How to Make Italian Penicillin Soup (Italian Pastina Soup) Recipe

Step 1: Simmer the Broth and Vegetables

Start by pouring your chicken broth into a large pot and bringing it to a gentle boil. Next, add the chopped onion, carrots, celery, garlic cloves, and that all-important parmesan rind. Let everything simmer for about 25 minutes. This slow cooking allows the broth to absorb the rich flavors from the vegetables and the parmesan rind, creating a base that’s irresistible in depth and warmth.

Step 2: Puree the Vegetables

Once the veggies are tender, carefully remove the parmesan rind and discard it. Use a slotted spoon to scoop out the softened vegetables and place them into a blender along with around 2 cups of the broth. Let the mixture cool just enough to be safe to blend, then whirl it into a thick, creamy puree. This step transforms ordinary broth and veggies into a luxurious, silky texture that’s the heart and soul of this soup.

Step 3: Combine and Cook the Pastina

Pour your freshly blended vegetable puree back into the pot with the remaining broth and stir it well to combine. Now, add your pastina or any tiny pasta variety you prefer. Simmer until the pasta is cooked through and tender, which usually takes just a few minutes. This tender little pasta adds comfort and substance, perfectly soaking up those rich flavors.

Step 4: Final Touches and Serving

Once your soup is ready, ladle it into warm bowls. Sprinkle with fresh parsley and a generous handful of grated parmesan to finish. These garnishes add bursts of freshness and that signature cheesy aroma that make every spoonful irresistible.

How to Serve Italian Penicillin Soup (Italian Pastina Soup) Recipe

Garnishes

Fresh parsley and grated parmesan are classic, but don’t be shy about adding a sprinkle of crushed red pepper flakes for a subtle kick or a drizzle of good olive oil for extra silkiness. These small touches enhance the comforting, layered flavors and add visual appeal.

Side Dishes

Pair this soup with crusty Italian bread or garlic toast to soak up every last bit of the flavorful broth. A crisp green salad with a light vinaigrette also complements the richness of the soup, creating a perfectly balanced meal.

Creative Ways to Present

For a charming rustic presentation, serve the soup in individual ceramic bowls garnished with herb sprigs. You can even float small parmesan crisps on top to add texture and a gourmet flair that will wow your guests at any gathering.

Make Ahead and Storage

Storing Leftovers

This soup stores beautifully in the refrigerator for up to 3 days. Transfer leftover soup to an airtight container and keep it chilled. The flavors actually deepen after a day or two, making it even better the next time you enjoy it.

Freezing

You can freeze Italian Penicillin Soup for longer storage, but it’s best to freeze without the pastina. Pasta can become mushy after freezing and reheating. When ready to eat, thaw the soup and add freshly cooked pastina before serving to maintain perfect texture.

Reheating

Reheat gently on the stove over low heat, stirring occasionally until warmed through. If the soup has thickened too much, simply add a splash of broth or water to loosen it up. For perfect results, add fresh pasta after reheating.

FAQs

Can I make Italian Penicillin Soup vegetarian?

Absolutely! Swap the chicken broth for a rich vegetable broth and omit the parmesan rind if you want to keep it fully vegetarian, or use a vegetarian parmesan alternative. It still turns out deliciously comforting and flavorful.

What type of pasta works best instead of pastina?

Any tiny pasta shape like acini di pepe, orzo, or tiny stars can be used. The key is to choose small shapes that cook quickly and hold onto the broth, giving you those delightful little bites throughout the soup.

Why do we add a parmesan rind?

The parmesan rind adds an incredible depth of umami and richness to the broth. It melts slowly during cooking, infusing the soup with its unique flavor and creating a silky mouthfeel that is signature to this recipe.

Can I prepare this soup in advance?

Yes! The soup base can be made ahead and refrigerated. Add the pasta just before serving to keep it from getting too soft. This makes it perfect for busy weeknights or when hosting guests.

How spicy is the soup?

The classic recipe is mild and soothing, but you can easily add a pinch of crushed red pepper flakes or a dash of black pepper to bring in some gentle heat according to your taste.
