Ingredients
Method
- Melt the butter in a heavy pot and caramelize the sliced onions over medium-low heat for 25 to 30 minutes minimum, stirring often.
- Stir in the flour and cook 1 to 2 minutes.
- Add the wine to deglaze if using, then gradually add the beef broth and simmer 15 minutes.
- Ladle into oven-safe bowls, top each with a slice of baguette and a generous handful of cheese.
- Broil until the cheese is bubbling and browned, watching closely so it does not burn.
Notes
Caramelization takes patience - rushing it on high heat makes the onions bitter, not sweet. Applebee's uses Gruyere or a Swiss Gruyere blend; Swiss alone is a budget swap with less depth. The optional wine adds acidity to balance the sweetness, and without it the soup can taste flat. Oven-safe bowls are a must and broiling goes from melted to burnt fast.
