French Onion Chicken Skillet with Melted Swiss

French onion soup's best feature — those slow-caramelized onions — gets borrowed here and turned into a skillet dinner. The onions cook low and slow until deeply golden, chicken breasts sear alongside them, and a splash of beef broth and thyme pulls it all together into a savory pan sauce, finished with melted Swiss.

Skipping the bread and heavy cheese layer that a traditional French onion soup usually carries keeps this dish lighter and lower in carbs, while the chicken keeps it filling enough to stand on its own as dinner.

Give the onions the full 20 minutes they need — rushing this step is the one thing that will shortchange the flavor.
