Weeknight one-pot cooks
If you want to sauté the ragout base and then pressure-cook the lentils in one appliance, look for both functions and controls you are comfortable using.
Who these cookers suit
Batch-cooking households
If you make extra portions for later meals or freezing, compare the bowl size with the model’s pressure-cooking fill limit and the space it needs in your kitchen.
Multifunction-appliance shoppers
If you also plan to steam, slow-cook or air-fry, consider those modes alongside the extra lids or cleaning tasks they may bring. They are not necessary just to make lentil ragout.
What matters when choosing
Start with the portions you intend to cook, then decide whether simple controls or additional cooking modes matter more to you.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portions and leftovers | Compare bowl size, appliance dimensions and the exact model’s pressure-cooking fill limits. | If I cook enough ragout for later meals, I need a bowl that accommodates the batch without exceeding its fill mark. Around 36% of consumers put batch capacity first. |
| Controls and one-pot cooking | Check for pressure cooking, a sauté mode if needed, and timing and keep-warm controls that suit your routine. | When I want to prepare the base and cook the lentils in one appliance, straightforward controls matter more to me than extra modes. Around 36% of consumers prioritise that ease of cooking. |
| Extra modes and cleaning | Consider which additional functions you will use, how many lids need storing and the care instructions for removable parts. | If I will use the cooker for other dishes too, I want the added functions to justify the storage and washing involved. Around 28% of consumers put versatility or clean-up first. |
Buying pitfalls
-
Treating bowl capacity as usable cooking capacity
A nominal 8L bowl cannot be filled to the top for pressure cooking. Fill limits vary by model and can be lower for ingredients that expand.
Compare the portions you need with the exact cooker’s manual and interior fill markings, rather than choosing by litres alone.
-
Choosing extra functions you will not use
For lentil ragout, a separate air-frying lid adds a storage and cleaning task without being required for the pressure-cooked dish.
Consider a model with that lid if you also expect to use its crisping or roasting functions.
-
Judging electrical suitability by a listing’s appearance
An August 2026 Office for Product Safety and Standards report identified a serious fire risk involving an underweight fuse in one electric pressure cooker. A listing’s appearance alone cannot establish the suitability of the appliance supplied.
Before ordering, check the intended market, plug, voltage, seller or importer details, supplied documentation and any current product-safety alerts.
-
Following instructions for a different cooker
Lid fit, valve checks, fill limits and pressure-release steps depend on the model. Instructions for another cooker may not apply to yours.
Use the compatible lid and follow the manual supplied for the exact model when making lentil ragout.
Brands to consider
Instant Pot
Instant Pot UK documents Duo electric pressure cookers in 5.7L and 8L sizes, offering different starting points for one-pot meals and larger batches.
- The documented Duo 5.7L combines pressure cooking and sautéing; Instant Pot UK also lists a dishwasher-safe stainless-steel pot and lid for that model.
- The documented Duo 8L weighs 7.2kg and needs more room, so check where it will sit and be stored.
Tefal
Tefal UK documents a 4.8L Turbo Cuisine with a single dial and a 7.6L Turbo Cuisine & Fry with an additional air-frying lid.
- Tefal lists 10 programmes, delayed start and keep-warm capability for the 4.8L Turbo Cuisine.
- The 7.6L Turbo Cuisine & Fry has two detachable lids; consider their storage and cleaning needs if ragout is your main reason for buying.

COSORI 5.7L 9-in-1 electric pressure multi-cooker
Consider this model if you want to sauté the base of a larger ragout before pressure cooking in the same appliance.
The product name specifies a 5.7L bowl, sauté and other cooking functions, and a ceramic non-stick coating. Check the model’s pressure-cooking fill instructions, plug and voltage before choosing it.

Instant Pot Pro 10-in-1 5.7L multicooker, black
The 5.7L size is worth considering if you regularly make several portions of ragout rather than a small meal.
Confirm the exact model’s sauté controls, pressure-cooking fill limit and pot-care instructions, as well as the supplied plug and voltage. Care details for the Duo 5.7L should not be assumed to apply to this Pro model.

ochama Mini Green Pot 1.8L electric pressure cooker
Consider this smaller cooker for modest portions rather than large batches of ragout.
Its product name specifies a 1.8L capacity. If you want to brown aromatics in the same pot, check for a sauté mode; also check the model’s fill instructions and electrical details before use.
Common questions
What size pressure cooker should I choose for lentil ragout?
Choose by the portions and leftovers you intend to make, not the stated litres alone. Tefal UK documents a 4.8L Turbo Cuisine, while Instant Pot UK describes its Duo 5.7L as a six-portion model and its Duo 8L as an eight-portion model; check the fill limits for the particular cooker you choose.
Can I fill the bowl to the top for a bigger batch?
No: follow the pressure-cooking fill limit in your exact model’s manual. The Instant Pot Duo Plus manual sets a two-thirds maximum and a one-half maximum for foods such as rice or dehydrated vegetables that expand; do not apply those figures to another model without checking its instructions.
Do I need an air-frying lid to make lentil ragout?
No: pressure cooking and, if you want a one-pot workflow, sautéing are the functions to look for. An air-frying lid is worth considering if you will also use it for crisping or roasting; Tefal UK documents two detachable lids on its Turbo Cuisine & Fry 7.6L.
What should I check about an electric cooker sold for use in Great Britain?
Check the intended market, plug, voltage, responsible seller or importer and supplied instructions, rather than relying on a marking alone. Office for Product Safety and Standards guidance dated March 2025 explains that the Electrical Equipment (Safety) Regulations 2016 apply to electrical equipment placed on the Great Britain market; Northern Ireland has different provisions, so check the applicable local guidance if buying there.
How do I use the pressure cooker safely for ragout?
Read the exact model’s manual before cooking and follow its directions for liquid, fill level, lid, valves and pressure release. The Instant Pot Duo Plus manual warns against opening the cooker while it is under pressure or pressure cooking without water; use the instructions for your own model rather than assuming its procedures are identical.
