01 - Generously season chicken thighs on all sides with salt, pepper, paprika, dried thyme, and dried rosemary, ensuring even coating.
02 - Heat olive oil in a large skillet over medium-high heat. Add seasoned chicken thighs and sear for 2-3 minutes per side until golden brown. This step enhances depth of flavor but may be omitted for convenience.
03 - Place peeled carrot chunks, cubed potatoes, sliced onion, chopped celery, and minced garlic evenly across the bottom of the slow cooker insert.
04 - Arrange browned chicken thighs directly over the vegetable bed, positioning skin-side up if applicable.
05 - Pour low-sodium chicken broth over the chicken and vegetables, ensuring even distribution.
06 - Cover slow cooker with lid and cook on low setting for 6 hours, or until chicken reaches an internal temperature of 165°F and vegetables are fork-tender.
07 - Ladle hot chicken and vegetables into serving bowls. Garnish with chopped fresh parsley if desired. Serve immediately.
