A solo microwave with manual power settings and a timer is a sensible starting point for warming custard; a grill or combi function is not needed for this task. A compact 20L model may suit a family serving dish if the dish can rotate freely, while a wider vessel calls for a closer look at turntable diameter and internal clearance rather than capacity alone. Follow the custard pack or recipe instructions, adjusting their timings for your microwave and retaining any stirring and standing stages.
If you warm several portions in one bowl or jug, check whether that particular vessel fits through the door and can turn without touching the cavity walls. The British Dietetic Association’s four-serving egg-custard recipe uses an approximately 20cm dish, but a handled serving vessel may need more room.
If controlling the warming process matters most, look for power and timer settings you can adjust between short stages. The British Dietetic Association’s egg-custard method and Ambrosia’s instructions for its ready-to-serve custard both call for stirring in their respective methods.
If the microwave will also handle leftovers but worktop room is limited, compare its external dimensions as well as its capacity. A compact model is useful only if your regular custard dish still fits with room to rotate.
Start with the dish you actually use, then assess how readily you can adjust power and time. Controls and cleaning matter most once the vessel fits.
| Concern | What to check | Who this matters to |
|---|---|---|
| Control over warming | Check the microwave’s output power, manual power settings and timer controls. Use the timing on your custard pack or recipe as the starting point. | If I want to stop and stir before custard gets too hot, I need controls that are easy to reset between stages. Around 42% of consumers would put this control first. |
| Serving-dish fit | Compare your vessel’s widest point, including handles, with the turntable, internal dimensions and door opening. Allow room for it to rotate. | For a family-sized jug or bowl, I need to know it will fit before choosing by cavity litres. For around 33% of consumers, vessel fit would be the primary concern. |
| Simple use and cleaning | Check whether the controls suit short manual runs and whether the turntable and cavity are practical to wipe after splashes. | When dessert preparation is busy, I would rather reset the microwave and clear up splashes without fuss. Around 25% of consumers would prioritise everyday operation and cleaning. |
The British Dietetic Association bases its microwave egg-custard recipe on an 800W appliance and says timings may need adjustment. Ambrosia likewise notes that microwave ovens vary in its ready-to-serve custard instructions.
Start with the directions for the exact custard, adjust them for your microwave and keep any instructed stirring or standing stages.
Capacity alone cannot tell you whether a wide bowl or handled jug will rotate. The British Dietetic Association’s approximately 20cm recipe dish and Panasonic’s 255mm turntable on the NN-ST22QBBPQ are useful measurements, not a fit guarantee for another vessel.
Measure the dish at its widest point, including handles, and check turntable size, cavity dimensions and door clearance.
Those cooking modes serve other tasks; warming custard calls for usable dish space and controllable microwave heating rather than grilling or baking.
Choose additional cooking modes only if you have a separate use for them.
Storage directions depend on the product. Ambrosia instructs purchasers of its Ready To Serve Light Devon Custard Can to remove leftovers from the opened can, refrigerate them and consume them within three days; that period does not apply to every custard.
Check the storage and reheating directions on the exact pack you are serving.
Panasonic lists both compact and larger solo models. Its NN-ST22QBBPQ is a 20L, 800W model with five power levels and a 255mm turntable; its NN-ST64QWBPQ is a 32L inverter model with a 34cm turntable.
Samsung describes the 23L MS23T5018AC as a solo microwave with a Ceramic Enamel interior that is easy to clean, a consideration if custard splashes.
The RHMD832T is listed as a 20L, 800W solo microwave with five heat levels, a 255mm turntable and dial/button controls.
These solo microwaves offer compact and roomier options for warming custard. Compare your serving vessel with each model’s usable space, then choose controls that suit the pack or recipe instructions you follow.

Consider this compact model if your serving vessel fits and you want manual control for staged warming.
20L capacity; 800W output; five power levels. Measure your bowl or jug, including handles, before relying on the stated capacity.
No image available
Consider the roomier format if you regularly use a wider family serving vessel, subject to checking that it fits and rotates.
25L capacity; 900W output. Adjust any custard instructions written for an 800W microwave rather than copying their timing unchanged.
No image available
This is a capacity option between the compact and larger models if it accommodates your usual serving dish.
23L capacity; 800W output. Check the final listing’s control layout if touch controls or dials matter to you, and confirm that your vessel can rotate freely.
No image available
Consider this model if a 23L solo microwave and its stated interior finish suit your routine for warming and cleaning up after dessert.
800W output; Ceramic Enamel interior. Check turntable diameter and timer controls against your dish and preferred reheating stages; the finish does not establish a custard-warming advantage.
No image available
Consider this compact manual model if its cavity accommodates your usual jug or bowl.
20L capacity; 700W output; MET Inverter Technology. Check the turntable diameter before ordering and adjust custard timings written for an 800W microwave.
No; a solo microwave with manual power settings and a timer can handle the warming task. Choose grill or combi functions if you also need those separate cooking modes, not as a substitute for checking dish fit and reheating controls.
It can fit some serving dishes, but capacity alone cannot confirm yours will fit. The British Dietetic Association’s four-serving egg-custard recipe uses an approximately 20cm dish; compare your vessel’s full width, including handles, with the chosen microwave’s turntable and internal clearance.
Follow the instructions on the exact pack. For Ambrosia Ready To Serve Light Devon Custard Can, Ambrosia specifies transferring the custard to a microwaveable container, covering it, heating for one minute, stirring, then covering and heating for a further minute in an 800W microwave. It says microwave timings vary; those steps are specific to that product.
Use a microwave-specific recipe and retain its stirring and standing stages. The British Dietetic Association’s egg-custard method is based on an 800W microwave, so adjust its timings for the appliance you use rather than treating them as universal.
