Key Ingredients
To craft this classic, you will need only a handful of essential components. Each ingredient plays a crucial role in achieving the signature comforting profile of this soup.
* 6 cups Chicken broth: The foundation of flavor and warmth.
* 1 cup Pearl pasta: Small, tender pasta shapes, such as acini di pepe, that cook quickly and are easy to consume.
* 2 large Eggs: Beaten and slowly introduced to create delicate ribbons of protein.
* 0.5 cup Parmesan cheese: Adds a savory, umami depth and richness.
* 1 Lemon, sliced: Provides a bright, zesty counterpoint that elevates the overall taste.
* 2 tbsp Fresh parsley: Offers a touch of freshness and vibrant color.
* 0.5 tsp Black pepper: A subtle hint of spice to round out the flavors.
These precise quantities ensure a balanced and flavorful soup, true to its traditional form.
Step-by-Step Cooking Instructions
Crafting this restorative soup is a straightforward process, demanding minimal effort for maximum comfort. Follow these steps for a perfect bowl every time.
Boiling the Broth
Begin by pouring 6 cups of chicken broth into a medium to large saucepan. Place the saucepan over medium-high heat. Bring the broth to a strong, rolling boil. This ensures the pasta will cook quickly and evenly.

Cooking the Pasta
Once the broth is vigorously boiling, stir in 1 cup of pearl pasta. Keep stirring occasionally to prevent the tiny pasta from sticking to the bottom of the pan. Cook the pasta according to package directions, which is typically until it is tender but still retains a slight bite. For most pearl pasta, this will take approximately 6 to 8 minutes. Taste a piece of pasta to ensure it has reached your desired tenderness.
The Egg Drop Technique
Once the pasta is cooked, reduce the heat to a gentle simmer. While the broth is simmering, take the 2 large eggs that have been lightly beaten. Slowly pour the beaten egg mixture into the simmering broth. As you pour, gently stir the broth with a fork or a whisk. This technique creates delicate, wispy strands of cooked egg throughout the soup, characteristic of Italian egg drop soup. The egg will cook almost instantly in the hot broth.

Finishing with Lemon and Herbs
Remove the saucepan from the heat immediately after the egg has cooked. This prevents the pasta from becoming overcooked and ensures the broth retains its clarity. Stir in the 0.5 cup of Parmesan cheese until it melts and integrates into the broth. Next, add the 1 sliced lemon, allowing its bright citrus notes to infuse the soup. Finally, stir in 2 tablespoons of fresh parsley and 0.5 teaspoon of black pepper. Serve the soup hot, ensuring each bowl gets a little bit of everything: broth, pasta, egg, and a hint of fresh lemon and parsley.
Tips for the Best Results
Achieving the perfect Italian Penicillin Soup involves paying attention to a few key details that can significantly enhance its taste and texture.
* Broth Quality: The chicken broth is the backbone of this soup. Using a high-quality, flavorful chicken broth, whether homemade or store-bought, will make a substantial difference. Look for low-sodium options if you prefer to control the salt content yourself.
* Pasta Perfection: Do not overcook the pearl pasta. It should be tender but not mushy. Tiny pasta shapes like acini di pepe cook very quickly, so monitor it closely during the 6 to 8 minutes of cooking time. The pasta will continue to absorb liquid even after the soup is removed from the heat, so slightly al dente is ideal for immediate serving.
* Egg Whisking: Ensure the eggs are well-beaten before slowly drizzling them into the simmering broth. This helps create those fine, delicate ribbons rather than large clumps. A fork or whisk can be used to gently stir the broth as you pour, distributing the egg evenly.
* Lemon Freshness: The 1 sliced lemon is not merely a garnish. Its fresh, bright acidity cuts through the richness of the broth and Parmesan, adding a crucial layer of flavor. Do not skip this ingredient. A fresh lemon offers a much more vibrant taste than bottled lemon juice.
* Parmesan Integration: Stir the 0.5 cup of Parmesan cheese until it fully melts into the broth. This creates a creamy texture and savory depth without making the soup heavy. Grating your own Parmesan cheese yields superior flavor compared to pre-shredded varieties.
* Serve Immediately: While comforting, this soup is best enjoyed right after preparation. The pasta can continue to absorb the broth and swell over time, changing the texture.
Storage and Reheating
While Italian Penicillin Soup is best served fresh, sometimes there are leftovers. Proper storage and reheating can help maintain its comforting qualities.
* Storage: Allow the soup to cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 2-3 days. Be aware that the pearl pasta will continue to absorb the broth during storage, becoming softer and potentially swelling.
* Reheating: To reheat, gently warm the soup in a saucepan over low to medium heat on the stovetop. Stir occasionally until it is heated through. You may find the soup has thickened considerably due to the pasta absorbing liquid. If it is too thick, you can add a small amount of extra chicken broth or water to achieve your desired consistency. Avoid boiling the soup vigorously during reheating, as this can further overcook the pasta and egg.
* Fresh Garnish: When reheating, it is always a good idea to add a fresh squeeze of lemon juice and a sprinkle of fresh parsley and Parmesan cheese to revive the flavors and presentation. This helps bring back the vibrancy of the freshly made soup.
This simple yet profound Italian Penicillin Soup offers more than just sustenance; it offers a tradition of care, warmth, and flavor that speaks volumes. It’s a fundamental part of Italian comfort cooking, ready to soothe and restore whenever you need it most.
