Braised Lamb Shanks with Caramelized Onions

Adapted from Bon Appetit.

• 4 tablespoons olive oil
• 1 pound onions, sliced
• 5 large shallots, sliced (about 1 cup)
• 2 tablespoons chopped fresh rosemary or 2 teaspoons dried
• 6 3/4- to 1-pound lamb shanks
• All-purpose flour
• 2 1/2 cups dry red wine
• 2 1/2 cups canned beef broth
• 1 1/2 tablespoons tomato paste
• 2 bay leaves

Heat 2 tablespoons olive oil in heavy, large Dutch oven over medium-high heat. Add sliced onions and shallots and sauté until brown, about 20 minutes. Mix in 2 tablespoons chopped rosemary. Remove from heat.

Sprinkle lamb shanks with salt and pepper; coat lamb with flour. Heat remaining 2 tablespoons olive oil in heavy, large skillet over high heat. Working in batches, add lamb shanks to skillet and cook until brown on both sides, about 10 minutes per batch. Using tongs, transfer lamb shanks to plate. Add 1 cup dry red wine to same skillet and bring to boil, scraping up any browned bits. Pour into Dutch oven with onion mixture. Add remaining 1 1/2 cups red wine, canned beef broth, tomato paste and 2 bay leaves to Dutch oven. Bring to boil, stirring until tomato paste dissolves. Add lamb shanks, turning to coat with liquid.

Bring mixture to boil. Reduce heat, cover and simmer until lamb is almost tender, turning lamb shanks occasionally, about 1 1/2 hours. (Can be prepared 1 day ahead. Cover and refrigerate.)

Uncover Dutch oven and boil until liquid is reduced to sauce consistency, stirring and turning lamb shanks occasionally, about 30 minutes. Season with salt and pepper. Serves 6.
