This refreshing asparagus and leek soup recipe is pureed in a blender or vitamix for an uber creamy texture without cream. Make vegan asparagus soup by using a butter alternative.
Trim the delicate tips and rough stem ends off the asparagus and cut the remaining tender asparagus into 1" pieces. Set tips aside in a small bowl.
Add toughends and thyme to a medium pot, add broth, and bring to a boil. Reduce heat to a simmer, cover, cook ~ 20 minutes. Remove stem ends and thyme with slotted spoon and discard.
Optional For Garnish: Add ¼ of asparagus tips to broth and blanch (cook) ~ 1 minute or until tender. Remove tips with slotted spoon and place in an ice bath. Drain water once cooled and set tips aside on a paper towel for garnish.
Bring a medium sized pan to medium high heat and melt butter.
Add leeks and shallots and cook ~ 4-5 minutes or until tender. Add this mixture to the pot of broth and also add remaining uncooked asparagus pieces.
Bring to a boil, reduce heat, and simmer covered (stirring occasionally) an additional 25 minutes or until asparagus is very tender.
Immersion blend or add to a blender (you may need to do this in batches) and puree soup until smooth.
Add salt to taste and garnish with asparagus tips. Happy soup eatin'! Beckie
