Tips

• Use chicken thighs for extra flavor and tenderness, though breasts also work well.
• Add the couscous at the end—cooking it too long will make it mushy.
• For a stronger lemon flavor, add extra zest just before serving.
• If the soup thickens as it cools, stir in a splash of broth or water when reheating.
• Taste before serving—lemon can balance saltiness, so adjust as needed.
