Recipe from Culinary Director, Barcelona Wine Bar Restaurant Group (Washington, D.C.)

  • Prep: 15 mins
  • Cook: 2 hrs 45 mins
  • Yields: 10 to 12 Servings


1 Boneless leg of American Lamb (5 to 6 pounds)

¼ cup kosher salt

3 tbsp coarsely chopped fresh oregano

2 tbsp sumac

2 tbsp ground fennel seed

1 tbsp ground Pasilla chile, or other medium-hot chile such as ancho or mulato

1 tbsp freshly ground pepper

1 tbsp coarsely chopped fresh rosemary

2 tsp ground cinnamon

1 tsp ground cloves

⅓ cup extra virgin olive oil

Onion Gravy

1 cup drippings from roasting pan

1 cup thinly sliced onions

2 tbsp unsalted butter

1 tbsp all purpose flour

1 cup Rioja or other red wine

1 cup chicken stock

Potato Soufflé

3 lbs medium Yukon gold potatoes, washed, peeled, quartered

4 oz. (1 stick) unsalted butter, room temperature, cut in 8 to 10 pieces

½ cup all-purpose flour

8 large eggs

3 tbsp kosher salt

1 tsp freshly ground nutmeg


1Pat the lamb leg dry with paper towels; set aside.

2In a small bowl, combine salt, oregano, sumac, fennel, chile, pepper, rosemary, cinnamon and cloves; stir to combine. Add oil; stir to make a thick paste. Rub the paste over the entire lamb leg, making certain to coat all surfaces.

3Place the rub-coated lamb on a the rack of a roasting pan lined with foil. Refrigerate for 2 to 3 hours, or allow to sit at least 30 minutes at room temperature. Roast on the middle rack of oven at 450°F for 15 minutes. Reduce temperature to 325F; continue to roast until a meat thermometer inserted in the center of the roast registers 140°F for medium-rare. (Plan on 25 to 30 minutes per pound, or a total of approximately 2-1/2 hours for a 5 to 6 pound leg. Begin checking the temperature after 1-1/2 hours, to get a sense of how quickly the meat is cooking.)

4When it reaches 140°F, remove lamb from oven and pour 1/2 cup water in the bottom of the pan. Cover the lamb leg loosely with foil; let stand 15 to 20 minutes before slicing.

Onion Gravy

1In a medium-sized saucepan over medium-high heat, add pan drippings. When drippings and fat are hot, add onions; sauté onions until soft and caramelized, about 10 minutes. Add butter and flour; reduce heat to medium and cook stirring constantly for 3 minutes. Add wine; bring the mixture to a simmer. Reduce total volume of liquid by half; add chicken stock. Bring the mixture to a gentle simmer; cook until it has reduced slightly and thickened to the consistency of gravy.

Potato Soufflé

1Generously butter a round soufflé dish or casserole that is approximately 4 inches deep and 10 inches in diameter; set aside.

2In a large pot filled with cold water, add potatoes; season generously with salt. Bring water to a boil; reduce to a simmer and cook until potatoes are fork tender, about 15 minutes depending on size.

3Pour potatoes into a colander; shake to remove as much moisture as possible. Place potatoes in a food mill or potato ricer; add potatoes back to the pot with the butter, flour and nutmeg. Cook over low heat, stirring constantly with a wooden spoon. The mixture should come together into a single, cohesive mass.

4Transfer the potato mixture to the bowl of a stand mixer fitted with the paddle attachment. Mix on low speed for about 30 seconds while the eggs are cracked into a liquid measure. Lightly whisk the eggs; slowly add to the potatoes with mixer running. Increase speed to medium when all eggs are added. Mix 1 minute or until the eggs are fully incorporated and the mixture is smooth.

5Scrape contents of the mixer bowl into the prepared baking dish; place on middle rack of oven. Bake until soufflé has nearly doubled in size and is golden brown, approximately 30 to 40 minutes. Serve immediately.
