Use 1 Tbsp or so of vegetable oil, ideally in a cast iron pan. Turn to medium - medium high heat.

Put the steak in the pan and cook on one side for 2 minutes. Add butter and any aromatics or additional spices – e.g. garlic, fresh herbs.

Put in a pre-heated 300F oven for about 10min for medium - rare.

Let rest, then slice and finish with some more salt.
