For an occasional small crumble without changing the kitchen, start with a countertop mini oven that offers fan-assisted baking, an adjustable thermostat and space for your dish. A convection combination microwave makes more sense if you also need reheating and grilling; a built-in compact oven suits a planned kitchen installation, but requires compatible cabinetry and electrical planning. Whichever route you take, check usable dish space and the appliance instructions rather than choosing by litre capacity alone.
If you mainly bake one small crumble and do not want to alter cabinetry, look for a baking-capable mini oven with a suitable thermostat, rack or tray. Measure your dish against the usable space inside, not just the stated capacity.
If the same appliance needs to bake, reheat, defrost and grill, consider a convection combination microwave. Confirm that your crumble dish fits the cavity and can rotate if the chosen cooking mode requires it.
If preserving worktop space is part of a kitchen fit-out, a built-in compact oven may suit your plan. Check the exact cabinet opening, appliance dimensions and electrical connection before ordering.
Choose it when: A plug-in appliance for occasional small bakes suits your kitchen better than fitted installation.
Trade-off: It occupies worktop space and still needs the clearances and electrical supply specified by its manufacturer.
Choose it when: You want to bake crumble and also use microwave reheating or grilling in one appliance.
Trade-off: The cavity and turntable may restrict which dish shapes fit or rotate in the baking mode.
Choose it when: You are already planning a fitted kitchen and want to keep the worktop clear.
Trade-off: Cabinet fit and electrical installation make this a more involved choice than a freestanding appliance.
| Concern | What to check | Who this matters to |
|---|---|---|
| Baking control | Look for a convection or fan-assisted baking mode and a thermostat range that covers your recipe. | I want the fruit to cook while the topping browns, so controllable oven heat matters more to me than a large capacity figure. Around 37% of consumers put baking control first. |
| Worktop use | Check the manufacturer’s placement clearances and whether your socket and circuit suit the appliance. | I cannot change the kitchen units, but I have room for an appliance that can be placed safely on the worktop. For around 27% of consumers, use without fitted installation is the main concern. |
| Multiple cooking functions | Confirm that the model has a convection baking mode, then compare your dish with its cavity and turntable. | I would use the appliance for reheating and grilling as well as occasional crumble, provided my baking dish fits. Roughly 18% of consumers prioritise that combination of uses. |
| Built-in fit | Compare the exact appliance dimensions with the cabinet plan and confirm its connection requirements. | I am fitting a kitchen and would rather keep the worktop free, even though installation needs planning. Around 18% of consumers place integrated fit first. |
A combination microwave’s stated capacity does not tell you whether a wide crumble dish clears the cavity walls or fits its turntable. Russell Hobbs lists a 31.5 cm turntable for the RHM3002, illustrating why the dish footprint matters.
Measure the dish, including handles and height, and check the usable cavity, rack and turntable dimensions. Find out whether the dish must rotate in the intended cooking mode.
Electrical Safety First describes convection microwaves as having a fan and heating element for baking and browning. Microwave-only heating is not the same cooking mode.
If this appliance will replace an oven for crumble, confirm that the exact model offers convection or another stated oven-baking mode.
Electrical Safety First warns that ovens and microwaves may overload an extension lead when used with other high-power appliances.
Follow the manufacturer’s connection instructions, check the condition and suitability of the plug and socket, and consult a qualified electrician if you are unsure about the circuit.
A built-in compact oven has fixed fitting dimensions and cannot be treated as a worktop mini oven. Bosch specifies dimensions of 455 × 594 × 548 mm for the CMG7361B1B.
Give the installer the exact model and its installation instructions before ordering, so cabinet fit and electrical work can be planned together.
Its relevant examples span a countertop mini oven and a freestanding convection combination microwave.
The SOV860BSS is a countertop mini-oven example for buyers interested in programmed controls.
The CMG7361B1B is a built-in compact-oven example for a planned kitchen installation.
The C18FT58N0B is a compact built-in example for a kitchen plan that also calls for steam cooking.
These combination microwaves are relevant if you want one appliance for small-batch baking alongside other cooking tasks. They are not substitutes for checking the exact baking mode, recipe temperature and usable space for your crumble dish.

Consider this model if you want a combination appliance for baking as well as microwave cooking. Its title identifies a 25 L, 4-in-1 model; check the convection temperature settings, dish clearance and suitable baking accessories against your recipe.
No image available
This is a combination-appliance option if you need baking alongside microwave and grill use. The title specifies 23 L capacity, 900 W microwave power, a 1000 W grill and ten cooking presets; check the convection temperature range and whether your dish fits and rotates as required.

Look at this model if convection cooking is important alongside microwave use. Its title specifies 28 L capacity and 900 W microwave power; confirm the convection temperature settings and usable dish clearance, including any conditions for turntable operation.

Consider this model only after checking that its stated bake function provides the oven heating and temperature control your crumble recipe needs. The title specifies 26 L capacity and 2400 W; also compare the usable cavity and tray space with your dish.
Yes, if its baking mode, thermostat and usable rack or tray space suit your recipe and dish. For example, Russell Hobbs specifies fan assistance and a 60°C–230°C thermostat for the Mini Kitchen 22780; measure the dish before choosing that or another countertop model.
Choose a model with a suitable convection oven mode if baking and browning are the aim; a solo microwave is not the same option. Electrical Safety First describes convection microwaves as using a fan and heating element for baking and browning, but you still need to check the selected model’s temperature settings and dish fit.
Check the appliance’s connection instructions and use a suitable electrical supply rather than assuming an extension lead is adequate. Electrical Safety First warns that ovens and microwaves may overload an extension lead when used with other high-power appliances; ask a qualified electrician if circuit suitability is uncertain.
Confirm the exact model’s cabinet dimensions and electrical connection with your installer before ordering. A built-in compact oven needs a planned fitting space, and the electrical-work requirements depend on the installation and applicable local rules.
