While chicken bakes, toast almonds in a small baking pan in oven, stirring a few times, until golden, 8 to 10 minutes.
Meanwhile, cook apricot preserves, soy sauce, mustard, butter and remaining 1/4 teaspoon salt and 1/4 teaspoon pepper in a small saucepan over medium heat, stirring, until preserves are melted. Pour sauce over chicken and continue to bake until chicken is just cooked through, about 10 minutes longer.
Turn on broiler. Broil chicken 4 to 5 inches from heat, basting once, until chicken is glazed and browned in spots, about 3 minutes. Serve sprinkled with almonds.
