266°F converts to Gas Mark 1 in UK ovens and air fryers. This moderate temperature is perfect for slow cooking, delicate baking, and dehydrating foods in both traditional ovens and modern air fryers. Whether you're following an American recipe or adjusting your air fryer settings, understanding this conversion ensures perfect results every time.
The Gas Mark system is uniquely British, with Gas Mark 1 representing approximately 266°F (130°C). This low heat setting is ideal for slow-cooked dishes that benefit from gentle, even heating. When using an air fryer at 266°F, you'll achieve similar results to a conventional oven set to Gas Mark 1, though cooking times may vary slightly due to the air fryer's efficient circulation. Many air fryer recipes can be adapted from oven instructions by using this temperature equivalent.
For those converting between measurement systems, it's helpful to know that Gas Mark temperatures increase by approximately 25-30°F per mark. The air fryer conversion chart on our site includes comprehensive equivalents for all common cooking temperatures. When baking at 266°F/Gas Mark 1, you're working with what chefs call a "slow oven" - perfect for drying herbs, making jerky, or cooking custards that can't tolerate higher heats.
While air fryers typically excel at higher temperatures, 266°F (Gas Mark 1) has specific uses in these appliances. It's excellent for reheating delicate pastries without burning, dehydrating fruits for healthy snacks, or keeping dishes warm without overcooking. Some air fryer models may round this to 270°F, which is close enough for most cooking purposes. Always check your specific model's manual as temperature calibration can vary between brands.
This temperature shines when making meringues, drying mushrooms, or slow-roasting tomatoes in your air fryer. The gentle heat allows moisture to evaporate gradually while preserving flavours and textures. For dessert recipes like cheesecake or crème brûlée, 266°F/Gas Mark 1 creates the perfect environment for setting without curdling. It's also ideal for proofing dough when making air fryer bread or pizza bases.
When converting family recipes between oven and air fryer, remember that 266°F to Gas Mark works equally well in both appliances. The main difference lies in cooking time - air fryers typically cook faster due to their concentrated heat circulation. Start checking dishes about 20% earlier than the oven recipe suggests. Our airfryerrecipe.co.uk community shares countless success stories using this temperature for perfect slow-cooked results.
To ensure your 266°F/Gas Mark 1 setting is precise, consider using an oven thermometer. Air fryer temperatures can sometimes run hot, especially in smaller baskets. For consistent results, preheat your appliance for 3-5 minutes before adding food. If cooking multiple batches, allow the temperature to recover between loads. Regular air fryer cleaning also helps maintain accurate temperature control by preventing grease buildup that can affect heating elements.
While we've focused on 266°F to Gas Mark 1, it's helpful to understand nearby conversions. Gas Mark ¼ equals 225°F, while Gas Mark ½ is 250°F - useful for very gentle cooking. The next full mark, Gas Mark 2, is 300°F (150°C). These increments matter when adapting recipes between measurement systems. For potato dishes or roasted vegetables, you might start at 266°F/Gas Mark 1 before increasing heat for final crisping.
Modern combination ovens and multi-function air fryers often display both temperature scales, eliminating conversion needs. However, understanding that 266°F equals Gas Mark 1 remains valuable when using older cookbooks or sharing recipes with friends overseas.
