• 1 large bunch broccoli (about 1 1/2 pounds)
• 1 tablespoon olive oil
• 1 tablespoon unsalted butter
• 2 medium leeks , white and light green parts only, thinly sliced
• 1 medium baking potato , peeled and cut into 1-inch pieces
• 1 clove garlic , thinly sliced
• 3 cups low-sodium chicken or vegetable broth
• 3/4 teaspoon salt
• Pinch freshly ground pepper
• 1/4 cup half-and-half (optional)
• 1/4 cup snipped chives

Separate broccoli stems from florets. Using a vegetable peeler, peel stems to remove tough outer layer, then slice into 1/4-inch-thick "coins." Break or cut the florets into small pieces. Reserve stems and florets separately.

In a medium saucepan, heat oil and butter over medium heat. Add leeks and cook, stirring often, until softened and fragrant, about 3 minutes. Add broccoli stems, potato, and garlic, and cook 2 to 3 minutes. Add 3 cups water, broth, salt, and pepper; bring to a boil. Reduce heat; cover partially and simmer until broccoli and potato are tender, about 12 minutes.

Add florets; bring to a boil and then simmer 5 minutes. Transfer soup in batches to a blender or food processor, and puree until smooth. Return soup to saucepan; add half-and-half (if using) and chives, and reheat briefly.
