01 - Pat chicken thighs dry with paper towels. Rub evenly with salt, black pepper, smoked paprika, dried thyme, and dried oregano, coating all pieces thoroughly.
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 enhances flavor but can be skipped for convenience.
03 - Layer sliced carrots, celery, diced onions, minced garlic, and halved baby potatoes evenly across the bottom of the slow cooker insert.
04 - Arrange seared chicken pieces on top of the vegetable bed. Pour chicken broth over everything, ensuring even distribution. Tuck bay leaves into the liquid.
05 - Cover with lid and cook on LOW setting for 6 hours. Chicken is done when internal temperature reaches 165°F and meat falls easily from the bone.
06 - Remove and discard bay leaves. Taste sauce and adjust salt and pepper if desired. Add fresh lemon juice for brightness if using. Garnish generously with chopped fresh parsley.
