01 - Pat chicken thighs dry and rub with salt, pepper, smoked paprika, thyme, and oregano, ensuring even coverage on all pieces.
02 - Heat olive oil in a large skillet over medium-high heat. Sear seasoned chicken 2-3 minutes per side until golden brown, building deep flavor through caramelization.
03 - Arrange carrots, celery, onions, garlic, and potatoes in an even layer at the bottom of the slow cooker, creating a bed for the chicken.
04 - Place seared chicken on top of vegetables. Pour chicken broth over everything and tuck bay leaves into the liquid.
05 - Cover and cook on LOW setting for 6 hours until chicken reaches internal temperature of 165°F and meat is tender.
06 - Discard bay leaves. Adjust seasoning with salt and pepper if needed. Squeeze lemon juice over chicken for brightness and garnish with fresh parsley.
