How to Make Our Favorite French Onion Soup
Caramelize Onions: Melt butter in a large pot over low heat and add the sliced sweet onions. Cook slowly for about 30-40 minutes, stirring occasionally, until they turn a rich golden brown.
Deglaze Pot: Pour in the dry white wine, stirring gently to lift any browned bits from the bottom of the pot. This enhances the flavor of the soup beautifully.
Add Broth and Herbs: Add the thyme sprigs and broth to the pot. Bring it to a simmer, cooking for an additional 30 minutes to meld those delicious flavors together.
Prepare Toppings: While the soup simmers, preheat your oven. Slice the French bread or ciabatta and top each piece generously with Gruyère cheese.
Broil Soup: Carefully transfer the soup into oven-safe bowls, place the bread on top, then broil until the cheese is bubbling and golden brown—about 3-5 minutes.
Optional: Garnish with fresh thyme leaves for an extra pop of flavor.

Our Favorite French Onion Soup Recipe FAQs
What kind of onions should I use for the best flavor?
Absolutely! For the best results, always use sweet onions like Vidalia or Walla Walla. They provide the rich, sweet flavor essential to French onion soup. Avoid yellow onions, as they can alter the taste and don’t offer the same level of sweetness when caramelized.

Can I freeze French onion soup? How do I do it?
Yes, you can freeze French onion soup for up to 2 months. To freeze, let the soup cool completely, then pour it into freezer-safe containers, leaving some space for expansion. If you prefer, you can freeze the caramelized onions separately to make preparation quicker next time. When ready to enjoy, thaw overnight in the fridge and reheat gently on the stove, adding a splash of broth if needed to regain your desired consistency.
What should I do if my soup is too salty?
If you find your soup a bit too salty, don’t worry! A great fix is to add additional unsalted broth or water to dilute the saltiness. Start with small amounts to avoid losing the soup’s flavor. You could also add a raw potato to soak up some of the excess salt—just remember to remove it before serving!
