Family meal preppers
If onions are part of a larger vegetable-prep job, you may want enough working capacity to avoid repeated batches. A chopping blade and a way to stop and inspect the cut matter too.
Who might need one?
Small-kitchen cooks
If cupboard or worktop space is limited, a compact processor may be easier to accommodate. Check its working capacity against the amount you usually prepare: Kenwood GB, for example, lists a 1.3L bowl but a 0.75L working capacity for the MultiPro Go FDP23.140GR.
Small-quantity cooks
If you often chop one onion or a small flavour base, a dedicated smaller bowl may be more relevant than a large main bowl. Magimix Support says its mini bowl is designed for small amounts of onion and herbs.
What matters when choosing?
Decide how much you normally chop at once, then weigh texture control against the space and cleaning involved in using the processor regularly.
| Concern | What to check | Who this matters to |
|---|---|---|
| Working capacity | Compare usable or working capacity with the onions and other vegetables you prepare together, not just the bowl’s total size. | If I chop onions with other vegetables for a family meal, I want to limit repeat batches. Around 36% of consumers put working capacity first. |
| Chop texture | Look for a chopping blade and pulse or moment control on the exact model; stop and inspect between short pulses. | When I need visible onion pieces rather than an overly fine chop, I want to control when processing stops; around 29% of consumers prioritise texture control. |
| Storage and cleaning | Check the appliance dimensions, accessory storage and exactly which removable parts are dishwasher-safe. | For everyday onion prep, I need a machine I can store and clean without making the job cumbersome. Storage and clean-up come first for around 21% of consumers. |
| Small portions | If one onion is a frequent task, confirm whether a mini bowl or another suitable small-quantity arrangement is supplied. | I often prepare just one onion or a little herb-and-onion mixture, so a small-portion setup matters more to me than maximum bowl size; around 14% of consumers make that their primary concern. |
What is easy to overlook?

Confusing bowl size with working capacity
Kenwood GB lists a 1.3L bowl and a 0.75L working capacity for the MultiPro Go FDP23.140GR. A larger number on the bowl specification does not necessarily describe the amount you can prepare in one batch.
Check the exact model’s usable or working capacity against the onions and accompanying ingredients you normally chop.
-
Assuming a large bowl suits a single onion
A large main bowl is not automatically the most convenient arrangement for a small portion. Magimix Support describes its mini bowl as designed for small amounts of onion and herbs.
If small portions are common in your kitchen, check whether a mini bowl is included or the manufacturer describes another suitable arrangement.
-
Choosing on wattage alone
Motor power does not tell you the working capacity, whether a chopping blade and pulse setting are present, or which parts need washing after use.
Compare those features on the exact model before using wattage to distinguish your options.
-
Skipping cleaning and recall checks
Equipment used for raw and ready-to-eat foods needs appropriate cross-contamination controls. Recalls also apply to specific products: Electrical Safety First identifies a recalled Kenwood julienne disc affecting FPM800 and FPM810 units manufactured from January 2019 to December 2021, not every Kenwood processor.
Follow the manufacturer’s cleaning instructions, keep raw-food preparation separate where relevant, and check any recall against the exact model and production information.
Brands to consider
Kenwood
Kenwood’s cited models span a compact processor and a larger multi-function option.
- Kenwood GB lists in-bowl storage and a 0.75L working capacity for the compact MultiPro Go FDP23.140GR; the MultiPro Express FDP65.860WH has a stated 3L bowl and pulse control.
- Those capacity figures describe different models and are not interchangeable batch-size measures. Check the working capacity of whichever model you choose.
Bosch
The MultiTalent 3 MCM3201BGB is a mid-size example for household vegetable prep.
- Bosch GB lists 2.3L usable volume, two speeds, a moment function and dishwasher-safe accessories for the MCM3201BGB.
- Capacity, controls and supplied accessories vary by model; the MCM3201BGB specifications should not be assumed for other Bosch processors.
Magimix
A multi-bowl setup is worth considering when small onion portions alternate with broader family prep.
- Magimix Support says its mini bowl is designed for small amounts of onion and herbs; Magimix UK positions the 3200XL for up to four people.
- Separate bowls mean additional parts to handle and store. Check the bowls and accessories included with the exact configuration.

Common questions
What size processor makes sense for onions in a family meal?
Choose by the quantity you prepare together, using working capacity where it is stated. For perspective, Kenwood GB lists a 0.75L working capacity for the compact MultiPro Go FDP23.140GR, while Bosch GB lists 2.3L usable volume for the MCM3201BGB. A larger bowl may reduce batching when onions accompany other vegetables, but bowl size alone does not establish a suitable batch size.
How do I keep chopped onions from becoming too fine?
Use a chopping blade with pulse or moment control, stopping after short bursts to inspect the pieces. Bosch GB describes pulse use for chunkier textures, while Kenwood GB lists pulse control for the FDP65.860WH; the result will still depend on how much you load and how long you process it.
Will a large processor work well for just one onion?
Do not assume the large main bowl is the most convenient setup for a small portion. If one onion is a frequent job, check for a supplied mini bowl or another manufacturer-supported small-quantity arrangement; Magimix Support describes its mini bowl as designed for small amounts of onion and herbs.
What cleaning and recall checks matter?
Follow the manufacturer’s cleaning instructions and take care to avoid cross-contamination if the equipment is also used for raw and ready-to-eat foods, a concern identified in Food Standards Agency hygiene guidance. For an older or second-hand processor, check recall notices against its exact details: Electrical Safety First identifies a Kenwood julienne-disc recall affecting FPM800 and FPM810 units manufactured from January 2019 to December 2021.
