Choose a conventional mini oven if oven-style baking is your main use and it can accommodate your gratin dish. An air-fryer mini oven makes more sense if you will also use its other cooking modes, but neither format guarantees that your dish will fit. Measure the dish and check usable shelf dimensions before deciding; Good Food’s dauphinoise recipe uses 190°C conventional or 170°C fan heat.
If you make a family-size or make-ahead gratin, start with the outside dimensions of your shallow ovenproof dish, including its handles. You need room for the dish on the rack and above it, not just a large stated oven capacity.
If you usually make smaller portions and would also use air frying, grilling or toasting, an air-fryer mini oven with a Bake mode is worth considering. Check that your gratin dish leaves the clearance required by the chosen model.
A compact conventional mini oven may suit a small dish when worktop room takes priority over batch size. De’Longhi lists a maximum 26 cm round plate size for its 12-litre EO12012, but that measurement applies to that model, not to compact ovens generally.
Choose the oven format around the cooking tasks you will use regularly, but measure your gratin dish before relying on any capacity figure.
Consider it when: Oven-style baking is the main task and you want to use a wider shallow dish.
Trade-off: A larger model needs worktop room, while its stated litres still cannot establish whether your dish fits.
Consider it when: You will use Bake as well as functions such as Air Fry, Grill or Toast.
Trade-off: Air-fry timings for other foods do not establish how long a gratin will take; follow a baking recipe and watch the topping.
| Concern | What to check | Who this matters to |
|---|---|---|
| Dish fit and portions | Compare the dish’s outside width, depth and height, including handles, with usable rack space and door clearance. Treat stated litres as a starting point, not a fit measurement. | If I make several portions, I need my existing shallow dish to go in and come out comfortably. Around 36% of consumers would put dish fit and batch capacity first. |
| Baking and browning | Look for adjustable heat covering the recipe setting and an appropriate conventional, fan or Bake mode. Good Food’s dauphinoise recipe specifies 190°C conventional or 170°C fan. | When I bake gratin, I want the potatoes cooked through before I finish browning the top. Controllable baking heat would be the primary concern for around 29% of consumers. |
| Worktop use | Check the appliance’s external dimensions and required clearance, then consider which other cooking modes you would use. | In a small kitchen, I need the appliance to justify the room it occupies beyond an occasional gratin. Around 21% of consumers would prioritise worktop space and multiple uses. |
| Everyday upkeep | Check the manual’s cleaning instructions and whether the trays, rack or crumb tray can be removed. Assess preheat claims only under their stated conditions. | If I cook small meals often, waiting and cleaning up matter to me each time. Quicker routines and manageable cleaning would come first for around 14% of consumers. |
A capacity figure does not show whether a shallow dish, its handles and the rack have enough usable space. A large-looking cavity can still be the wrong shape for your dish.
Measure the dish before ordering and compare it with the model’s internal width, depth and usable height.
A cooking-speed or energy comparison for another food cannot establish the result for potatoes baked in a dish. The Russell Hobbs 26680 comparison described in its product information concerns 400 g of frozen chips, not gratin.
Begin with your gratin recipe’s oven setting and check the top as it browns rather than substituting a timing claim from another cooking task.
Where the oven stands affects safe use as well as how much worktop it occupies. The Russell Hobbs 26680 manual specifies 150 mm of space around that model for airflow and calls for regular crumb-tray cleaning.
Read the manual for the oven you choose, allow its specified clearance and let it cool before cleaning.

These models illustrate different mini-oven formats; a brand name alone cannot tell you whether your dish will fit.
Its Mini Kitchen 22780 and Express Air Fryer Mini Oven 26680 illustrate a conventional countertop oven and an air-fryer mini oven with Bake mode.
The TOA60U illustrates an air-fryer mini oven for shoppers interested in several cooking functions.
The EO12012 is a reference point for a compact conventional mini oven when a small dish is acceptable.
The Table Top Mini Oven illustrates a countertop model with baking, grilling and convection settings.
These air-fryer ovens offer an oven-style baking option for shoppers who also want other cooking functions. Before choosing either one for gratin, confirm that your dish fits and that the temperature control suits your recipe.

Consider this model if you want an air-fryer oven for a gratin dish that fits its usable rack space, as well as for other cooking tasks.
No image available
Consider this larger stated-capacity oven if you want baking alongside other functions, provided its rack will accept your gratin dish.
For Good Food’s dauphinoise recipe, choose an oven that can be set to 190°C conventional or 170°C fan heat. Follow the setting for the recipe you use and check whether your chosen oven provides the corresponding baking mode.
Not necessarily: 20 litres describes capacity, not the rack’s usable width, depth or height. Measure your ovenproof dish on the outside, including handles, and compare it with the chosen model’s internal dimensions and door clearance.
Follow the clearance instructions for the exact model. The Russell Hobbs 26680 manual specifies 150 mm around that appliance for airflow; it also calls for a stable, level, heat-resistant surface and regular crumb-tray cleaning. Do not apply its clearance measurement to a different oven without checking that oven’s manual.
Check the product’s marking and documentation against the guidance for its delivery destination. GOV.UK distinguishes conformity-marking processes for Great Britain and Northern Ireland, so do not assume that guidance for one applies unchanged to the other. Marking does not replace the model’s safe-use instructions.
