How do you fix soup with too much onion?

- Add more liquid: Adding more liquid, such as water or broth, can help to dilute the onion flavor.

- Add a contrasting flavor: Adding a contrasting flavor, such as sweetness (honey, sugar) or acidity (lemon juice, vinegar) can help to balance the onion flavor.

- Add dairy: Dairy products, such as milk, cream, or cheese, can help to mellow out the onion flavor.

- Add a starch: Adding starch, such as flour, cornstarch, or rice, can help to thicken the soup and reduce the onion flavor.

- Blend the soup: Use an immersion blender to blend and puree the soup until smooth, this will help to incorporate all of the ingredients and reduce the onion flavor.

- Serve with toppings: Serve the soup with toppings that can help to mask the onion flavor, such as croutons, cheese, sour cream, or chopped herbs.
