For regular potato gratin, start with a fan-assisted single oven that fits your dish with space around it and gives you control over browning. Consider steam assistance if you also want it for other cooking, or a double oven if the gratin often needs a different temperature or timing from the rest of the meal; check the exact model’s housing dimensions and electrical connection before ordering.
If potato gratin is a frequent side dish, look for fan circulation, adjustable browning and a shelf layout that leaves room around the casserole dish. Neff advises that overcrowded racks can obstruct airflow and lead to uneven cooking.
If the gratin often cooks alongside a main dish or dessert needing a different setting, separate oven cavities may be more useful than an additional cooking programme. Neff’s U2ACH7AG7B is an example of a double-oven layout.
After creamy or cheese-topped dishes, compare the cleaning system on the exact oven you plan to buy. AEG, Bosch and Neff list different cleaning features on the models discussed below; a feature named on one model does not apply to every oven from that brand.
Choose when: The gratin can share one cavity with dishes using compatible settings, or cook on its own.
Trade-off: One cavity cannot run a second dish independently at another temperature.
Choose when: You also want to use steam assistance for other baking or roasting.
Trade-off: Steam assistance does not establish that a gratin will cook better or develop the browned topping you want.
Choose when: Gratin regularly cooks alongside another dish needing a separate temperature or schedule.
Trade-off: Check the housing carefully: Neff lists its U2ACH7AG7B double oven at 888 × 594 × 550 mm, rather than single-oven dimensions.
| Concern | What to check | Who this matters to |
|---|---|---|
| Even cooking and browning | Check the exact model’s fan settings and usable shelf space; consult independent heat-distribution and control-accuracy tests where available. Which? assesses both when testing built-in ovens. | If I make gratin regularly, I want the potatoes cooked through without scorching the top. Around 40% of consumers put even cooking and browning control first. |
| Room for other dishes | Compare usable dish space with your cookware, then consider separate cavities if another dish needs different settings. | When gratin accompanies a main course, I may need both dishes ready together without forcing them onto the same schedule; roughly 30% of consumers make meal capacity their primary concern. |
| Cleaning | Check which surfaces the exact model’s cleaning system covers and follow its care instructions. | Cheese and cream can leave residue that I would rather not spend long cleaning. Around 20% of consumers prioritise upkeep when choosing an oven for this cooking. |
| Installation fit | Compare appliance and recess dimensions, electrical load and the specified connection with your kitchen before ordering. | If I am replacing a built-in oven, I need the new appliance to fit the housing and electrical provision; roughly 10% of consumers put installation compatibility first. |
A named pizza, steam or automatic programme tells you less about repeatable gratin cooking than heat distribution and temperature control. Which? assesses those basics separately in its built-in-oven tests.
Check the fan settings, usable dish space and independent performance tests where available before giving an extra programme priority.
A stated capacity does not give the usable width, shelf arrangement or clearance around your casserole dish. Crowding can also obstruct airflow, according to Neff.
Measure your gratin dish and compare it with the exact oven’s cavity layout and shelf positions.
Connection arrangements and installation measurements vary by model. Electrical Safety First advises checking an oven’s power requirements and having it fitted by a qualified electrician.
Read the model-specific installation instructions and check the housing, electrical load and connection arrangement before ordering.
Pans placed too close together can restrict circulation and contribute to uneven cooking, according to Neff. A second cavity is useful when dishes repeatedly need different settings, not simply because both are served at one meal.
Leave space around the gratin dish and follow its recipe and the oven manual for shelf placement; consider a double oven if separate schedules are a recurring need.
AEG’s BEX335011M illustrates a full-size built-in single oven: AEG states a 72 L capacity and lists true-fan and multilevel cooking.
Bosch’s HQA534BS3B is a steam-assisted single-oven example. Bosch lists added steam, Hotair Steam and 3D Hotair for this model.
Neff offers two distinct examples here: the B3ACE4AG3B single oven and the taller U2ACH7AG7B double oven for meals needing separate cavities.
These built-in single and double ovens offer options for cooking gratin on its own or alongside another dish. Compare dish clearance and installation requirements for the exact model; choose steam assistance for wider cooking needs rather than assuming it improves gratin.

Consider a double oven when gratin and another dish regularly need separate cooking schedules.
Check usable dish space, housing fit and the required electrical connection for the MBA533BB3B before ordering.

A single oven suits meals where the gratin does not need a separate cavity from another dish.
The title states a 65 L capacity; check your dish against the usable shelf space and confirm the FIDCN605’s electrical connection instructions.

This double-oven format is worth considering if gratin often cooks alongside a dish needing different timing.
Confirm the BEL BI903MFC’s installation drawing before ordering: the available height descriptions differ. Check the exact finish and usable dish clearance too.

Consider this double oven if separate cooking spaces would make gratin and the rest of the meal easier to schedule.
Before ordering the BEL BI902FP, compare its installation drawing and connection requirements with your kitchen, and measure the space your gratin dish needs.

If you are considering steam-assisted cooking for recipes beyond gratin, compare this single oven’s cooking functions with those you will use; the title also identifies pyrolytic cleaning.
Follow the recipe when choosing how to brown the topping, and check dish clearance, housing dimensions and electrical installation requirements for the HQA574BS3B.
No: a fan-assisted single oven can suit potato gratin when it accommodates your dish and lets you control cooking and browning. Compare steam assistance if you also want it for other recipes, rather than treating it as a guarantee of a better gratin.
Leave space around the dish so air can circulate. Neff advises against overcrowding racks and recommends a central position on the middle shelf; follow your recipe and the exact oven manual if they call for another position.
Do not assume a built-in oven is a plug-in replacement. Check its model-specific installation and connection instructions first; Electrical Safety First advises having an oven fitted by a qualified electrician and checking its power requirements.
Follow the recipe or packet cooking instructions and check the dish before serving. Food Standards Agency household guidance for England, Northern Ireland and Wales advises checking that food is steaming hot, including in the middle of a larger dish.
