The Secrets of a Successful Soup: Choosing Ingredients and Preparation

Ingredients Required (Serves 4)

  • 1 medium onion  : Choose a yellow onion, slightly sweet, which will provide a balanced aromatic base.
  • 4 garlic cloves  : Fresh and juicy, they add a savory depth. Save 2 extra cloves for a bold finishing touch.
  • 1 medium carrot  : Choose a firm, colorful one for a natural sweet note.
  • 2 medium potatoes  : Choose floury varieties like Bintje, which break down slightly when cooked, thickening the soup.
  • 2 medium zucchinis  : Young and shiny, they guarantee tender flesh without bitterness.
  • 30 grams of butter  : Butter provides incomparable creaminess, but for a vegan version, replace it with olive oil.
  • Salt, black pepper and red pepper  : Red pepper (or paprika) adds a typically Spanish smoky sweetness.
  • 700 ml water  : Use homemade vegetable stock to intensify the flavors.
  • Juice of half a lemon  : A hint of acidity to awaken the aromas.
  • Fresh coriander and dill  : These herbs add freshness and lightness. Mint garnish adds a vibrant touch.
  • 1 tablespoon of heavy cream  : For a velvety finish.

Preparation Steps: A Ballet of Flavors

Step 1: Preparing the Vegetables – The Foundation of a Good Soup

Start by carefully peeling the vegetables.  The onion  is diced (very finely) so that it blends harmoniously into the soup.  The garlic  is finely chopped, releasing its powerful aromas as soon as it cooks.  The carrot  and  potatoes  are cut into regular cubes for even cooking.  The zucchini , meanwhile, can be cut into thick rounds or cubes, depending on whether you want a more rustic texture or a completely smooth one after blending.

Pro Tip  : To prevent potatoes from oxidizing, immerse them in a bowl of cold water after peeling.


Step 2: Awakening the Aromas – The Initial Sauté

In a cast iron pot or large saucepan, melt the  butter  over medium-low heat. When it begins to foam, add the onion  and cook for 3-4 minutes until translucent.  Don’t let it brown  , as this will make the soup bitter. Then stir in the garlic ,  carrot  , and  potatoes . Stir gently to coat the vegetables in the butter. This “sweating” step (gently cooking without browning) allows the vegetables to release their juices slowly, creating a rich base.

Seasoning  : Add salt moderately (adjust at the end of cooking), a pinch of  black pepper  and half a teaspoon of  red pepper  for a warm but not spicy note.


Step 3: Slow Cooking – The Alchemy of Flavors

Pour in the  700 ml of water  (or stock) and bring to a simmer. Cover and simmer for 10 minutes over low heat. The potatoes should begin to soften, but not fall apart.  Check for doneness  by lightly piercing a potato with the tip of a knife.

Why not use zucchini from the start?  Zucchini cooks quickly, so adding it as a second step preserves its vibrant color and tender texture.


Step 4: Incorporating the Zucchini – Freshness and Balance

Add the  zucchini  and  2 additional cloves of garlic , roughly crushed. The extra garlic adds a surprising intensity, typical of Iberian recipes. Cook for 5 to 7 minutes, until the zucchini is tender but still slightly firm.  Avoid prolonged cooking  to avoid altering their delicate flavor.


Step 5: Mixing – Creating Smoothness

Remove from heat and blend the soup with an  immersion blender  until smooth. For a more rustic version, blend only partially, leaving some vegetable pieces. If the soup is too thick, add a little hot water.

Gourmet Alternative  : For an ultra-smooth, strain the soup through a fine sieve. This step, although optional, removes fibers and creates a silky texture.


Step 6: Finishing Touches – Radiance and Freshness

Off the heat, stir in the  lemon juice , which balances the richness of the butter and enhances the herbs. Add the  chopped cilantro  and dill  .  Why not cook the herbs?  The heat of the soup is enough to release their essential oils without wilting them.


Step 7: The Presentation – A Visual Feast

Pour the soup into warmed bowls. Place a dollop of  crème fraîche  in the center, then swirl the soup with a spoon for a marbled effect. Sprinkle with  mint leaves , fresh dill  , and  toasted pumpkin seeds  for a crunch. A drizzle of extra virgin olive oil  adds a fruity touch.


Variations and Customizations: Adapt the Recipe to Your Desires

  1. Vegan Version  :
    • Replace the butter with 2 tablespoons of olive oil.
    • Substitute crème fraîche with coconut yogurt or homemade almond cream.
  2. Gourmet Additions  :
    • Stir in 100g of  crumbled feta  before serving for a salty touch.
    • Add 50g of  cooked red lentils  for a heartier version.
  3. Spice Madness  :
    • For a Moroccan twist, add 1 teaspoon of  cumin  and a pinch of  cinnamon  when cooking vegetables.

Storage and Serving Tips

  • Storage  : The soup can be stored for 3 days in the refrigerator in an airtight container. Reheat over low heat, stirring to prevent it from sticking.
  • Freezing  : Freeze in ice cube trays for individual servings. Defrost slowly in the refrigerator before reheating.
  • Sides  : Serve with  garlic croutons ,  raw zucchini sticks  for crunch, or a slice of  toasted sourdough bread  .

This soup is a concentrate of benefits:

  • Zucchini  : Rich in water and fiber, they aid digestion.

History and Origin: A Recipe with Spanish Roots

This recipe was passed on to me by a friend in Valencia, where light and fragrant soups are a must. In Spain,  sopa de calabacín  is often topped with  Serrano ham  or  smoked paprika  (pimentón). This version, though simplified, retains its Mediterranean soul thanks to generous garlic and fresh herbs.
