Method
Roast the beef
- Preheat the oven to 425°F.
- Pat the tenderloin dry, then rub it all over with the olive oil, garlic, rosemary, thyme, salt, and pepper.
- Set a rack in a 16x12-inch roasting pan and place the tenderloin on the rack; roast for 40–55 minutes, until a meat thermometer inserted into the thickest part reads 145°F.
- Transfer the roast to a cutting board, tent loosely with foil, and rest for 10 minutes.
Make the shallot sauce
- While the roast rests, melt 1 tablespoon of the butter in a 2-quart saucepan over medium heat; add the shallots and cook for 3–4 minutes, stirring, until softened.
- Add the red wine and bring to a boil; cook for 5–7 minutes, until reduced by about half.
- Stir in the beef broth and Dijon mustard; simmer for 8–12 minutes, until the sauce is slightly reduced and lightly coats a spoon.
- Remove the saucepan from the heat and whisk in the remaining 2 tablespoons cold butter until smooth; slice the rested roast and serve with the sauce.
Notes
Use a meat thermometer in the thickest part to check for 145°F. Refrigerate leftovers for 3–4 days; freeze for up to 3 months. For an alcohol-free sauce, replace the red wine with additional beef broth.
