Spring onion soup or Scallion soup recipe – creamy, thick, smooth and flavorful soup recipe made from spring onions (aka scallions, green onions) and potato.

Spring onion has other names like green onion or scallion. Some has bigger bulb at the bottom while some are thin like I am using here. It depends on where you live. But all are same just the different size.

Addition of potato makes the soup thick and creamy.

I have used homemade vegetable stock here. This vegetable stock adds extra flavors to the soup. But of course you can use water instead. It will still taste good. But the stock is better.

I have been making this soup since past 7-8 months. Earlier I was using canola oil and the taste was good. But after some time I saw spring onion soup recipe in a ‘Vegetarian soup cookbook’ which was made using Olive oil and garlic is sauted in till light brown. I tried this way and it was much much better than earlier version. Since then I am making with olive oil only.

This soup recipe requires very few ingredients. It is delicious and has subtle flavor of spring onions.

Addition of lemon juice perks up the flavors and taste. So please don’t skip.

7) Simmer it till potatoes are cooked and soft.

8) Let it cool down a little bit and make smooth puree in grinder or blender. Or use immersion hand blender. The soup is thick yet right consistency. If yours is too thick then you can thin it out as per your liking by adding more stock or water.
