01 - Arrange the halved baby potatoes in an even layer at 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 until well combined.
03 - Rub the herb marinade mixture thoroughly over all sides of each chicken thigh, ensuring even coating.
04 - Place the seasoned chicken thighs on top of the layered vegetables. Pour the chicken broth around the edges of the chicken and vegetables, avoiding pouring directly over the chicken to keep the seasoning intact.
05 - Cover the slow cooker and cook on the low setting for 6 hours, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
06 - About 45 minutes before the cooking time ends, spread the trimmed green beans evenly over the top of the chicken. Re-cover and continue cooking until the green beans are crisp-tender.
07 - Serve directly from the slow cooker, spooning the accumulated cooking juices over the chicken and vegetables for added flavor.
