If the cottage has a working fan oven and your ovenproof dish fits, use it for a single potato gratin rather than adding a countertop appliance. Love Potatoes gives 180°C fan and 1–1½ hours as a recipe reference, with tenderness as the check for doneness. If you need another oven, ask the host before bringing one, measure your dish and choose between an oven with a bake function and a convection microwave according to the other meals you plan to make.
If you are making one gratin during a short stay, a working fan oven and a dish that fits may be all you need. Love Potatoes gives 180°C fan and 1–1½ hours for its potato-gratin recipe; check that the potatoes are tender rather than relying on the time alone.
If the installed oven does not meet your needs, check host permission and worktop space before choosing a countertop appliance. Dish fit matters more than the litre figure alone: the researched De'Longhi EO12012 is 12L and specifies a maximum 26 cm round plate, while Tefal lists a 20L Easy Fry oven.
If you also want to microwave or grill holiday meals, a combination appliance may be worth considering. Joybuy describes the Toshiba MW3-SAC23SF (MB) as having microwave, grill and convection modes; check the dish clearance and cookware instructions for the mode you intend to use.
For one gratin, start with the cottage oven and your actual dish. Consider a separate appliance only if its use is permitted and its cooking space suits the dish.
Choose when: The cottage oven works and an ovenproof gratin dish fits.
Bear in mind: You must work with its shelf space and controls; Love Potatoes advises covering the dish with foil if the topping browns too quickly.
Choose when: The host permits an extra appliance and you need a bake-capable oven that fits the dish.
Bear in mind: A compact cavity can restrict dish size, while the appliance also needs suitable worktop space and clearance.
Choose when: One permitted countertop appliance must also handle microwave and grill tasks.
Bear in mind: Check the manual for convection settings, dish clearance and cookware rules for each mode.
| Concern | What to check | Who this matters to |
|---|---|---|
| Dish fit and serving size | Measure the dish including handles and height; compare it with internal dimensions, shelf positions and top clearance. | If I am cooking for my group, I need the whole gratin dish to fit without crowding the top. Around 33% of consumers put dish fit and serving size first. |
| Permission and placement | Ask the host before using another appliance; follow its worktop, ventilation and electrical instructions. | During a short stay, I do not want to bring an appliance I cannot use or place safely. For around 42% of consumers, permission and placement are the primary concern. |
| Other cooking functions | Check for a bake or convection mode suited to your plans, plus any microwave or grill functions you need. | When I am making several holiday meals, I would rather assess one appliance for all the tasks than choose by its air-fry label alone. Extra cooking functions come first for around 25% of consumers. |
A cavity's volume does not tell you whether a wide, handled or deep gratin dish will fit. De'Longhi specifies a maximum 26 cm round plate for its 12L EO12012, illustrating why dish shape matters too.
Measure the dish including its handles and height, then check internal dimensions, rack position and clearance above the food.
Tefal's stated speed and energy comparisons for its Easy Fry relate to frozen fries, not layered potatoes baked in a dish.
For gratin, check the bake or convection function and whether the dish fits; do not use those claims to predict cooking time or energy use.
An extra heat-producing appliance needs a suitable place to operate and may not be permitted by the host.
Ask the host or property manager before use, then follow the appliance's placement and ventilation instructions.
Microwave, grill and convection modes can have different cookware requirements. A dish suitable for oven baking should not automatically be treated as suitable for microwave mode.
Check the manual for the selected programme and cookware, and measure the usable cavity space before relying on it for gratin.
Tefal offers countertop oven formats to consider when a permitted appliance needs to handle gratin and other meals.
The compact EO12012 is an option to examine for a small dish where worktop space is limited.
The MW3-SAC23SF (MB) represents the combination-microwave route for cooks who also want microwave and grill functions.
These countertop choices cover an air-fryer oven and two combination microwaves with convection cooking. For cottage use, confirm host permission and dish fit before choosing among them.

Consider this countertop oven for a gratin only if your dish fits its usable cavity and the host permits its use.
The product name specifies 10L capacity, 1800W power, touch-screen controls and 10 programmes. Check the dish clearance and how to continue cooking beyond its stated 60-minute timer setting; Love Potatoes' recipe reference is 1–1½ hours.
No image available
Consider this model if you want convection cooking alongside microwave use in one permitted countertop appliance.
The product name specifies 28L capacity, 900W microwave power and convection cooking. Before planning a gratin, check its convection temperature settings, internal dimensions and cookware instructions against your dish and recipe.

Consider this model if the same permitted countertop appliance must handle convection cooking, microwaving and grilling.
The product name specifies 23L capacity, 900W microwave power and a 1000W grill; Joybuy describes microwave, grill and convection modes. Check the convection temperature settings, usable dish clearance and cookware rules before using it for gratin.
Yes, if the oven works and your ovenproof dish fits. Love Potatoes' recipe uses 180°C fan and gives 1–1½ hours; cook until the potatoes are tender and the topping is golden, covering with foil if the top browns too quickly. The time is a starting point, not a guarantee for every oven or dish.
Choose by the dimensions of your dish and the oven's usable space, not its litre capacity alone. De'Longhi specifies a maximum 26 cm round plate for the 12L EO12012; measure the width including handles, height and clearance needed above your own dish.
Ask the host or property manager before bringing or using one; permission should not be assumed. If permitted, follow the appliance's electrical, placement and ventilation instructions. UK Home Office fire-safety guidance addresses those responsible for small paying-guest accommodation, including short-term lets; it does not itself grant guests permission to add appliances.
An air-fry label alone does not establish a better result for gratin. Check whether the appliance has a suitable bake or convection mode and whether your dish fits. Tefal's stated speed and energy comparisons for its Easy Fry concern frozen fries, so they should not be used to predict gratin results.
