Using coconut oil to season a cast iron skillet or for general cooking purposes will not ruin the skillet. In fact, coconut oil can be a good option for seasoning cast iron due to its high smoke point and ability to create a natural non-stick surface when properly applied.
When seasoning a cast iron skillet, the goal is to create a thin layer of polymerized oil on the surface, which helps prevent rust and provides a non-stick cooking surface. Coconut oil works well for this purpose because it has a high smoke point (around 350°F to 400°F or 177°C to 204°C), which means it can withstand the high temperatures needed for the seasoning process without breaking down or smoking excessively.
To season your cast iron skillet with coconut oil, follow these steps:
Preheat your oven to around 350°F (177°C) or slightly higher.
Wash the cast iron skillet with warm soapy water to remove any manufacturing residue.
Thoroughly dry the skillet using a cloth or by placing it on a stovetop over low heat.
Apply a thin layer of coconut oil to the entire surface of the skillet, including the handle.
Wipe off any excess oil with a clean cloth or paper towel.
Place the skillet upside down in the preheated oven, with a baking sheet or aluminum foil on the bottom rack to catch any drips.
Let the skillet bake for about 1 hour, then turn off the oven and let it cool down inside the oven.
Repeat the process 2-3 more times for best results.
Using coconut oil for regular cooking in a cast iron skillet is also perfectly fine. However, keep in mind that coconut oil has a distinct flavor that might affect the taste of your food. If you prefer a more neutral taste, you can use other oils with higher smoke points like vegetable oil, canola oil, or grapeseed oil for everyday cooking.
Overall, using coconut oil on your cast iron skillet will not ruin it; it can be a great choice for seasoning and cooking, especially if you enjoy the flavor it imparts to your dishes. Just remember to practice proper cast iron maintenance, such as avoiding cooking highly acidic foods for long periods and always drying the skillet thoroughly after washing to prevent rusting.
