01 - Pat chicken thighs dry with paper towels. Rub thoroughly with salt, black pepper, smoked paprika, dried thyme, and dried oregano, ensuring even coverage on all pieces.
02 - Heat olive oil in a large skillet over medium-high heat. Sear seasoned chicken on both sides for 2-3 minutes until golden brown. This step develops depth of flavor though remains optional.
03 - Layer sliced carrots, celery, diced onion, minced garlic, and halved baby potatoes evenly across the bottom of the slow cooker insert.
04 - Place seared chicken pieces directly atop the vegetable bed, arranging in a single layer for consistent heat distribution.
05 - Pour chicken broth uniformly over the chicken and vegetables. Tuck bay leaves into the liquid. Do not stir.
06 - Cover with lid. Cook on LOW setting for 6 hours until chicken reaches internal temperature of 165°F and vegetables are tender.
07 - Discard bay leaves. Taste broth and adjust seasoning with additional salt and pepper if desired. Add fresh lemon juice for brightness if using. Garnish generously with chopped parsley and serve hot.
