Simple ingredients combine beautifully in this recipe, each one playing a crucial role in building the rich, layered taste and comforting texture of the Italian Penicillin Soup. From the sweet onions that bring subtle depth, to the creamy cheese rind adding savory richness, every component is essential.

• 8 cups lower-sodium chicken broth: The flavorful liquid base that carries all the wonderful tastes together without overpowering.
• 2 cups chopped sweet onion: Adds a gentle sweetness and body to the soup’s foundation.
• 1 ½ cups peeled and coarsely chopped carrots: Provide natural sweetness and vibrant color.
• 2 celery ribs, coarsely chopped: Give a subtle earthiness and balance the sweetness.
• 6 garlic cloves, smashed and peeled: Infuse the soup with a savory warmth and depth.
• ¾ teaspoon kosher salt: Enhances all the natural flavors without making it salty.
• 4 thyme sprigs: Introduce bright, herbal notes that awaken the palate.
• 2 fresh bay leaves: Impart a hint of aromatic complexity.
• 1 (2 ounce) Parmigiano-Reggiano cheese rind: Adds a luxurious, nutty umami that’s totally unique.
• 4 ounces uncooked pastina pasta: Tender and petite pasta that soaks up the broth beautifully.
• 2 cups shredded rotisserie chicken: Convenient, juicy protein that takes the soup to satisfying heights.
• Fresh flat-leaf parsley leaves: For a pop of color and fresh herbal brightness at the end.

How to Make Italian Penicillin Soup

Step 1: Build the Flavor Base

Start by bringing the chicken broth, chopped sweet onion, carrots, celery, garlic, and kosher salt to a boil in a large saucepan or Dutch oven. Once boiling, reduce the heat to medium-low and let the vegetables gently simmer for about 10 minutes. This softens them perfectly while infusing the broth with their natural sweetness and savory notes, creating that essential flavor depth that makes the Italian Penicillin Soup so comforting.

Step 2: Blend to Silky Perfection

After the vegetables have softened, carefully use a slotted spoon to transfer them along with one cup of the broth into a blender. Blend the mixture until completely smooth—this step is the secret magic that gives the soup its luscious, velvety texture. Be sure to remove the blender lid’s center piece to allow steam to escape, and cover the top with a clean kitchen towel to avoid splatters. Stir this fragrant carrot puree back into the pot to marry all the flavors.

Step 3: Add Herbs, Cheese, and Pasta

Next, add the thyme sprigs, fresh bay leaves, and that priceless Parmigiano-Reggiano rind to the pot. Bring the soup back to a gentle boil before adding the uncooked pastina pasta. Reduce the heat to medium-low and let the soup simmer for 18 to 20 minutes, stirring occasionally. This slow simmer lets the pasta cook perfectly and the cheese rind releases its signature savory richness into the broth.

Step 4: Finish with Chicken

In the last three minutes of cooking, stir in the shredded rotisserie chicken to warm through without drying out. When done, remove the pot from heat and fish out the thyme sprigs, bay leaves, and cheese rind. This leaves you with an incredibly flavorful, silky broth brimming with tender chicken and pasta.

How to Serve Italian Penicillin Soup

Garnishes

To truly elevate your bowl, sprinkle freshly grated Parmigiano-Reggiano cheese on top and scatter some fresh flat-leaf parsley leaves. The cheese adds a touch of creamy saltiness while the parsley brightens and adds a fresh herbaceous kick, giving every spoonful a lovely contrast of richness and freshness.

Side Dishes

This soup shines wonderfully on its own, but pairing it with warm, crusty Italian bread or a light arugula salad with lemon vinaigrette makes for an inviting and balanced meal. The bread is perfect for dipping, soaking up all that flavorful broth, while the salad refreshes your palate.

Creative Ways to Present

For a special dinner, serve the Italian Penicillin Soup in rustic ceramic bowls with a drizzle of good-quality extra virgin olive oil and a few cracks of black pepper. You can even top with a toasted sprinkle of pine nuts or chili flakes for an unexpected twist. This creates a feast for the eyes as well as the taste buds!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer leftover Italian Penicillin Soup into an airtight container and refrigerate for up to 3 days. The flavors develop even more overnight, making reheated soup taste just as delicious and comforting the next day.

Freezing

This soup freezes beautifully. For best results, pack it into freezer-safe containers, leaving room for expansion, and freeze for up to 2 months. Note that the pasta may absorb some broth during freezing, so you might want to undercook it slightly when preparing if freezing is planned.

Reheating

Reheat gently on the stovetop over low to medium heat, stirring occasionally. If the soup has thickened too much overnight or after freezing, stir in a splash of chicken broth or water to loosen it up to your preferred consistency.

FAQs

What makes Italian Penicillin Soup different from regular chicken noodle soup?

The key difference lies in blending some of the cooked vegetables for a silky texture and the addition of a Parmigiano-Reggiano cheese rind, which brings a unique umami richness. These touches give it a luxurious depth compared to ordinary broth-based soups.

Can I use homemade chicken broth for this recipe?

Absolutely! Homemade chicken broth adds even more flavor and personalization to your Italian Penicillin Soup, making it taste fresh and wholesome. Just be sure it’s lower in salt to control seasoning more easily.

What if I can’t find pastina pasta?

If pastina isn’t available, you can substitute with other small pasta shapes like orzo, acini di pepe, or even broken-up small shells. The tiny size is important so the pasta cooks quickly and blends wonderfully with the silky soup.

Can I make this soup vegetarian?

This recipe is designed as a chicken soup, but you could make a delicious vegetarian version by substituting vegetable broth, skipping the chicken, and adding hearty mushrooms or white beans for protein. However, the Parmesan rind still adds a subtle meatiness, so keep that in mind.

Is there a way to make this soup creamier?

Yes! To amp up the creaminess, stir in a splash of heavy cream or a few tablespoons of mascarpone cheese right before serving. It will make the Italian Penicillin Soup even more indulgent without losing its signature comforting charm.
