Cooking instructions
To cook Chateaubriand, preheat your oven to 220°C. Season a 600g beef fillet with salt and pepper. Heat a heavy-based pan with a splash of oil and sear the fillet on all sides until browned. Transfer to a roasting tray and cook in the oven for 15-20 minutes for medium-rare. Rest the meat for 10 minutes, covered with foil. Meanwhile, deglaze the pan with a splash of red wine, add beef stock, and reduce to make a sauce. Slice the Chateaubriand and serve with the sauce, roasted vegetables, and potatoes for an elegant and tender meal.
