2 lbs. asparagus, from 2 bunches, tough ends snapped off
1 tbsp unsalted butter
1 medium onion, chopped
6 cups reduced sodium chicken broth
2 tbsp low fat sour cream
kosher salt and fresh pepper, to taste
Directions:
Melt butter over low heat in a large pot. Add the onion and sauté until soft, about 2 minutes.
Cut the asparagus in half and add to the pot along with chicken broth and black pepper, to taste. Bring to a boil, cover and cook low about 20 minutes or until asparagus is very tender.
Remove from heat, add sour cream and using your hand held blender, puree until smooth.
