Remove the giblets from the chicken cavity and pat the chicken dry with paper towels.
In a small bowl, mix together salt, pepper, garlic powder, onion powder, paprika, thyme, and rosemary.
Rub the chicken all over with olive oil, then evenly coat with the spice mixture, including under the skin if possible.
Place the chicken breast-side up in the crockpot. Pour chicken broth or water into the bottom of the crockpot around the chicken (do not pour over the top to keep skin crispy if desired).
Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the internal temperature reaches 165°F (74°C) in the thickest part of the thigh.
Let the chicken rest for 10 minutes before carving or shredding. Serve warm.
Notes
For extra flavor, add sliced onions, carrots, or potatoes to the crockpot before cooking.
