Broccoli Soup with Curried Crème Fraîche

3 tbsp olive oil
2 cups chopped leeks (2 medium leeks, white and light green parts only)
1 russet potato (about 12 oz), peeled and cut into 1-in cubes
1 lb broccoli florets (see market note)
6 cups chicken broth
Kosher salt
1/8 tsp cayenne pepper plus more if needed
2/3 cup crème fraîche (see market note)
1 tsp curry powder
1 1/2 tbsp chopped flat leaf parsley or chives, for garnish

1.In a large heavy pot (with a lid), heat the oil over medium heat. Add the leeks and sauté until softened, about 4 minutes. Add the potato and broccoli florets and sauté, stirring, 1 minute more. Add the chicken broth, 1 teaspoon salt, and 1/8 teaspoon cayenne. Bring to a simmer, cover, and cook until the potatoes and broccoli are tender, 10 to 15 minutes. Purée the soup in a food processor, blender, or food mill, and return the soup to the pot. Or, use an immersion blender to purée the soup in the pot.

2.In a medium bowl, mix together crème fraîche and curry powder. Whisk half of the mixture into the soup until well blended. Taste the soup and season with more salt, and additional cayenne pepper (for a spicier taste) if needed. (Soup can be prepared 1 day ahead; cool, cover and refrigerate. Reheat over medium heat, stirring occasionally.)

3.Ladle soup into bowls and garnish with a dollop of the remaining crème fraîche and some chopped parsley or chives.
Serves 6

Market notes:
Using broccoli florets is a big time saver; they are available packaged in most supermarkets in the produce section.

Crème fraîche, a thick cream used in French cooking, is available in the dairy section of many supermarkets. If you can’t find it, the following recipe works well.

1 cup heavy cream
1/3 cup sour cream

Whisk cream and sour cream together in a medium non-reactive bowl. Let stand at room temperature until thickened, 6 hours or longer. Cover and refrigerate. (Crème fraîche can be stored up to 1 week, covered, in the refrigerator.) Makes about 1 1/3 cups.
