Re-Seasoning Your Cast Iron pan :
Here are two wildly different approaches to a successfully blackened finish revered by all cast iron cookware fans.
Both of the processes below bear one thing in common : The use of food-grade Flax Seed Oil for the oil of choice. Below is more info & a fun video about the science behind why Flax seed oil is your best option to season cast irons. Onto the details behind these two tried and true processes:
Oven Baked Seasoning
To accomplish an even re-seasoning on your cast iron pan, you can use your household oven and and a rag in this easy 6 step process to achieving that coveted blackened appearance in a well seasoned pan.
1) Wash your with warm water and a wee bit of soap to start.
2). Dry it thoroughly over a flame or in the oven at 200 degrees to make sure it’s bone dry. This step also helps to open up the pores of the iron in preparation for accepting the oil for a great seasoning.
3) Take out the warm dry pan and drizzle a little flaxseed oil into it. Rub it everywhere around the pan, inside and out, don’t forget the handle too! After it’s been thoroughly oiled, wipe it ALL OFF with a new towel or cotton cloth until it looks dry again. The micro layer of oil is all you need to start. Honest ! The pan should not look wet or have any puddles / streaks of oil running down it anywhere. It will seem dry again, which is perfect.
4) Put your pan upside down into the oven, and turn the oven up to its highest baking temperature ( 450-500° F), allowing the cold pan to preheat with the oven.
5) Once your oven hits the pre-set temperature, start the timer for a 1 hour bake session, and TURN ON YOUR KITCHEN FAN. The seasoning process technically happens when the oil bakes above its smoke point, which polymerizes the first layer of oil on the surface of the pan.
6). After the first hour is up, let the pan cool naturally in the oven for 1 hour, then repeat the process a total of 6 times – yes, 6 TIMES ! This is the most ideal way to insure your pan will have the darkest, most even & hardest seasoning you’ve ever seen in an iron skillet!
Wood Fire / Open Flame Seasoning

Few things compare to the adventures one can have while traditionally seasoning your cast iron cookware. The open-flame process involves building a wood fire outside and rolling up your sleeves for a couple hours; perfect for the tool-heads & thrill seekers out there. We’re not going to lie, this method does require a little more grit & ambition than the oven seasoning approach. The good news is you can enjoy the fact that this process is about 6 times quicker than oven seasoning.
Carbon flames & the higher temperatures achieved by wood-fires, creates the perfect environment for the Flax seed oil to polymerize rapidly into the surface of the iron, achieving a profoundly rich and baked in series of seasoned layers in the most deep & effective way.
Before you start your wood fire, you’ll need to be prepared with a few articles of safety gear & tools to help you manage the hot iron in the fire. Be aware that the temperatures of the iron, oil and fire can scald, and creates smoke plumes that can be harmful to breath in. So we recommend using these following precautions for your comfort and safety during this process:
- A pair of thick leather welding gloves
- Safety glasses
- Respirator or particulate mask if you’re sensitive to oily smoke. Using a box fan to blow away smoke helps a lot.
- A grill rack for over the wood / charcoal fire, keeping things clean
- A second grill rack, extra pieces of dry wood or a stump to set the hot pan onto while you oil the pan cyclically within this process.
- A long metal hook ( metal coat hangers can work!) to pick up and handle the hot pan
- A spray bottle filled with the seasoning oil ( or HVLP gun if you have an air compressor and like using spray gun equipment. Buy a new gun for this material. Harbor Freight has a nice small option for under $12 ).
1. Build a fire up until you have a bed of red embers & a low, non-sooty flame. ( 30 min. ) This kind of fire is nearly smokeless & hot as all get out.
2. Set the clean iron over the fire & heat ‘till it turns “white-blue” in color. This means it’s ripping hot, and you’re now ready for the first coat of oil !
3. Hook the handle, pull the pan off the fire, & mist it evenly with the Flax Oil.
4. Not Too Much! You don’t want puddles, drips or thick coats. Just a very thin & even layer into every nook, cranny, handle & backside. The pan should be smoking fiercely when you do this. Stand down wind.
5. Put the smokin’ pan back onto the fire & let it smoke out until it stops. Watch for uneven heating & adjust the iron over the best heat spot on your fire.
6. You’ll know you are ready for the next layer of oil when you see the ash of the fire wisp off the face of the once sticky oiled surface. The color should be even, the first few coats have a brownish-red hue on them, & the pan will look dry again.
7. Repeat steps #2-#5 about 6 times ! You’ll see the pan turn to a rich “blue-black” by the last round of oil. (Approx. 1 hour of seasoning.) Enjoy the fire when you’re all done & marvel at your crafty work while letting your iron cool down naturally on a wire rack.
- Be very careful to not put the hot iron onto something wet or cold ! The dramatic difference of temperatures could cause a cast iron skillet to crack or warp from thermal shock!Your pan should be a deep black color and ready to use within one hour’s time of this open-fire process.
- If you find that the cookware is still a little sticky after it’s cool, you may need to oven bake it for 30-45 minutes, to finish it off and get it totally dry.If your pan develops of reddish color and you can’t seem to get it black, there’s three possible issues you’re facing:
- You probably don’t have enough heat on it
- You haven’t done the seasoning long enough
- You put the oil on too thick
