This Caramelized Onion Soup is simple and delicious and loaded with sweet onions. It’s an all year round favorite!
Soup’s on friends! Come and get it!
Soups are huge on the menu at our house during the fall and winter. Today, I’m sharing one of my favorite soups, Caramelized Onion Soup. I LOVE the taste of caramelized onions in just about anything. They are sweet and savory, and help boost the flavor of any dish. I love to add them to omelettes, soups, burgers and salads. They turn the ordinary into extraordinary!
The reason why I love this soup is because it’s lighter than another popular favorite, French Onion Soup Gratinee. Now, don’t get me wrong, I love soup loaded with cheese as much as the next guy, but this Caramelized Onion Soup won’t leave you feeling guilty. I did add two small baguette slices per bowl and just a small sprinkle of some gruyere cheese, and it was just as good as the cheese loaded version.
The secret to making delicious caramelized onions is to cook them nice and slow. You don’t want to rush the process or they will burn. You want to set the heat to medium, and slowly the sugars inside the onion will caramelize, and the onions will turn a rich brown and become intensely flavorful.
So grab a spoon friends, and cozy up to this sweet and savory soup this fall. You can enjoy it on its own or have it alongside a salad or even a nice, juicy burger. Either way, I guarantee it will become a favorite! Have a greet week friends!

I’m with ya, Mary Ann… caramelized onions on anything!! ANYTHING!! My hand is up high! One of my favorite things is French Onion Soup and I make it often in the coldest part of the year. Such a classic recipe and oh so comforting. Thank you for this my dear! Have a beautiful week!
Absolutely Traci! They’re my favorite! As a kid, Saturday night was usually burger and soup night at our house in the fall/winter, and my Mom made the best French Onion Soup! Brings back great memories!
No lie, I CAN and HAVE eaten VATS of just caramelized onions. I am slightly obsessed… and not ashamed. :) So you can probably guess that Caramelized Onion Soup is one of my ALL TIME favorite soups, EVER! Yours looks simply divine! I must get my grubby, onion loving hands on a couple bowls of this,stat! Pinned! Cheers, my dear friend! xo
I’m not ashamed either Cheyanne! They really can make any dish so much better! I hope you have a wonderful week, and as usual, thanks for the sweet comment! :)
You’re not alone Cheyanne! ;)
I have never made onion soup before but have always wanted to. I’m a big onion fan and a big soup fan so this is perfect. Your house must have smelled great when you were making this. Do you think by switching out the beef broth with veggie broth it would still work? Love the simple baguette and parmesan toppers – sometime french onion soup goes overboard on the cheese (I can’t believe I’m saying that because I love cheese!).
You really should try this recipe Geraldine because it’s so easy and delicious! And yes, you can absolutely switch out the beef broth for vegetable broth. I LOVE the smell of onions cooking, and love my cheese too, but sometimes I like to change it up with a healthier version. Enjoy!
I do believe it is impossible to eat too much caramelized onion soup. And wow, Mary Ann! Yours looks amazing! I agree — sometimes simple is better in going easy with the cheese. :) Pinning!
Thanks so much Lauren! Thanks for the comment and for pinning too! Enjoy your week!
I could totally dive into a bowl of this! I just love me some slowly caramelized onions!

Thanks so much Jennifer! It’s on my fall soup list along with your chicken pot pie soup!! Enjoy your week!
Caramelized soup is my favorite! Especially when it has that melty cheesy toast soaking in all the delicious broth.
I can’t resist that melty cheesy toast either Nicole!
I’m a sucker for that melty cheese and those caramelize onions. Looks gorgeous and so comforting!!
Thanks so much Liz! It’s a family favorite here too! Perfect for those chilly fall nights in New England!
There’s nothing more comforting than a bowl of onion soup!
Absolutely Sue! Thanks so much for commenting.
Caramelized onions have always been a favorite of mine, so I am pretty much just swooning over this right now! I really agree with Sue^: there’s just so much comfort in a big bowl of warm onion soup. And I love how you kept things traditional with the gruyere and baguette! Nice job with this recipe! :D
Thanks so much Kennedy!
Soup is on the menu at my house as well at least once a week in the Fall and Winter. Onion soup is one of my favorite soups! Love that you went lighter on the cheese. Can’t wait to make this one!
