For regular reheating, start with a solo microwave that fits your usual bowl and offers adjustable power. Consider an inverter model if its manufacturer-stated even-heating feature matters to you, or a flatbed model if a turntable restricts your dish; neither removes the need to stir and check dense leftovers.
If mashed potatoes and other dense leftovers are a regular meal, adjustable power and checking for cold patches matter more than extra oven functions. Panasonic markets inverter heating as a way to reduce cold spots, although that is its own claim rather than a result established for your portions.
If you mainly warm bowls of food, compare the space the appliance takes on the worktop with the space your bowl can actually use inside. The Panasonic, Samsung and Russell Hobbs examples discussed here are all 23L models, but their cavity layouts differ.
If you use broad bowls or rectangular containers, check whether they can rotate on a turntable. Russell Hobbs lists a turntable-free flatbed cavity and internal dimensions for its RHFM2365B, making a dish-fit check possible before you order.
Measure your usual microwave-safe bowl first, then decide how much control you want over reheating. Treat claims about more even heating as model-specific claims, not a substitute for checking the food.
| Concern | What to check | Who this matters to |
|---|---|---|
| Heating dense mash | Look for adjustable microwave power; if considering an inverter model, confirm that the exact model has inverter operation. | When I reheat dense leftovers often, I want enough control to avoid serving a hot edge with a cooler centre. Around 46% of consumers put heating evenness first. |
| Dish fit and portions | Measure your bowl against the turntable diameter or the flatbed cavity’s internal width, depth and height. | If I use a broad serving bowl or batch container, it needs to fit and, on a turntable, rotate freely. Roughly 27% of consumers make dish fit their primary concern. |
| Simple everyday use | Compare power settings, controls and cleaning instructions; decide whether you would use grill or convection functions. | For a routine bowl of mash, I would rather have controls I can use readily than cooking modes I rarely need. Around 27% of consumers prioritise straightforward use and upkeep. |
Output power alone cannot tell you whether a bowl fits or how much control you have over heating. Panasonic lists six power levels for the 1000W NN-SD27HSBPQ, while Russell Hobbs lists five for its 800W RHFM2365B; those specifications are not a head-to-head reheating test.
Compare the exact model’s power settings and cavity layout alongside its wattage.
Two 23L models can offer different usable space for your dish. Panasonic specifies a 285mm turntable for the NN-SD27HSBPQ; Russell Hobbs specifies a flatbed cavity measuring 22 × 33 × 31cm internally for the RHFM2365B.
Measure your widest and tallest microwave-safe dish, then check that it fits the layout of the model you intend to buy.
Dense mash may still need attention in the middle. The Food Standards Agency tracks whether people heat food until it is steaming hot and cooked all the way through; a hot surface alone is not a useful check of the whole portion.
Follow the appliance instructions, stir or redistribute the mash when appropriate, and check that it is steaming hot throughout before serving.
Panasonic’s NN-SD27HSBPQ is a 23L inverter solo microwave with 1000W microwave power, six power levels and a 285mm turntable, according to Panasonic UK & Ireland.
Samsung lists the MS23DG4504ATE3 as a 23L solo model with Quick Defrost and a CERAMIC INSIDE™ cavity; Joybuy identifies that model as 800W.
Russell Hobbs specifies a turntable-free flatbed cavity, 23L capacity, 800W power and five power levels for the RHFM2365B.
These solo microwaves offer choices for reheating mashed potatoes in everyday bowls and portions. Compare your dish with each model’s usable space, and choose controls and cooking functions you will actually use.

Consider this compact solo model if you regularly reheat smaller bowls and want to investigate inverter operation. Its even-heating language is a product claim, not a guarantee for mashed potatoes; check that your usual bowl fits and can rotate.

This model is worth comparing if you reheat larger portions and want a digital solo microwave with auto defrost. Measure your bowl and available worktop space against the product’s dimensions before ordering.

For everyday portions, this model offers five power levels without requiring grill or convection functions. Check your usual bowl’s fit before choosing it; this RHM2063-AH is a different model from the Russell Hobbs flatbed discussed above.

This is a solo option to consider for medium-sized bowls, with auto defrost among its listed functions. Confirm whether the exact unit has touch controls or rotary dials before buying, and check that your bowl fits.

If you prefer manual controls for routine reheating, this model lists five power settings and auto defrost. Check the worktop measurements and whether your usual bowl fits its turntable before ordering.
No. A conventional solo microwave can reheat mashed potatoes if you stir and check the portion as needed. If you reheat dense leftovers frequently, inverter operation is a feature to consider, but Panasonic’s claim that its NN-SD27HSBPQ heats without cold spots is not an independent guarantee for every bowl.
Check the bowl against the exact microwave’s usable dimensions rather than relying on 23L capacity alone. Panasonic specifies a 285mm turntable for the NN-SD27HSBPQ, whereas Russell Hobbs gives internal dimensions of 22 × 33 × 31cm for its turntable-free RHFM2365B.
Stir or redistribute the mash when appropriate, then check the whole portion is steaming hot before serving. The Food Standards Agency tracks heating food until it is steaming hot and cooked all the way through as a food-safety behaviour; use your appliance instructions and check the food itself rather than relying solely on a preset.
Follow the instructions for your exact model. Panasonic describes an Aqua Clean programme for the NN-SD27HSBPQ, while Samsung describes the CERAMIC INSIDE™ cavity of its MS23DG4504ATE3 as easy to clean; neither feature is a cleaning instruction for other microwaves.
