Italian-Style Lentil Vegetable Soup (Zuppa di Lenticchie)

Yields: 6-8 servings
Prep time: 20 minutes
Cook time: 45-50 minutes

Ingredients

The Soffritto (Flavor Base):

• 3 tbsp extra virgin olive oil, plus more for drizzling

• 1 medium onion, finely diced

• 2 medium carrots, finely diced

• 2 celery stalks, finely diced

• 4 cloves garlic, minced

The Soup:

• 1½ cups (300g) dried brown or green lentils, rinsed and picked over

• 1 can (14 oz / 400g) diced tomatoes, with their juices

• 6 cups vegetable broth (or chicken broth for non-vegetarian)

• 2 cups water

• 1 medium zucchini, diced

• 1 medium potato, peeled and diced small

• 1 bay leaf

• 1 tsp dried oregano

• ½ tsp dried thyme

• 1 small Parmesan rind (optional, but highly recommended)

• Salt and freshly ground black pepper, to taste

To Finish:

• 2 cups fresh spinach or kale, roughly chopped

• 1 tbsp fresh lemon juice or red wine vinegar

• Freshly grated Parmesan cheese, for serving

• Crusty bread, for serving

Instructions

1. Sauté the Soffritto: Heat the olive oil in a large, heavy-bottomed pot or Dutch oven over medium heat. Add the diced onion, carrots, and celery. Cook, stirring occasionally, for 8-10 minutes until softened and the onion is translucent. Add the minced garlic and cook for 1 more minute until fragrant.

2. Toast the Lentils: Add the rinsed lentils to the pot and stir to coat them in the oil and vegetables. Cook for 1-2 minutes. This step helps the lentils hold their shape and adds a subtle nutty flavor.

3. Simmer the Soup: Add the diced tomatoes (with their juices), vegetable broth, water, diced zucchini, diced potato, bay leaf, oregano, and thyme. If using a Parmesan rind, drop it in now. Stir everything together and bring to a boil.

4. Cook Until Tender: Once boiling, reduce the heat to low, cover partially with a lid, and let it simmer gently for 35-40 minutes, or until the lentils are tender but not mushy. Stir occasionally to prevent sticking, and add more water or broth if the soup becomes too thick for your liking.

5. Finish the Soup: Remove the bay leaf and Parmesan rind. Stir in the chopped spinach or kale and let it wilt for 2-3 minutes. Add the lemon juice or vinegar—this brightens all the flavors. Taste and season generously with salt and freshly ground black pepper.

6. Serve: Ladle the soup into warm bowls. Finish with a generous drizzle of good olive oil, a heap of freshly grated Parmesan cheese, and crusty bread on the side for dipping.

Tips for the Best Lentil Soup

• Lentil Choice Matters: Use standard brown or green lentils. They hold their shape beautifully and give the soup a hearty texture. Avoid red lentils, which will break down into a purée (unless you want a creamier soup).

• The Parmesan Rind Trick: A hard, waxy Parmesan rind infuses the broth with an incredible savory, nutty depth as it simmers. It’s a classic Italian trick for soups and stews. Just fish it out before serving.

• Make It Heartier: For a more substantial meal, stir in a cup of cooked small pasta like ditalini or broken spaghetti during the last 10 minutes of cooking.

• Flavor Deepens Overnight: This soup is famously better the next day. The flavors meld together beautifully in the refrigerator. It will thicken considerably, so you may need to thin it with a splash of broth or water when reheating.

• Vegetarian/Vegan Option: The soup is naturally vegetarian. For a vegan version, simply omit the Parmesan rind and cheese garnish, or use a vegan Parmesan alternative.
