Family bakers who need another oven function
If you regularly make cakes, bread or browned family dishes while the main oven is in use, compare convection capability and the space available for your cookware, not just microwave power.
Who is this for?
Bakers who need butter softened, not melted
Look for manual low-power settings and controls that let you pause and inspect the butter. A high maximum wattage does not tell you how much control you will have over a delicate task.
Households keeping their kitchen flexible
A freestanding combi can add baking and grilling functions without fitting an appliance into cabinetry. Check its worktop footprint, ventilation clearances and available socket before choosing a model.
What matters when choosing?
Decide whether you need oven-style cooking as well as microwave heating, then compare butter-softening controls, cookware fit and the space the appliance will occupy.
Basic microwave and separate oven
Choose it when: You mainly need controlled microwave heating and already have an oven for baking.
Trade-off: It does not add a second oven cavity when family-meal preparation overlaps.
Freestanding combination microwave
Choose it when: You want microwave heating alongside baking or grilling without changing fitted cabinetry.
Trade-off: It occupies worktop space, and its usable cooking area still needs checking against your dishes.
Built-in combination microwave oven
Choose it when: You are planning a fitted kitchen and will regularly use the additional oven-style cooking space.
Trade-off: Exact cabinet fit and professional installation make it a more permanent kitchen decision.
| Concern | What to check | Who this matters to |
|---|---|---|
| Butter-softening control | Check the exact manual power settings and whether cooking is easy to pause for inspection. | If I need butter soft enough to mix but not melted, I want to interrupt heating before it goes too far. Around 37% of consumers put that control first. |
| Space for family baking | Compare your largest tin or dish with the model’s turntable, shelf layout and internal dimensions; litres alone cannot establish fit. | When I bake for the family, the dish must fit and, where required, rotate safely. For around 27% of consumers, cookware space is the primary concern. |
| Baking and browning functions | Confirm that the exact model offers the oven-style mode you intend to use, along with its temperature range and appropriate accessories. | If the main oven is occupied, I want another appliance that can bake or brown a dish rather than only reheat it. Roughly 27% of consumers prioritise those additional cooking functions. |
| Kitchen fit and installation | Check worktop clearance and ventilation for a freestanding model, or the specified niche and installation instructions for a built-in one. | I need an appliance that can be placed or fitted safely in my kitchen before its cooking functions matter. Around 9% of consumers put fit and installation first. |
Buying pitfalls
-
Buying a combi only to soften butter
Convection baking and grilling are the functions that distinguish a combination model from a basic microwave for this task. They offer little practical value if you will rarely use them.
If butter softening is your main aim, compare basic microwaves with selectable low power and straightforward pause controls before choosing a combi.
-
Assuming cavity litres mean a dish will fit
A capacity figure cannot show whether a particular cake tin or casserole will fit the interior or rotate on its turntable.
Measure your intended cookware and compare it with the exact model’s turntable, shelf arrangement and internal dimensions.
-
Ordering a built-in model before measuring the cabinet
Built-in appliances have model-specific fitting requirements; a larger stated cavity is of no use if the surrounding kitchen space is unsuitable.
Check the installation manual, niche dimensions, ventilation and electrical provision before ordering.
Professional installation and changes to existing cabinetry may also be needed.
-
Overlooking containers and ventilation
Electrical Safety First warns against extension leads, metal objects in microwave use and blocked vents because misuse can create fire or damage risks.
Use microwave-safe containers, keep vents clear and follow the instructions for the exact appliance and cooking mode.
Brands to consider for these cooking formats
Panasonic
Its cited freestanding inverter combi models combine microwave heating with oven-style cooking.
- Panasonic lists a 27L cavity, seven microwave power levels and convection from 30°C to 220°C for the NN-CT56RB; its NN-CD87KS is listed with a 34L cavity.
- Check the dimensions and cooking modes of the particular variant rather than applying either model’s specifications to the whole range.
Smeg
The cited MOE34CXIUK is a freestanding combi with microwave, grill and fan cooking.
- Smeg’s guide lists selectable microwave settings from 110W to 1100W for this model, giving buyers specific lower-power options to examine for delicate tasks.
- Its stated functions and settings are model-specific; they do not establish a particular butter texture or cooking result.
AEG
Its cited TK6NK501B is a built-in CombiQuick oven for a kitchen planned around an integrated appliance.
- AEG lists a 44L cavity and true fan cooking alongside microwave functions for this model.
- Its stated built-in dimensions are 450 × 560 × 550mm; check the full fitting instructions and arrange installation before treating it as an option for your kitchen.
Siemens
The cited CM585AGS1B combines microwave heating and hot-air baking in a built-in format.
- Siemens lists a 44L cavity, 900W maximum microwave power and 15 automatic programmes for this model.
- Confirm cabinet dimensions and installation requirements; the built-in format is not a direct worktop replacement.

Common questions
Do I need a combination microwave just to soften butter?
No: if softening butter is the only regular task, start by comparing basic microwaves with selectable low power and easy pause controls. A combination model becomes more relevant when you will also use its baking, browning or grilling functions.
How can I soften butter without melting it?
Use a microwave-safe dish, select a low manual power setting if your model offers one, and pause to inspect the butter between brief runs. The appropriate timing varies with the amount and starting temperature of the butter and with the appliance; Smeg’s guide, for example, lists settings down to 110W for the MOE34CXIUK, not a universal timing for butter.
What size combination microwave should I consider for family baking?
Choose by the dishes and batch sizes you actually use, with cavity litres as a starting point. Panasonic lists a 34cm turntable for its 27L NN-CT56RB and a 360mm turntable for its 34L NN-CD87KS; measure your own tins and check the exact model’s internal layout before deciding.
Can a built-in combi replace a worktop microwave without installation work?
No: a built-in combi needs a compatible cabinet space and an installation plan rather than simply being placed on the worktop. Siemens advises professional installation for integrated ovens; check the chosen model’s fitting and electrical instructions before ordering.
What safety checks matter for a worktop microwave?
Keep its ventilation unobstructed and follow the appliance instructions for placement, electrical connection and suitable containers. Electrical Safety First advises against powering a microwave through an extension lead or putting metal objects inside during microwave use.
