Notes

Substitutions:

If you don't have homemade chicken stock or beef stock, you can use bullion cubes or your favorite store-bought 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 you prefer. A couple of good suggestions are Gruyère and white cheddar.

Tips For The Best French Onion Soup:

Make sure the onions are thinly sliced! I highly recommend using a mandoline to make the slicing easier!
Use a white wine with citrus notes!

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 (or your preferred amount) into a freezer safe bag and keep in the freezer for months!
