Zucchini Soup with Basil

This is a classic summer soup. The recipe comes from my mom, and although she prefers to serve it warm, I really like it chilled. Following this is a recipe for croutons that taste great with the soup.

3 T. margarine (or unsalted butter for the purists)
3 T. extra virgin olive oil
3 celery ribs, diced
1 med. onion, minced
1 bay leaf
½ t. chopped thyme leaves
11/2 pounds small zucchini, cut into ½ inch pieces
3 c. chicken broth (vegetable broth will work too)
salt and pepper
8 small basil leaves


In a large heavy saucepan, melt the margarine in the olive oil. Add the celery, onion, bay leaf and thyme and cook over low heat, stirring occasionally, until the onion is soft (about 20 minutes). Increase the heat to moderate, stir in the zucchini and broth, season with salt and pepper and simmer the soup until the zucchini is soft (about 10 minutes). Don't forget to toss the bay leaf before blending!

Puree the soup in a blender (in small batches) until smooth. Return the soup to the saucepan and reheat gently, Season with salt and pepper. Ladle the soup into bowls, top with croutons, tomatoes, or basil leaves.
