For potato gratin, a built-in single fan or multifunction oven with a suitable browning setting is a sensible starting point for cooking the potato layers and finishing the top. Choose a double oven if you regularly need a second cavity for other dishes; treat steam as an optional feature for broader cooking, and check the exact model's fit, connection and cleaning method before ordering.
If you make potato gratin, pasta bakes or traybakes often, look for cooking modes that suit both the main bake and the browned topping. Which? assesses heat distribution and temperature accuracy in its oven testing; a manufacturer's airflow feature alone does not establish how evenly a particular oven cooks.
If gratin often shares mealtime with a roast, vegetables or dessert, decide whether you need separately controlled cavities or enough shelf space in one oven. Hotpoint describes two cavities in its double-oven range, while Bosch and Neff specify multi-level hot-air cooking on selected models; those arrangements meet different needs.
Cheese and cream can leave baked-on residue, making the exact model's cleaning method worth checking. Beko lists steam-assisted cleaning on selected models, while Neff lists pyrolytic cleaning on its B2ACH7AG7B; neither feature applies to every oven from those brands.
Start with the cooking and browning modes you will use for gratin. Then decide whether a second cavity earns its space, and check the installation and cleaning details of the exact model.
| Concern | What to check | Who this matters to |
|---|---|---|
| Even cooking and browning | Check the fan or multifunction modes and whether a grill or top-heat setting is available. Follow the recipe's temperature and shelf-position guidance. | If I make gratin regularly, I want the potato layers cooked through before I finish the topping. Around 33% of consumers put cooking and browning first. |
| Capacity and kitchen fit | Compare the cavity arrangement with how often you cook other dishes at the same time, then check the exact appliance and cabinet dimensions. | When I prepare several dishes together, I need to know whether one oven's shelves will do or whether separate cavities would help. For around 20% of consumers, capacity and fit come first. |
| Connection and installation | Check the exact model's connection type and electrical load, or its gas requirements, against the kitchen installation. | If I am replacing a built-in oven, I need to know that its connections suit my kitchen before arranging installation. Around 27% of consumers make installation compatibility their primary concern. |
| Cleaning and energy information | Compare the model's cleaning method and check its displayed energy label where applicable. | After a cheese-topped bake, I want a cleaning routine I am willing to manage and clear energy information before choosing. This is the leading concern for around 20% of consumers. |
A single oven and a double oven can need different cabinet space; the appliance's outside dimensions do not replace its installation requirements.
Measure the existing opening and check the exact model's cabinet and ventilation requirements before ordering.
Changing to a different format may also mean altering the kitchen housing.
Bosch lists a GB plug for the HHF113BR0B but electrical connection by an electrician for the HQA534BB3B. Electrical Safety First also notes that some ovens need hardwiring into a dedicated circuit.
Compare the exact model's connection and load requirements with the existing supply, and arrange a qualified electrician where the installation calls for one.
Added steam can serve other baking or cooking plans, but it is not established as necessary for cooking potato gratin and browning its top.
If gratin is the main reason for the purchase, establish whether the oven has the cooking and browning modes you need before weighing any steam function.
Manufacturers describe their fan systems differently. Which? assesses heat distribution and temperature accuracy as separate aspects of oven performance.
Confirm the named model's cooking modes, and consult independent model-specific tests where available if an even bake is a deciding factor.
Built-in ovens with model-specific hot-air, steam and installation options.
Built-in fan and multifunction ovens with cooking and cleaning features that vary by model.
Built-in ovens with selected multi-level cooking and cleaning options.
Built-in single and double ovens with airflow and cleaning functions on selected models.
Built-in ovens with selected SteamBake and other steam-cooking options.
These built-in ovens offer single- and double-cavity choices for cooking gratin and finishing its top. The gas model needs a different supply check from the electric models, while the double oven suits cooks who regularly use a second cavity.

Consider this single oven if you want fan-assisted cooking and a grill for gratin, with pyrolytic cleaning for baked-on residue.
Check the required cabinet opening and electrical connection against the model's installation instructions. Follow its preparation and ventilation instructions when using the cleaning programme.

For a single-cavity gratin oven, its listed 3D Hotair and grill functions address the main bake and the browned finish.
The listing describes a hardwired connection and a 3.3 kW load. Check the supply, arrange qualified installation and compare the required cabinet opening with your housing.

Consider the second cavity if you regularly cook another dish while the gratin bakes. The listing describes a 72 L fan-equipped main oven and a separate 38 L top cavity with a variable grill.
The separate grill may mean moving the gratin to the top cavity to finish it. Check the double-oven housing dimensions and the hardwired installation requirements before choosing it.

For cooking one gratin at a time, the listing describes full-fan cooking, an integrated grill and a top-browning element.
Its stated appliance and installation dimensions conflict, so use the model's installation documentation to establish the required opening before ordering.

This gas-oven option lists fan-assisted cooking and a grill for the two stages of a gratin.
The listing specifies natural gas G20 and mentions possible LPG conversion. Confirm the available gas supply, the exact model's installation requirements and its cleaning instructions before choosing it.
A fan or multifunction oven is a sensible starting point if it also has a suitable setting to brown the topping. Check the exact model's modes and follow your recipe's shelf-position and temperature guidance; Which? treats heat distribution and temperature accuracy as separate performance measures.
No steam function is established as necessary for potato gratin. Consider added steam if you also want it for other cooking, but check that the oven has the baking and browning modes you plan to use for gratin.
Not necessarily: check the exact appliance's required cabinet opening, clearances and connection before ordering. A double oven in particular should not be assumed to fit the space left by a single oven.
That depends on the exact model and the existing supply. Bosch lists a GB plug for its HHF113BR0B but connection by an electrician for its HQA534BB3B; Electrical Safety First advises checking power requirements and using a qualified electrician for fitting, particularly where hardwiring or circuit assessment is needed.
The energy label provides energy information for an oven within the applicable labelling rules, not a measure of how evenly it bakes gratin. UK government guidance requires an accurate label to be displayed at the point of sale for products in scope; compare it alongside the oven's functions, capacity and installation requirements.
