Creamy caramelized onion soup with garlic croutons

When I have to decide what kind of soup I want, I always go for the smoothest or creamiest.

I saw a picture of onion soup and thought I needed to try to turn this classic into a creamy soup.

The combination of the sweetness of the onion with the saltiness of the bouillon, and the smoothness of the overall dish with the crispiness of the croutons drives me crazy (in a good way). I hope you’ll like it as much as I do.
