It all depends on how rare or well done you like your steak.

If I were cooking a ribeye steak I would not add any oil to the pan at all as there is plenty of fat in the meat already which will render out.

You can rub a little oil on the steak before adding to the pan.

Put a good amount salt and pepper on the steak 5 mins before cooking.

The pan needs to be as hot as you can get it before adding the steak.

The higher the heat the better the crust on the outside.

Your steaks are quite thick, so for a medium rare steak you will need to cook them for about 4 minutes a side.

For a well done steak your talking 8 or 9 minutes a side.

Also cooking one steak at a time will improve results.

After cooking the steak will need to rest for about 4 or five minutes before serving.
