Space-first custard warmer
If you usually warm one small serving and have little worktop room, exterior dimensions, door clearance and room for your usual bowl matter more than extra cooking modes.
Who needs which microwave?
Gentle-reheat control seeker
If you prefer to warm custard in short stages, look for power settings and controls that make it practical to pause and stir rather than running one long cycle.
Small-kitchen all-rounder
If the microwave will also reheat ordinary meals, a compact 20L model may give your usual plates more room, provided it still fits the worktop.
What matters when choosing?
For a small kitchen where custard is the main task, check worktop and bowl fit before deciding how much control and meal-reheating room you need.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop and bowl fit | Measure the available space and allow for the model’s required ventilation and door clearance. Check that your bowl can rotate on the turntable. | With very little counter room, I need an appliance that fits without making my usual bowl awkward to use; around 42% of consumers would put space and bowl fit first. |
| Staged warming control | Check the available power settings and whether the timer and controls suit short heating stages. | I want to pause and stir custard instead of leaving it on one long cycle; roughly 33% of consumers would make warming control their primary concern. |
| Room for other meals | Compare cavity and turntable dimensions with the plates you regularly use, then check the appliance’s exterior depth. | If this microwave must also take my dinner plates, I need more usable dish space; about 25% of consumers would prioritise broader reheating capacity. |
Mistakes to avoid
-
Choosing by litres alone
A 17L or 20L capacity does not tell you whether the microwave fits your counter or whether your bowl can turn freely inside it.
Compare exterior and cavity dimensions, turntable diameter and the exact model’s ventilation and door-opening requirements before ordering.
-
Running one long high-power cycle
Microwaved food can be hot at the edges while remaining cooler in the centre. Food Standards Agency reheating guidance says stirring helps prevent this uneven heating.
Use a microwave-safe bowl, warm custard in short stages at a lower setting where available, stir between stages and follow any pack instructions.
-
Choosing combi modes for custard alone
Grill, convection and air-fry modes serve different cooking tasks; they do not replace the need for suitable bowl space and controlled reheating when warming custard.
Start with solo microwaves, and consider additional modes only if you expect to use them for other cooking.
Microwave brands to consider
Russell Hobbs
The RHMM701R is a compact 17L solo model for comparing space-first options. It has a 700W output and a 24.5cm turntable.
- Its dial controls and five power levels offer a manual-control option.
- Check that your usual bowl and plates fit the 17L cavity and rotate freely.
Cookworks
The 700W Standard Microwave is another 17L solo example. Its exterior size is H24.3 × W44.6 × D32.3cm and its turntable 24.5cm.
- Those stated dimensions give you a concrete footprint to compare with your worktop.
- Allow for the model’s required clearance, and check that your bowl fits the turntable.
Panasonic
The NN-ST23QMBPQ illustrates a compact 20L solo route. It has an 800W maximum output and a 25.5cm turntable.
- Its stated turntable is larger than those of the 17L examples above, which may matter for your regular plates.
- Check the exterior fit; extra capacity does not remove the need to stir custard during staged heating.
Haden
The Haden Starbeck is a 20L manual-control example listed with 800W output, six power levels and dual dials.
- Its removable 24.5cm turntable provides a dish-size reference for this 20L option.
- Joybuy marks this particular Starbeck listing as unavailable; treat it as a feature comparison rather than a current purchase option.

Questions about warming custard
What type of microwave do I need to warm custard?
A countertop solo microwave is sufficient for the basic task. Choose one with a turntable that fits your bowl and controls you can use for short heating stages; consider grill or convection modes only if you need them for other cooking.
How can I reduce uneven heating when microwaving custard?
Warm it in a microwave-safe bowl in short stages, stirring between them and following any pack instructions. Food Standards Agency reheating guidance notes that microwaved food can be hot at the edges while still cold in the centre.
Do I need a 20L microwave just for custard?
Not necessarily: a 17L model may suit an individual bowl if it fits and rotates freely. Consider 20L when you also need space for your regular plates, and check the appliance’s exterior dimensions before choosing.
Can I reheat leftover custard more than once?
Avoid reheating leftover custard repeatedly. GOV.UK food-hygiene guidance for businesses advises reheating food until it is steaming hot throughout and reheating it only once; safe storage and thorough reheating still matter whichever microwave you use.
