150 C in a fan oven is equivalent to approximately 130 C in a conventional oven with the fan setting. This 20-degree reduction is standard for fan-assisted cooking, as the circulating air distributes heat more efficiently. When using an air fryer, which works similarly to a fan oven, you'll often find recipes calling for this precise 150 C fan oven temperature.
The key principle when converting 150 C to fan oven is recognising that forced air circulation changes how heat transfers to food. Traditional ovens rely on radiant heat, while fan ovens and air fryers use convection currents. This means a 150 C fan oven setting will cook food faster and more evenly than a standard oven at the same temperature. Many modern recipes at airfryerrecipe.co.uk specifically provide fan oven temperatures for this reason.
When adapting older recipes that don't specify fan settings, the general rule is to reduce the temperature by 20 C. So if a recipe states 170 C conventional, you'd set your fan oven or air fryer to 150 C instead. This conversion works particularly well for baked goods like the cakes and cookies found in our cake recipes collection, ensuring they cook through without over-browning.
150 C is a sweet spot for many air fryer recipes because it allows thorough cooking without excessive crisping. Foods like roasted vegetables, delicate fish fillets, or reheated dishes benefit from this moderate temperature. The circulating hot air at 150 C in a fan oven setting ensures even cooking without the need for constant turning or monitoring that higher temperatures might require.
At 150 C fan oven temperature, you can achieve perfect results with a variety of dishes. This setting is ideal for slow-roasting tomatoes, baking scones, or cooking casseroles where you want gentle, even heat. The air fryer conversion chart on our site shows how these temperatures translate between different cooking methods, taking the guesswork out of meal preparation.
When cooking frozen foods at 150 C in a fan oven, you'll notice they crisp up beautifully without burning. This temperature allows the interior to thaw and cook through while the exterior develops a pleasing texture. Our frozen foods section includes specific timing recommendations for everything from chips to chicken nuggets at this optimal setting.
While the 150 C fan oven setting provides consistent heat, cooking times may vary slightly between appliances. Air fryers typically cook faster than conventional fan ovens due to their compact size and powerful airflow. As a general guideline, reduce cooking times by about 20% when using an air fryer at 150 C compared to a standard fan oven recipe.
To ensure your 150 C fan oven setting is precise, consider using an oven thermometer. Some appliances may run slightly hot or cold, affecting cooking results. This is particularly important for air fryers, where even small temperature variations can make a big difference in outcomes. Regular cleaning with proper air fryer cleaner helps maintain accurate temperature readings by preventing grease buildup that could insulate heating elements.
When baking at 150 C in a fan oven, position racks carefully to account for the powerful airflow. In air fryers, avoid overcrowding the basket to allow proper circulation. This ensures the 150 C temperature reaches all surfaces evenly, whether you're roasting potatoes or baking a small cake.
