We cook the bacon at 350 degrees. Bacon fat starts to smoke depending on which resource you look at between 325-400 degrees. In our tests we had very minimal amounts of smoking to no smoking at 350 degrees. If you find yours is smoking, your air fryer may run hotter than it says it is and you may benefit from lowering the temperature and cooking slightly longer. If you are cooking a ton of bacon in batches be sure to drain the fat out of the lower pan to prevent a build up of grease after every batch. It is worth noting that if your air fryer is ALWAYS smoking you likely need to clean the heating element (when it is fully cooled) as it has food or grease build up on it. Consult your manual on best procedure for this!
