More about the ingredients
You can use either Russet potatoes or Yukon gold potatoes. A russet potato is large. Its skill is brown with few eyes on it. The white and soft flesh is ideal for cooking this soup. This potato is used to make mashed potatoes or French fries. The Yukon gold potatoes have a nutty flavor and buttery texture. These are great for frying, boiling, or roasting.
Cooking method
First, melt the butter in a soup pot or add olive oil. Put garlic and leeks, stirring them continuously for about 10 minutes. Wait till they become soft making sure they don't turn out brown. Leeks have an onion-like flavor, so it tastes sweet. This soup is also called onion soup by many. Then add the vegetable broth, cut potatoes, bay leaves and thyme. Sprinkle salt, pepper, and paprika.
After bringing the contents to a boil, cover the pot and cook on low heat. After the potatoes become soft (might take about 15 minutes). Stop the flame and take out the bay leaves and thyme sprig (if you have used fresh thyme instead of the dried ones). Then blend the soup using a blender till you reach a smooth consistency.
Put the soup back in the soup pot. Add cream and cook for a few minutes on low flame. The soup will be a bit thick. Add extra seasoning if necessary and chopped chives before serving. You can also add herbs on top for an extra flavor. You can serve the soup with grilled or fried baguette slices. You can refrigerate the soup for 3 to 4 days in an airtight container. When reheating add some vegetable broth to make the soup lighter.
Tips
You must buy leeks that have green leaves and white bulbs. You may find it difficult to clean the leeks. You need to cut off the root end first and then cut the green tops. Separate the leaves and wash everything thoroughly. You should cook the leek slowly to prevent it from changing color.
You must ensure that the potatoes are tender to get the best texture. You will also find it easy to blend with your handheld blender. If you don't like your soup to be too creamy, you can avoid using fresh cream. An alternative approach is to press potatoes through a ricer to give them a clean and light texture. You won't have the glueyness anymore.
You can experiment with parmesan cheese and chili flakes to make the soup cheesy and hot. If you are not a vegan then you can add a few fried bacon in the soup too. As the soup is heavy due to the mashed potatoes and bacon, you won't need to have any other dish to accompany the soup.
