Provided by @MakeItYours

Number Of Ingredients 6

2 Tbs. extra-virgin olive oil
2 tsp. coarsely chopped fresh thyme
2 tsp. minced garlic
Kosher salt and freshly ground black pepper
4-lb. beef tenderloin roast, preferably from the thicker end, trimmed of silver skin and chain
1 recipe Double-Mushroom Ragoût

Steps:

Position a rack in the center of the oven and heat the oven to 250°F.
In a small bowl, combine the olive oil, thyme, garlic, 1 tsp. salt, and several generous grinds of black pepper. Put the tenderloin on a heavy-duty rimmed baking sheet or in a small roasting pan and rub the oil mixture all over it.
Roast the tenderloin until an instant-read thermometer inserted in the thickest part reads 130°F for medium rare, about 1 hour. Transfer to a carving board, tent with foil and let rest for at least 20 minutes before serving.
Cut the tenderloin crosswise into 1/2-inch slices. Serve with the ragoût.
Make Ahead Tips
You can season the tenderloin up to 6 hours ahead and refrigerate.
