Roasted Stuffed Chicken Thighs with Capers

Ingredients

1. 5 skinless, boneless chicken thighs (about 2 pounds)
2. Salt and freshly ground pepper
3. 2 tablespoons unsalted butter
4. 2 tablespoons olive oil
5. 1 small red onion, minced
6. 2 garlic cloves, minced with 1 teaspoon salt
7. 1 egg white
8. 1/2 cup fresh bread crumbs
9. 3 tablespoons finely chopped flat-leaf parsley
10. 3 tablespoons drained capers

1. Preheat the oven to 425°. Season 4 of the chicken thighs with salt and pepper and lay them boned-side up on a plate.
2. In a small skillet, melt 1 tablespoon of the butter in 1 tablespoon of the olive oil over moderate heat. Add the onion and cook, stirring frequently, until translucent, about 5 minutes. Add the garlic and cook, stirring, for 1 minute.
3. Cut the remaining chicken thigh into 1/2-inch pieces and transfer to a mini food processor. Add the egg white and pulse 12 to 15 times, until the chicken begins to form a ball. Scrape into a small bowl and add the sautéed onion and garlic and the bread crumbs and parsley; mix well.
4. Using lightly moistened hands, spread one fourth of the stuffing on each seasoned chicken thigh to within 1/2 inch of the edge of the meat. Gently roll up the thighs; the stuffing should hold the rolls together.
5. In a medium, nonstick, ovenproof skillet, melt the remaining 1 tablespoon of butter in the remaining 1 tablespoon of olive oil over moderate heat. Add the stuffed chicken thighs, cover and cook until well-browned on the bottom, about 5 minutes. Turn the thighs and cook until browned on the second side, about 2 minutes longer. Sprinkle the capers around the chicken and roast uncovered for 15 to 20 minutes, until a thermometer inserted in the center of the thighs registers 150°. Transfer the chicken and capers to plates and serve.
