1. In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Season the chicken thighs and drumsticks with salt and pepper, then brown them on both sides, about 5 minutes per side. Remove the chicken from the skillet and set aside.
2. In the same skillet, add the remaining olive oil and sauté the onions and garlic until they are translucent, about 3-4 minutes.
3. Add the mushrooms to the skillet and cook until they are golden brown, about 5 minutes.
4. Deglaze the skillet with white wine, scraping up any browned bits from the bottom. Allow the wine to reduce slightly, about 5 minutes.
5. Return the chicken to the skillet and add the chicken soup. Bring the mixture to a simmer, then cover and cook on low heat for 1 hour until the chicken is tender and cooked through.
6. In a separate saucepan, bring chicken soup to a simmer. Keep warm.
7. In a separate large saucepan, heat 1 tablespoon of olive oil over medium heat. Add the Arborio rice and cook, stirring constantly, for 2 minutes until the rice is lightly toasted.
8. Begin adding the warm chicken soup, one ladle at a time, stirring constantly and allowing the liquid to be absorbed before adding more. Continue this process until the rice is creamy and cooked al dente, about 20-25 minutes.
9. Season the risotto with salt and pepper to taste.
10. Serve the creamy mushroom risotto in a bowl, topped with the coq au vin blanc chicken pieces. Garnish with fresh parsley.
