- 1/4 cup (2 ounces) sweet vermouth, sherry, or brandy
- 1/4 cup (2 ounces) dry white wine or Lillet Blanc; see notes
- 4 to 5 cups (950ml to 1180ml) chicken broth or beef stock, see tips
- 1 teaspoon fresh thyme leaves
- 1/4 teaspoon fine sea salt, plus more to taste
For Serving:
- 1 French baguette or rustic loaf, sliced into 1/2-inch slices, 12 slices
- 2 cloves garlic
- 1 cup (114g) grated Gruyere cheese, 4 ounces
Instructions
- Make Soup – Melt butter, caramelize onions, add vermouth, wine, broth, thyme, and salt. Simmer.
- To Serve – Toast bread, rub with garlic, dunk in soup. Top bread with cheese, ladle soup, and broil until cheese is bubbly and golden.
Notes
- Be cautious with sweet onions as they caramelize faster.
- Homemade chicken broth or beef stock is recommended over store-bought options.
- Substitute vermouth with sherry or brandy, and Lillet Blanc with dry white wine.
