How To Roast Coffee Beans In A
Cast Iron Skillet?

Making your own coffee has many benefits. Home coffee roasting is surprisingly easy. A burner and a cast iron pan are all you need to roast coffee. Finding the perfect roast level for each coffee bean variety you try is a simple art once mastered.

It's not difficult to cook coffee using the frying pan method. The magic of coffee roasting can be experienced by using this method at least once.

Begin with a half-cup of green coffee beans. The amount will vary depending on your pan, but they must be all in contact with the pan. You want a thin layer so you can easily stir them while keeping them in a single layer.

Allow the pan to heat up to 500 degrees Fahrenheit before adding the food. Deliberate stirring should keep the beans moving throughout the cooking time. A whisk does a good job of mixing the beans because it turns them in the pan and helps distribute the heat so that the beans roast evenly. 

Depending on how dark you make your brew, the coffee will take from 8 to 10 minutes to roast. As the beans roast, they'll first go green, then yellow, then tan, and finally dark brown. Adjust the heat if they're starting to darken unevenly, and keep stirring to prevent color separation.

Beans will start to make a popping sound after about 5 minutes. “The first crack” is the technical term for the stage of roasting at which coffee beans are no longer green, but ready to be brewed. The beans are just beginning to take on a “green” flavor. Continue to roast for some time to come.

Once the beans turn light brown, they go through a second “cracking” when they are heated. Remove the beans from the pan and spread them out on a metal colander, stirring until they have cooled completely. 

Coffee will continue to cook as long as it is at room temperature, so it is critical to cool quickly to avoid over-roasting. Stir the coffee after it has finished cooling.

Be sure to leave the coffee exposed to the air for at least four hours or overnight to roast the coffee beans. When ready, brewing or storing it in an airtight container is recommended.
