For oxtail stew, choose an electric cooker with a pressure-cook function, a sauté setting and enough usable pot space for the oxtail, vegetables and liquid. A 5.6–5.7L multicooker is a practical starting point for household portions; consider a 7.5L model for larger batches, provided you have space for it and will use any additional functions.
If an all-day slow cook does not suit your schedule, look for pressure cooking and a sauté stage that lets you brown ingredients in the same pot. Allow time for the cooker to come up to pressure and release it afterwards; pressure cooking does not make the meal instant.
If you make stew for several meals, account for the space taken by bones, vegetables and liquid. Instant Pot UK describes its Duo 5.7L as a six-portion cooker, while SharkNinja UK lists 7.5L pots for its Foodi MAX OP500UK and OL750UK. In every case, the safe pressure-cooking fill limit is lower than the pot's stated capacity.
Choose controls you can follow confidently, and read the exact model manual before cooking. Lid fitting, required liquid, fill limits, valve care and pressure release all affect how you prepare and open the cooker.
Start with the functions needed for the stew, then check whether your usual batch fits within the pressure-cooking fill limit. Treat extra modes as useful only if they match meals you actually make.
| Concern | What to check | Who this matters to |
|---|---|---|
| Cooking schedule | Check for pressure cooking and a sauté setting, then follow the exact model's liquid and release instructions. | If I want tender oxtail without an all-day slow cook, I need a pressure stage and a way to brown the stew base in the pot. Around 42% of consumers put this cooking need first. |
| Usable batch space | Compare pot capacity with the manual's pressure-cooking fill limit; measure the appliance's external dimensions too. | When I cook enough stew for several meals, bones and vegetables need room alongside the liquid. For around 33% of consumers, batch space is the primary concern. |
| Controls and extra modes | Read the model's lid, valve and release instructions, and decide which additional cooking modes you would use. | If I am new to pressure cooking or want one appliance for other meals, I need controls I can follow and functions worth making room for. This is the leading concern for around 25% of consumers. |
Oxtail, vegetables and liquid take up space, but a pressure cooker cannot be filled to the brim. The litre figure describes total pot capacity, not the amount you can pressure-cook.
Check the exact model's fill guidance against your recipe. For the Instant Pot Duo, Instant Pot UK's manual sets a two-thirds maximum for most foods.
A larger pot may suit a bigger batch, but the appliance must also fit where you will use and store it. SharkNinja UK lists its 7.5L Foodi MAX models as substantial appliances.
Measure worktop space, overhead clearance and storage, then compare them with the dimensions and weight of the exact model.
Using the wrong lid procedure, too little liquid or an obstructed valve can create a risk of injury or appliance damage. Release controls and instructions differ between models.
Read the supplied manual, check the lid and valves as directed, and never force open a cooker that is still pressurised.
Electrical safety concerns can be specific to a product. In August 2026, the Office for Product Safety and Standards reported a serious fire risk from inadequate earthing in an Electric Pressure Cooker 6L; that finding does not apply to every cooker of that capacity.
Confirm the exact model and its intended market with the seller, and check official product-safety alerts for that model before buying.
Its Duo 5.7L is a reference point for a household-size pressure multicooker focused on stew rather than air frying.
Its 5.6L Express models combine pressure cooking with familiar slow-cooking and browning functions.
Its 7.5L Foodi MAX models are relevant when a larger stew batch or cooking modes beyond stew justify a bigger appliance.
These multicookers span a smaller 3.8L pot and two 5.7L options. Compare your stew batch with each model's pressure-cooking fill guidance before choosing by capacity alone.

Consider this for a household stew batch if its safe fill limit accommodates your usual quantity of oxtail, vegetables and liquid.
The product name specifies a 5.7L pot, sauté function, ceramic non-stick coating and recipe book. Confirm the exact model's electrical specification and consult its manual for liquid, filling and release instructions before use.

The 5.7L stated capacity makes this a model to assess for household-size stew batches; check how much your recipe can hold below its pressure-cooking fill limit.
Confirm the exact model identity, electrical specification and pressure-cooking instructions before purchase. The name identifies a 10-in-1 multicooker in black.

Consider the 3.8L pot for a smaller stew batch, but check that the oxtail, vegetables and liquid fit within its pressure-cooking limit.
The product name specifies a 7-in-1 multi-cooker in Sea Salt. Confirm the exact model's pressure-cook and sauté functions, electrical specification and manual instructions before relying on it for this recipe.
Prioritise pressure cooking and a sauté or sear/sauté setting, then check that the removable pot has enough usable space for your batch. Sautéing lets you brown ingredients in the pot before adding the liquid needed for pressure cooking.
No: stated capacity is the pot's total volume, not its safe pressure-cooking fill line. Instant Pot UK's Duo manual limits most foods to two-thirds capacity and foods that expand to one-half; follow the instructions for the exact cooker and recipe you use.
Yes, pressure cooking needs liquid to produce steam. Use the quantity and ingredient method specified for your cooker and recipe rather than transferring a generic amount between models.
Use the release method directed by the exact cooker manual and recipe, and wait until pressure has fully dropped before opening. Instant Pot UK's Duo manual also instructs users to check that valves are unobstructed before use; never force a pressurised lid open.
Confirm the exact model and its intended market with a traceable seller, then check official product-safety alerts for that model. For Great Britain, the Office for Product Safety and Standards sets out electrical-equipment safety requirements; its August 2026 fire-risk report concerns a specific Electric Pressure Cooker 6L with inadequate earthing, not all cookers of that size.
