Bake for 45 to 50 minutes.
In a large skillet, melt 2 tablespoons butter over medium heat. Add mushrooms, garlic, and thyme; cook, stirring occasionally, until mushrooms are browned, 3 to 4 minutes. Add wine, and cook until almost evaporated. Add remaining 2 tablespoons butter, and cook until butter is melted. Remove from heat.
Divide arugula among 4 serving plates. Top with chicken, mushroom sauce, pomegranate seeds, and hazelnuts. Serve with carrots.
