Cook 8 to 12 minutes, turning occasionally, until mushrooms are tender. Remove chicken and mushrooms from skillet; drain if necessary. Cover to keep warm.

Reduce heat to low; cover and cook 10 to 15 minutes or until sauce is thickened and juice of chicken is clear when thickest part is cut to bone (180°F).
