This classic French asparagus soup is simple and make-ahead friendly, and a perfect choice for entertaining when asparagus is in season. Before you start, considering cutting the tips off some of your asparagus stalks and blanching them separately—it'll make a brilliant garnish for each serving. To make the soup, simply sauté onions and asparagus in butter, add chicken stock, simmer until tender, and puree into a smooth, silky soup with crème fraîche or heavy cream. Just before serving, rewarm the soup and monter au beurre—that is, stir in a bit of cold butter to make the soup extra silky and rich. Because yes, it's true: everything is better with butter.
Soup keeps, covered and chilled, 2 days. If making ahead, add last tablespoon butter and lemon juice after reheating.
