How to make beef tenderloin with mushroom sauce

1. Cook the beef: Cut any excess fat or silverskin off the whole tenderloin. Slice into medallions (or have your butcher do it for you) with a sharp knife. Drizzle each steak with olive oil and season generously with salt, pepper and fresh thyme. Heat a large, deep pan or skillet over high heat and add the meat. Allow the steak to sear in the hot pan. Cook beef tenderloin to your preference. I like it medium-rare so I cook it 4-5 minutes per side until a deep brown crust forms. If you prefer a medium steak, cook for 5-6 minutes per side. Remove from the pan and place on a plate to rest while you make the sauce.
2. Make the truffled mushroom sauce: In the same pan you cooked the meat, melt a few tablespoons of butter then add the mushrooms, garlic and thyme. Cook over medium heat until the mushrooms are golden brown then pour in the cream, lemon juice and truffle oil. Season with salt and pepper. Simmer for a few minutes until the sauce coats the back of a spoon. Add the steaks back into the pan along with any resting juices. Cook for another 2-3 minutes to warm the steaks through then serve.

How long to cook beef fillet

For a more precisely cooked steak, use a meat thermometer and insert it into the thickest part of the meat to take the internal temperature.

• Medium rare: 57ºC/135ºF.
• For Medium: 63ºC/145ºF.
• Medium well: 66°C/150°F. If you prefer medium-well or well-done meat, I would suggest placing the meat in the oven to cook for a few minutes. This will prevent the meat from burning on the stove and will roast beef tenderloin to your preferred doneness.
• Well done: 71°C/160°F.
