To make the asparagus velouté, begin by preparing the asparagus. Trim the ends and cut the spears into 1-inch pieces. In a large pot, sauté a chopped onion in butter until translucent. Then, add the asparagus pieces and sauté for another minute. Add enough water or chicken broth to cover the asparagus and simmer until tender, about 10-15 minutes.
Using an immersion blender or transferring to a blender or food processor, puree the asparagus mixture until smooth. Return the puree to the pot and add heavy cream, salt, pepper, and a pinch of nutmeg. Heat the soup gently until hot, but do not boil.
To make the potato dumplings, start by boiling peeled, diced potatoes in salted water until tender. Drain the potatoes and mash them with a fork or potato masher until they are smooth. Add an egg, some flour, salt, and pepper to the mashed potatoes and mix well until a sticky dough forms.
Using a spoon, scoop out small pieces of the dough and roll them into small balls. Drop the dumplings into boiling salted water and cook for 3-5 minutes, or until they rise to the surface. Remove the dumplings from the water with a slotted spoon and drain on a paper towel.
To serve, ladle the hot asparagus velouté into bowls and top with a few potato dumplings. Garnish with chopped fresh herbs or grated cheese, if desired. The creamy soup and tender dumplings make for a comforting and flavorful meal.
