Method

Step-by-Step Instructions

In a large pot over medium heat, melt 4 tablespoons of unsalted butter. Add 4 large, sliced yellow onions, stirring frequently for about 45–60 minutes until they turn deeply golden brown.
Once the onions are perfectly caramelized, sprinkle in 2 tablespoons of all-purpose flour, stirring continuously for 1–2 minutes.
Pour in 1 cup of dry white wine, and season with 1 teaspoon of kosher salt. Simmer for 1–2 minutes.
Add 4 cups of low-sodium beef stock and 2 cups of low-sodium chicken stock along with 2-3 sprigs of fresh thyme. Bring to a boil, then reduce the heat to low and let it simmer gently for about 15 minutes.
Ladle the hot soup into oven-safe ramekins and top each bowl with slices of a crispy baguette.
Generously sprinkle finely shredded Gruyère cheese over the baguette slices and broil in the oven for about 1–2 minutes or until the cheese is bubbling and golden.
