Cream of Leek Soup
This soup is super creamy in texture, but it contains no actual cream. The butter and flour mixture -- what's called a roux -- gives it body and silkiness.
- 1/4 cup (1/2 stick) unsalted butter
- 10 sliced medium leeks (white and light-green parts only), rinsed thoroughly after slicing (about 8 cups)
- 1/4 cup all-purpose flour (spooned and leveled)
- 4 cups low-sodium chicken broth
- 1 tablespoon chopped fresh tarragon
- Coarse salt and ground pepper
In a medium pot, melt butter over medium. Add leeks and cook, stirring occasionally, until softened, 8 minutes.
Add flour and cook, stirring, until combined, 1 minute.
Whisking constantly, add broth and 1 cup water and bring to a boil over high. Reduce heat and simmer, whisking occasionally, 10 minutes. Add tarragon.
Transfer mixture to a large bowl. In batches, fill a blender halfway with mixture and puree until smooth; to allow heat to escape, remove cap from hole in lid, cover lid with a dish towel, and hold down firmly while blending. Return soup to pot as pureed.
Heat over medium until warmed through. Season with salt and pepper. Thin with broth or water, if desired.
