Weeknight split-pea-soup cooks
You want a shorter cooking schedule for dried split peas and a sauté stage for the soup base in the same pot. A pressure-capable model offers that route, provided you follow its liquid, lid and fill instructions.
Who these multicookers suit
Slow-cook soup planners
You can allow several hours for gentle cooking and may want enough soup for more than one serving. Slow-cook mode matters more to you than having a pressure-cooking option.
One-appliance kitchen consolidators
You make soup but also expect to use other cooking modes. Check whether air frying or crisping would earn its place alongside the appliance’s size, weight and storage requirements.
What matters when choosing
Start with your cooking schedule: Sage Appliances UK describes pressure cooking as a faster method than slow cooking’s low, steady heat over several hours. Then check the functions, usable batch size and space requirements of the exact model.
| Concern | What to check | Who this matters to |
|---|---|---|
| Shorter, one-pot cooking | Look for Pressure Cook and Sear/Sauté. Read the model’s instructions for liquid, pressure fill and release. | If I need split pea soup on a shorter schedule, I want to sauté the base without moving it to another pan. Around 45% of consumers put that faster, one-pot route first. |
| Slow cooking and batch size | Check Slow Cook, nominal capacity and the usable fill level for your intended recipe. | When I can plan several hours ahead, I care more about making enough soup for the servings I need. That is the primary concern for around 33% of consumers. |
| Other functions and space | Compare the additional modes you would use with the appliance’s dimensions, weight and included accessories. | I want one appliance for soup and other meals, but it still needs to fit where I will use or store it. Roughly 22% of consumers prioritise that balance. |
Buying pitfalls
-
Treating the stated capacity as the pressure-cooking fill level
The litre figure describes the pot’s nominal capacity, not necessarily how much split pea soup it can hold under pressure. Instant Pot’s instructions set fill limits, including a lower limit for expanding foods in its Duo Easy manual.
Before choosing a batch size, read the manual for your exact cooker and follow the fill rule that applies to the ingredients you are using. Do not exceed the marked limit to make a larger batch.
-
Choosing crisping functions for a soup-only routine
Pressure cooking, slow cooking and sautéing address the main split-pea-soup tasks. Extra modes affect what else an appliance can do, while the space needed varies by model: SharkNinja UK lists its crisping-capable Ninja OP350UK at 13.3 kg and 55.3 cm long.
If soup is your regular use, compare models with the cooking modes you need before choosing one with an additional crisping lid.
-
Following a pressure recipe without checking the cooker’s instructions
Pressure cooking requires the appropriate liquid, fill level and lid operation. Instant Pot UK instructs users of its Plus 5.7L model to add a water-based liquid when pressure cooking.
Use the recipe alongside the manual for your exact model and capacity, including its sealing and pressure-release directions. Do not assume that instructions for a different cooker or lid also apply.
-
Assuming electrical-safety details are interchangeable
In August 2026, the Office for Product Safety and Standards reported a serious fire risk for a specific electric pressure cooker identified as Electric Pressure Cooker 6L, citing its fuse and plug pins. That report does not describe pressure cookers as a category.
Check the identity and documentation of the model you intend to buy, and consult current product-safety alerts for that model before purchase.
Relevant brands to consider
These product lines illustrate different combinations of soup-relevant functions and capacities; a brand name alone does not establish the features or suitability of every model.
Instant Pot
Its UK multicooker range includes pressure, slow-cook and sauté options relevant to split pea soup, including 5.7L and 8L models.
- Instant Pot UK lists the 5.7L Classic with pressure cooking, slow cooking and sautéing; it presents the 8L Duo as an option for larger batches.
- Nominal capacity is not the usable pressure-cooking fill level. Follow the instructions for the particular model and ingredients.
Ninja
Ninja’s UK range includes multicookers with pressure and slow cooking, as well as Foodi models with additional air-fry and crisping modes.
- SharkNinja UK lists Pressure Cook, Slow Cook and Sear/Sauté on the 6L PC201UK; the OP350UK adds modes including air frying and grilling.
- The OP350UK’s listed weight of 13.3 kg and length of 55.3 cm are worth checking against your available space if its extra modes appeal to you.
ProCook
ProCook offers a 4.5L multicooker combining pressure cooking, slow cooking and air frying.
- ProCook lists eight cooking settings, including pressure cooking, slow cooking and air frying, for its 4.5L model.
- Compare the 4.5L pot and its applicable fill instructions with the amount of soup you intend to make rather than assuming it will accommodate a larger batch.

Frequently asked questions
Do I need a dedicated soup programme for split pea soup?
No dedicated soup button is necessary if the multicooker has a cooking mode suited to your recipe. Look for sautéing if you want to cook the base in the pot, pressure cooking for a shorter schedule, or slow cooking when you can allow several hours; check the exact model’s instructions for the mode you use.
Can I fill the pot to its stated capacity when pressure cooking split peas?
No: use the applicable pressure-fill limit in your exact model’s manual, not its nominal litre capacity. Instant Pot UK’s Duo Easy manual specifies a half-full maximum for expanding foods such as dried vegetables, while its Plus 5.7L guidance also sets a pressure-fill mark. Follow your own model’s rule for the ingredients in your soup.
What electrical-safety checks matter when buying in Great Britain?
Identify the exact model, check its GB-market documentation and look for any current safety alert affecting it. The Office for Product Safety and Standards reported a serious fire risk involving the fuse and plug pins of a specific Electric Pressure Cooker 6L in August 2026; that finding should not be generalised to every multicooker.
What should I check after cooking split pea soup?
Follow the cleaning and inspection steps in your model’s manual, particularly for parts involved in sealing and collecting condensation. Instant Pot UK’s Plus guidance includes cleaning and drying the inner pot and emptying the condensation collector; do not assume that lids or cleaning instructions are interchangeable between models.
