Leave beef in room temperature for a few hours. Mix salt and pepper and rub meat all over with hands just before cook.
Put some oil on a frying pan and heat it up with over high heat. Pan fry the beef whole surface till to get grilled eyes.
Pan fried some fried garlic till golden colour, take out it from oil. Pour the oil on the beef for flavoring, and the garlic is going to be garnish later.
The temperature of oven is 220(428), warm oven first, then cook both sides 15 minute each.
30 minutes later, lower the temperature to 170(328). Every 20 minutes, turn over the beef to cook evenly, cook till the temperature reaches to 65 in the middle.
When it cooks, cover the beef with aluminum foil to keep juice inside the meat for 30 minutes. This is it !! Slice them and serve with your favorite sauce.
This time I prepared fried garlic, chopped green onion with ponzu sauce, special onion and mushroom sauce. I recommend it with wasabi !! my favorite
