Step 1

Bring roast to room temperature by taking it out of the fridge 1 to 2 hours before you prepare it.

Preheat oven to 450°F.

With a paring knife, poke holes every few inches throughout the roast. Push a garlic sliver into each hole.

Put dried mushrooms in a food processor or blender and whirl until mushrooms are ground into a fine powder. Mix mushroom powder, salt and pepper together. Rub the entire surface of the roast with the mixture.

Place roast in a roasting rack set inside of a roasting pan. Roast 20 minutes. Turn heat down to 350°F and roast until a thermometer stuck in the middle of the roast reads 120°F, 1 1/2 to 2 more hours.

Put the roast on a platter while it rests and collects its juices. After 30 minutes, the internal temperature of the roast should should be about 140°F, or medium rare. Transfer to a carving board. Cut the strings from your roast and slice.
