Preheat oven to 350°F.
Place the All-Clad 3 Qt. Sauce Pan over medium high heat. Add the barley and stir for about 5 minutes or until the barley is lightly toasted and fragrant. Add the butter; when it melts, add the onions and bay leaf. Sweat the onions until they are soft, then add the mushrooms, dried porcini mushrooms, and stock.
Bring the liquid to a boil then cover the pot and place it in the center of the oven.
Bake the pilaf for 50 minutes, then remove from the oven and let the pot sit covered and undisturbed for 10 minutes.
Use a fork to fluff the pilaf, incorporating the minced chives. Serve.
