How to Make Italian Penicillin Soup

1. Sauté the Aromatics

In a large soup pot, heat the olive oil over medium heat. Add diced onion, carrots, and celery. Cook for 5–7 minutes, stirring occasionally, until the vegetables begin to soften and the onion is translucent. Add garlic and cook for another minute, stirring to release the fragrance without browning it.

2. Simmer the Chicken

Pour in the broth and nestle in the chicken breast. Add bay leaves, oregano, thyme, and red pepper flakes if using. Bring to a gentle boil, then immediately reduce the heat to a low simmer. Partially cover the pot and let the chicken cook for 25–30 minutes, until it’s fully cooked and tender.

3. Shred the Chicken

Carefully remove the chicken from the pot and let it cool slightly. Shred the meat using two forks, discarding the skin and bones. While the chicken is resting, taste the broth and adjust salt or seasoning if needed.

4. Cook the Pasta

Return the shredded chicken to the pot. Bring the soup back to a gentle boil and stir in the pasta. Cook until al dente, according to the pasta’s package directions, usually 8–10 minutes. Stir occasionally so the pasta doesn’t stick.

5. Finish and Serve

Once the pasta is done, remove the bay leaves. Stir in fresh lemon juice and chopped parsley. Taste one more time and adjust seasoning if needed. Ladle the soup into bowls and garnish with freshly grated Parmigiano-Reggiano, a drizzle of olive oil, and crusty bread on the side.

Italian Penicillin Soup Variations and Dietary Swaps

This soup is wonderfully flexible. Here’s how you can make it work for different diets or preferences:

Vegetarian? Use vegetable broth and swap the chicken for canned white beans or chickpeas. Add them with the pasta so they soak up the flavor.
Gluten-Free? Replace the pasta with cooked rice, quinoa, or gluten-free pasta. Add these just before serving to prevent overcooking.
Dairy-Free? Simply skip the cheese or replace it with nutritional yeast for a similar umami kick.
Low-Sodium? Choose unsalted broth and season gradually to control the salt content.
Extra Veggies? Toss in baby spinach or chopped kale at the end of cooking for a nutrient boost.

Tips for Perfect Italian Penicillin Soup

Simmer Gently: A rolling boil will toughen the chicken, a soft simmer creates a rich, clear broth.
Add Pasta Last: To avoid soggy noodles, always cook the pasta just before serving or separately if meal prepping.
Freeze Smart: If freezing, do so before adding the pasta. Reheat and stir in freshly cooked pasta for best texture.
Garnish Wisely: Fresh lemon juice, parsley, and a good olive oil make this soup feel bright and balanced.
Make it a Meal: Pair with a salad and toasted bread for a complete comforting dinner.
