For the love of zucchini, here comes another recipe; as predictable as rain at this time of the year.
I appreciate the delicacy of flavor in this simple soup. You may substitute onions for leeks, or add richness by substituting butter for the olive oil and garnishing with creme fraiche. I added spinach primarily for color so fresh parsley may be substituted for that. I enjoy buttermilk in cold summer soups but plain yogurt is always an excellent substitute.

Chill Time: 2-24 hours
Yield: 6-7 cups
2 tablespoons extra-virgin olive oil
2 leeks, white and light green parts only, washed thoroughly, then thinly sliced
5 medium-sized zucchini, washed, halved lengthwise, then cut crosswise into 1/8-inch-thick slices( 5 cups)
Zest and juice from 1/2 lemon
3 1/2 cups chicken or vegetable stock
1 cup loosely packed fresh-spinach
1 tablespoon finely chopped fresh tarragon

2. Add zucchini, lemon zest and juice, and simmer, stirring occasionally, about 5 minutes or until zucchini is softened. Add stock and simmer an additional 6-8 minutes, stirring in spinach the last couple of minutes.
3. Purée zucchini mixture and tarragon in a food processor or with an immersion blender until smooth (use caution when blending hot liquids).
4.Stir in buttermilk and season to taste with kosher salt and freshly ground pepper.
