I'm trying to figure out how to properly season my cast iron pans. What temp and how long do I need to bake the oil for it to like turn into that protective coating?
 
To get a great finish, heat your oven to 450–500°F for an hour. Then, spread a thin coat of flaxseed, grapeseed, or canola oil, and wipe off any extra. Bake it, let it cool, and do this 3–4 times to build up a good base. The high heat will help you get a smooth, strong finish.
 
@Jbocz the comment above is spot on, one more quick tip for the best results is to put your clean pan in the oven for about 10-15 minutes at a low temp (like 200°F) before you apply the oil.
This opens up the pores of the iron and gets rid of any last bit of moisture, ensuring the oil adheres better. It also helps the oil spread more easily and evenly.
 
To season a cast iron pan, first make sure it's thoroughly clean and dry. Then, apply a thin layer of cooking oil over the surface. Preheat the oven and place the pan upside down for about 1 hour. After baking, let it cool completely. Repeating this process 2–3 times will strengthen the non-stick coating, and applying a little oil during regular use helps keep it in great condition.
 
I just stick with what my grandma did.... wipe it down with lard or Crisco, 400°F for about an hour, then let it cool slow. Couple rounds of that and it's black as night and slick.
 
Coat the pan thinly with a high smoke point oil like flaxseed or canola, then bake upside down at 450 to about 500°F for about an hour. Let it cool in the oven before adding another layer and you'll see a few thin coats build up a solid, non stick surface over time
