After bringing the mixture to a boil, reduce the heat and simmer for 20-25 minutes, or until the potatoes are tender.

How should I store leftover Spicy Potato Tarragon Soup?

Let the soup cool to room temperature, then transfer it to an airtight container. It can be stored in the refrigerator for up to 3-4 days or frozen for up to 3 months.

Cooking Tips:

- Taste the soup before adding the lemon juice and adjust the seasoning as needed.

- For an added depth of flavor, consider roasting the fennel and garlic before adding them to the soup.
