Mix the garlic and thyme with the olive oil and rub the rack with the mixture. Place in the oven at 80°C (176°F) and cook for 60-90 minutes to 54°C (129°F) core temperature.
Sauté the mushrooms in butter and add the onion for the last minute. Deglaze with soy sauce and stock, reduce and add to the gravy. Season with pepper and salt.
