Ingredients Needed for Roasted Beef Tenderloin With Mushroom Sauce
1 pound beef tenderloin
3 tablespoons of olive oil
4 teaspoons of butter, at room temperature
3 rosemary sprigs
4 garlic cloves
7 ounces of mushroom, sliced
How to Cook Roasted Beef Tenderloin With Mushroom Sauce
- Tie the beef tenderloin using butcher twine as you can see in the video.
- Heat 2 tablespoons of olive oil in a skillet. Add 1 teaspoon of butter and let it melt on low heat. Lay the beef tenderloin in the skillet and fry it on all sides until it turns brown.
- Add the rosemary leaves (without sprigs) to a food processor. Also, add the garlic cloves, salt, and pepper. Pulse for a few seconds, add about 1 teaspoon of olive oil and pulse again until you make a coarse paste.
- Combine the rosemary paste with the remaining butter. Use half of this mixture to coat the fried beef tenderloin with it.
- Lay the meat in a baking pot and move to the oven. Roast for 15 minutes to 350˚F/175˚C. If you want it well-done, cook it a bit more.
- Meanwhile, add 2 tablespoons of olive oil to another skillet and start cooking the mushrooms. Add the remaining butter and rosemary mixture. When the mushrooms start to simmer, add the vegetable stock. Cook on low heat until you reduce the liquid.
- Slice the beef tenderloin and serve it with mushroom sauce.
