Step 1

For garlic butter, place all ingredients in a bowl and, using a fork, mash together until well combined. Season to taste and set aside.

Step 2

Cut a pocket in each steak from the widest end with a thin sharp knife. Fill each with 3 oysters and a generous amount of garlic butter and close up with a toothpick.

Step 3

Preheat oven to 180C. Heat oil in an ovenproof frying pan over high heat, add steaks and cook, turning often so they cook evenly, until brown (4-5 minutes). Transfer pan to oven and cook to your liking (8-10 minutes for medium). Remove from oven, rest for 5 minutes, then serve with steamed greens and potatoes.
