What is Italian Penicillin Soup?

Italian Penicillin Soup is basically the Mediterranean cousin of chicken noodle soup, but with a flavorful Italian twist. Think slow-simmered chicken (or shortcut rotisserie if you’re running on fumes), aromatic garlic, sautéed veggies, and pasta that makes every spoonful a little cozier. It’s garnished with fresh parsley and a generous sprinkle of Parmesan, which melts just enough to add that creamy comfort without overdoing it. The lemon juice at the end? That’s the mic drop—it brightens everything up and gives the soup a healing edge, hence the nickname “penicillin.” This soup has been dubbed a “cure-all” in many Italian households, and for good reason.

Reasons to Try Italian Penicillin Soup

If “comfort in a bowl” had a flavor, it’d be Italian Penicillin Soup. First off, it’s incredibly easy to make—like weeknight dinner easy. You don’t need any fancy gadgets or hard-to-pronounce ingredients. Just a big pot, some honest vegetables, chicken, and the kind of love that only Parmesan and lemon juice can deliver. Second, it’s a nutritional powerhouse. Chicken brings the protein, veggies add fiber and vitamins, and the broth keeps you hydrated—especially handy during cold and flu season. And let’s not forget its versatility: use thighs or breasts, sub in rotisserie chicken, or swap orzo for ditalini—whatever floats your spoon. Plus, this soup is a crowd-pleaser.

Step-by-Step Guide to Making Italian Penicillin Soup

Ready to make the coziest bowl of soup that’ll warm you up from the inside out? This step-by-step guide will walk you through the entire process of making Italian Penicillin Soup—from sautéing the veggies to finishing with that zesty lemon-Parmesan flair. Each step is simple, clear, and tailored for home cooks of all levels. Whether you’re new to the kitchen or a seasoned soup whisperer, you’ve got this!

Step 1: Sauté the Aromatics

Heat 2 tablespoons of olive oil in a large soup pot or Dutch oven over medium heat. Once it’s warm (you’ll know it’s ready when it shimmers slightly), toss in 1 chopped onion, 3 minced garlic cloves, 2 sliced carrots, and 2 chopped celery stalks.

Let this colorful veggie medley cook for about 5–6 minutes, stirring occasionally. You want everything to soften and become fragrant—think cozy kitchen vibes. This is where the soup starts to build its flavor base. Don’t rush this step—it’s your aromatic foundation!

Step 2: Add the Chicken and Seasonings

Once your veggies are soft and lightly golden, gently add 1 pound of boneless skinless chicken thighs or breasts directly into the pot. Pour in 6 cups of chicken broth, and then sprinkle in 1 teaspoon of dried oregano, 1 teaspoon of dried basil, and ½ teaspoon of red pepper flakes (totally optional if you like a little kick).

Bring the mixture to a gentle boil, then reduce the heat and let it simmer uncovered for 20–25 minutes. This simmering time allows the chicken to cook through and soak up all those comforting Italian flavors.

Want a shortcut? If you’re using cooked chicken, like leftovers or rotisserie, skip to Step 4 and reduce simmer time to about 10 minutes. For more soup shortcuts, check out this Creamy Marry Me Chicken Soup—it’s a reader favorite and just as easy.

Step 3: Shred the Chicken

Once the chicken is fully cooked and tender, carefully remove it from the pot with tongs or a slotted spoon. Transfer it to a cutting board and shred it using two forks. You can also use your hands once it cools slightly (less fancy, but faster).

Shredded chicken is the soul of this step-by-step recipe—it gives every bite of soup that satisfying texture and heartiness.

Return the shredded chicken back to the pot and give everything a good stir.

Step 4: Add the Pasta

Now it’s time for the pasta magic! Stir in 1 cup of small pasta—ditalini and orzo are both great choices. Cook for 8–10 minutes, or until the pasta is just al dente.

Keep an eye on it during this step, as pasta cooks quickly and can get mushy if overdone. If you’re meal-prepping, consider cooking the pasta separately and adding it when serving to avoid sogginess in leftovers.

Step 5: Brighten with Lemon and Parmesan

Once the pasta is cooked, stir in 2 tablespoons of fresh lemon juice and ¼ cup of grated Parmesan cheese. These two ingredients are small but mighty—they bring brightness and savory depth to the broth, making the soup feel like it came straight out of a cozy Italian kitchen.

Give the soup a taste and season with salt and pepper to your liking. This is the perfect time to adjust flavor before serving.

If you’ve got a Parmesan rind lying around, throw it into the soup during the simmering step for bonus flavor. You’ll thank yourself later.

Step 6: Garnish and Serve

Time to ladle that beautiful Italian Penicillin Soup into bowls! Top with chopped fresh parsley and an extra sprinkle of Parmesan for a final touch of flair.

What to Serve with Italian Penicillin Soup

This soup is already a complete meal, but let’s be honest—no bowl of brothy goodness is complete without a trusty sidekick. A big hunk of crusty bread or homemade garlic toast is practically non-negotiable. If you’re looking to bulk it up for dinner, pair it with a hearty side like this Creamy Winter Vegetable Casserole.

Key Tips for Making Italian Penicillin Soup

Here’s the scoop: for maximum flavor, sauté your veggies until they’re just starting to caramelize—don’t rush this step. If you’ve got the time, simmer the soup a bit longer before adding the pasta. It gives the broth more depth. Using rotisserie chicken? Great—just reduce simmering time since the chicken’s already cooked. Prefer a low-carb version? Swap pasta for cauliflower rice or skip it altogether and bulk it up with kale or spinach. Leftover Parmesan rinds? Toss one into the pot while simmering for an umami bomb. And last but not least—don’t skip the lemon juice. It may seem like a small thing, but it really makes the soup taste “alive.”

Storage and Reheating Tips for Italian Penicillin Soup

Leftovers? Lucky you. Italian Penicillin Soup stores like a champ. Let it cool completely, then stash it in an airtight container in the fridge for up to 4 days. If you’re planning to make a big batch for freezing, cook the pasta separately and add it fresh when serving—it tends to soak up all the broth and get mushy over time. For the freezer route, divide the soup (sans pasta) into freezer bags or containers and freeze for up to 3 months. Reheat on the stovetop over medium heat until warmed through. If it’s thickened up a bit, just add a splash of broth or water to loosen it.

FAQs

Can I use pre-cooked chicken?
Totally. Rotisserie chicken works great. Just add it after the veggies are sautéed and simmer for 10 minutes.

Can I make this in the slow cooker?
You sure can. Sauté the veggies first, then toss everything (except the pasta, lemon juice, and cheese) into your slow cooker. Cook on low 6–7 hours or high for 3–4. Add pasta during the last 30 minutes.

What pasta works best?
Ditalini and orzo are ideal, but really any small pasta will work. Even broken spaghetti in a pinch.

Is it spicy?
Only if you add the red pepper flakes. You’re the boss of the broth, so skip or scale as needed.

Can I make it vegetarian?
Absolutely. Swap the chicken for white beans or chickpeas and use veggie broth.
