How to Make Italian Penicillin Soup

Follow these simple steps for a perfect pot of soup every time. We’ve broken it down so you can build layers of flavor with confidence.

Step 1: Sauté the Aromatics

In a large pot or Dutch oven, heat the olive oil over medium heat. Add the onion, carrots, and celery and cook, stirring occasionally, until softened, about 8 minutes. Stir in the garlic and cook until fragrant, about 1 minute.

Step 2: Simmer the Broth and Chicken

Pour in the chicken broth and add the chicken thighs, oregano, thyme, and bay leaf. Season lightly with salt and pepper. Bring to a boil, then reduce heat to maintain a gentle simmer. Cover and cook until the chicken is very tender and easily shredded, about 25 minutes.

Step 3: Cook the Pasta

Remove the chicken thighs to a plate using tongs and set aside to cool slightly. Add the ditalini pasta to the simmering broth and cook according to package directions until al dente, usually 8-10 minutes.

Step 4: Shred the Chicken

While the pasta cooks, use two forks to shred the chicken into bite-sized pieces, discarding any excess fat.

Step 5: Combine and Brighten

Once the pasta is cooked, return the shredded chicken to the pot. Stir in the fresh lemon juice and taste the soup, adjusting seasoning with more salt and pepper as needed.

Step 6: Finish and Serve

Remove the pot from the heat and discard the bay leaf. Stir in the fresh parsley just before serving. Ladle the soup into bowls while hot.

Pro Tips & Tasty Tweaks

After making this Italian Penicillin Soup countless times, our team has gathered a few favorite insights to help you make it your own.
  • Flavor Swap: For a different herbal note, swap the thyme for a pinch of rosemary or marjoram.
  • Timing Adjustment: If you’re prepping ahead, cook the pasta separately and add it to individual bowls when serving to prevent it from getting mushy in the stored soup.
  • Prep Fix: To save time, use a pre-chopped mirepoix blend from the produce section for the onion, carrot, and celery.
  • Storage Tip: This soup stores beautifully. Let it cool completely, then refrigerate in an airtight container for up to 4 days. The flavors meld and deepen, making leftovers even better.

Flavor & Texture Notes

When you make this Italian Penicillin Soup, here’s what to expect. First, the aroma as it simmers is incredible—savory, herbal, and deeply comforting. The final bowl should have a rich, golden broth that’s deeply flavorful but not heavy. The chicken thighs should be fall-apart tender, and the ditalini pasta provides a delightful, soft bite in every spoonful. The magic finish comes from the fresh lemon juice and parsley stirred in at the end. They don’t make the soup taste lemony, but rather, they lift all the other flavors and add a essential layer of freshness that defines this healing chicken soup. You’ll know it’s perfectly seasoned when the broth tastes savory and balanced, inviting you back for another spoonful.

Variations & Substitutions

One of the best things about this Italian Penicillin Soup is how adaptable it is. Here are a few ways our team likes to mix it up, depending on what we have on hand or what we’re craving. For a heartier twist, stir in a couple handfuls of fresh spinach or chopped kale during the last few minutes of cooking. If you love a creamy chicken noodle soup, you can stir in a 1/4 cup of grated Parmesan cheese right at the end for a subtle, savory richness. Don’t have ditalini? Any small pasta like orzo, small shells, or even broken angel hair works perfectly. Finally, for a different protein, shredded rotisserie chicken is a fantastic shortcut—just add it when you return the shredded chicken to the pot to warm through.

Make-Ahead & Scaling

We love a recipe that works with your schedule, and this Italian Penicillin Soup is wonderfully flexible. Whether you’re meal prepping for the week or doubling the batch for a crowd, we’ve got you covered with our team’s favorite strategies. For make-ahead ease, you can chop the onion, carrots, and celery a day or two in advance and store them in an airtight container in the fridge. You can also cook the entire soup, but for the best texture, we recommend holding off on adding the pasta until you reheat. Simply store the finished broth and shredded chicken separately, then cook the ditalini fresh when you’re ready to serve. This keeps your healing chicken soup from becoming starchy or mushy. Scaling this recipe is straightforward. To halve it, simply divide all ingredients by two and use a medium saucepan. To double it for a big family dinner or to freeze, use your largest stockpot. The simmering time for the chicken remains the same, but it may take a few extra minutes for the larger volume of broth to come to a gentle boil initially. This Tuscan chicken soup is a true crowd-pleaser that scales beautifully.

How to Serve Italian Penicillin Soup

Part of the joy of this Italian Penicillin Soup is how you present it. We always say a great bowl of soup is a meal, but the right accompaniments turn it into an experience. Here’s how we love to serve it. During our team tests, we found that a simple, crusty loaf of bread is non-negotiable. It’s perfect for sopping up every last drop of that savory broth. For a light and fresh side, a simple green salad with a bright vinaigrette balances the richness of the soup perfectly. If you’re leaning into the Italian chicken soup vibe, a sprinkle of grated Parmesan and a crack of black pepper right at the table lets everyone customize their bowl. We love that this soup feels special enough for company but easy enough for a quiet Tuesday. Ladle it into deep, wide bowls to showcase all the tender chicken, pasta, and vegetables. It’s the ultimate chicken noodle soup, reimagined with Italian soul.

Mistakes to Avoid

We’ve made this soup enough times to learn from our own missteps, so you don’t have to. Avoiding these common pitfalls will ensure your Italian Penicillin Soup turns out perfectly every single time. First, don’t rush the sauté. If you don’t cook the onion, carrot, and celery until truly softened, you miss out on the sweet, foundational flavor they build for the whole pot. Second, avoid a rolling boil when simmering the chicken. A gentle simmer is key to tender, shreddable meat and a clear, flavorful broth. A hard boil can make the chicken tough. Another common question we get is about pasta texture. To prevent a mushy healing chicken soup, don’t overcook the ditalini in the broth. Remember, it will continue to soften a bit as it sits in the hot soup. Cook it just to al dente. Finally, don’t skip the lemon juice and parsley at the end. They’re not just garnishes; they’re essential ingredients that brighten and balance the entire dish. If your soup tastes a little flat, a squeeze of fresh lemon is often the fix. By keeping these tips in mind, you’ll master this comforting Tuscan chicken soup on your very first try.

How to Store Italian Penicillin Soup

Good news: this soup tastes even better the next day as the flavors have more time to meld. We always make a little extra on purpose. Here’s our team-tested method for storing and reheating your Italian Penicillin Soup. Let the soup cool completely at room temperature before transferring it to storage. We prefer using glass containers with tight-fitting lids. For the best results, store the soup with the pasta already in it for no more than 3-4 days in the refrigerator. If you plan to keep it longer, store the broth and chicken separately and cook fresh pasta when reheating. To freeze, portion the cooled soup (without pasta for best texture) into freezer-safe bags or containers, leaving about an inch of space for expansion. It will keep well for up to 3 months. Thaw overnight in the refrigerator. When reheating, warm it gently on the stovetop over medium-low heat until steaming hot. If the broth has thickened in the fridge, just add a splash of water or extra broth when reheating to reach your perfect consistency.

Frequently Asked Questions

Can I use chicken breasts instead of thighs?

You absolutely can, but we recommend boneless, skinless chicken thighs for their richer flavor and more forgiving texture. Breasts can dry out if simmered too long. If using breasts, reduce the simmering time to about 15-20 minutes, or just until cooked through.

How do I keep the pasta from getting soggy in leftovers?

The best trick is to store the soup and cooked pasta separately. When you’re ready for leftovers, reheat the broth and chicken, then add the pasta to warm through. If the pasta is already in the soup, it will soften further but will still be delicious.

What can I use if I don’t have ditalini pasta?

Any small pasta works wonderfully. Our favorite swaps are orzo, small shells (pastina), or even broken pieces of spaghetti or fettuccine. The goal is a small, spoon-friendly shape that complements the broth and chicken.

Can I make this soup in a slow cooker?

Yes, it adapts beautifully. Sauté the vegetables on the stovetop first for the best flavor, then transfer everything except the pasta, lemon, and parsley to the slow cooker. Cook on low for 6-7 hours or high for 3-4 hours. Shred the chicken, then add cooked pasta and the fresh finishes just before serving.

Conclusion

At its heart, this Italian Penicillin Soup is about more than just following a recipe—it’s about creating a moment of warmth and comfort. We love how this simple pot of soup can turn an ordinary day into something a little cozier and a lot more delicious. Remember, the magic is in the slow simmer and the fresh, bright finish. Whether you’re cooking for your family or just for yourself, this soup is a heartfelt way to show you care. We hope you enjoy making it, sharing it, and savoring every spoonful as much as we do.
