Beef Eye Fillet Steak (Lean) Correct Weight beef steaks are lean and super healthy. Here’s some tips to help you cook yours just right. Take it out of the fridge and let it sit at room temperature for about 30 minutes before cooking. Coat both sides of the steak with a little olive or grapeseed oil. This will seal the surface and means you need little or no oil on the pan or BBQ plate. The rule of thumb for cooking is 3 minutes per side on a hot pan, but it can vary and there are ways to test for doneness. Chef Adrian Richardson has some good advice. Let it rest. Once you take the steak off the heat, instantly wrap it in foil and let it sit for 3 minutes.
