Prepare the Vegetables: Wash and peel the carrots and parsnip. Chop into large chunks, along with the onion, to create a flavorful base. Layer at the bottom of the slow cooker.

Mix the Spice Blend: In a small bowl, combine paprika, garlic powder, onion powder, dried thyme, salt, and pepper. Stir until blended.

Prepare the Chicken: Remove giblets from the chicken cavity, rinse under cold water, and pat dry with paper towels.

Season the Chicken: Rub the spice mixture all over the chicken, including inside the cavity for even flavoring.

Place the Chicken in the Slow Cooker: Position the seasoned chicken on top of the vegetables, ensuring good balance.

Set the Cooking Time: Cook on low for 7-8 hours or on high for 3-4 hours for maximum tenderness.

Remove and Serve: Carefully lift the chicken from the slow cooker and let it rest for a few minutes before carving.
