Consider extra functions only if you expect to use them for other meals.
Instant Pot UK describes its Classic 5.7L as a seven-function electric pressure cooker and states that it can make up to six portions.
Ninja UK describes the Foodi MAX OP500UK as a 7.5L, nine-function multi-cooker with pressure cooking.
COSORI UK lists a 5.7L, 14-in-1 electric pressure cooker with a steam-release button and dishwasher-safe parts.
Drew & Cole lists Pressure King Pro pressure cookers in 3L, 5.7L and 6L sizes.
This 5.7L pressure multi-cooker is a choice to consider if your planned chicken-stock ingredients fit within its own filling instructions and you want functions for other meals.

Consider this cooker for stock if the bones, vegetables and liquid for your batch fit below the exact model’s maximum-fill marking.
The listing describes a 5.7L vessel, pressure cooking, a ceramic non-stick pot and functions including steaming, slow cooking and sautéing. Check the manual, UK electrical suitability and warranty for this exact variant before buying; do not assume the specifications of COSORI’s separately listed 14-in-1 model apply.
It can be, provided your planned bones, vegetables and liquid fit below that model’s maximum-fill marking. Instant Pot UK describes its Classic 5.7L as making up to six portions, but that claim is not a measure of finished stock volume; check your recipe quantity against the cooker’s instructions.
Follow the exact appliance manual for the lid, sealing ring, valve, required liquid, fill limit and pressure release before the first batch. For example, Instant Pot UK instructs owners of its Plus 5.7L model to perform a pressure-cooking test run before first use; follow the instructions for your own model rather than applying that model’s procedure to another cooker.
No. An automatic cooking programme does not replace planning how stock will be served, cooled and stored. If you are making it ahead, decide how you will refrigerate or freeze it and follow appropriate food-handling guidance.
No; check the warranty for the exact model and seller. Instant Pot UK lists a one-year guarantee for the cited Classic 5.7L, while COSORI UK lists a two-year warranty for its cited 5.7L 14-in-1 cooker. Those terms should not be assumed to apply to a different variant.
