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 until well combined.
03 - Coat each chicken thigh thoroughly with the herb-oil mixture, rubbing it over and under the skin to ensure even coverage.
04 - Place the seasoned chicken thighs on top of the vegetable bed. Pour the chicken broth around the edges of the slow cooker, avoiding pouring directly over the chicken to keep the herb crust 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 - Approximately 45 minutes before the cook time ends, spread the trimmed green beans over the top of the chicken. Re-cover and continue cooking until the beans are crisp-tender.
07 - Spoon the accumulated cooking juices over the chicken and vegetables and serve directly from the slow cooker.
