Rich French Onion Soup

When entertaining guests, I bring out this savory soup while we're waiting for the main course. It's simple to make—just saute the onions early in the day and let the soup simmer until dinner-time. In winter, big bowls of it make a warming supper with a salad and biscuits. —Linda Adolph, Edmonton, Alberta

  • Makes
    10 servings

Ingredients

  • 6 large onions, chopped
  • 1/2 cup butter
  • 6 cans (10-1/2 ounces each) condensed beef broth, undiluted
  • 1-1/2 teaspoons Worcestershire sauce
  • 3 bay leaves
  • 10 slices French bread, toasted
  • Shredded Parmesan and shredded part-skim mozzarella cheese

Directions

  • In a large skillet, saute onions in butter until crisp-tender. Transfer to a 5-qt. slow cooker. Add the broth, Worcestershire sauce and bay leaves.
  • Cover and cook on low for 5-7 hours or until the onions are tender. Discard bay leaves.
  • Ladle soup into ovenproof bowls. Top each with a slice of toast; sprinkle with desired amount of cheese. Place bowls on a baking sheet. Broil for 2-3 minutes or until cheese is lightly golden.

Test Kitchen Tips
  • To give this dish a fragrant, unexpected quality, toss a couple of fresh thyme stems (or 1/4 teaspoon dried thyme) into your slow cooker. Discard stems before serving.
  • No time for chopping onions? Sliced onions work as well.
  • Soups can be brightened up before serving by adding a little citrus juce or vinegar. A teaspoon or two of cider vinegar tastes great in this soup.

      The most bland soup I’ve ever encountered. No way this recipe won a contest. We LOVE French Onion soup and I’m always looking to find the best recipe. This , sadly, is not it. Don’t waste your time.

      I added about 1/2 cup of red wine and extra Worcestershire and 2 cloves of minced garlic.

      I found this soup to be very tasteless. Maybe if the onion had been super caramelized as another reviewer suggested that would've helped. I even added 3 extra beef boullion cubes to the mix after tasting. It still needed something so I tried a touch of thyme and a couple of tsp of cider vinegar but neither of those did much either. Onions really burn my eyes so this was a double disappointment after the burning eyes from the onions. Will try another recipe as Jason's Deli has removed their onion soup from their line-up and it was so good!

      Boring, bland, flavorless. Used regular beef broth, not reduced sodium but it was still so blah. Won't make this again.

      This is an excellent recipe for French onion soup. I have made it as written and it is great. I have also followed another reviewers advice and carmelized the onions in the crockpot overnight and finished it the next day with a bit of red wine. Delicious!

      To the people complaining it's not vegetarian, use Vegetable broth!

      I also carmelized the onions. I made the rest of the recipe as stated and it will now be my "go to" recipe.
