What Texture Should French Onion Soup Have?

- Take a clean tablespoon and scoop broth from the pot into the flour.

- Stir gently and continue to add a tablespoon at a time until the onions are evenly coated.

To avoid an overly sweet soup on your next attempt, try using a less sugary wine or stock option.
How Do You Fix French Onion Soup That Is Too Salty?

How Do You Fix French Onion Soup That Is Too Bland?

In future attempts consider caramelizing the onion a bit longer to bring out the full flavor in the soup.

- Ladle the soup into the individual crocks.
- Place your cheese on top.
- Put the crocks on a baking sheet and insert them into your oven.
