3/4 cup chopped leek (white and pale green parts only)
2 garlic cloves, chopped
1 teaspoon chopped fresh thyme
1/4 teaspoon fennel seeds
4 cups (or more) canned low-salt chicken broth
Additional chopped fresh thyme
Melt butter in large saucepan over medium-low heat.
Add carrots, onion, leek, garlic, thyme and fennel seeds; stir to coat.
Cover; cook until onion is translucent, stirring occasionally, about 15 minutes.
