For a few portions of mushroom broth, start with a compact pressure cooker that fits your worktop while leaving room to handle the lid and inner pot. Consider a 5.7–6L model if you regularly make broth to store for later; guided controls and additional cooking modes matter only if you will use them enough to justify the space they take.
If you make a few portions at a time, bowl capacity is only part of the decision: the cooker also needs a workable place to stand. Instant Pot UK lists its Classic Mini at 3.8L, with dimensions of 31.8 × 35.1 × 25.6cm (depth × width × height).
If you make mushroom broth for several meals or to freeze, a larger bowl may be worth the worktop and storage space. Instant Pot UK lists a 5.7L Duo, while Tefal UK lists a 6L Cook4me+ with browning and simmering modes.
If selecting settings or handling steam is your main concern, guided controls may matter more than a compact body. Tefal UK describes on-screen guidance and automatic steam release on its 6L Cook4me Touch; its size still needs to suit your kitchen.
For mushroom broth, decide how much you normally make and where the cooker can stand before weighing guided controls or extra functions.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop fit and small batches | Compare the exact model’s depth, width and height with your available space; check its placement instructions as well as bowl capacity. | If I usually make just a few portions, I need room to use the cooker and lift out the pot safely. Around 36% of consumers put worktop fit and small batches first. |
| Broth for later meals | Check bowl capacity against your usual batch and compare the appliance’s external dimensions. | Making broth to refrigerate or freeze makes batch capacity more important than the smallest footprint; around 29% of consumers prioritise preparing several portions. |
| Controls and steam handling | Check whether the exact model has guided settings and automatic release, then read its pressure-release instructions. | If I am learning to use a pressure cooker, clear controls and less manual valve handling matter to me. Around 21% of consumers place that guidance first. |
| Other cooking tasks | Look for the modes you would use beyond broth, particularly sautéing or browning, and check cleaning instructions. | When one appliance needs to cover more of my cooking, I value functions I will use regularly; around 14% of consumers make broader use their primary concern. |
A bowl suited to freezer batches is of little help if the appliance cannot stand where you can use it safely. Bowl capacity does not tell you the cooker’s external dimensions.
Measure the intended worktop and storage location, allowing room to handle the hot lid and inner pot, and follow the exact model’s placement instructions.
Browning mushrooms in the same pot depends on the model’s functions. Without a suitable mode, you may need to change your method or use a separate pan.
Check the exact model’s sauté or browning mode and its removable-pot cleaning instructions before buying.
Automatic steam release does not remove the need to handle hot liquid and follow the cooker’s filling and lid instructions.
Before first use, read the exact model’s minimum-liquid, fill-level and pressure-release instructions. Do not force open a cooker that remains pressurised.
A UK Office for Product Safety and Standards report dated 18 August 2026 identified a serious fire risk linked to inadequate earthing in model MES6817. The finding concerns that model, not electric pressure cookers generally.
Choose a traceable seller, retain proof of purchase and check current safety alerts for the exact model you intend to buy.
Its Classic Mini and Duo lines offer different capacities for small batches and larger broth-making sessions.
Cook4me models are relevant if you want a 6L bowl alongside manual cooking modes or guided controls.
A larger multi-function option to consider if broth is only one of several tasks you want the appliance to handle.
These pressure cookers cover smaller broth batches and larger-batch cooking. Choose by your usual quantity and the space available, then check the exact model’s operating instructions.

Consider this 5.7L model if you make broth in larger batches and want to sauté ingredients in the same cooker.
The product name specifies pressure cooking, sautéing and a ceramic non-stick coating. Check its external dimensions, electrical compatibility and minimum-liquid instructions for your kitchen.
No image available
The 3.8L capacity is a starting point if you usually make smaller quantities of mushroom broth.
Compare this exact model’s dimensions with your worktop, and confirm its sauté function, electrical compatibility and minimum-liquid instructions before use.

Consider this 1.8L cooker only if its usable capacity suits your normal small batch.
Check its external dimensions and usable broth volume. If you want to brown mushrooms in the cooker, confirm that it has a suitable mode; also check its electrical rating and minimum-liquid instructions.

The 5.7L capacity is relevant if you intend to prepare several portions of broth rather than a small batch.
Measure the space available for this exact cooker. Check its sauté setting, suitable cooking instructions, electrical compatibility and minimum-liquid requirement before buying and use.
A compact capacity is a sensible starting point if you usually make only a few portions, provided the exact cooker fits your worktop and your recipe. Instant Pot UK describes its 3.8L Classic Mini as suitable for up to four portions; measure the appliance rather than choosing by litres alone.
No, but it lets you brown mushrooms or other ingredients in the same pot before adding liquid. Instant Pot UK lists sauté on the Classic Mini, and Tefal UK lists browning on the Cook4me+; check the function on the exact model you choose.
No: follow the minimum-liquid instructions for your exact cooker. The Instant Pot UK Duo manual says not to use that cooker without adding water and not to open it until its internal pressure has completely dropped.
Check the exact model’s electrical details, buy from a traceable seller and look for current product-safety alerts. A UK Office for Product Safety and Standards report dated 18 August 2026 identified a serious fire risk in model MES6817 specifically; it does not establish the same fault in other cookers.
Choose a larger multi-cooker if you will use its batch capacity or other modes regularly and it fits your kitchen. For scale, John Lewis & Partners lists the 7.5L Ninja Foodi MAX OL750UK at 39.1cm wide and 39.8cm deep; those dimensions are worth checking against a confined worktop before buying.
