Pat the chicken dry with paper towels.
1 (4-pound) whole chicken
In a small bowl, stir the olive oil, 1 teaspoon salt, paprika, ½ teaspoon pepper, chopped thyme, and chopped rosemary together. Spread this mixture evenly over the chicken.
1½ tablespoons olive oil, 2 teaspoons kosher salt, 1½ teaspoons ground paprika, 1 teaspoon ground black pepper, 1 teaspoon chopped fresh thyme, 1 teaspoon chopped fresh rosemary
Spray the slow cooker with nonstick spray. Add in the celery, carrots, onion, sprigs of rosemary and thyme, and remaining salt and pepper. Stir to combine.
4 ribs celery, 3 carrots, 1 onion, 4 sprigs fresh rosemary, 4 sprigs fresh thyme
Place the chicken, breast side up, over the top of the veggies, cover and cook on high for 4-5 hours.
Carefully transfer the chicken to a parchment lined baking sheet and brush the skin with oil. Broil until the skin is crisp, about 3-5 minutes. Serve alongside the veggies.
