Delicious French Onion Soup
When it’s this cold out, and I need comforting, I crave soup. You can’t go wrong French Onion Soup……a sweet oniony broth topped with crunchy croutons covered in melted cheesy goodness!
The key to a great French onion soup is caramelized onions. This step can be done in about a half-hour, but if you have the time, slowly caramelize them for a few hours on low heat, you won’t be sorry! It brings out so much more of the sweetness and flavor.
How To Make Easy French Onion Soup
After you have caramelized the onions, you make the broth, which is flavored with a little bit of dry wine, I like to use Chardonnay, Worcestershire sauce, garlic, and thyme. Let it all simmer about 40 minutes to let all of the flavors come together.
The final step is what makes French Onion Soup so hard to resist.

This is the best part! Just before serving, top each bowl with croutons and lay a few slices of gruyere cheese on top. Place your bowls on a baking sheet and pop them under the broiler for just a few minutes. Keep a close eye on it, and pull them out just as the cheese starts to melt, bubble, and turns a nice golden brown.

French Onion Soup
A decadent French Onion Soup full of flavor that is topped with croutons and melted gruyere cheese.
Ingredients
- 1/4 cup butter
- 2-3 large white or yellow onions (or 3-4 medium), sliced
- 1 teaspoon sugar
- 1/2 teaspoon salt
- 1 teaspoon minced garlic
- 1/2 tablespoon dried thyme
- 1½ tablespoon flour
- 1/2 cup dry white wine
- 2 cups beef broth
- 1½ cups chicken broth
- 1/2 tablespoon balsamic vinegar
- 1/2 tablespoon Worcestershire sauce
- Croutons (homemade or stor bought)
- 4 slices gruyere cheese (about 2 ounces)
Instructions
- Melt butter in a heavy soup pot or Dutch oven over medium heat, add the onions and stir until they are evenly coated with butter and sprinkle with salt and sugar.
- Turn the heat to medium-low, let onions cook, stirring occasionally,for at least 30-45 minutes. You can let them cook even longer over a low heat with the lid on until golden brown and caramelized, about 2-3 hours, stirring every 15 minutes. — just don't let them burn or get black. Adjust the heat as necessary.
- With medium-low heat, add the garlic and thyme and saute for about a minute.
- Mix in flour and brown for about another 2-3 minutes, forming a paste, but try not to scorch it.
- Add the wine and scrap the bottom of the pan to get up all of the cooked-on brown bits.
- Add broths, vinegar and worcestershire sauce, bring to a boil then reduce the heat and simmer for 30-40 minutes.
- Ladle the soup into oven-safe bowls on a baking sheet and top with croutons and a a thick layer of cheese, making sure to cover the edges of the croutons to prevent burning.
- Place under broiler, watching closely, until cheese melts, bubbles and turns a golden brown.
- Dunk the croutons and cheese into the soup as you eat. Enjoy!

French onion soup is a favorite in my household, and yours looks perfect! I love these pictures…I just want to dive right into the middle of that melty Gruyere and eat my way out!
thanks so much Taylor!
I absolutely love French onion soup – your recipe looks perfect!
Oh my gosh, this looks so warm and comforting! Perfect for a day like today!
Nothing warms the soul like soup-especially this delicious french onion one! I need some today-it’s another cold one! Stay warm!
Cheryl this is so inviting! I love the scene you’ve set with this delicious soup. I empathize on the chill of winter. We have snow right now. How about a Downton Abbey marathon? Great characters, beautiful scenes; no blood-splattered walls!
That’s on our list to watch after we finish a few others……we are watching too much right now! lol nothing else to do
Oh man its a cold day and Texas and I could totally warm up with this for lunch.
That soup looks so warm and tasty! Two of my sons are soup fanatics, so this will be a new one to try for them. Thanks!
This looks sooooo good. I love soup. Especially French Onion! I haven’t tried croutons in it like that before. I can’t wait to make it like this.
I totally just made french onion soup last week but this recipe has me itching to make it again. Delicious!
I can feel the warmth already. This looks scrumptious. Pinning.
French Onion is my favorite soup! Love the idea of using croutons on top. Yum!!!
This is my fav thing to have for dinner on a very cold night.
Too bad for us, we haven’t had much of a winter here at all.
Texas toast croutons are a great idea and I love that you add Worchestershire & balsamic for a richer flavour.
Gonna have to try this recipe of yours, Cheryl. Thanks!
Your photography is excellent and makes your mouth water!
Do you think using veggie broth would be an ok substitute? I don’t eat meat. Thanks
sure I don’t see why not!! enjoy!
I could cozy right up to a bowl of this Cheryl!
i need this! it’s so cold
Not much beats a good homemade french onion soup. This looks so cozy and delicious. Wishing I had a bowl now!
It’s perfect soup weather! The crunch bread and melted gruyere on top look so comforting and delicious!
I haven’t made French Onion Soup in ages. It’s my husband’s favorite. Great idea for Valentine’s Day!
My husband’s favorite soup…yours looks wonderful!!!
Now that is one beautiful bowl of soup Cheryl! It’s a family favorite so I’m definitely going to have to give this a try 🙂 Pinned!
Cheryl, this French Onion Soup looks amazing! I’m wishing I could just reach through the screen and have a big bowl of it for lunch today. I pinned it already and shared it on one of the popular group boards I’m a part of!
This made my mouth start watering immediately. I always used to get French Onion soup at Panera, but lately, it hasn’t been tasting as good to me. I think I need your homemade version! And, your pictures are beautiful, as always!
I am starving. This is not helping.
If looking to double would you double all ingredients? I know with some recipes that is not always the case. Have a family of 6 and 4 servings would not be quite enough:)
