For warming custard, prioritise microwave power settings and controls that let you heat in short intervals; you will still need to stir and check it before serving. For batch-cooked food, measure your usual containers against the usable cavity and turntable arrangement rather than choosing by litre capacity alone. Choose a combination model for its oven, grill or air-fry functions only if those modes will earn their place in your cooking routine.
If you usually warm small or medium portions, adjustable microwave power and short heating intervals matter more than oven-style functions. Panasonic lists seven power levels for its NN-CT56RB; whichever model you choose, use suitable cookware and check the food as you heat it.
If you use casserole dishes or rectangular containers, check the usable interior, turntable diameter and any turntable-off instructions. A capacity figure alone cannot tell you whether your usual dish will fit.
If you also expect to bake, grill or air fry, a combination microwave may serve more of your routine. Consider the appliance’s space requirements alongside the modes you will actually use.
Start with how you will warm custard, then check your largest regular container. Treat additional cooking modes as a separate decision: they need to suit meals you plan to make.
| Concern | What to check | Who this matters to |
|---|---|---|
| Controllable reheating | Look for adjustable microwave power and controls that make short intervals straightforward. Do not treat wattage or inverter claims as a substitute for stirring. | When I warm custard or sauce, I want to adjust the heating and stop before it gets too hot. Around 36% of consumers put controllable reheating first. |
| Container fit | Measure your dish and lid, then compare them with the usable interior, turntable diameter and any turntable-off guidance. | A casserole or rectangular batch container needs to fit in the way I intend to use it, not merely match a stated capacity. Container fit comes first for roughly 36% of consumers. |
| Additional cooking modes | Check which convection, grill or air-fry modes you would use, plus the appliance’s installation and space requirements. | If I regularly cook more than reheated portions, I want the extra modes to justify the space they occupy. Around 28% of consumers prioritise that versatility. |
A lidded casserole may not fit or rotate even when the cavity sounds spacious. Sharp lists a 36.2cm turntable for the 40L R959SLMA, while Samsung describes a turntable-off option for larger square-shaped dishes on the separate MC28A5135CK model.
Measure the dish’s width and height, including its lid, and check the exact model’s usable interior and operating instructions.
Panasonic describes its inverter technology as supporting even reheating, but that manufacturer claim does not guarantee that custard will heat uniformly.
Use an appropriate microwave setting, heat in short intervals, stir well and check before serving.
Electrical Safety First warns that unsuitable containers can cause problems in microwave mode. A container suitable for microwaving should not automatically be assumed suitable for grill or convection temperatures.
Use clearly microwave-safe cookware for microwave heating, and consult the model manual before using a container or lid in another mode.
Electrical Safety First advises against powering a microwave through an extension lead. A large model may also need a particular electrical arrangement: Sharp lists a 16A distribution-line fuse or circuit-breaker requirement for the R959SLMA.
Check the exact model’s installation instructions and your available socket or circuit before buying. If replacing an appliance, confirm the retailer’s take-back and collection arrangements.
GOV.UK guidance distinguishes free in-store take-back of qualifying electrical waste from home collection, for which transport costs may be charged.
The NN-CT56RB is a 27L option for shoppers interested in adjustable microwave heating alongside convection, grill and air-fry modes.
The R959SLMA offers a 40L cavity for shoppers assessing larger dishes as well as microwave, grill and convection cooking.
The MC28A5135CK is a 28L combination model worth considering when the shape of your cookware matters.
These multi-function microwaves offer different starting points for reheating portions and cooking other meals, including one built-in model. Check the controls, usable dish space and cooking modes of the exact model you are considering.

Consider this model if you want to warm portions and also have an air-fry mode. Its title lists a 23L capacity, 900W and a 1000W grill; check how its microwave-only controls work and whether your batch dish fits.

This is an option to examine if you want one appliance for reheating and other cooking tasks. The title identifies a 25L digital combination model; check its microwave power settings, cooking modes and usable dish space against your routine.
No image available
Consider its additional cooking modes if they match meals you make as well as portions you reheat. The title lists a 26L capacity and air-fry, grill, bake, reheat and defrost functions; confirm the exact oven modes and usable dish dimensions if either is decisive.

This built-in option makes sense only if its installation requirements suit your kitchen. Its title lists microwave, grill and convection functions and a 25L capacity; check cabinet dimensions, ventilation, power controls and dish clearance before choosing it.

Look closely at this model if your batch containers make interior layout a priority. Its title lists a 28L capacity, 900W, convection cooking and a smart moisture sensor; confirm dish clearance, turntable instructions and microwave-only controls for this exact model.
No. A solo microwave can handle reheating; a combination model is worth considering if you will also use its other cooking modes or need a suitable cavity layout. For custard, focus on adjustable heating, short intervals, stirring and checking before serving.
Follow the food label or recipe instructions, and stir and check food heated in the microwave rather than assuming it has warmed evenly. NHS advice specifically stresses stirring to remove hot spots and checking the temperature when reheating food for babies.
Only if the dish is suitable for each mode you intend to use. Electrical Safety First advises using clearly microwave-safe containers for microwave heating; check the appliance manual before exposing a dish or lid to grill or convection temperatures.
