French Onion Soup

French Onion Soup

The trick to a great French onion soup is starting with good stock. French onion soup is usually made with beef stock. I've made delicious soup with stock from the leftover rib and chine bones of a rib roast. Another important element is the proper caramelization of the onions. Caramelizing onions take at least thirty minutes of slow cooking the onions over medium high heat. The browning, or caramelizing, of the onions brings out the sweetness in them.

French Onion Soup Recipe

Ingredients

  • 6 large red or yellow onions, peeled and thinly sliced.
  • Olive oil
  • 1/4 teaspoon of sugar
  • 2 cloves garlic, minced
  • 8 cups of beef stock, chicken stock, or a combination of the two (traditionally the soup is made with beef stock)
  • 1/2 cup of dry vermouth or dry white wine
  • 1 bay leaf
  • 1/4 teaspoon of dry thyme
  • Salt and pepper
  • 8 slices of toasted French bread
  • 1 1/2 cups of grated Swiss Gruyere with a little grated Parmesan cheese

Method

1 In a large saucepan, sauté the onions in the olive oil on medium high heat until well browned, but not burned, about 30-40 minutes (or longer). Add the sugar about 10 minutes into the process to help with the carmelization.

2 Add garlic and sauté for 1 minute. Add the stock, vermouth or wine, bay leaf, and thyme. Cover partially and simmer until the flavors are well blended, about 30 minutes. Season to taste with salt and pepper. Discard the bay leaf.

3 To serve you can either use individual oven-proof soup bowls or one large casserole dish. Ladle the soup into the bowls or casserole dish. Cover with the toast and sprinkle with cheese. Put into the broiler for 10 minutes at 350 degrees F, or until the cheese bubbles and is slightly browned. Serve immediately.

Serves 4-6.

I made this last night and was very happy with the results! This soup is sweet and rich. By the end of the bowl I was ready for bed (of course, a glass of novello helped).

I'd always thought French Onion Soup was fancy because of the presentation, but it was surprisingly easy. I'll be making this again! Although, I'll probably make less, and serve it as a starter so as not to put my guests into a food coma.

If you've got the time, I'd recommend starting at 10 AM and making a beef broth from scratch. The house will smell wonderful all day!

Very good!! Carmelizing the onions is key with any onion soup recipe, I will make this for years to come. Thanks Steve

Very cold day in Northern Wisconsin today. My friends and I did things outside. Came in and wife had made this soup. It was great, everyone loved it.

French onion soups has long been my 86 year old mother's favorite lunch...needless to say, she 's eaten a LOT of different soups all over the world and her comment was this, "What did you do differently? This is far and above the best I've ever had...I believe it was carmelizing the onions and the garlic...and the thyme and bay leaf not found in other recipes. Bon Apetit!

Made this last night, halving the recipe for two, and using sweet onions instead of red onions. Finished off the leftovers for lunch today. mmm. It was wonderful, as are all the recipes I've tried on this blog. Thanks, Elise!

This is the best french onion soup I have ever tasted, It is outstanding! I've made it on several occasions for a number of people and everyone loves it. Great recipe, thanks.

This recipe is fantastic! I used chicken stock instead of beef as that's all I had; I also put the entire finished mixture into my blender for a smooth and creamy soup. Dee-lish!

I made this soup for Christmas dinner, 12 people, it was a huge hit and equally scrummy the next day when we were sober!

I used smoked gruyere cheese, it gives the soup a strong flavor, it's very tasty!

Word of caution: I bought cheap "extra-dry" vermouth for this recipe, and I wish I had tasted it before I used it. It was very very sweet, almost like white grape juice. It threw off the balance of the soup, which was disappointing since I went through the trouble of making beef stock from scratch. If you don't normally cook with vermouth, or don't want to buy a more expensive bottle, it's probably smarter to stick with a regular dry white wine.

This was so good and really easy. I have made other recipes for onion soup but this beats them all. I always read comments to see if anyone has added or omitted anything, but it's perfect the way it is. Not much of a bay leaf fan, but I put a little dried in it and it was fantastic.
The last recipe I used took 2 days. This reduced down in a couple of hours. Note:
If you want to serve this to more than 2 people, double or triple the recipe, you will not be sorry!
Toast the bread to make it like croutons, that's the only thing I'd do differently

Made this today for the first time. It was amazing! I will be making this for years to come. What I like the best, is that it doesn't have the salt content that you normally get in restaurants.

Tried this recipe last night--it was AWESOME! Everybody RAVED!

Thanks!

Can any other type of cheese be used for this recipe?

Great question, I don't know! I've always made French onion soup with Swiss cheese, usually Gruyere. ~Elise

Just made this morning, have a little bit of the flu and once I had this French onion soup I felt a lot better. Although I substituted the toast with garlic parmesan croutons from costco and used gouda cheese instead of gruyere, it was fabulous. Thanks for the recipe.

Posted by: Peter on December 27, 2009 9:29 AM

Can dry sherry be substituted for the vermouth or dry white wine? Or would the results be too sweet?

I think it's really up to your taste. Try a little with it and see if you like it. ~Elise

Posted by: Catherine on December 28, 2009 1:56 PM

Umm I was wondering if you can use fish stock instead of beef or chicken? :D

Something tells me that wouldn't be particularly appetizing with this soup. But if you try it, please let us know how it turns out for you. ~Elise

I too made this soup and this recipe is terrific. The dry, white wine really gives it a nice flavor.

Hi Elise,

My kids and my husband loved your recipe. We all enjoyed the soup, especially when I could control the salt input! Thanks so much for sharing this wonderful recipe to everyone!

I wish you and your family a very happy and healthy New Year!

Thank you Diep, I'm so glad you liked it. A happy New Year to you too! ~Elise

Just used this recipe as a starting point for dinner. I only used beef stock, and used cabernet sauvignon rather than vermouth (personal preference). I'd never made French onion soup, so am pleased to report excellent results! Yes, caramelizing the onions is time intensive, but you will be repaid for your patience.

Posted by: Steve P. on January 22, 2010 2:21 PM

I made this soup over the weekend using 4 cups chicken broth and 4 cups beef. (It's all I had in the pantry). Elise, For the cheese I used grated swiss and then sliced havarti over that. It was fantastic! I will definitely make this again.

Posted by: Andie on February 1, 2010 7:35 AM

I just finished making this and I have to say it is absolutely delicious!!!! I had to use both chix and beef broth because I didn't have enough beef broth but I can't imagine it being any better!

Posted by: Janiva on February 6, 2010 11:20 PM

Is there a way to make this vegetarian?

You can use vegetable stock, but truly it will not taste the same. If you do so I would double up on the caramelized onions, you'll need it for the flavor. ~Elise

This soup was amazingly easy to make and so delicious. My entire family loved it!

Posted by: nikki on February 19, 2010 9:30 AM

Great recipe, only change was I added a little olive oil to the bread and toasted it. It was wonderful.

Posted by: Aaron on February 26, 2010 12:47 PM

Elise, this looks like a perfect onion soup! If I had some good homemade beef stock on hand, I would be in the kitchen right now making it. I like to use the individual bowls. Serving it from the large casserole can get a little messy with all that melted Gruyere (but that can be kind of fun).
