cooking time for beef tenderloin in the oven
Preheat the oven to 475 degrees F. Place the tenderloin on a roasting rack. Sprinkle generously with kosher salt and sugar, which will deepen the savory flavors. Press the crushed peppercorns all over the surface of the meat.Insert a meat thermometer and place in the oven until the beef registers 120 to 125 degrees F for medium-rare/rare. Beef will probably cook in 20 to 25 minutes depending on its temp before it goes in the oven.While the meat is roasting, melt the butter with the garlic in a small skillet, and allow the butter to slightly brown.eef will probably cook in 20 to 25 minutes depending on its temp before it goes in the oven.
