Cranberry-Stuffed Cornish Game Hens

Preheat oven to 350 degrees. Spread out diced bread on a rimmed baking sheet; toastin oven, turning occasionally, until light brown and dry, 10 to 12 minutes. Set aside.

Raise oven temperature to 450 degrees. In a large nonstick skillet, heat the oil over medium-high heat until hot but not smoking. Add leek, mushrooms, garlic, and 1/2 teaspoon salt. Cook, stirring occasionally, until softened, about 2 minutes. Transfer to a bowl; stir in bread, chopped sage, parsley, mustard, thyme, 1/2 cup dried cranberries, and 1/2 cup broth.

Spoon stuffing into bird cavities; tie legs together with kitchen twine. Rub birds with butter, then sprinkle with pepper and remaining 1/2 teaspoon salt.

Arrange birds on a roasting rack in a large roasting pan. Roast until golden brown, about 30 minutes. Reduce oven temperature to 350 degrees, and continue roasting until an instant-read thermometer inserted into thickest part of thighs (avoiding bone) registers 170 degrees, 15 to 20 minutes more. Transfer rack with birds to a rimmed baking sheet, and let rest.

Set roasting pan on top of stove across two burners; set heat to medium-high. Add port and remaining 1/4 cup broth; deglaze pan, scraping up any browned bits from bottom with a wooden spoon. Add remaining 1/4 cup dried cranberries; cook, stirring, until sauce reduces slightly, 2 to 3 minutes.

Place birds on a serving platter, and drizzle sauce over them. Garnish with sage leaves, if desired, and serve.
