In a large skillet, heat olive oil over medium-high heat. Cook boneless skinless chicken breasts for 2 minutes on each side, just until they start to turn golden brown. Place chicken in 6-qt slow cooker.
Sprinkle chicken with Italian dressing mix. Add fresh garlic, butter, capers, fresh lemon juice and chicken broth.
Cover the crock pot and cook on low heat for 6 hours.
