Ingredients

1 whole fryer chicken, quartered, rinsed, and patted dry 

Coarse salt and freshly ground pepper 

2 tablespoons olive oil 

1 tablespoon unsalted butter 

4 leeks, white and light-green parts only, halved lengthwise and then sliced into 1-inch pieces, washed well, and dried 

1/3 cup chopped fresh tarragon, plus more sprigs for garnish 

1/2 cup dry white wine 

2 1/2 cups homemade or low-sodium canned chicken stock 

1 tablespoon freshly grated lemon zest 

1 teaspoon freshly squeezed lemon juice 

Preparation

Season chicken with salt and pepper. Heat oil and butter in a large skillet over medium heat. Add chicken, skin side down; cook until skin is browned, about 5 minutes. Turn, and cook until other side is browned, about 3 minutes. Transfer to a plate; set aside.

Add leeks to skillet; cook until soft, about 3 minutes. Add tarragon; cook 1 minute. Add wine; deglaze pan, scraping up any browned bits from bottom, until liquid evaporates. Add stock and zest. Cover; bring to a boil. Return chicken to skillet; simmer, covered, over medium-low heat until cooked through, 35 to 40 minutes.

Transfer chicken to a platter; keep warm. Place skillet over high heat; cook until sauce thickens, 5 to 6 minutes. Stir in lemon juice. To serve, spoon sauce over chicken; garnish with tarragon sprigs.
