Remove the Scotch Fillet steaks from the refrigerator 30 minutes before cooking and allow them to come to room temperature.
Preheat the oven to 120°C.
Pat the steaks dry with paper towel and season generously with salt and pepper on all sides.
Place the steaks on a wire rack over a baking tray and cook in the oven for 30–40 minutes, or until the internal temperature reaches approximately 48–50°C for medium rare.
While the steaks are cooking, combine the softened butter, garlic, parsley, rosemary and thyme in a small bowl. Mix well and set aside.
Heat a heavy-based frying pan or cast iron skillet over high heat until very hot.
Add the olive oil and sear the steaks for 60–90 seconds per side until a deep golden crust develops.
Remove the steaks from the pan and top each steak with a generous spoonful of garlic herb butter.
Rest for 5–10 minutes before slicing and serving.
