Tips
Do not overcook chicken; use a meat thermometer to verify internal temperature reaches 165F for food safety.
Halve mushrooms evenly for consistent cooking.
Keep chicken warm on a low oven setting while preparing the sauce to prevent it from cooling.
Good to Know
Refrigerate cooked chicken and mushrooms in an airtight container for up to 3 days.
Prepare marinade and marinate chicken up to 4 hours ahead. Cook just before serving for best texture.
Serve hot with crusty bread, rice, or roasted vegetables to soak up the balsamic sauce.
Common Mistakes
Do not skip coating chicken in marinade; this prevents drying and adds flavor.
Do not crowd the skillet; use medium-high heat to achieve proper browning.
Do not rush mushroom cooking; allowing them to brown deeply develops rich flavor.
