Ingredients
  

  • ½ cup butter unsalted butter is fine
  • 2 pounds onion white or yellow cooking onions
  • 3 cloves garlic minced
  • 2 - 3 sprigs fresh thyme or 1/4 teaspoon dried
  • 2 bay leaves
  • ½ cup red wine
  • 3 cups chicken broth use low or no sodium added
  • 3 cups beef broth use low or no sodium added
  • 1 cup gruyere cheese shredded
  • baguette slices you need about 6 slices cut 1/2 inch thick
  • salt and pepper

Instructions
 

  • Melt the butter in a large pot over medium heat.
  • Add the onions and thyme, then reduce the heat to medium-low. Cook the onions slowly, stirring often, until they are soft and deeply golden. This will take 30-40 minutes.
  • Add the red wine, letting it simmer and reduce until only a thin layer remains at the bottom of the pot.
  • Pour in the beef and chicken broths, bring the soup to a gentle boil, then reduce the heat and simmer for 20 minutes.
  • Preheat the broiler in your oven.
  • Ladle the soup into oven-safe bowls, top with toasted baguette slices, and sprinkle generously with grated Gruyere cheese.
  • Broil until the cheese is bubbly and golden, keeping a close eye to avoid burning.
  • Serve hot and enjoy!

Notes

Chef Jenn's Tips:

  • Take your time caramelizing the onions—this is the key to deep flavor.
  • No fresh thyme? Substitute with ¼ teaspoon dried thyme.
  • If using sweet onions like Vidalia, keep in mind your soup will be sweeter.
  • Be careful not to over-salt. The cheese adds a salty finish, so season the soup lightly until after adding the cheese.
