Sausages in Red Wine Sauce

• FAST

Ingredients

1. 2 tablespoons olive oil
2. 3 large shallots, thinly sliced
3. 2 1/4 cups full-bodied red wine
4. 1/2 cup chicken stock or canned low-sodium broth
5. 1 1/2 pounds assorted French- and German-style sausages
6. 2 cups water
7. 5 tablespoons cold unsalted butter, cut into tablespoons
8. Salt and freshly ground pepper
9. Potato Gratin

1. Heat 1 tablespoon of the olive oil in a medium saucepan. Add the shallots and cook until softened, 3 to 5 minutes. Add the wine and boil until reduced by half, about 10 minutes. Add the chicken stock and boil until reduced by one-third.
2. Meanwhile, in a medium enameled cast-iron casserole, heat the remaining 1 tablespoon of olive oil. Add the sausages and cook over moderately high heat until browned, about 3 minutes per side. Add the water and bring to a boil. Reduce the heat to low, cover and simmer until the sausages are cooked through, about 20 minutes.
3. Bring the wine sauce to a boil. Remove from the heat and whisk in the butter, 1 piece at a time. Season with salt and pepper. Cut the sausages into 2-inch pieces and arrange an assortment on each plate. Top with the sauce and serve with the Potato Gratin.
