Italian Penicillin Soup: 45-Minute Hug in a Bowl

In my Sicilian-American kitchen, the first sniffle of a cold meant one thing: Nonna was already pulling out the big pot for her famous Italian Penicillin Soup. Forget the over-the-counter stuff—this steaming bowl of tender chicken, tiny pasta, and herbs was our family’s actual cure-all. The aroma of rosemary and thyme would fill the house, and suddenly, being sick didn’t feel so bad.

It comes together so simply, with pantry staples and a whole lot of love. One spoonful and you’ll understand why we call it liquid gold—it warms you from the inside out, and honestly, it just makes everything feel a little bit better.

Ingredients for Italian Penicillin Soup

The magic of this Italian Penicillin Soup really comes down to keeping things simple but not skimping on quality. Fresh, bright veggies and good olive oil build a foundation that no powder from a packet can touch. I’m a stickler for dicing everything to a similar, small ¼-inch size so each spoonful gets the perfect mix of tender vegetables and chicken. Trust me, it makes a difference. Here’s exactly what you’ll need to grab from your fridge and pantry.

• 1 tablespoon olive oil (extra virgin preferred)
• 1 small yellow onion, finely chopped
• 2 medium carrots, peeled and ¼-inch diced
• 2 celery stalks, ¼-inch diced
• 3 cloves garlic, minced
• 8 cups low-sodium chicken broth
• 1 pound boneless, skinless chicken breasts (about 2 medium)
• 1 dried bay leaf
• 1 large sprig fresh rosemary (about 5 inches)
• 2 sprigs fresh thyme
• 1 cup pastina or other tiny pasta such as stelline
• salt and freshly ground black pepper to taste
• ¼ cup chopped fresh flat-leaf parsley for garnish
• freshly grated Parmesan cheese for serving

Ingredient Notes and Substitutions

Look, I get it—life happens, and you might be missing something. No stress. The soul of this Italian Penicillin Soup is its comforting, healing vibe, and it’s totally flexible. First, if you’re in a real rush, grab a rotisserie chicken. Just shred it up and toss it in with the pasta during the last few minutes of cooking. It’s a brilliant time-saver that still tastes homemade.

Don’t have the exact veggies? Swap a leek for the onion for a gentler, sweeter base. A parsnip can step in for a carrot, giving it an earthier twist, and a bulb of fennel instead of celery adds a subtle, cozy anise note. If your garden isn’t bursting with fresh herbs, no problem—just use ½ teaspoon of dried rosemary and ¼ teaspoon of dried thyme. As for the pasta, any tiny shape will work wonders. Orzo, ditalini, or even spaghetti broken into little bits all do the trick. And for my gluten-free friends, just use your favorite gluten-free small pasta, but keep an eye on it so it doesn’t get mushy.

Equipment You’ll Need

You really don’t need a gadget graveyard for this soup. Just a few trusty tools that I bet are already in your kitchen. Grab your favorite large Dutch oven or heavy-bottomed pot—the deeper, the better to keep all that golden broth from splashing. A solid cutting board, a sharp chef’s knife, and your measuring cups are a must. Oh, and don’t forget two forks for shredding that perfectly poached chicken in a flash.

How to Prepare Italian Penicillin Soup

Sauté the Vegetables

Heat the olive oil in your big pot over medium heat. Toss in the onion, carrots, and celery. Let them cook, stirring now and then, for about 5 minutes—just until they soften and smell amazing. Don’t let them brown; you’re building a gentle, sweet base here.

Build the Broth and Cook the Chicken

Pour in the chicken broth, then add the whole chicken breasts, bay leaf, rosemary, and thyme. Bring everything to a boil, then immediately drop the heat to a low simmer. Cover the pot and let it bubble gently for 20 minutes, or until the chicken is cooked through (165°F inside). This slow poaching keeps the meat beautifully tender.

Shred the Chicken and Add Pasta

Fish the chicken out onto a plate and let it cool enough to handle. Shred it with two forks—it’ll fall apart beautifully. Toss the chicken back into the pot, then stir in the pastina. Simmer for 8-10 minutes, stirring occasionally so it doesn’t stick, until the pasta is tender. Before serving, fish out the bay leaf and herb stems. No one wants a crunchy surprise!

Finish and Serve

Now for the final touches. Taste and season with salt and pepper until it’s perfect. Ladle the soup into bowls and let everyone top their own with fresh parsley and a generous shower of Parmesan. Remember, the pastina will keep absorbing broth, so add a splash extra when reheating leftovers.

Tips for the Best Italian Penicillin Soup

A few simple tricks turn this Italian Penicillin Soup from good to absolute magic. I season in layers—a pinch of salt goes in with the veggies, and I taste again before serving. If you have homemade broth, it’s a game-changer; the soup tastes like it’s been simmering all day. Shred the chicken while it’s still warm (so much easier!) so it stays juicy. Right before ladling, squeeze in a tiny hit of lemon juice—you won’t believe how it wakes up the whole pot. And watch that pastina like a hawk: the moment it’s al dente, pull the soup off the heat, because those little stars keep cooking and will turn to mush before you know it.

Italian Penicillin Soup Variations

This Italian Penicillin Soup is a canvas for whatever you’ve got on hand. I always toss a forgotten Parmesan rind into the broth while it simmers—it melts in the most incredible savory depth. For a pop of green, stir in a handful of baby spinach at the very end until it just wilts. Rotisserie chicken? Shred it and skip the poaching step entirely. If my kids are asking for something extra cozy, I swirl in a splash of heavy cream right before serving. And on busy weeks, a can of drained cannellini beans makes it a hearty, protein-packed meal that still feels like a hug.

How to Store and Reheat Italian Penicillin Soup

Let leftovers cool completely, then pop them into an airtight container in the fridge for up to three days. A little heads-up: the pastina is a total broth thief—it’ll soak up every drop overnight. Just splash in extra chicken broth when you reheat it on the stove or in the microwave until it’s nice and soupy again. For freezing, skip the pasta. Freeze the broth with the chicken and veggies for up to two months, then cook fresh pastina when you’re ready to serve. It’s the only way to keep that perfect texture.
