Instructions
Remove the tenderloin from the fridge and any packaging and leave at room temperature for 1 hour.
Preheat oven to 425°F/220°C.
Set a rack inside a baking sheet.
To a bowl add the softened butter and Dijon, mix well. Rub this mix all over the tenderloin.
To a small bowl add the salt, pepper, rosemary, sage and thyme, mix well.
Sprinkle the spice mix evenly all over the tenderloin, pressing it into the mustard.
Place the tenderloin onto the rack and roast for 30 minutes. Turn the temperature down to 350°F/177°C and cook until internal temperature reaches 130-135°F/55-58°C for medium rare, 140-145 °F/60-63°C for medium, 150-155°F/65-68°C for medium well.
Allow to rest for at least 30 minutes after removing from the oven before slicing. Serve with my Creamy Horseradish Sauce.
