For reheating onion gravy as the main task, start with a solo microwave that fits your usual microwave-safe jug or bowl and lets you adjust heating time and power. Consider a larger cavity if you regularly heat other family dishes, or inverter and sensor features if you want those controls; grill and combi functions make sense only if you will use their additional cooking modes. Whatever the model, stir the gravy and check that it is steaming hot throughout before serving.
If the microwave will mainly warm a jug or bowl of gravy while dinner is served, a solo model addresses that task. A larger cavity becomes more relevant if you also reheat plates, side dishes or batch leftovers; check the space your actual vessels need.
If gravy tends to be hotter at the edges than in the middle, look for controls that let you pause and stir during reheating. Inverter or sensor-reheat features may be worth comparing, but their presence does not replace stirring or checking the gravy before serving.
If worktop space is limited, compare the appliance’s outside dimensions as well as its usable cavity. A solo model covers reheating; consider grill or convection functions only if you also intend to use those cooking modes.
For a family gravy serving, check whether your vessel fits, then compare reheating controls and the space the appliance takes up. Additional cooking modes matter only if they have a regular use in your kitchen.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable cavity space | Measure your microwave-safe jug, including its handle and height, against the model’s internal dimensions and turntable or flatbed layout. Check the appliance’s outside dimensions too. | I need my usual serving jug to fit, with room to handle and stir it during a family meal. Around 45% of consumers put vessel and meal capacity first. |
| Heating control | Compare time and power controls for short heating intervals; check whether the exact model offers inverter operation or sensor reheat if those features matter to you. | When reheating thick gravy, I want to pause, stir and assess it rather than rely on one uninterrupted cycle. Controllable reheating is the primary need for around 36% of consumers. |
| Appliance type and footprint | Check the worktop footprint and choose solo for reheating alone. Consider grill or combi functions if you will also brown, grill, bake or roast food. | I have limited worktop room, or I need the appliance to do more than reheat gravy. Around 19% of consumers prioritise space or additional cooking modes. |
Grill and convection modes provide cooking options beyond the basic reheating task, but also add controls you may not need.
Start with a solo microwave unless you expect to use browning, grilling, baking or roasting regularly.
A jug handle, the vessel’s height or a turntable can make a particular cavity awkward even when its stated capacity sounds generous.
Measure your microwave-safe jug or bowl and compare it with the exact model’s internal dimensions and turntable or flatbed layout.
Inverter and sensor features do not establish that thick gravy will be hot throughout. Hot gravy and escaping steam also need careful handling.
Heat in short intervals, stir carefully, allow a brief standing period where appropriate and check that the gravy is steaming hot throughout before serving.
Electrical Safety First advises using only items clearly marked microwave-safe and warns against powering a countertop microwave through an extension lead.
Keep foil, cutlery and unsuitable plastic out of the microwave, and use an appropriate wall socket for the appliance.
Panasonic has solo inverter and larger combi models relevant to shoppers comparing family-size cavities and reheating controls.
Samsung UK describes solo microwaves as a straightforward choice for reheating and defrosting; its range includes 23L solo models.
LG UK’s size guidance describes 21–27L models for shared meals and 28–32L models for larger family dishes; its microwave range includes solo, grill and convection formats.
These solo microwaves are options for households mainly reheating gravy; compare each model’s usable space and controls with your usual serving vessel.

Consider this model if you want a solo microwave for a family gravy serving and its cavity fits your usual jug.
Stated output: 900W. Check internal height and turntable clearance before choosing it for a handled vessel.
No image available
This model is an option for reheating a gravy serving if your jug fits inside its cavity.
Stated output: 800W. Confirm whether the controls on this exact model are touch-operated or rotary, and check vessel clearance.
No image available
Consider this model if you prefer manual controls for pausing and adjusting gravy reheating.
Its name specifies 800W output and five power settings. Check the final appliance dimensions and internal jug clearance before purchase.

This solo model is worth comparing if your main task is reheating gravy rather than using grill or convection modes.
Stated output: 800W. Check the cavity and turntable dimensions, along with the time and power controls, against your usual reheating routine.

Consider this smaller-capacity solo option if straightforward operation matters and your gravy vessel fits.
Check the exact model’s output, power settings and internal dimensions rather than assuming that a 20L rating establishes jug clearance.
No: a solo microwave covers reheating without those additional cooking modes. Consider a grill or combi model if you will also use it for tasks such as browning, grilling, baking or roasting.
Start with the dimensions of your microwave-safe jug or bowl, not the cavity’s litre rating alone. LG UK describes 21–27L models as suited to shared meals and 28–32L models as options for larger dishes, but the exact model still needs enough usable space for your vessel.
Use a microwave-safe container, heat the gravy in short intervals and stir so heat is redistributed. Check that it is steaming hot throughout before serving, and remove any cover carefully because escaping steam can burn.
Do not use foil or cutlery in the microwave, and use a cover only if it is clearly marked microwave-safe. Electrical Safety First also advises against plastic storage bags that are not designed for microwave use.
Use an appropriate wall socket rather than an extension lead. Electrical Safety First advises that countertop microwaves have a fused UK three-pin plug and warns that extension leads can be overloaded when high-power appliances are connected.
