Classic French Onion Soup

This One Pot Classic French Onion Soup is the ultimate cold weather comfort food! Think the soup you know and love, just made better and easier! The real secret to this one-pot soup is the little bit of white wine, to round out the flavors and to give it some nice acidity. It’s definitely those classic French onion soup flavors we all love so much. Made with two types of broth, freshly sliced yellow onions that have been cooked to perfection, finished with a few slices of Sourdough Bread and fontina cheese, run under the broiler for a minute to get the bread perfectly toasted and that cheese deliciously melty. This soup is great any night of the week but is definitely perfect for your next get-together during the colder months. Every last bite is SO good and everyone loves a true, classic French onion soup…especially when it’s homemade and caramelized onions are involved! This dish will be your new go-to when serving family and friends over the holidays…and pretty much any other time throughout the year!

About The Recipe

One of my very first memories of trying French Onion Soup was on a cold day at Be Our Guest in Walt Disney World. I wasn’t sure if I was going to like it, but I honestly fell in love and the soup warmed me from the inside out! It was a comfort food that actually felt truly comforting and warming.

I asked my mom about it on that trip and, turns out, she had been making French onion soup for years! From that moment on, this soup has been a staple dinner for us during the Fall and Winter months.

And, even though the rest of the country is still probably warm during these last few days of August, it’s getting cold here! Fall is definitely on its way and not holding back

There are actual leaves beginning to turn in our backyard!

So, we couldn’t think of a better way to end the summer and kick off the start to Fall than with this classic French onion soup! I mean, can it get better than a simple dinner that can be made year-round and always be delicious?

I think this soup is definitely one of my favorite things we make. Sometimes, I wish it was cool enough in the summer just so I can enjoy a big bowl (or cute copper pot!) of this.

How To Store

Once the soup has cooled, you can ladle the soup into an airtight container and keep in the fridge for 3-5 days. You can also ladle 1 cup servings into a freezer safe bag and keep in the freezer for months!

Substitutions

  • If you don’t have homemade chicken stock or beef stock, you can use bullion cubes or your favorite store-bough brand.
  • Dried thyme can be used in place of fresh, but you will need to decrease the amount to about 1/8 teaspoon.
  • Fontina is our favorite with this soup, but you can use any kind of white cheese like it! From gruyère to a white cheddar.

Expert Tips

  • Make sure the onions are thinly sliced! I highly recommend using a mandoline to make the slicing easier!
  • Use a white wine with a lot of citrus!
  • This soups keeps and reheats really well.

  1. This recipe is amazing! I have made it a few days ago and my whole family enjoyed. Especially my 7 year old son. He said “this is the most delicious food I’ve ever eaten in my life” I even tapped a video on this and and share on my IG stories @diligent_desserts. It was super cute to know my little one liked this soup!
