What Are Leeks?
Leeks are a mild, slightly sweet vegetable that belongs to the onion family. They add a delicate flavor to soups and stews without being overpowering.
Because they grow in sandy soil, it’s important to clean them well. Slice them first, then rinse thoroughly to remove any dirt trapped between the layers.

How To Make Slow Cooker Chicken Leek Soup
This recipe is as simple as it gets. Add your ingredients to the slow cooker and let everything cook low and slow until tender and flavorful.
Once the chicken is cooked through, shred it into bite-sized pieces and return it to the soup. This helps distribute the flavor evenly throughout the dish.
You can adjust the seasoning to your taste before serving.

Tips For The Best Chicken Leek Soup

- Shred the chicken while warm for easier handling
- Adjust seasoning at the end for the best flavor
