This hearty Italian Penicillin Soup has been my family's healing tradition for generations, combining the nourishing power of Italian cooking with the comfort concept of chicken soup for the soul. The rich broth infused with aromatic herbs and tender vegetables creates a bowl of pure comfort that truly feeds both body and spirit.
I first made this soup during a particularly brutal winter when my entire household was battling colds. The therapeutic process of chopping vegetables and inhaling the aromatic steam from the simmering broth began the healing before we even took our first spoonful.

Step-by-Step Instructions
- Build the Aromatic Base
- Heat olive oil in a large heavy bottomed pot over medium heat until shimmering but not smoking. Add the diced onion carrots and celery cooking for about 5 to 7 minutes until the vegetables begin to soften. Watch for the onions to become translucent but not brown as this indicates they have released their essential flavors. Add the minced garlic and cook for just one minute until you can smell its fragrance wafting up from the pot. This aromatic foundation sets the stage for everything that follows.
- Add Broth and Chicken
- Pour in the chicken broth slowly and nestle the chicken breast into the vegetables. The chicken should be partially submerged to ensure even cooking. Add bay leaves oregano thyme and red pepper flakes if using. Bring everything to a gentle boil before reducing to a steady simmer. This careful temperature control ensures the chicken remains tender while fully infusing the broth with its flavor.
- Simmer Until Tender
- Cover the pot partially allowing some steam to escape while retaining most of the heat. Let everything simmer gently for 25 to 30 minutes while occasionally checking the chicken. You will know it is done when the meat easily pulls away from the bone. The vegetables should be fork tender but still hold their shape. Your kitchen should now be filled with an incredible aroma that instantly soothes.
- Shred and Season
- Remove the chicken carefully to a cutting board and let it cool just enough to handle. Remove and discard the skin and bones then use two forks to pull the meat into bite sized shreds. Season the broth gradually with salt and pepper remembering that flavors intensify as the soup continues to cook and especially after refrigeration.
- Cook the Pasta
- Return the shredded chicken to the pot and bring the soup back to a gentle boil. Add the pasta and cook according to package directions until just tender. The pasta will release some starch that naturally thickens the broth slightly giving it that perfect consistency that clings to your spoon. Be careful not to overcook as the pasta will continue softening if left in the hot broth.
- Finish with Fresh Elements
- Remove the bay leaves as they have done their flavor work. Stir in the fresh lemon juice and chopped parsley which transforms the soup with brightness and color. These final touches balance the rich savory flavors and add a fresh dimension that makes the soup truly special. Taste once more and adjust seasonings if needed.

My absolute favorite part of this recipe is how the kitchen fills with aromas that instantly transport me back to my grandmothers tiny Italian kitchen. She would always say that the secret healing ingredient was the love that went into the chopping stirring and patient simmering. I find myself telling my own children the same thing now whenever they request this soup when feeling under the weather.
Storage and Reheating
This soup actually improves with time as the flavors meld together in the refrigerator. Store in airtight containers for up to 4 days for the best quality. The pasta will continue to absorb broth during storage so you may need to add a splash of additional broth or water when reheating. Warm gently on the stovetop rather than using high heat which can make the chicken tough. If freezing portion into individual containers without the pasta which can be added fresh when reheating.
Dietary Adaptations
This versatile soup accommodates many dietary needs with simple adjustments. For gluten free diets substitute the regular pasta with rice quinoa or gluten free pasta varieties. Vegetarians can omit the chicken and use vegetable broth adding cannellini or navy beans for protein and substance. Those following dairy free diets can skip the Parmesan cheese or substitute nutritional yeast for a similar umami quality. The soup remains delicious and nourishing with any of these modifications.
Serving Suggestions
Serve this healing soup in warmed bowls with a generous drizzle of extra virgin olive oil and freshly grated Parmigiano Reggiano on top. The heat from the soup will release the cheese's aroma while the olive oil adds richness and mouthfeel. Accompany with slices of crusty Italian bread for dipping into the flavorful broth. For a complete meal add a simple side salad dressed with lemon juice and olive oil to echo the bright flavors in the soup.

Throughout history Italian mothers and grandmothers have prepared similar restorative broths to nurture their families through illness and hardship. The combination of slow simmered broth protein rich chicken vitamin packed vegetables and aromatic herbs creates not just a delicious meal but a genuine remedy that comforts both physically and emotionally. The steam helps clear congestion while the warm broth soothes sore throats making this truly a culinary cure all.
