Preheat the oven to 350°F. Add the chicken to a roasting dish and season with the salt, paprika, onion powder, garlic powder, oregano, and black pepper. Drizzle with olive oil, then toss well until evenly coated.
Scatter the onions and thyme around the chicken, then pour the bone broth into the pan. Avoid pouring it directly over the chicken so the seasonings stay on.
Cover and bake for 1 hour 30 minutes.
Remove the chicken from the oven and increase the temperature to 450°F. Discard the thyme sprigs, then lift the chicken out of the pan and set aside on a clean plate.
Add 1/4 cup of the broth from the pan to a small bowl or measuring cup along with the arrowroot and whisk until smooth to make a slurry. Whisk the slurry into the rest of the broth in the pan, then return the chicken and toss to coat evenly in the sauce.
Return the chicken to the oven uncovered for 20 minutes longer, basting every 5 minutes if you like, until golden brown and the gravy has thickened.
Serve over cooked white rice.
Low-and-slow baked bone-in chicken that falls apart tender, then tossed in a silky bone-broth gravy and served over rice. Gluten-free and dairy-free (arrowroot thickens the gravy). A cozy fall favorite from Caitlin Jesson. Via Instagram @caitlinjesson. https://instagram.com/reel/DeueGzZMZjE
