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, combine the olive oil, lemon juice, dried thyme, dried rosemary, paprika, salt, and pepper. Rub the mixture evenly over each chicken thigh, coating all sides.
03 - 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 seasoned chicken.
04 - 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.
05 - About 45 minutes before the cooking time finishes, spread the trimmed green beans on top of the chicken. Re-cover and continue cooking until the green beans are tender-crisp.
06 - Serve directly from the slow cooker, spooning the accumulated juices over the chicken and vegetables.
