Slice onions into thin rings. Place oil and onions in a sauté pan over medium heat. Add salt and sugar and caramelize onions, until golden, about 25 minutes. Add the Moscato or other wine and loosen up all the crispy bits. Remove onions and place them in a 9×13-inch baking pan or dish.

In the same pan, sear chicken steaks until richly colored. Add the steaks to the baking dish and season with additional salt and pepper.

Bake one hour, covered, in a 350-degree-Fahrenheit oven. Serve hot, smothering chicken steaks with onions.
