Cook’s notes
Called vichyssoise in France, story has it that it was Julia Child who brought leek and potato soup to the attention of the United States when she published a recipe in her book Mastering the Art of French Cooking. She called it an American invention but that’s really debatable.
Pureed leek and potato soup had been popular in France since the 19th century. It is often called “Potage à la Parmentier” after the man who popularized potatoes in French cooking. The traditional ingredients for vichyssoise are leeks, potatoes, chicken stock and cream. The difference between French vichyssoise and Julia Child’s vichyssoiseis the absence of cream in the latter.
With all due respect to the French, I have to side with Julia Child with regard to the omission of cream in making leek and potato soup. I feel that cream, especially when used in copiuos amounts, drowns out the natural flavors of the leeks and potatoes.
An immersion blender was used to puree the leeks and potatoes in this recipe. It is not a must. You may use a potato masher to break up the potatoes right in the pot once they are mushy. The soup will not be totally smooth but it will still be delicious.
Leek and potato soup
Ingredients
- ¼ cup butter
- 2 cups thinly sliced leeks
- 1 kilogram waxy potatoes cut into half-inch cubes
- salt
- pepper
- 6 cups chicken bone broth (you may need more)
- fried shallots (available in Asian groceries)
- finely chopped parsley
Instructions
- In a thick-bottomed pan, melt the butter and add the sliced leeks.
- Cook the leeks, stirring occasionally, until very soft.
- Add the potato cubes to the leeks, sprinkle in salt and pepper, and stir to coat the potato cubes with butter.
- Pour in the chicken bone broth, bring to the boil, lower the heat and cook until the potato cubes break apart when pierced with a fork.
- Off the heat, plunge an immersion blender into the pot and process until all solids are pureed.
- If the soup is too thick at this point, put back on the stove and pour in more broth. Bring to a simmer then add more salt and pepper, as needed.
- Ladle the leek and potato soup into bowls and garnish with fried shallots and chopped parsley.
