How to Make Fennel Soup with Cannellini Beans and Spinach Recipe

Step 1: Sauté the Onion and Fennel

Start by heating the olive oil in a large saucepan over medium heat. Toss in the chopped onion and thinly sliced fennel bulb. Sauté these until they start to soften and the onion becomes translucent. This step unlocks their natural sweetness and lays the perfect aromatic foundation for the soup.

Step 2: Add Broth and Seasonings

Pour in the chicken broth or vegetable broth, then add the rinsed cannellini beans and undrained diced tomatoes. Sprinkle in dried thyme, pepper, and drop in the bay leaf. Give everything a gentle stir so the flavors begin to mingle.

Step 3: Simmer to Tenderness

Bring the soup to a boil, then reduce the heat to low, cover the pot, and allow it to simmer slowly for about 30 minutes. During this time, the fennel softens completely, releasing its lovely flavor into the broth while all the ingredients marry into one harmonious taste.

Step 4: Add Spinach and Finish

Remove the bay leaf and discard it. Stir in the shredded fresh spinach, cooking for another three to four minutes until the spinach wilts and the soup looks vibrant and inviting. Now it’s ready to serve piping hot.

Garnishes

Boost the flavor and presentation by adding a sprinkle of freshly grated Parmesan or a drizzle of high-quality extra virgin olive oil. A few fresh thyme leaves or a twist of lemon zest can also brighten the bowl just before serving, making every spoonful exciting.

Side Dishes

This soup is fantastic on its own but pairs beautifully with crusty artisan bread or garlic toast for dipping. A simple mixed green salad with lemon vinaigrette complements the freshness of the soup for a well-rounded meal.

Creative Ways to Present

If you're serving guests, ladle the soup into small, shallow bowls and garnish with a sprig of thyme and a lemon wedge on the side. For a rustic feel, serve it in a bread bowl. You can also swirl in a dollop of herbed Greek yogurt or sour cream for a creamy contrast that’s visually appealing.
