Choose a multicooker around the amount of broth you need in one batch, checking the exact model’s maximum-fill instructions rather than treating its stated capacity as usable pressure-cooking volume. An 8L pressure model offers more batch room than a 5.7–6L model, but its size needs to work in your kitchen; a slow-cooking model suits a longer cooking window when pressure cooking is not a priority. If you are making broth ahead, plan how you will cool and refrigerate it promptly.
Who needs which approach?
Hosts making one large batch
You need enough room for the planned broth, not just a large capacity figure on the appliance. Instant Pot’s Duo instructions limit pressure-cooking fill to two-thirds of the pot, so check the recipe volume against the model’s instructions before relying on a single batch.
Hosts cooking on the day
Pressure cooking may fit a tighter schedule, but leave time for the cooker to come to pressure and release it safely. Check those steps alongside the cooking programme when planning the rest of the meal.
Buyers who prefer guided controls
If an occasional dinner party makes unfamiliar pressure controls feel daunting, compare the instructions and on-screen guidance. Tefal presents its Cook4me range around step-by-step recipes and automatic pressure release; the cooker’s safety instructions still apply.
What matters when choosing?
8L pressure multicooker
Choose when: A large single pressure-cooked batch matters most. Instant Pot UK describes its Duo 8L as suitable for up to eight people.
Allow for: The Duo’s pressure-fill limit and the space needed for an 8L appliance.
5.7–6L pressure multicooker
Choose when: The planned portions fit a smaller pot or guided operation is important. Instant Pot UK and Tefal UK each describe relevant models as serving up to six.
Allow for: Less single-batch room than an 8L pot, particularly once the applicable pressure-fill limit is considered.
Non-pressure slow or simmer cooker
Choose when: You can give the broth a longer cooking window and do not need pressure cooking. The Ninja Possible Cooker MC1001UK, in the product information, has slow-cook and simmer functions.
Allow for: This route does not meet a plan that depends on pressure cooking; check the exact model’s functions and liquid-fill instructions.
| Concern |
What to check |
Who this matters to |
| Usable batch size |
Match guest portions and recipe volume to the exact model’s fill marking. Instant Pot’s Duo manual limits pressure-cooking fill to two-thirds. |
I want to serve the planned amount of broth without needing another batch; around 36% of consumers would put usable batch size first. |
| Same-day timing |
Confirm the cooker has a pressure programme if your schedule depends on one, and allow for pressurising and safe release. |
When broth has to fit around preparing the other dishes, I need a workable cooking schedule. Roughly 29% of consumers would make timing their primary concern. |
| Controls and release |
Compare the exact model’s controls, lid and pressure-release instructions; check whether guided recipes or manual modes suit you. |
I will use pressure cooking more confidently if I can follow the settings and release steps clearly; for about 21% of consumers, that guidance would matter most. |
| Uses beyond broth |
Choose additional functions only for meals you intend to make; check for the slow-cook, sauté or simmer modes your broth plan requires. |
If this cooker will also handle other meals, I care about functions I will use after the party. Around 14% of consumers would put broader cooking use first. |
Buying and planning pitfalls
-
Planning a pressure-cooked batch from the headline capacity
A pot’s stated litres are not its permitted pressure-cooking fill. The Instant Pot Duo manual limits filling to two-thirds, or one-half for foods that expand.
Check your recipe volume against the fill instructions for the exact cooker and cooking mode before deciding whether one batch will suffice.
-
Choosing extra functions solely for broth
Air-frying, grilling and baking are separate uses; their presence does not establish that a multicooker will make better vegetable broth.
Decide which cooking method you want for broth, then consider specialist functions only if you expect to use them for other meals.
-
Overlooking the space an 8L cooker needs
Instant Pot UK lists the Duo 8L at 37.6 × 33.8 × 36.1 cm and 7.2 kg. A larger batch capacity is useful only if you have a practical place to use and store the appliance.
Measure the intended worktop and storage space, and follow the cooker’s instructions for safe placement and steam release.
-
Cooling a make-ahead batch in one large pot
A large quantity of hot broth needs a cooling and storage plan. GOV.UK’s home-food guidance says to cool cooked food and put it in the fridge within one to two hours.
Divide the broth into suitable smaller containers to help it cool, and make room in the fridge before you start cooking.
Relevant brands to consider
Instant Pot
The Duo pressure-multicooker range offers 5.7L and 8L routes for different planned batch sizes.
- Instant Pot UK describes the Duo 5.7L as feeding up to six people and the Duo 8L as feeding up to eight.
- The Duo manual’s maximum-fill instructions limit usable pressure-cooking volume; check the dimensions of the model you intend to store.
Tefal
The Cook4me+ CY851840 is a 6L pressure multicooker for buyers interested in screen-led cooking.
- Tefal UK states a capacity of up to six servings and describes step-by-step on-screen recipes for the Cook4me range.
- A 6L stated capacity offers less pot volume than an 8L option; guided controls are not evidence of better broth.
Ninja
Its cited multicookers cover different methods: the 7.5L Foodi MAX OL750UK includes pressure cooking, while the 8L Possible Cooker MC1001UK offers a slow-and-simmer route.
- Ninja UK lists pressure cooking and slow cooking among the OL750UK’s functions;the product information lists slow cooking and simmering for the MC1001UK.
- Check the particular model rather than assuming both offer pressure cooking, or that additional air-fry and grill functions are useful for broth.

Questions about broth and multicookers
What capacity do I need for dinner-party vegetable broth?
Choose capacity from your guest count, serving size and the permitted fill level for your cooking method. Instant Pot UK describes its Duo 5.7L as feeding up to six people and its Duo 8L as feeding up to eight, while Tefal UK describes the 6L Cook4me+ as serving up to six. Those are starting points for planning, not guaranteed broth yields: the Instant Pot Duo manual limits pressure-cooking fill to two-thirds.
Do I need pressure cooking to make vegetable broth?
No; a slow-cooking or simmering model can suit broth when you have time for a longer cook. Choose a pressure-capable model if pressure cooking is important to your schedule, and include pressurising and safe release in that schedule. The product information lists slow-cook and simmer functions for the Ninja Possible Cooker MC1001UK.
Can I make the broth ahead of the dinner party?
Yes, provided you plan to cool and refrigerate it promptly. GOV.UK’s home-food guidance says to cool cooked food and place it in the fridge within one to two hours; dividing a large batch into smaller portions helps it cool faster.
What should I check before pressure-cooking broth?
Follow the instructions for the exact cooker’s lid, fill level and pressure release. The Instant Pot Duo manual says not to fill its pot beyond two-thirds of capacity and applies a stricter one-half limit to foods that expand. Do not force open a pressurised lid.
