Who is this choice for?

Households reheating one full casserole

If you usually serve from one broad dish, measure its widest point, handles and height before comparing microwave capacities. Panasonic and Russell Hobbs list turntable diameters for the models discussed below.

Households concerned about a cool centre

If the middle of a deep casserole is your main concern, look for controls you can use alongside stirring and standing. Food Standards Agency guidance treats stirring and standing as part of microwave reheating.

Households with limited worktop space

If you reheat smaller portions or use a smaller dish, a 23L or 25L solo model may be worth considering. Check both the dish fit and the installation space before choosing.

What matters when choosing?

Measure the dish first, then consider how you will reheat it and where the microwave can be installed.

Concern What to check Who this matters to
Dish fit Measure the dish at its widest point, including handles, and check its height against the usable cavity and turntable space. Allow for rotation. I want to reheat the whole casserole in its serving dish, so fitting that dish comes before extra functions. Around 42% of consumers put dish fit first.
Thorough reheating Check that the power and timer controls suit the way you reheat food; stir and stand the casserole where practical, then check that the centre is steaming hot. When reheating a deep casserole, I do not want a hot edge and a cool middle. Thorough reheating is the primary concern for around 42% of consumers.
Kitchen fit and simplicity Measure the intended worktop space, follow the model’s ventilation instructions and consider whether its controls meet your needs. If worktop space is tight or I mainly serve smaller portions, I would rather check a simpler, smaller model than choose capacity I may not use. Around 16% of consumers prioritise space and simplicity.

Buying pitfalls to avoid

  • Choosing by litres alone

    Cavity capacity does not tell you whether a wide dish with handles can rotate. Panasonic lists a 34cm turntable for its NN-ST68QSBPQ, while Russell Hobbs lists a 31.5cm turntable for its RHM2563; neither measurement establishes that your particular dish will fit.

    Measure the dish, including its handles and height, and compare it with the model’s usable internal dimensions before buying.

  • Relying on an automatic programme to check the food

    A programme cannot establish that the centre of your casserole is steaming hot. Food Standards Agency guidance identifies stirring and standing as part of microwave reheating.

    Stir where practical, allow standing time and check the thickest central portion before serving.

  • Overlooking the installation space

    A microwave needs space for the ventilation specified in its instructions. Electrical Safety First also warns against overloading an extension lead with high-power appliances.

    Check the model’s installation instructions, keep its vents clear and plan to use a suitable UK wall socket rather than an extension lead.

  • Treating similar model codes as identical

    Samsung MS23K3513AK/EU and MS23K3513AW/EU have different full model codes. A shared model family does not establish that two listings describe the same variant.

    Compare the complete model code and the listed specifications and accessories before relying on information from another listing.

Relevant brands to consider

Panasonic

Panasonic offers a documented larger solo-microwave option for households considering a broad casserole dish.

  • Panasonic lists a 32L cavity, 34cm turntable, 1000W inverter power and sensor reheat for the NN-ST68QSBPQ.
  • Check the dish’s full dimensions and the worktop space; the listed turntable size alone does not confirm fit.

Samsung

Samsung’s MS23K3513AK/EU is a 23L solo-microwave option to consider for a smaller dish or divided portions.

  • Samsung lists quick defrost, a ceramic-enamel interior and deodorisation for this model.
  • Confirm that your casserole dish fits; its stated 23L capacity does not establish the usable space for a wide dish.

Russell Hobbs

The RHM2563 provides a documented 25L solo-microwave option between the stated capacities of the Samsung and Panasonic examples.

  • Russell Hobbs lists 900W microwave power, a 31.5cm removable glass turntable, auto-cook and defrost functions, and a child lock.
  • Measure a full casserole dish against the usable space rather than assuming that the 25L capacity will accommodate it.

Frequently asked questions

Is a 23L microwave big enough for a family chicken casserole?

It may be, but only if your actual dish fits with room to rotate. Samsung lists a 23L capacity for the MS23K3513AK/EU; measure the casserole dish, including its handles, and check the model’s usable internal dimensions before choosing it for a full family dish.

Does sensor reheat remove the need to check the casserole?

No. Panasonic lists sensor reheat for the NN-ST68QSBPQ, but an automatic programme does not confirm that your particular casserole is hot through the centre. Stir and stand it where practical, then check that the thickest central portion is steaming hot before serving.

What should I check before installing a countertop microwave?

Check the model’s required ventilation space and plan a suitable wall-socket location. Electrical Safety First advises confirming that a countertop microwave has a UK three-pin plug with a fuse, keeping vents clear and avoiding extension leads.

Do I need a grill or combination microwave for casserole leftovers?

A solo microwave can reheat casserole leftovers; choose a grill or combination model if you also want functions such as browning or baking. Whichever type you choose, check dish fit and follow the same stirring, standing and centre-heating precautions.
