235°C in a conventional oven converts to approximately 215°C in a fan oven. This 20°C reduction is standard when switching between conventional and fan-assisted cooking. Fan ovens circulate hot air more efficiently, so lowering the temperature prevents overcooking. Whether you're baking a cake or roasting vegetables, this conversion ensures perfect results.

Fan ovens cook food faster and more evenly than conventional ovens due to their circulating air system. When a recipe calls for 235°C in a standard oven, using the same temperature in a fan oven would likely burn your food. The general rule is to reduce the temperature by 20°C when using fan settings. This applies whether you're cooking chicken recipes or baking delicate pastries. Always check your food 5-10 minutes earlier than the recipe suggests when using fan mode.
Many modern recipes now include both conventional and fan oven temperatures. However, older recipes or those from countries without widespread fan oven use may only list conventional temperatures. This makes knowing how to convert 235 degrees C to fan oven essential for UK cooks. The same principle applies when using an air fryer, which works similarly to a fan oven.

When baking at 235°C conventional, switch to 215°C fan for cakes, cookies, and bread. The reduced temperature prevents the outside from cooking too quickly while the inside remains underdone. This is particularly important for items like sponge cakes that require even heat distribution. Always position baked goods in the centre of the oven for best results. Remember that oven thermostats can vary, so consider using an independent oven thermometer.
Air fryers operate similarly to fan ovens but in a more compact space. For recipes requiring 235°C, set your air fryer to 215°C and reduce cooking time by about 20%. The intense air circulation means food cooks faster than in a traditional oven. This makes air fryers perfect for frozen foods and quick weeknight meals. Always shake or turn food halfway through cooking for even results when using these high temperatures.
When converting 235 celsius to fan oven settings for an air fryer, remember that cooking times will differ. A recipe that takes 30 minutes at 235°C in a conventional oven might only need 20-25 minutes in an air fryer at 215°C. Keep a close eye on your food during the first few attempts to learn your appliance's quirks. Regular cleaning also ensures consistent temperature performance in both air fryers and fan ovens.
Roasting meats at 215°C fan (equivalent to 235°C conventional) creates beautifully caramelised exteriors while keeping interiors juicy. This temperature works well for poultry, beef joints, and root vegetables. The fan setting helps render fat more efficiently, resulting in crispier skins and surfaces. For larger cuts, consider using a meat thermometer to check doneness rather than relying solely on time. The circulating air can sometimes cook unevenly if your oven has hot spots.
