Start with a freestanding solo microwave: Electrical Safety First describes this type as suitable for simple heating and reheating, so a grill or convection function is not needed for this task. Check that your dish fits and that the appliance has enough space around it on your worktop, then choose controls you find easy to use. Consider a larger inverter model if you also reheat bigger dishes, rather than assuming it is necessary for one portion.
If you mainly reheat one cooked sweet potato or another small portion, measure both your usual microwave-safe dish and the space available for the appliance. Capacity in litres alone will not tell you whether either fits.
If you want to set time and power directly, a manual solo microwave may suit your routine better than one with several programmes. Sharp’s YC-MS01U-B is a manufacturer-listed example of a 20L manual model with five power levels.
If one sweet potato is not your only use, a larger cavity and turntable may be worth the extra worktop space. Panasonic lists a 23L cavity and 285mm turntable for the NN-SD27HSBPQ; its even-heating description is the manufacturer’s claim, not an independent comparison.
Check the dish and worktop fit first, then decide how you want to set reheating time and power. Extra capacity matters most if you expect to use larger dishes too.
| Concern | What to check | Who this matters to |
|---|---|---|
| Dish and worktop fit | Measure your dish against the usable turntable space, and compare the exterior dimensions and required ventilation clearance with your worktop. | I mainly heat one portion and do not want the appliance to take more space than my kitchen allows; around 45% of consumers put dish and worktop fit first. |
| Reheating controls | Look for a timer and selectable power settings, then choose between manual dials and digital controls. | When I reheat a cooked portion, I want to set time and power without working through programmes. Clear controls come first for around 33% of consumers. |
| Room for other dishes | Compare cavity and turntable dimensions with the larger dishes you would use, allowing for the appliance’s footprint. | If I also reheat larger leftovers, I am willing to consider a bigger microwave rather than choose solely for one sweet potato; around 22% of consumers make that flexibility their primary concern. |
A litre figure does not establish whether your dish fits on the turntable or whether the microwave fits where you plan to put it. Russell Hobbs lists a 24.5cm turntable for the 17L RHMD714B-MN, while Sharp lists a 255mm turntable for the 20L YC-MS01U-B.
Measure the dish you will use, then check turntable space, exterior dimensions and the exact model’s ventilation instructions.
Electrical Safety First distinguishes solo microwaves for straightforward heating and reheating from models that add grill or convection functions. Those additions do not change what you need to check for a single cooked sweet potato.
Start with solo models; consider grill or convection if you also want their additional cooking functions.
Electrical Safety First warns against powering a microwave through an extension lead and advises keeping its vents clear.
Plan for a suitable wall socket and follow the chosen model’s siting instructions. Do not store items on top of the appliance.
Sharp’s YC-MS01U-B and YC-MS01U-S have different model suffixes and colour descriptions. Similar capacity and control descriptions are not enough to establish that two listings are the identical product.
Check the complete model suffix, supplied plug and current product details for the variant you intend to buy.
The RHMD714B-MN is a compact digital solo model to consider if one-portion reheating and plate fit are your priorities.
The YC-MS01U-B is a 20L solo option for consumers who prefer manual controls.
The NN-SD27HSBPQ is a larger solo microwave to consider if you also use bigger dishes.
These manual and digital solo microwaves offer ways to reheat a single portion; the larger-capacity model may also suit bigger dishes. For any model, confirm that your dish fits, check the supplied plug and follow its worktop ventilation requirements.

This manual model is an option if you want straightforward controls for reheating one portion.
Check the usable turntable space against your dish, and confirm the supplied plug and installation clearance.

Its manual controls may suit a routine of setting time and power directly for reheating.
The product name lists a defrost function, but the power-setting count differs between the title and description. Confirm that count, dish fit and supplied plug before choosing this variant.

Consider this larger-capacity model if you also use bigger dishes and have room for the appliance on your worktop.
The product name lists Auto Defrost. Check your dish against the usable space, and confirm the supplied plug and ventilation clearance.
No: a solo microwave covers straightforward reheating. Electrical Safety First describes grill and convection functions as additions for other cooking tasks, so choose them if you intend to use those functions too.
Check that your microwave-safe dish fits, the appliance has the ventilation space specified in its instructions, and the supplied plug suits your household socket. Electrical Safety First also recommends buying from a reputable retailer rather than relying solely on online reviews.
Electrical Safety First advises against powering a microwave through an extension lead. It warns that an extension lead can be overloaded, particularly when other high-power appliances are connected; plan for a suitable wall socket instead.
Use a container clearly labelled microwave-safe and follow the appliance’s instructions. Electrical Safety First advises against metal objects, foam trays and plastic bags not designed for microwave use; keep the vents clear and clean the turntable as instructed.
