French Onion Soup With Gruyère

Pair this delicious soup with a crusty baguette. This delicious French soup is easy to make and sure to impress your guests. It’s one of our favourite for sure!

With this recipe it’s very important that you caramelise the onions very well, they need to be a very nice dark colour. Don’t rush this process, it’s very important for the taste of the soup. Never just throw the onions in the whine wine and the stock, you’ll miss a lot of the taste of the onions.

You can have this soup as a starter but also easily as a meal for dinner of lunch. As as starter reduce the size of the portions, otherwise you won’t be able to get on to the next course.

What is caramelising onions?

Caramelized onions are simply onions that are cooked for an extended period of time with a bit of fat (either oil or butter). This extended cook time allows the natural sugar in the onions to brown and caramelize
