Step‑by‑Step Instructions for Hearty White Bean Fennel Soup
Step 1: Sauté the Aromatics
In a large saucepan, heat 2 tablespoons of olive oil over medium heat. Add 1 chopped onion and 1 thinly sliced fennel bulb, stirring frequently. Sauté for about 5-7 minutes, or until the onion is translucent and the fennel is softened. This will create a fragrant base for your Hearty White Bean Fennel Soup.
Step 2: Combine the Base Ingredients
Pour in 4 cups of reduced-sodium chicken or vegetable broth, followed by 2 cans of rinsed and drained cannellini beans, and 1 can of diced tomatoes. Sprinkle in 1 teaspoon of dried thyme and freshly ground black pepper to taste. Add 1 bay leaf for enhanced flavor. Stir everything well so all the ingredients mingle nicely.
Step 3: Bring to a Boil
Increase the heat to high and bring the soup mixture to a rolling boil, which should take about 5 minutes. Keep an eye on it to prevent overflow. Once boiling, you’ll notice the vibrant colors of the soup intensifying. This step ensures the flavors meld beautifully in your Hearty White Bean Fennel Soup.
Step 4: Simmer to Perfection
Reduce the heat to low, cover the saucepan, and let the soup simmer for 30 minutes. During this time, the fennel will become tender, and your kitchen will fill with delightful aromas. Occasionally, stir gently to prevent ingredients from sticking to the bottom of the pan.
Step 5: Final Touches
After 30 minutes, remove and discard the bay leaf from the soup. Stir in 2 cups of shredded fresh spinach and cook for an additional 3-4 minutes until the spinach has wilted and added vibrant color. Your Hearty White Bean Fennel Soup is now packed with nutrients and ready to serve!
Step 6: Serve and Enjoy
Ladle the soup into bowls while it’s still warm for the best flavor. Consider topping each serving with freshly grated Parmesan cheese or a sprinkle of chili flakes for an extra touch. This delicious Fennel Soup can be savored alone or paired with crusty bread for a complete meal.

Make Ahead Options
This Hearty White Bean Fennel Soup is an exceptional choice for meal prep, saving you time on those busy weeknights! You can chop the onion and fennel bulbs up to 24 hours in advance, storing them in an airtight container in the refrigerator to keep them fresh. The soup can also be fully prepared and stored in the fridge for up to 3 days. When you’re ready to enjoy it, simply reheat the soup on the stove over medium heat, adding the fresh spinach just before serving to ensure it stays vibrant and tender.

Hearty White Bean Fennel Soup Recipe FAQs
What is the best way to select fennel for this soup?
Absolutely! Look for fennel bulbs that are firm, heavy, and have a bright white or light green color. Avoid any with brown spots or wilting leaves, as these are signs of aging. Fresh fennel should also have a clean, anise-like scent; the more fragrant, the better for your soup!
How should I store leftover fennel soup?
To keep your Hearty White Bean Fennel Soup fresh, transfer leftovers to airtight containers and store them in the refrigerator for up to 4-5 days. Allow the soup to cool completely before sealing, which helps maintain its flavor and texture.
Can I freeze fennel soup, and if so, how?
Very easy! You can freeze your soup without the spinach for up to 3 months. Before freezing, allow the soup to cool completely, then pour it into freezer-safe containers or heavy-duty freezer bags, leaving some space for expansion. When ready to enjoy, thaw in the refrigerator overnight and reheat on the stove, stirring in fresh spinach just before serving.
What should I do if my soup turns out watery?
If your soup ends up too watery, don’t worry! You can thicken it by simmering it uncovered for an additional 10-15 minutes to allow some of the liquid to evaporate.

Should I remove the bay leaf before serving?
Yes! Always remember to remove the bay leaf before serving your soup, as it is not edible and can have a hard, off-putting texture. After simmering, just fish it out with a spoon or use a slotted spoon to easily remove it from the pot. Enjoy your beautifully flavorful fennel soup!
