01 - Pat chicken thighs dry with paper towels. Rub evenly with salt, black pepper, smoked paprika, dried thyme, and oregano, coating all surfaces.
02 - Heat olive oil in a large skillet over medium-high heat. Place seasoned chicken in the hot pan and sear for 2-3 minutes per side until golden brown. This step builds depth of flavor but can be skipped for convenience.
03 - Layer carrots, celery, diced onion, minced garlic, and halved baby potatoes in the bottom of the slow cooker insert.
04 - Arrange seared chicken pieces on top of the vegetable bed. Pour chicken broth evenly over everything. Tuck bay leaves into the liquid.
05 - Cover with lid and cook on LOW setting for 6 hours. Chicken is done when it reaches an internal temperature of 165°F and shreds easily with a fork.
06 - Discard bay leaves. Taste the cooking liquid and adjust salt or pepper if needed. If desired, squeeze fresh lemon juice over the chicken for brightness. Sprinkle with chopped parsley and serve hot.
