01 - Pat chicken thighs dry with paper towels. Rub evenly with salt, black pepper, smoked paprika, dried thyme, and oregano, ensuring all surfaces are coated.
02 - Heat olive oil in a large skillet over medium-high heat. Sear seasoned chicken for 2-3 minutes per side until golden brown. This step develops deeper flavor but can be skipped.
03 - Arrange carrots, celery, diced onion, minced garlic, and halved baby potatoes in an even layer at the bottom of the slow cooker insert.
04 - Place seared chicken pieces directly 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 internal temperature reaches 165°F and meat pulls away easily from the bone.
06 - Discard bay leaves. Taste the cooking liquid and adjust salt or pepper if desired. Add fresh lemon juice for brightness if using. Garnish generously with chopped parsley.
