Roast Chicken with Potatoes, Shallot, and Lemon

Preheat oven to 425°F. Pat chicken dry using paper towels. Place chicken, backbone side up, on a cutting board. Using kitchen shears, cut along each side of backbone; remove and discard backbone. Flip chicken breast side up, and push down on breast to flatten. Sprinkle chicken all over with 2 1/2 teaspoons salt and 1/2 teaspoon pepper. Set aside at room temperature for 30 minutes. (Alternatively, refrigerate, uncovered, on a wire rack set inside a baking sheet until skin is dried, at least 8 hours or up to 12 hours. Remove from refrigerator, and let come to room temperature, about 1 hour.)
In a 9- x 13-inch ceramic baking dish or braiser, toss together potatoes and shallots with 2 tablespoons olive oil, remaining 1 1/4 teaspoons salt, and remaining 1/2 teaspoon pepper. Add garlic and lemon halves, and toss until lightly coated in oil; arrange garlic cut side down in baking dish. Drizzle with wine, and top with tarragon sprigs.
Place chicken, breast side up, over mixture in center of baking dish; drizzle with remaining 2 tablespoons olive oil. Roast in preheated oven until potatoes are browned and very tender and a thermometer inserted in thickest portion of chicken registers 165°F, 55 minutes to 1 hour.
Remove from oven, and let chicken rest 10 minutes. Squeeze garlic cloves from skins into baking dish, and toss with potatoes. (Discard garlic skins.) Squeeze lemon halves over potatoes; discard lemons. Serve warm.
