This roast is worth celebrating. Dried porcini mushrooms are blitzed to a powder with fresh rosemary sprigs, creating an umami-rich crust for beef. It's stand alone good, but when served with a port wine reduction infused with rosemary and porcini, it becomes an elegant dinner worthy of any holiday celebration. If you have the time, salt the meat well in advance. This will ensure juicy results and a crispy crust. I used a combination of port and red wine for the sauce. The red wine may be substituted with additional port.
Ingredients
1. 1
center-cut beef tenderloin, 3 pounds
2. Salt
3. 1
ounce dried porcini mushrooms
4. 2
tablespoons fresh rosemary leaves, finely chopped
5. 1
teaspoon black peppercorns
6. Olive oil
For the Port Wine Sauce:
1. 1/2
ounce dried porcini mushrooms, reconstituted in 3/4 cup water, liquid reserved
2. 3
tablespoons unsalted butter, divided
3. 1
medium shallot, finely chopped
4. 1
cup port wine
5. 1
cup heavy bodied red wine
6. 2
rosemary sprigs
7. 1/2 teaspoon salt, or to taste
Directions
Season the tenderloin all over with salt. Refrigerate 4
hours or up to 24 hours. Thirty minutes before roasting remove beef from
refrigerator.
Preheat oven to 400 F. Combine mushrooms, rosemary and
peppercorns in spice grinder. Grind to a coarse powder. Rub beef with olive
oil. Coat all over with porcini rosemary rub. (Note: Make sure your mushrooms
are completely dry and brittle, or they won't willingly grind into powder. If
they're at all pliant, you can dry them out in the oven until they break
easily.)
Heat 1 tablespoon olive oil in a wide skillet over
medium-high heat until shimmering. Add beef and brown on all sides, about 8
minutes. Transfer to a roasting pan. Roast in oven until thermometer inserted
in thickest part reads 125 F., about 30 minutes, for medium rare. Remove from
oven and transfer to a cutting board. Tent with foil and let stand for 15
minutes.
Carve beef in 1/4 inch slices. Serve with Port Wine Sauce.
For the Port Wine Sauce:
Strain the porcini water through an un-bleached paper towel
into a small bowl. Reserve strained liquid. Coarsely chop porcini.
Using the same skillet from browning the meat, add 1
tablespoon butter, shallots and chopped porcini. Sauté over medium heat until
shallots are translucent, about 2 minutes.
Add port wine, scraping up any brown bits in the pan. Add
red wine, mushroom stock and rosemary. Bring to a boil and cook uncovered until
sauce is reduced by about half to approximately 1 1/2 cups. Add salt and taste
for seasoning. Strain through a fine-meshed seive into a small saucepan,
pressing firmly on solids. Discard solids.
Heat sauce over medium heat. Whisk in 2 tablespoons butter,
1 tablespoon at a time. Keep warm until serving.
