Ingredients

Chicken & Broth Base:
- 2 tablespoons olive oil
- 2 cloves garlic, finely minced
- 1-inch fresh ginger, peeled and grated
- 2 leeks, sliced thin (white and light green parts)
- 4 cups chicken broth (preferably homemade or low-sodium)
- 1 Parmesan rind
- 2 cups cooked shredded chicken (preferably smoked or roasted)
Vegetables & Aromatics:
- 2 carrots, diced
- 2 celery stalks, diced
- 1 small onion, finely chopped
- 1 teaspoon fresh thyme leaves
- 1 teaspoon fresh rosemary, chopped
- 1 bay leaf
Finishing & Garnish:
- 1 tablespoon fresh lemon juice
- Salt and freshly ground black pepper, to taste
- Fresh parsley, chopped, for garnish
- Optional: grated Parmesan for serving

Instructions

Prepare aromatics: Heat olive oil in a large soup pot over medium heat. Add garlic, ginger, and onions, sautéing for 2–3 minutes until fragrant.
Add vegetables: Stir in carrots, celery, and leeks. Cook for another 4–5 minutes until slightly softened.
Build the broth: Pour in chicken broth and add the Parmesan rind, thyme, rosemary, and bay leaf. Bring to a gentle boil, then reduce heat and simmer for 20 minutes to allow flavors to meld.
Add chicken: Stir in the shredded chicken and simmer for an additional 10 minutes, ensuring the chicken is warmed through and infused with the broth’s flavor.
Season & balance: Remove the Parmesan rind and bay leaf. Add fresh lemon juice, then taste and adjust seasoning with salt and pepper as desired.
Serve: Ladle soup into bowls, garnish with fresh parsley and a drizzle of olive oil. Serve immediately with crusty bread or a simple green salad for a complete meal.

Tips for the Perfect Italian Penicillin Soup

Use quality broth: Homemade chicken broth intensifies flavor, but store-bought low-sodium broth works in a pinch.
Fresh herbs matter: Thyme and rosemary provide aromatic depth; avoid dried herbs for the best taste.
Adjust ginger to taste: Start with 1 inch of fresh ginger; add more for extra warmth and immune-boosting properties.
Smoked chicken optional: Smoked chicken adds a subtle depth, but plain roasted chicken works equally well.

Variations

Vegetarian option: Replace chicken and chicken broth with vegetable broth and roasted tofu for a plant-based version.
Spicy kick: Add a pinch of red pepper flakes or a thin slice of fresh chili while sautéing aromatics for a warming, spicy twist.
Creamy version: Stir in ½ cup of coconut milk or cream at the end for a velvety texture without overpowering the flavors.

Serving Suggestions

Pair with warm, rustic Italian bread for dipping.
Serve with a wedge of lemon to brighten the flavors.
Top with a sprinkle of Parmesan or Pecorino Romano for added richness.

Fun Facts & Cultural Context

Despite its modern nickname, “Italian Penicillin Soup” is not an official Italian dish. It draws inspiration from traditional Italian chicken soups, incorporating herbs, garlic, and Parmesan rinds that naturally promote wellness.
The combination of garlic and ginger has been celebrated for centuries for its immune-boosting properties, making this soup a favorite during cold and flu season.
Parmesan rind is often used in Italian kitchens to add umami depth to soups and sauces without extra calories.

Why This Soup Works
