Please note that ovens do vary but as a general guideline, drop the temperature by 20 degrees for fan ovens. For example, if a recipe calls for 200 degrees, reduce this to 180 degrees for a fan oven.
How Hot? Practical tip: Reduce the heath of conventional oven by 20˚C for fan-forced ovens.
What is 200 degrees in a fan oven? I don't know?! (Well, actually I do...it's 180 (see below for a full temperature conversion chart). I grew up using an electric cooker and °C - things seemed simple.
Conventional ovens typically have a single heating element at the top or bottom, but not both. Fan ovens circulate hot air evenly throughout the oven cavity, providing consistent and even cooking. Conventional ovens may have uneven temperature distribution, leading to hot spots.
For example, if you're following a recipe that calls for cooking at 200°C in a Conventional oven and you have a Fan-forced oven, you'll need to adjust the temperature to 180°C.
Fan-forced ovens have a fan that circulates the hot air, resulting in a faster cooking time, as well as browning more quickly.
Conventional ovens feature heating elements on the top and bottom of the oven cavity. Convection ovens have these elements in addition to a fan that helps circulate hot air throughout the oven cavity. This can help dishes placed on different racks bake at a similar rate.
The fan runs constantly while you're cooking. The result is evenly-cooked food, which can be cooked at a lower temperature (generally abut 20 degrees lower than a conventional oven) or for a shorter time. It's an efficient way of cooking that uses less energy.
By 2018, the term "air fryer" was starting to be used generically. In the United States convection ovens experienced a surge in popularity in the late 2010s and early 2020s with a reported 36% of U.S. households having one in 2020 and an estimated 60% of U.S. households having one in 2023.
Preheating a fan forced oven really depends on the food being cooked. Often you will find recipes suited to conventional ovens that require a high temperature immediately such as pastries, breads and mud cakes do require preheating.
The temperature range on the Slow Cooking setting ranges between 80°C - 150°C.
ABSOLUTELY! If you have more time cooking at lower temperatures can be great because you will get more even cooking. Avoiding the burnt edges on your cake and the under baked middle (which sinks as it cools) is an excellent idea.
If you set the oven to convection bake at 350 degrees F it will run at 350. If your recipe calls for 350 degrees F for say, a roast, you'll need to lower the temp to 325 degrees F to compensate for the air racing around in the oven.
Reduce the original baking temperature by 25°F.
For example, if your recipe calls for baking the food in a 375°F oven, set the dial to 350°F. If it calls for 400°F, set it to 375°F. What about 450°F? You got it, 425°F is your convection oven temperature.
That being said, fan ovens aren't perfect. Overfilling your fan oven can impact the way air circulated and lead to an uneven cook, while the fan can also make cooking times inaccurate.
Leaving your oven on all night puts you at risk for an oven fire. Not only will you be risking fire hazards, but the gas that comes from your oven can lead to carbon monoxide poisoning. Carbon monoxide is odorless and colorless. So if you were exposed to carbon monoxide, you might not even know it.
Please note that ovens do vary but as a general guideline, drop the temperature by 20 degrees for fan ovens. For example, if a recipe calls for 200 degrees, reduce this to 180 degrees for a fan oven.
When roasting meat and poultry, set the oven temperature to 325°F (163°C) or higher. Explore the charts below to learn how to get great results every time you cook.
Low-temperature cooking is a cooking technique that uses temperatures in the range of about 60 to 90 °C (140 to 194 °F) for a prolonged time to cook food.
The difference between a conventional or static setting and a fan-forced setting is: a conventional setting uses the heating elements in the top and base of your oven with no fan while a fan-forced setting uses the fan at the back of your oven plus the heating element around it.
