1Place the chicken thighs in a large bowl with the sliced onion, 2 tablespoons thyme, chiles, bay leaves, and 1/4 cup vermouth. Using your hands, toss to coat the chicken well. Cover, and refrigerate at least 4 hours, preferably overnight.
2Place the breadcrumbs in a medium bowl. Heat a large sauté pan over medium heat for 1 minute. Add 3 tablespoons butter, and cook until it’s brown and smells nutty. Use a rubber spatula to scrape the brown butter over the breadcrumbs. Wait 1 minute, and then toss well with the parsley and 1 tablespoon thyme.
