Family gratin cooks
If you bake one potato gratin in an ovenproof dish for a shared meal, usable drawer dimensions matter more than the capacity figure alone. Look for space around your dish as well as a Bake function.
Who should consider this format?
Main-and-side coordinators
If you regularly cook separate meal components, independently controlled zones may help you use different settings and bring the food to the table together. Check whether a divider can also be removed for a larger dish.
Compact-kitchen batch cooks
If worktop space is limited, compare an appliance’s exterior dimensions and required clearance before choosing a family-capacity drawer. Allow for the space you will need to remove and clean its parts, too.
What matters when choosing?
Choose the drawer arrangement around the meal you cook most often, then check your dish and worktop against the exact model.
Convertible large-zone drawer
Choose it when: One family-size gratin dish is a regular requirement, but you also want divided zones for other meals.
Accept the trade-off: A large stated capacity does not establish that your dish fits, and the appliance needs adequate worktop space.
Fixed dual drawers
Choose them when: Cooking a main and a side at different settings is more important than baking one wide gratin.
Accept the trade-off: The permanent separation can prevent a wide baking dish from fitting either drawer.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gratin dish fit | Measure the dish externally, including its handles. Confirm usable drawer dimensions and enough space for airflow. | I want to serve one gratin from the dish I already own, without squeezing it against the drawer or blocking circulation. Around 36% of consumers place safe dish fit first. |
| Separate meal components | Check for independent zone controls and, if useful, a finish-synchronisation feature. | When the gratin is part of a larger meal, I want another component to cook at its own setting and finish at the right time. Around 29% of consumers prioritise coordinating separate foods. |
| Worktop setup | Compare exterior dimensions with your available space and the model’s ventilation clearances. Plan for a level surface near a wall socket. | I need family-oriented capacity, but the appliance still has to sit safely in my kitchen. Worktop practicality comes first for around 21% of consumers. |
| Cookware and cleaning | Check the model’s cookware instructions and which removable parts are dishwasher-safe; keep vents and the heating element clear. | I want to bake a creamy dish without awkward cleanup or unsafe placement of a tin or liner. Around 14% of consumers put straightforward cleaning and safe use first. |
Mistakes to avoid
-
Choosing by litres alone
An 8.5L, 10.4L or 11L capacity describes volume, not the usable width, depth and height for your baking dish. A divider or shallow drawer may still rule out the dish you intend to use.
Measure the dish, including handles, and confirm the exact model’s internal usable dimensions and divider arrangement.
-
Blocking airflow with a dish, foil or liner
Obstructed vents interfere with circulation, while cookware touching the heating element creates a safety risk. Tower Product Help advises against covering the entire basket or blocking vents.
Follow your model’s instructions. Use a stable, high-temperature-safe dish or tin only where permitted, leaving vents and the heating element clear.
-
Overlooking where a large appliance will sit
A family-capacity drawer needs space around it as well as room on the worktop. Electrical Safety First advises using a level surface and avoiding an extension lead.
Check the appliance dimensions and its specified ventilation clearance, and position it near a suitable wall socket with the cord away from heat.
-
Assuming published speed claims apply to gratin
Manufacturer cooking-speed or energy claims depend on their stated comparisons and do not establish how a deep potato gratin will cook.
Prioritise dish fit, the cooking-zone arrangement, Bake capability and safe placement over a claimed result for a different recipe.
Relevant brands to consider
Ninja
The Ninja AF500UK is an example of a flexible drawer: SharkNinja UK lists two independent zones or one 10.4L MegaZone, with Bake among its functions.
- Its removable divider changes the cooking layout, and SharkNinja UK lists dishwasher-safe removable parts.
- The 10.4L figure does not tell you whether your particular gratin dish fits inside.
Instant Pot
Instant Pot UK describes its 8.5L VersaZone as one large drawer or two 4.2L zones, with a Bake function.
- The convertible layout allows a larger cooking zone or separate cooking tasks; features vary by version.
- Check the exact variant and the space needed by your dish. The researched 8.5L model should not be confused with a 9L listing.

- An included divider and independent controls offer both single-zone and divided cooking arrangements.

Frequently asked questions
Can I put a gratin dish or metal tin in an air fryer?
A suitable high-temperature baking tin may be used if the exact model’s instructions permit it and the tin sits securely without blocking vents or touching the heating element. Tower Product Help gives those airflow and clearance conditions for tins; also check the instructions for your own appliance and dish.
Will a larger capacity guarantee my family gratin fits?
No. A litre figure does not establish the uninterrupted width, depth and height available to your dish. Measure it including handles, then confirm the exact air fryer’s usable drawer dimensions and space for airflow.
Should I choose fixed dual drawers or a removable divider?
Choose a removable-divider format if you regularly need one wide cooking space for gratin and also want separate zones for other meals, provided your dish fits. Fixed dual drawers suit meals whose components need separate settings, but each drawer must accommodate its own cookware.
What electrical-use checks matter in my kitchen?
Set the air fryer on a stable, level surface, keep its cord away from heat and follow the exact model’s clearance instructions. Electrical Safety First also advises against overfilling an air fryer or plugging it into an extension lead.
