Set a rack 6 inches from heat source and preheat broiler to high. Season chicken on all sides with salt and pepper.
Melt butter with oil over medium-high heat in a large ovenproof skillet. Add chicken and cook until lightly browned, about 4 minutes per side.
Combine marmalade, mustard and lemon juice in a small bowl. Stir until blended.
Pour off fat from skillet. Add marmalade mixture and turn chicken several times to coat. Place skillet in oven and broil chicken until glazed and cooked through, about 10 minutes. Turn often, watching so it doesn't scorch.
