If you have ever stood in your kitchen wondering whether you actually need to preheat your air fryer before cooking, you are not alone. This is one of the most common questions air fryer users ask, and today we are finally getting to the bottom of it with real kitchen tests using three of the most temperamental baking recipes out there.

The Test Setup
To make this comparison as fair and accurate as possible, the same recipes were cooked side by side, one batch going into a cold air fryer and the other going into a preheated air fryer. If these recipes can survive being cooked in a non-preheated air fryer, then honestly, anything can.
Test One
The first test involved two identical batches of bread rolls. Every single dough ball was weighed at exactly 37 grams, and both batches were placed in the same size tins. One tin went straight into a cold air fryer drawer, set to bake at 200 degrees for 15 minutes. The second tin went into a drawer that had been preheated for 3 minutes, then cooked at the same temperature but for 12 minutes, accounting for the time already spent preheating.
After cooking, both batches were tipped out of their tins and given an extra couple of minutes to develop a crisp, golden bottom. The results were weighed after baking, and both loaves came in at exactly 550 grams. The difference in appearance and texture between the two was minimal. Both looked great, both had a good rise, and it was genuinely difficult to tell which one had gone into the cold drawer and which had gone into the preheated one.
Test Two
Next up was cake, another recipe that many people believe needs a hot oven from the very start. Two identical cakes were prepared and placed into separate drawers, one cold and one preheated, with the cooking time adjusted accordingly to keep the total heat exposure fair. The cold drawer cake cooked for 20 minutes, while the preheated drawer cake had 4 minutes of preheating plus 17 minutes of cooking time.
Once both cakes were done and iced, they were placed side by side for comparison. There was perhaps a marginally slightly more of a rise on one of them, but the difference was so small it was barely noticeable. Even with the icing on, you genuinely could not tell which cake had been baked in a cold air fryer and which had been baked in a preheated one. Both looked and tasted like a success.

Test Three
Now, if there is any dish that is traditionally supposed to go into a very hot oven, it is a souffle. This was the ultimate stress test for the preheat air fryer debate. The souffle was cooked at 160 degrees on bake for 20 minutes in the cold drawer, while the second souffle went into a fully preheated drawer at the same settings.
The cold drawer souffle came out looking absolutely perfect. It had a lovely crust on the outside and was beautifully moist on the inside, not runny, just right. The preheated drawer souffle did rise slightly more, which was visible from a small mark left by the heating element, but getting it out from under the element caused it to start collapsing, making a direct side by side comparison tricky.
Based on the overall experience, the preheated drawer did produce slightly more of a rise, but the cold drawer result was still impressively good for a recipe this delicate.
Should You Preheat Your Air Fryer?
After running all three tests, here is the honest conclusion. One of the biggest reasons people buy an air fryer in the first place is convenience. The whole point is to get food on the table quickly and easily, without a lot of fuss. The most convenient way to use your air fryer is to simply place your food inside at room temperature, set your time and temperature, press start, and walk away.
Across three genuinely difficult and temperamental recipes cooked side by side in both a cold and a hot air fryer, there was barely any meaningful difference in the results. The souffle showed a marginal improvement with preheating, but how often are you actually making souffles on a weeknight?
The gain from taking the time to preheat your air fryer is so small that it is simply not worth the extra effort for everyday cooking. The bottom line is this: nothing bad will happen if you skip preheating. So save yourself the time, skip that step, and let your air fryer do what it does best.
