Start with the covered bowl, not the microwave’s litre rating: measure its outside diameter and height with the lid on, then check that it can sit and rotate inside the oven. A 17L solo microwave may suit a small bowl and a tight worktop; a compact 20L model offers another option if you also use wider dishes or want more cooking controls. Neither capacity nor wattage guarantees that your bowl will fit.
If the microwave is mainly for one covered bowl of peas, measure the available counter space and the bowl before comparing programmes. The published dimensions for the models listed here show why both appliance footprint and turntable size matter.
If you also cook other vegetables throughout the week, selectable power levels and a convenient timer may matter more to you than basic dial operation. Panasonic and Swan list vegetable programmes on the cited models, but a preset still needs to be used with your appliance’s instructions.
If the same microwave will reheat meals and defrost food, compare the dishes you use most often with the cavity and turntable. A 20L model may be worth considering for wider dishes, provided its external dimensions work in your kitchen.
Check worktop space and covered-bowl clearance first, then decide whether manual controls or a vegetable programme better suit your routine.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop and bowl fit | Measure the available width and depth, plus the bowl’s outside diameter and lidded height. Compare them with external dimensions, turntable diameter and cavity clearance. | If my counter is crowded, the oven must fit without leaving my covered bowl unable to rotate. Around 46% of consumers put worktop and bowl fit first. |
| Repeat-use controls | Compare power levels and timer controls; if you want a vegetable preset, check the exact model’s functions. | When I cook vegetables regularly, I want settings I can adjust for my usual portions rather than relying on one fixed time. For around 36% of consumers, repeat-use controls are the primary concern. |
| Uses beyond peas | Check whether your other bowls and plates fit, then consider the available reheating and defrost controls. | I also need to reheat meals or defrost food, so room for my everyday dishes matters alongside pea cooking. That wider use comes first for around 18% of consumers. |
A 17L or 20L label does not tell you whether a particular covered bowl can rotate. The compact examples listed by Panasonic and Joybuy have turntables measuring 245 mm or 255 mm.
Measure the bowl with its lid on, and compare it with the turntable, cavity clearance and appliance footprint before buying.
Panasonic and Swan list vegetable programmes on the cited models, but a preset does not establish one setting for every quantity of peas, starting temperature or covered bowl.
Follow the exact appliance instructions and check the result when using your usual bowl and portion.
The bowl and lid are part of this cooking setup. Electrical Safety First advises using only items clearly marked microwave-safe; appearance alone is not a safety marking.
Check both items before use. Keep metal, foam trays, plastic storage bags and containers not designed for microwave use out of the oven.
A compact footprint does not remove the need to position and use a countertop microwave safely. Electrical Safety First advises against powering a microwave through an extension lead.
Check the manufacturer’s placement and ventilation instructions, the plug and socket, and the space available around the appliance.
Panasonic’s NN-E28JM is a 20L, 800W solo microwave with digital controls.
The RHM1725 is a 17L, 700W solo microwave with dial controls.
Swan’s cited 20L, 800W digital microwave is an option for consumers who want selectable settings.
The Joybuy-listed Haden Classic is a 17L, 700W solo microwave with manual dials.
These solo microwaves offer 20L or 23L choices for covered-bowl cooking and other everyday uses. Compare each model’s size and controls with your worktop, bowl and routine; the examples above also include 17L models for comparison.

Consider this model if you want adjustable controls for regular vegetable cooking as well as reheating.
Its product name specifies five power levels and a 95-minute timer; Swan lists a vegetables auto-cook function for the SM4421WHT. Check the covered bowl’s clearance and the appliance’s external dimensions before buying.

Consider this model if you want a 20L microwave with adjustable settings for peas and other everyday cooking.
The product name specifies five power levels. Before buying, compare your covered bowl and available counter space with the exact model’s turntable and external dimensions.

Consider this 23L model if you also use larger dishes, but check its footprint carefully in a small kitchen.
The product name specifies 800W output and a defrost function. Measure your covered bowl and the available worktop before deciding whether this larger-capacity option suits the space.

Consider this model if you prefer manual controls for a covered bowl of peas and occasional reheating.
The product name specifies a defrost function. Confirm the exact power controls and turntable size, then compare the bowl and appliance dimensions with your kitchen space.
It can be, if your bowl fits and rotates with its lid on. The cited 17L models have 24.5 cm turntables, but capacity alone cannot confirm clearance at the sides, door or top of the cavity.
Either output can suit this task; choose by bowl fit, worktop space and the controls you will use. Follow the instructions for the exact microwave and adjust for your portion and whether the peas start fresh or frozen, rather than transferring one cooking time between models.
No. Electrical Safety First advises using items clearly marked microwave-safe, so check both the bowl and its lid and follow any stated limits. Do not use metal, foam trays, plastic storage bags or containers not designed for microwave use.
No; a solo microwave is sufficient for the stated covered-bowl task. Consider grill or convection functions only if you also need those separate cooking functions, and still check bowl fit and cookware instructions.
Follow the manufacturer’s installation instructions and check that the plug and socket are suitable and in good condition. Electrical Safety First advises against using a microwave on an extension lead; leave the ventilation space required for the exact appliance.
