How to Make Italian Pastina Penicillin Soup Recipe
Step 1: Sauté the Aromatics
Begin by heating the butter and olive oil over medium heat in a large pot. As the butter melts and bubbles, add the chopped onion, diced carrots, and celery along with a pinch of salt. Stir occasionally and let everything soften gently for 6 to 8 minutes until the onion turns translucent and the vegetables release their sweet aroma. This step builds the savory backbone of the soup.
Step 2: Add Garlic and Liquids
Next, toss in the minced garlic and cook it for just about 30 seconds to a minute. The goal is to coax out its fragrance without browning it. Then pour in the chicken broth and water, scraping the pot’s bottom to lift any flavorful bits stuck there. Add your dried Italian seasoning or oregano, black pepper, and the optional crushed red pepper flakes – these seasonings bring complexity and warmth to the broth.
Step 3: Simmer and Infuse Flavors
Bring the soup to a gentle boil and then lower the heat to allow it to simmer for 5 to 10 minutes. This quiet bubbling lets all those flavors mingle and deepen, setting the stage for the tender pasta to shine.
Step 4: Cook the Pastina
Stir in the pastina pasta and continue simmering while stirring frequently for 5 to 8 minutes. You want the pasta just tender but not mushy, and the broth should thicken slightly to a beautiful, cozy consistency.
Step 5: Temper the Eggs and Parmesan
In a medium bowl, whisk together the eggs and grated Parmesan until smooth. To avoid curdling, ladle a small amount of hot broth into the egg mixture while whisking vigorously. Then slowly pour this warmed egg and cheese mixture back into the pot, stirring constantly. The broth will become luxuriously silky, the signature texture that makes this Italian Pastina Penicillin Soup Recipe unforgettable.
Step 6: Final Touches
Finish off your soup by stirring in fresh lemon juice and chopped parsley for brightness and freshness. Taste and adjust the seasoning with more salt, pepper, or lemon juice if you want a little extra zing. If the soup feels too thick, simply loosen it with a bit of hot water or broth to reach your preferred consistency.
Step 7: Serve and Enjoy
Ladle the soup into bowls and, if you like, sprinkle extra Parmesan cheese and parsley on top for added flavor and a pop of color. Serve it warm and dive right into this soul-nourishing classic.
How to Serve Italian Pastina Penicillin Soup Recipe
Garnishes
A little sprinkle of freshly grated Parmesan and chopped parsley right before serving takes this soup to the next level. A crack of black pepper or a light drizzle of good olive oil provides an elegant finishing touch without overwhelming the delicate flavors. These simple garnishes elevate each spoonful and make every bowl inviting.
Side Dishes
This soup pairs beautifully with crusty bread or garlic toast that soaks up every drop of the flavorful broth. A simple green salad with a zesty vinaigrette complements the richness, making for a well-rounded meal. You could also serve it alongside roasted vegetables for a comforting, wholesome dinner.
Creative Ways to Present
For a more festive presentation, try serving the soup in small, pretty bowls as an appetizer at a dinner party. You could swirl in a tiny dollop of pesto or a few fresh basil leaves for a contemporary twist. Another fun idea is to top individual bowls with crispy pancetta or toasted pine nuts for added texture and flavor complexity.
Make Ahead and Storage
Storing Leftovers
This Italian Pastina Penicillin Soup Recipe stores wonderfully in an airtight container in the refrigerator for up to 3 days. Keep in mind the pasta may absorb some broth and thicken the soup, but you can easily adjust the texture when reheating by adding a splash of broth or water.
Freezing
Freezing homemade soups with pasta can be tricky since the pasta may become mushy after thawing. If you plan to freeze, store the cooked broth and vegetables separately from the pastina. Freeze in separate containers and combine them when reheating to keep textures just right.
Reheating
Reheat gently on the stovetop over low heat, stirring often. Add a bit of broth or water if the soup is too thick. Avoid boiling to preserve the silky texture from the eggs. Reheating this soup slowly helps maintain its creamy, comforting essence every time.
FAQs
What is pastina, and can I use another pasta?
Pastina is a tiny pasta, often star-shaped or like little pearls, that cooks quickly and adds delicate texture to soups. If you don’t have pastina, you can substitute orzo, acini di pepe, or other small pasta shapes, keeping in mind they may alter the cooking time.
Why are eggs added to the soup?
The eggs, combined with Parmesan, create the silky, velvety texture characteristic of this Italian Pastina Penicillin Soup Recipe. They enrich the broth and add extra protein, turning simple ingredients into something truly comforting.
Can I make this soup vegetarian?
Absolutely! Swap the chicken broth for vegetable broth, and be mindful to choose a vegetarian Parmesan or a similar cheese alternative to keep it fully vegetarian while maintaining great flavor.
How long does it take to make this soup?
This recipe takes about 35 minutes from start to finish, making it quick enough for a cozy weeknight meal but flavorful and satisfying enough to enjoy any time you need a comforting pick-me-up.
What does “Penicillin” mean in this soup’s name?
It’s a fun nickname highlighting how this soup can act like a gentle, healing remedy when you’re feeling under the weather—warm, soothing, and packed with immune-boosting ingredients like garlic and lemon.

- 3 cloves garlic, minced
Broth and Seasonings
- 8 cups low-sodium chicken broth

- 1/2 teaspoon black pepper
- 1/2 teaspoon dried Italian seasoning or dried oregano

Enrichment and Garnish
- 2 large eggs
- 1 cup finely grated Parmesan cheese
- 2 tablespoons fresh lemon juice
- 2 tablespoons chopped fresh parsley, plus more for serving
Instructions
- Sauté the Vegetables: In a large pot, heat the butter and olive oil over medium heat until the butter melts and begins to foam. Add the onion, carrots, and celery with a pinch of salt and cook for 6–8 minutes, stirring occasionally, until the vegetables are softened and the onion is translucent.
- Add Garlic: Stir in the minced garlic and cook for 30 seconds to 1 minute, just until fragrant, being careful not to let it brown.
- Add Broth and Seasonings: Pour in the chicken broth and water, scraping up any bits from the bottom of the pot for extra flavor. Add the Italian seasoning, black pepper, and crushed red pepper flakes if using.
- Simmer the Soup: Bring the soup to a gentle boil, then reduce the heat and let it simmer for 5–10 minutes so the flavors meld together.
- Cook the Pastina: Stir in the pastina pasta and simmer, stirring frequently, for 5–8 minutes or until the pasta is just tender and the broth has thickened slightly.
- Prepare Egg Parmesan Mixture: While the pastina cooks, whisk the eggs and grated Parmesan cheese together in a medium bowl until smooth.
- Temper the Eggs: Turn the heat to low so the soup is hot but not boiling. Ladle a small amount of hot broth into the egg mixture slowly while whisking constantly. This tempers the eggs to prevent curdling.
- Incorporate the Egg Mixture: Slowly pour the warmed egg mixture back into the pot in a thin stream, stirring constantly until the broth becomes slightly thickened and silky in texture.
- Add Lemon and Parsley: Stir in the fresh lemon juice and chopped parsley. Taste the soup and adjust seasoning with additional salt, pepper, or lemon juice as needed.
- Adjust Consistency: If the soup is thicker than desired, add a splash of hot water or broth to loosen it to your preferred consistency.
- Serve: Ladle the soup into bowls and serve warm. Garnish with extra Parmesan cheese and parsley if desired for added flavor and presentation.
Notes
- Use low-sodium broth to better control salt levels in the soup.

- Pastina cooks quickly; monitor it closely to prevent overcooking and mushiness.
- For a vegetarian option, substitute vegetable broth and omit eggs and Parmesan or use vegetarian alternatives.
- This soup can be stored in the refrigerator for up to 3 days and reheated gently on the stove.
- Add crushed red pepper flakes according to your preferred spice level or omit for mild flavor.
