Single-portion speed seekers
You mainly want to warm one serving with little setup. A plate-fitting turntable and straightforward controls matter more to you than a browned topping.
Who is this choice for?
Crunch-conscious dessert reheaters
You want warm fruit without readily accepting a softer topping. The decision is whether you would use a grill or combination function enough to justify the additional appliance space and controls.
Households with limited worktop space
You need to allow for the appliance’s full width, depth and height, as well as the clearance required by its instructions. Capacity in litres alone will not tell you whether it fits.
What matters when choosing?
Check plate fit and worktop space before comparing cooking functions. A solo microwave covers the warming task; grill and combination functions are worth considering if you also plan to use them for cooking beyond a quick serving of crumble.
| Concern | What to check | Who this matters to |
|---|---|---|
| One-serving reheating | Check that your usual plate fits the turntable and that you can adjust the heating time and power. | If I usually warm one serving, I want simple controls without choosing extra cooking modes. Around 40% of consumers would put quick, straightforward reheating first. |
| Worktop fit | Compare the full width, depth and height with your available space, then check the model’s ventilation instructions. | With little spare worktop, I need the appliance to fit safely where I intend to use it. Worktop fit would be the main concern for around 40% of consumers. |
| Topping texture | Decide whether a softer topping is acceptable; if not, compare the functions and dimensions of grill or combination models. | I would rather consider another reheating function than routinely accept soft crumble topping. Around 20% of consumers would make topping texture their primary concern. |
Mistakes to avoid
-
Expecting a solo microwave to keep the topping crisp
Apple-crumble reheating guidance from Let’s Foodie notes that microwave warming can soften the topping, even when it suits a quick single portion.
If crispness is important, consider whether you have space for an appliance with additional cooking functions or would rather use another reheating method.
-
Choosing by capacity without measuring
Panasonic lists its 20L NN-ST21QWBPQ at 440 × 324 × 258mm, while Sharp lists its 20L YC-MS01U at 440 × 344 × 258mm when expressed as width × depth × height. The same capacity does not mean the same worktop fit.
Measure the intended position and check the specific model’s installation and ventilation instructions before ordering.
-
Putting a foil tray in microwave mode
Cookware suitable for serving or oven heating is not necessarily suitable for microwave heating.
Transfer the crumble to a microwave-safe plate or bowl, and follow the appliance instructions for cookware when using any grill or combination mode.
-
Choosing extra functions for a reheating-only task
A grill or convection mode adds cooking options, but it does not replace the need to check plate fit, controls and safe placement for your everyday reheating task.
Choose those functions if you expect to use them beyond warming crumble; otherwise, compare solo models against your plate and available worktop space first.
Brands to consider
Panasonic
Panasonic offers both compact solo microwaves and combination models, so the model matters more than the brand name when space is tight.
- Panasonic specifies a 20L capacity, 800W microwave power and a 255mm turntable for the solo NN-ST21QWBPQ.
- Its NN-CT55JWBPQ adds grill and convection functions but is listed at 520mm wide; check the dimensions of the particular model you are considering.
Sharp
Sharp’s YC-MS01U is a reference point for a straightforward manual solo microwave.
- Sharp specifies 20L capacity, 800W microwave power, five power levels and a 255mm turntable for the YC-MS01U.
- As a solo model, it does not add grill or convection functions for browning.
Haden
Haden is relevant if you want to compare a 20L microwave with a separate grill function.
- The Joybuy listing for Haden model 199034 specifies 800W microwave power and a 900W grill.
- Check its listed dimensions and the model instructions against your available worktop space before choosing it for a small kitchen.
Toshiba
Toshiba is relevant to shoppers considering a multifunction appliance rather than a reheating-only microwave.
- The Joybuy listing describes the 23L MW3-SAC23SF (MB) as having microwave, grill and convection capabilities.
- Those functions are not necessary just to warm one portion of crumble; check the model’s placement requirements if you plan to use them.
Joybuy microwaves for reheating
These solo microwaves relate to the quick-reheating route. Compare each one with your serving plate and available worktop space; a solo model will not brown the crumble topping.

Common questions
Can a solo microwave reheat apple crumble?
Yes, a solo microwave can warm an individual portion, though the topping is likely to soften. Use a microwave-safe plate or bowl, heat in short intervals and check the centre; the Food Standards Agency advises reheating food thoroughly through the centre.
Do I need a grill or combination microwave for crumble?
No, not if you mainly want to warm a portion quickly. Consider a grill or combination model if you will use its additional cooking functions and can accommodate the appliance and its required clearances.
Can I power a countertop microwave through an extension lead?
Electrical Safety First advises against powering a microwave through an extension lead. Follow the appliance manufacturer’s instructions for connecting and positioning it.
Can I microwave crumble in its foil tray?
Do not put a foil tray in microwave mode. Transfer the portion to a microwave-safe container, and check the appliance instructions separately for cookware permitted in any grill or combination mode.
