The best French Onion Soup with slow cooked caramelized sweet onions, crisp baked crostini and plenty of smooth melting Gruyere Cheese. This is the ultimate comfort soup and is so quick and easy to make.
This is one of my husband’s favorite recipes. If you love onions than this delectable mouthwatering soup is a must make recipe. We make this tasty treat at least once a month and we love every spoonful. It is such an easy recipe that even the novice chef can handle this.
How to make French Onion Soup
Start by heating a little butter and olive oil in a Dutch Oven or stock pot over medium heat. Add the onions and cook for about 45 minutes stirring every few minutes until a rich golden brown. You may need to reduce the heat if they are browning too fast. There is a fine line between stirring too much and not stirring enough. The key is to stir them enough to keep them from burning but not so much that they are not browning.
Once browned stir in the garlic and dried thyme. Add the wine and scrape the bottom of the pan to remove the browned bits. This technique is known as deglazing. Now let the wine and onions simmer for a few minutes. Next add the beef broth, chicken broth and bay leaf and simmer for about 20-30 minutes. Discard the bay leaf and season with salt and pepper to taste.
Spoon into oven proof soup bowls, add several crostini to the top and sprinkle with shredded cheese. Set them on a baking sheet and place under the broiler for a few minutes to melt the cheese. Plan to serve promptly.
Helpful tips for making French Onion Soup
- Caramelized onions are the star of this show so don’t cut the process short.
- Either dry red wine or dry white wine can be used. Red adds a more robust flavor and white more subtle. If you have a personal preference on which one you prefer to drink go with that.
- You can use all beef broth for a richer fuller flavor or if it is just more convenient. I always have beef and chicken broth in the house so a combination is usually the way I go on this recipe.
- I find Crostini works best for this recipe. They hold up long enough to provide structure and texture without coming off as a soggy piece of bread.
- Gruyere is a smooth melting type of Swiss Cheese with fewer and smaller eyes. If it is not available you can substitute Swiss or Jarlsberg.
- Broilers are very unpredictable. Stay close by and monitor well.
I love french onion soup. There is just something dreamy about all those onions slow cooked to complete perfection, then simmered in broth and spice, and topped with crostini and rich cheese! My friends life just does not get much better than this.

Hi why must use two type of broth. I do not take beef so can i use any other broth beside chicken broth
Just use all chicken broth. It will still be delicious!
Why does the picture of the food never ever print out on the print sheet when one has it set to print it…That should be corrected….
I will see what I can do. Thanks!
Save in your computer-When you want to make then pull up on your phone-tablet or laptop from a 68 year old man that loves food and have every recipe at my fingertips

This is just like mine, only difference is I use fresh parsley and thyme …. sooooo good ? One time I even used leftover Champagne!
I am making this tonight! I am so glad I found your page. I love your recipes and already have several of them saved to make in the future. They are homey and remind me of my mother’s cooking. I love that they are not pretentious, in the writing or the execution, and that you are flexible with people making suggestions or variations. My variation on the Onion Soup is that I only have cooking sherry on hand for the white wine, and that the chicken broth part will be bouillon. I think it will be fine though, and have a feeling you will say it should be fine, too! Thanks for your great contribution of helping every day cooks create great meals. Subscribed!

Thanks so much Joanna! I really appreciate your kind words. They mean a lot to me. I would have responded earlier but we went out to dinner. You are correct those substitutions will be just fine…those are substitutions I would make myself. I mean honestly who wants to run to the grocery store yet again. I love a cook that can improvise since there are a dozen ways to make every single recipe taste good. Have a fabulous evening.

I love french onion soup but never felt confident enough to make it from scratch at home! Your recipe has inspired me to give it a try!
★★★★★
I didn’t make this yet. But instead of beef broth, I use beef consume, I find even better taste.
What do you suggest serving along with the soup? I want to make this for a small luncheon I am planning.
★★★★★
How about baked salmon with garlic butter or Smoked Salmon Patties, roasted or marinated veggies, a light salad like an arugula salad with parmesan and a light vinaigrette, steamed shrimp or Seared Scallops. Any of these would be delicious with the soup.
Yum! Such a wonderfully savory soup! I love the mix of beef and chicken broth! Using both broths gives such a wonderfully deeper flavor! The Gruyere cheese is great on here. I hadn’t thought of using that one. Usually I use provolone with a touch of parmesan.
This is one soup I never ever get tired of, SO delicious!

OMG, yes! This looks amazing. I love French onion soup. Will have to try this recipe soon!
Miss Beth, what can I use in place of garlic? I am allergic. Most recipes call for it and I never know how to replace it. Afraid they will taste to bland. Thank you!
Some people say you can caramelize celery and it gets close to the flavor and smell although I have never tried it. Please Let me know if you do and how it turns out.
