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

  1. 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.
  2. Cover and cook on low for 5-7 hours or until the onions are tender. Discard bay leaves.
  3. 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. Yield: 10 servings.

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.
  • Make this soup meat-free by using condensed vegetable broth, apple cider or a combination. If you use only apple cider, remember it has no salt, so you'll have to adjust the seasonings.
  • 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.

    "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!

    "I cut it down because it is just two of us. I didn't chop the onions but sliced them then cut then slices in half. I liked the flavor of the onions. I like the flavor the Parmesan cheese gave to it as well."

    "I use the slow cooker to caramelize the onions first in the slow cooker, then do the rest of the recipe so it takes me a full day to do this soup. I put the onions on overnight, add the rest in the morning and prepare as above. Sometimes I add thyme also. I want to try the idea mentioned of using cider. I'll use apple juice instead since I always have it on hand and see how it is. Sounds really unique and tasty."

    "While I haven't made this specific recipe, I just wanted to mention that you can also use the "Better Than Bouillon" beef base instead of the canned soup (3 Tbsp. base to 8 cups water). They even make a low salt version although I just use the regular version and to us the salt level is perfect. I too caramelize the onions in butter with a little oil, 4 Tbsp. butter with 2 Tbsp. oil, in a large pot. Once caramelized, I sprinkle with 3 Tbsp. flour;stir, and then add the base/water to the pan. To make the soup on the stove top, after combining all the ingredients, bring to a boil and then lower to a simmer, partially covered, for 45 minutes before ladling it into the ovenproof bowls. We prefer Mozzarella only and my husband likes it when I put some of the shredded cheese in the bottom of the bowl before ladling in the soup, then the bread with lots of cheese on top and then under the broiler. You can also sprinkle with a little paprika if you wish for a little added color."

    "When I make French Onion soup, I use 2:1 ratio of beef broth to apple cider. It gives it a hint of flavor that people like...but can't figure out. Always fun to serve to guests."
