how to make Italian Penicillin Soup
Ingredients
- 2 tablespoons extra virgin olive oil
- 1 large onion, diced (about 1 cup)
- 3 medium carrots, sliced into rounds
- 3 celery stalks, chopped
- 4 garlic cloves, minced
- 8 cups low-sodium chicken broth (or vegetable broth for vegetarian option)
- 1 whole chicken breast, bone-in and skin-on (about 1 pound)
- 2 bay leaves
- 1 cup small pasta (ditalini, orzo, or small shells)
- 1 teaspoon dried oregano
- 1/2 teaspoon dried thyme
- 1/4 teaspoon red pepper flakes (optional)
- Salt and freshly ground black pepper to taste
- 2 tablespoons fresh lemon juice
- 1/4 cup fresh parsley, chopped
Garnishes & finishing touches:
- Freshly grated Parmigiano-Reggiano cheese
- Extra virgin olive oil for drizzling
- Crusty Italian bread for serving
Substitution notes: For gluten-free diets, replace pasta with rice or omit entirely. Vegetarians can skip the chicken and use vegetable broth, adding white beans for protein. Those avoiding dairy can skip the cheese garnish or use nutritional yeast instead.
Directions
Build the Aromatic Base: Heat olive oil in a large pot over medium heat. Add the diced onion, carrots, and celery. Cook for about 5-7 minutes until the vegetables soften, and the onion turns translucent. Stir in the minced garlic and cook for another minute until fragrant.
Add Broth and Chicken: Pour in the chicken broth and nestle the chicken breast into the pot. Add bay leaves, oregano, thyme, and red pepper flakes if using. Bring to a gentle boil, then reduce heat to maintain a steady simmer.
Simmer Until Tender: Cover partially and simmer for 25-30 minutes, or until the chicken is cooked through and can be shredded easily. Remove the chicken breast and allow it to cool slightly.
Shred and Season: Remove the skin and bones from the chicken. Shred the meat into bite-sized pieces and return it to the pot. Season the broth with salt and pepper to taste.
Cook the Pasta: Bring the soup back to a gentle boil. Add the pasta and cook according to package directions until al dente. The starch in the pasta will slightly thicken the broth.
Finish with Fresh Elements: Remove the bay leaves from the soup. Stir in fresh lemon juice and chopped parsley. Taste and adjust seasoning. Serve the soup with grated Parmigiano-Reggiano, a drizzle of extra virgin olive oil, and crusty Italian bread.
