100% Grass-Fed Australian Beef Tenderloin Filet Roast (1kg)

Great Southern


One cut of the tenderloin often referred to as the Chateaubriand - basically a gigantic filet steak. You can either cut the roast into smaller steak medallions (filet mignons) or cook the roast as is and then serve sliced. This is the ideal roast for special occasions and the holiday season, best suited for a gathering. The tenderloin is the most tender part of all beef cuts. If you are looking for fork-tender and lean roasts or steaks - choose tenderloin cuts. For roasting, you'll need an oven. First, season, then sear all sides in butter in the frying pan on very high heat, then wrap in aluminum foil and slowly roast in an oven at 180°C (‎350°F) for approx. 40 minutes until the internal temperature reaches 50°C (‎120°F). Or cut into smaller steaks and cook in the fry-pan or skillet. Everyone loves to have their own steak. Please note that this roast is cut from the whole tenderloin as is - it may have remaining tendon or fat that we recommend to remove before cooking. See the instructions below.

In our example we'll be cooking the roast in the oven, follow this: Tie the roast for a more even shape when roasting. Season with coarse sea salt and freshly ground black pepper. Optionally add garlic powder and dried thyme leaves to the roast. Prepare a skillet or a frying pan, add salt-free butter, and turn the heat to the hottest possible.

All we want to do is sear the outside of the roast before roasting it in the oven. So the frying pan or skillet needs to be extremely hot so that the outside becomes caramelized and crispy within seconds.
