01 - Arrange the halved baby potatoes in an even layer across the bottom of the slow cooker. Scatter the sliced onion and minced garlic over the potatoes.
02 - In a small bowl, whisk together the olive oil, lemon juice, dried thyme, dried rosemary, paprika, salt, and pepper to form a cohesive marinade.
03 - Rub the herb marinade mixture thoroughly over each chicken thigh, ensuring even coverage on all sides.
04 - Place the seasoned chicken thighs on top of the layered vegetables. Pour the chicken broth around the base of the chicken and vegetables, avoiding pouring directly over the seasoned chicken.
05 - Cover the slow cooker and cook on the low setting for 6 hours, or until the chicken registers an internal temperature of 165°F and the potatoes are fork-tender.
06 - Approximately 45 minutes before the end of the cooking time, arrange the trimmed green beans on top of the chicken. Re-cover and continue cooking until the green beans are just tender-crisp.
07 - Serve directly from the slow cooker, spooning the accumulated cooking juices over the chicken and vegetables for added flavor.
