Recipe Ingredients

  • 6 tablespoons olive oil
  • 4 medium yellow onions, sliced 1/4 inch thick
  • 1 tablespoon unsalted butter
  • 1 clove garlic, thinly sliced
  • 4 sprigs fresh thyme
  • 1 bay leaf
  • salt to taste
  • ¼ teaspoon ground white pepper
  • ¾ cup dry white wine
  • 2 quarts chicken stock
  • ½ cup port wine
  • 6 slices French bread
  • 2 cups shredded Gruyere cheese

Cooking Directions

  1. 1 Heat the olive oil in a heavy pot over medium heat. Add the onions; cook and stir until golden brown, about 30 minutes.
  2. 2 Add butter, garlic, thyme, bay leaf, salt, and white pepper. Cook and stir for about 10 minutes. Increase the heat to high, and stir in the white wine. Bring to a boil, and cook until wine has reduced by half, 3 to 5 minutes. Pour in the chicken stock, and simmer over medium heat for 45 minutes.
  3. 3 Preheat the oven's broiler. Remove the thyme sprigs and bay leaf from the soup, and stir in the port wine. Ladle soup into 6 crocks or heat proof bowls, top each with a slice of bread, and a generous helping of Gruyere cheese. Place the bowls on a baking sheet for ease in handling.
  4. 4 Place under the broiler for 2 to 3 minutes, until the bread and cheese are toasted and bubbly. Serve immediately.

  1. Delicious soup! I've made it twice now. One time as called for with chicken stock and the other with beef stock. We preferred it with beef stock but it's good both ways. Also the second time we made it we added a little more port and it was sensational. Thanks for the recipe. Easy and - Read more ...
  2. A really good recipe and easy to make your own! I use a little less than 2 quarts stock to keep the flavor really rich.
  3. This was absolutely delicious. If you are looking for a rich beefy salty french onion STOP this is not your soup. This is light fresh and very delicious. Followed the directins to a "T". I used prepared croutons on top love getting that easy bite of bread with every bite. Thanks for an easy and - Read more ...
  4. This was amazing. I subbed beef stock for the chicken. Also used some sliced swiss in addition to the cheese called for. I didn't have any port so I subbed more of the white wine. I am a vegetarian but I made an exception for this soup since my grandpa requested it. I'll try it - Read more ...
  5. Excellent! I was a little worried about using chicken broth instead of beef but was really happy with the way this turned out. I used a combination of mozzerella and parmesan as I didn't have Gruyere. I also added a little fresh parsley. Thanks for the recipe!
  6. Good general recipe however I did not feel that chicken stock was appropriate for french onion soup. I used beef stock instead and also added a bit of sugar to the onions to help carmalize. Soup turned out very tasty and the family loved it. Thanks!
  7. This recipe was wonderful! I followed the directions and cook times exactly the only substitution was that I used 1 quart vegetable stock and 1 quart chicken stock which complimented the flavor I thought. I have never made any kind of soup before but since my bf and I both love French Onion soup and - Read more ...
  8. Absolutely delicious...worth the time. (It took me at least twice as long to cook the onions.) I loved the addition of bay and fresh thyme which I had not put into french onion soup before. It's worth splurging on a very good cheese for this recipe. On to the inevitable substitutions. I did not have - Read more ...
