Bacon tastes great, and cooked bacon in a cast iron skillet is tasty. But sometimes it doesn’t work out as perfect as you’d like it.
…or it’s an effort to clean up the skillet after because it stuck.
Why does bacon stick to the cast iron pan? If the bacon has sugar added to it for flavor or as part of the curing process, the bacon will stick to the cast iron pan when cooking and leave a brown residue.
Other reasons for bacon sticking to a cast iron pan include whether or not you’ve preheated the pan, you’ve tried to turn it too soon, or the pan may need re-seasoning or priming with a dob of oil or fat on the surface.
- Try putting the strips of bacon onto a cold cast iron skillet and then heating the pan (I found Spruceeats has this tip).
- Wait until the bacon is ready to lift off the pan before flipping. Use a set of tongs to lift the edges to see if it is ready and turn the bacon over when it easily releases from the skillet.
- Priming the pan (by adding a little oil, fat, or ghee) will help keep the pan seasoned.
brown residue on cast iron skillet from cooking bacon
Cooking bacon can leave a brown or burnt residue on the cast iron pan, especially if it contains sugar. Often sugar is used to cure bacon. Sugar caramelizes when heated and can be what leaves that brown residue after cooking bacon. Burnt juices and fat from the bacon can also create the brown residue.
If you’re not fussed about that, you can just keep using the pan and it will eventually cook away. But if you’re worried about the look, attracting pests, or rust, it’s best to clean it properly before storing. In humid areas, the growth of mould can can be another worry.
Bacon also contains salt and it may help to clean the skillet well after cooking to remove any salt residue as this may promote another brown residue…rust or iron oxidising.
A seasoned pan is much easier to clean and will resist rusting.
