Cream of Zucchini Soup

Preheat oven to 350°F. Combine bread cubes and 1 tablespoon oil in a bowl; toss well. Spread in an even layer on a large baking sheet. Bake until golden and crisp, 12 to 15 minutes.

Meanwhile, heat the remaining 1 tablespoon oil in a large pot over medium heat. Add shallots; cook, stirring occasionally, until softened, about 3 minutes. Add broth, zucchini, potato and salt; bring to a boil over high heat. Reduce heat to medium-low; simmer, undisturbed, until the vegetables are tender, about 15 minutes.

Pour the zucchini mixture into a blender. Secure the lid on the blender and remove the center piece to allow steam to escape. Place a clean towel over the opening. Process until smooth and silky, about 1 minute. (Use caution when pureeing hot liquids.) Return the mixture to the pot; stir in cream. Ladle the soup into 6 bowls; sprinkle with the croutons and chives.
