How to Make Watercress Soup with Grana Padano and San Daniele Prosciutto Tartines Recipe

Step 1: Prepare Your Prosciutto di San Daniele

Start by removing the Prosciutto di San Daniele from the refrigerator and letting it come to room temperature for about half an hour. This small detail intensifies its aroma and richness, allowing it to shine on your tartines without being too cold or chewy.

Step 2: Sauté the Vegetables

Melt the butter in a heavy-based soup pan over medium-high heat. Add the broccoli florets, sliced leeks, and finely chopped garlic, cooking them gently for 5 minutes. This step softens the vegetables and releases their natural flavors, setting a savory foundation for the soup.

Step 3: Add Watercress

Toss in the vibrant watercress and cook for an additional minute. This fragile leafy green wilts quickly, infusing the soup with its distinct, peppery brightness that sets it apart from ordinary green soups.

Step 4: Simmer with Stock and Cheese Rind

Pour in the vegetable stock and add the Grana Padano cheese rind. Lower the heat to medium and cover the pot with a lid. Let everything simmer gently for 15 to 20 minutes until the broccoli, leeks, and watercress are tender and have blended flavors.

Step 5: Blend and Enrich

Use a hand blender to puree the soup until perfectly smooth. Stir in the double cream for a luxuriously creamy texture that will complement the crisp tartines beautifully. This final step elevates the soup’s flavor and presentation.

Step 6: Prepare the Tartines

Drizzle some good quality olive oil on the cooled sourdough toasts. Then, neatly layer the room-temperature Prosciutto di San Daniele on top. This combination adds satisfying crunch paired with silky, savory notes to your meal.

Step 7: Serve with Flair

Ladle the soup into bowls, sprinkle freshly grated nutmeg and extra Grana Padano cheese over each serving. Present immediately alongside your delicious tartines for a meal that looks as good as it tastes.

Garnishes

Garnishing the soup with freshly grated nutmeg and extra Grana Padano enhances each spoonful with aromatic warmth and sharp cheesy bursts. This final flourish transforms your bowl from comforting to downright irresistible.

Side Dishes

Serve this soup and tartine duo alongside a crisp mixed green salad or a bright cucumber and radish salad to add refreshing crunch and balance. The contrast in textures and flavors keeps the meal light yet fulfilling.

Creative Ways to Present

For special occasions, consider serving the tartines open-faced on wooden boards with delicate edible flowers for visual appeal. Another idea is to swirl a drizzle of herb oil or a touch of chili oil into the soup before serving to add color and subtle flavor twists.

Make Ahead and Storage

Storing Leftovers

You can keep the leftover soup in an airtight container in the refrigerator for up to 2 days. To keep the vibrant green color, cool the soup quickly before storing and cover it tightly.

Freezing

This watercress soup freezes well for up to 3 months. However, be aware that the texture of the cream might separate slightly upon thawing. Gently reheating and stirring can help restore its smoothness.

Reheating

Warm the soup slowly over low heat to maintain its delicate flavors and creamy texture. Avoid boiling as it can dull the freshness of the watercress and cause the cream to curdle. The tartines are best prepared fresh, as their crispiness does not retain well.

FAQs

Can I use a different cheese if I don’t have Grana Padano?

Absolutely! Parmesan is a great substitute that still provides a similar nutty and salty depth to the soup. Just be sure to use a good-quality cheese rind to infuse the stock.

Is Prosciutto di San Daniele necessary for the tartines?

While this specific prosciutto adds a unique silky texture and nuanced flavor, any high-quality cured ham or prosciutto will work well if you cannot find San Daniele.

Can I make this soup vegan or dairy-free?

To create a dairy-free version, swap the butter and double cream for plant-based alternatives like olive oil and coconut cream. The soup will still be delicious, though the texture and flavor will be slightly different.

What is the best way to toast sourdough for the tartines?

Toast your sourdough slices until golden and crisp but not burnt, then allow them to cool completely to ensure they stay crunchy when topped with prosciutto and olive oil.

Can I prepare the soup in advance for entertaining?

Yes! The soup can be made a day ahead and gently reheated before serving. However, prepare and assemble the tartines just before serving to keep them crisp and fresh.
