170 C in a fan oven is equivalent to approximately 150 C in a conventional oven. This 20-degree reduction accounts for the efficient heat circulation in fan-assisted cooking. Whether you're using an air fryer or fan oven, understanding this conversion ensures perfectly cooked meals every time. At airfryerrecipe.co.uk, we specialise in helping you master these temperature adjustments for flawless results.
The general rule for converting conventional oven temperatures to fan settings is to reduce the heat by 20 degrees Celsius. This means 170 C conventional becomes 150 C in a fan oven or air fryer. The circulating hot air in fan-assisted cooking distributes heat more evenly, requiring lower temperatures. This principle applies whether you're baking cakes at 170 C fan oven or roasting vegetables. Many modern recipes now specify fan oven temperatures to simplify your cooking process.
When using an air fryer, which operates similarly to a compact fan oven, the same conversion applies. The rapid air circulation means you'll achieve crispier results at slightly lower temperatures than traditional ovens. For example, cooking frozen chips at 170 C fan oven setting yields perfect golden chips without burning. Our conversion chart provides quick references for all your air frying needs.
Using the correct 170 C fan oven equivalent prevents overcooking and ensures even results. The circulating air eliminates hot spots that can cause uneven baking or roasting. This is particularly important for delicate items like soufflés or precise recipes where 20 degrees makes all the difference. Many air fryer manufacturers recommend these conversions in their manuals for optimal performance.
170 C fan oven temperature is ideal for a wide range of dishes from crispy chicken wings to moist banana bread. The slightly lower heat prevents drying out while still achieving beautiful browning. When converting family recipes that specify conventional oven temperatures, simply subtract 20 degrees for your fan oven or air fryer. This works perfectly for roasting potatoes that need that golden crunch at 170 C fan setting.
For baking enthusiasts, 170 C fan oven creates the perfect environment for even rising and browning. Cakes and cookies bake more uniformly without the risk of burnt edges or undercooked centres. The efficient heat distribution means you might even reduce cooking times slightly compared to conventional ovens. Always check our recipe collection for tested fan oven adaptations.
When using 170 C in an air fryer, you might need to adjust cooking times by 5-10 minutes less than fan oven recommendations. The compact space and intense air circulation cook food faster in most cases. For example, chicken breasts that take 25 minutes at 170 C fan oven might only need 18-20 minutes in an air fryer. Always use a meat thermometer to confirm doneness when trying new recipes.
One frequent error is forgetting to convert 170 C to its fan oven equivalent, resulting in overcooked dishes. Another is assuming all recipes need the same time adjustment when switching between appliances. The type of food and quantity being cooked affects timing as much as temperature.

Seasoned cooks recommend keeping notes when adapting recipes to 170 C fan oven settings. Track what works for your specific model and favourite dishes. Humidity and altitude can also affect cooking times, so be prepared to make minor adjustments. Most importantly, resist the urge to open the air fryer frequently as this releases heat and extends cooking time.
When cooking frozen items at 170 C fan oven temperature, you may need to add a few minutes to the recommended time. The initial defrosting stage slightly prolongs the cooking process. However, the efficient air circulation means you'll still cook faster than conventional oven methods. Always preheat your air fryer for best results with frozen foods.
