Meanwhile, preheat the oven to 375°. Spread the walnuts in a pie plate and toast for 5 to 7 minutes, until golden. Let cool, then finely chop and transfer to a bowl. Add the oil, parsley and grated cheese and mix well.

In a blender, puree the soup in 2 batches until very smooth. Pour into a clean saucepan and stir in the heavy cream; season with salt and pepper and reheat if necessary. Serve topped with the walnut gremolata.

Make Ahead:

The soup can be refrigerated for 2 days.
