I love how rich the green of this soup is. If your guest is adamant about eating soup with meat, brown some bacon and chop to smaller pieces. Add the bacon at the same time you garnish the soup with the asparagus tips.
1 bunch of asparagus, chopped, reserving the tips
1 leek, white parts only, chopped
1 medium red onion, roughly chopped
half a bunch of flat-leaf parsley, roughly chopped
half a stick of butter
grated lemon peel
1. Melt butter in a large soup pot. SautÃ© garlic and onions. Add leeks and cook until soft, about 3 minutes. Add the asparagus stems, onion and parsley with salt and pepper. Add vegetable stock and bring to a boil. Then simmer until asparagus is tender, about 5 minutes.
2. PurÃ©e mixture using a blender, in batches if necessary. Return soup to pot and thin with more stock if desired.
3. In a separate pot, boil some water and cook asparagus tips for about 2 minutes with some salt. Use as garnish for soup.
