French Onion Soup

French Onion Soup

I love a good French onion soup, especially in the Fall when you can get really good, sweet onions. This French Onion Soup is way better than what I have had at most restaurants. The rich flavor paired with the gooey cheese and soft bread is just so… mmmmm.. there are no words that can describe how good it is.  Just as a little added note… when making French onion soup you definitely want to use beef consomme. You will find it adds a good depth of flavor that beef broth alone just can’t provide. You can find beef consomme in the canned soup isle in your grocery store. It is usually right next to the beef broth.

Save Recipe


  • 1/2 c. butter (1 stick)
  • 4 medium-sized sweet onions, sliced thin
  • 2 cloves garlic, minced
  • 2 sprigs fresh thyme
  • 1 bay leaf
  • 1/2 tsp. Kosher salt
  • ground black pepper, to taste
  • 3 (10.5 oz) cans Beef Consomme (found with the canned soups at the store)
  • 1 (10.5 oz) can Beef Broth
  • 1 Tbsp. red wine vinegar
  • 4 thick slices French Bread (OR 2 c. Parmesan croutons)
  • 4 slices provolone cheese
  • 4 slices Swiss cheese, chopped
  • Parmesan cheese, to taste
  • paprika, to taste


  • Melt butter in a stock pot. Add onions, garlic, thyme, bay leaf, salt and pepper.
  • Cook, stirring often, until onions are soft and caramelized (about 30 minutes).
  • Add consomme, beef broth, and vinegar and simmer another 30 minutes (at this point you can also transfer to a crock pot and cook on low heat for several hours).
  • When ready to eat, toast French bread in broiler for about 2 minutes turning once, until lightly toasted on each side. Remove from broiler, but keep broiler on.
  • Remove and discard bay leaf and thyme from soup. Ladle soup evenly into 4 oven-safe serving bowls. Place a slice of French bread into each bowl and top with provolone and Swiss cheese.
  • Sprinkle Parmesan cheese and paprika over the top and broil for about 5 minutes or until cheese is bubbly and golden brown.

    I typically just skim the broiled cheese off the top but this I know I would devour!! =)

    Great recipe easy to follow, turned out perfect thanks

  3. Brenda M says:

    I made this when I cooked in a restaurant but we used only about 2 tbsp of butter.. 1/2 cup it would swim in grease as there is also fat coming off of the cheeses. We also added about 2 cups of bar brand sherry for a large pot so I would think at least 1/4 cup for this size of recipe.

    I love French onion soup and home made would be excellent. I have a question, what consommé do you use? Is it 3 cans of undiluted concentrate or do you dilute as per the directions on the cans?

    • Erica says:

      UNdiluted for sure– don’t follow the directions on the can. We use beef consomme. Hope this helps!

  5. Judi Van Swieten says:

    Would like the nutritional breakdown, as I think this might be quite high in sodium, with salt, canned soup and cheese. Sure hope it falls in the acceptable range as it sounds delish.

    • Erica says:

      I don’t have that information but you can plug this information into a source like if you needed to find out!

  6. Ray says:

    This recipe looks amazing. I live in an apartment with a low end stove. A lot of recepies I have wanted to make lately say to use broiler but we haven’t had much luck with it and it usually ends with the smoke detector going off. Any ideas on getting around this and would this recipe suffer without that step?

    • Erica says:

      My advice would be just to watch it VERY closely. As soon as it starts to bubble, take it out. You could probably use a kitchen-torch if you have one!

    If you can get broth from cooking a roast it is extra fantastic. And as crazy as it may sound, adding a few dashes of balsalmic vinegar before dishing it out, the flavors are intensified!

    • Erica says:

      Great idea! Thank you for sharing! Will definitely try that next time I make a roast. YUM!

    My daughter made this and it was sooo good… I’m craving more….

  9. katie says:

    How many people does this serve? I have a family of four (the men usually go in for seconds) and I’m trying to decide if I need to double up on this recipe.

    • Erica says:

      It makes 4 good-sized bowls… if it is your main course doubling-up might not be a bad idea.

    I made this but it was extremely salty. I don’t have any experience cooking with beef broth or consomme. Afterward I Googled “what is the best beef broth” and the answer is the best broth is when you make it from scratch! But second best option is Better Than Bouillon – a jar of concentrated bouillon paste to which you add boiling water to make beef, chicken, or vegetable broth. Google results said that all canned beef broth is too salty – I had used Campbell’s beef consomme and Swanson’s beef broth. Google also told me that French Onion Soup can be made with chicken broth or plain water, so I bought the low sodium Better Than Bouillon chicken broth jar. I spooned out and strained the onions from my existing soup and discarded the salty beef broth/consomme, then prepped the Better Than Bouillon chicken broth and added my existing cooked onions. The results were much better for me than using the canned beef broth/consomme.

    Do you have any suggestions on how to make a vegetarian version of this soup?

    • Erica says:

      Hmm good question. You could try using vegetable broth but it probably won’t taste quite as good ;/ let us know if you try it and how it turns out!

  12. Shirley says:

    Can it just be made in the crock pot , or do you have a recipe for the crock pot ??

    • Erica says:

      Yes, this can easily be made in the crock pot 🙂
