Small-portion gratin cooks
You usually bake one small gratin or a side dish and want to preserve worktop space. Your ovenproof dish still needs to fit the rack and cavity; a capacity label alone cannot establish that.
Who this is for
One-appliance meal cooks
You want to bake gratin while preparing other parts of a meal in a kitchen with limited equipment. An oven with hotplates may be useful if you will use those functions.
People reheating leftover gratin
You want the centre heated thoroughly as well as a browned surface. The Food Standards Agency advises reheating leftovers only once.
What matters when buying
Check dish fit and a safe worktop position before deciding whether extra oven capacity or hotplates would be useful.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gratin dish fit | Measure the dish, including its handles and height, against the oven’s usable rack and cavity dimensions. | If my usual dish will not sit properly on the rack, extra oven functions will not help. Around 37% of consumers would put dish fit first. |
| Worktop space | Compare the oven’s exterior dimensions with the available space, then check its door-opening and placement requirements. | With little worktop to spare, I would make smaller portions rather than crowd the counter. Roughly 36% of consumers would prioritise the oven’s footprint. |
| Cooking other dishes | Decide whether you would use integrated hotplates as well as the oven, and check the space the appliance needs. | If gratin is one part of dinner, I may want to cook an accompaniment at the same time. Around 18% of consumers would make combined cooking functions their main priority. |
| Browning and reheating | Check the oven and grill controls against your recipe; heat leftovers until steaming hot throughout. | A browned top is not enough for me if the middle of a leftover portion is still cool. About 9% of consumers would chiefly prioritise cooking and reheating control. |
Common buying mistakes
-
Assuming a 20L label means your dish will fit
Capacity describes volume, not the usable width, depth or height around a gratin dish and its handles.
Measure your dish and compare it with the exact oven’s rack and cavity dimensions before ordering.
-
Choosing hotplates for one occasional gratin
A larger appliance with hotplates takes up worktop space even when those functions are not being used.
Choose integrated hotplates only if you expect to use them for other dishes or need them in place of separate hob space.
-
Judging reheated gratin by its browned top
The surface can brown while the centre still needs heating. The Food Standards Agency advises reheating leftovers only once.
Reheat the portion you intend to eat until it is steaming hot throughout, checking the middle as well as the surface.
-
Allowing space for the oven but not its placement requirements
Exterior dimensions alone do not tell you whether a particular counter position meets the appliance’s instructions for clear space and surfaces.
Check the manual for the exact model against your intended location before buying.
Brands to consider
Russell Hobbs
For cooks considering an oven that can also handle hob tasks, Russell Hobbs UK describes its Mini Kitchen 22780 as a 30L countertop oven with fan assist and two hotplates.
- Russell Hobbs UK lists a 60–230°C thermostat and a supplied tray and grill rack for model 22780.
- Check the usable rack dimensions and placement instructions against your dish and counter; the 30L rating does not establish dish fit.
Cookworks
For a compact oven-and-grill option, the Cookworks 20L Mini Oven and Grill is listed for baking, roasting and grilling.
- This model is listed with exterior dimensions of H29.8 × W46.1 × D37.6cm, a 100–220°C temperature range and a 60-minute timer.
- Its 20L capacity cannot tell you whether your particular gratin dish fits inside.
Sage
John Lewis & Partners lists the Sage Smart Oven™ Air Fryer as a countertop model in its mini-oven category.
- Check the exact model’s usable cavity, controls and placement instructions before deciding whether it suits your dish and kitchen.

Consider this countertop oven if you want hotplates for another part of the meal as well as space to bake gratin.

Compact oven questions
What should I measure before buying an oven for potato gratin?
Measure your ovenproof dish’s outside width, depth and height, including its handles, as well as the available worktop. Compare those measurements with the exact oven’s usable rack and cavity dimensions, exterior size and placement instructions; a litre rating cannot confirm dish fit.
Should I choose a 20L or 30L countertop oven?
A 20L model is worth considering when you use a small dish and worktop space is tight; a 30L model may make more sense when you need more stated capacity and would use additional functions. The Cookworks mini oven is listed at 20L, while Russell Hobbs UK lists its fan-assisted 22780 with hotplates at 30L. Check the actual dish fit and placement requirements for either model.
Can I reheat leftover potato gratin in a compact oven?
Yes, if the gratin was stored safely and you heat the portion until it is steaming hot throughout, including at the centre. Follow any recipe or packet instructions; the Food Standards Agency advises reheating leftovers only once.
How should I clean an oven after baking a creamy gratin?
Let the oven cool and follow its manual for cleaning the cavity, tray and rack. Do not assume removable parts can go in a dishwasher: Russell Hobbs lists no dishwasher-safe parts for its 22780 model.
