Ingredients

For the most flavorful Italian Penicillin Soup, choose fresh vegetables, good-quality chicken, and a flavorful broth.

• 8 cups chicken broth (1.9 L)
• 1 pound boneless, skinless chicken breasts (450 g)
• 1 teaspoon dried Italian seasoning (3 g)
• 1/2 teaspoon dried thyme (1 g)
• 1/2 teaspoon black pepper (1 g)
• 1/2 teaspoon salt, or to taste
• 1 cup small pasta such as ditalini (100 g)
• 2 cups baby spinach (60 g)

Use low-sodium broth if you want better control over the final salt level.

Pro Tips

The first secret to excellent Italian Penicillin Soup is building flavor before adding the broth. Sauté the onion, carrots, and celery in olive oil until they begin to soften. This simple step brings out their natural sweetness and creates a flavorful foundation.

Second, avoid boiling the chicken aggressively. A gentle simmer keeps chicken breasts tender instead of making them tough or dry. Once cooked through, remove the chicken, shred it with two forks, and return it to the pot.

Third, watch the pasta carefully. Small pasta cooks quickly and can absorb a surprising amount of broth. Add it toward the end of cooking and simmer just until tender. If you plan to save leftovers, consider cooking the pasta separately and adding it to individual bowls. This keeps it from becoming overly soft.

Finally, finish the soup with fresh lemon juice, parsley, and Parmesan. These ingredients brighten the broth and balance its savory richness.

Instructions

Step 1: Sauté the vegetables

Heat the olive oil in a large Dutch oven or soup pot over medium heat. Add the diced onion, carrots, and celery. Cook for 5 to 7 minutes, stirring occasionally, until the vegetables soften slightly and the onion turns translucent.

Add the minced garlic and cook for about 30 seconds. Keep the garlic moving so it becomes fragrant without browning too much.

Step 2: Build the broth

Pour in the chicken broth and stir well, scraping up any flavorful bits from the bottom of the pot. Add the Italian seasoning, thyme, black pepper, and salt.

Place the chicken breasts directly into the broth. Increase the heat and bring everything to a gentle boil.

Step 3: Simmer the chicken

Reduce the heat to medium-low once the broth starts bubbling. Cover the pot partially and simmer for approximately 15 to 20 minutes, depending on the thickness of the chicken.

Check that the chicken reaches 165°F (74°C) in the center. Remove the cooked chicken and place it on a plate. Let it rest for a few minutes.

Step 4: Cook the pasta

Bring the soup back to a gentle simmer. Add the small pasta and cook according to the package directions, usually 7 to 10 minutes.

Stir occasionally to prevent the pasta from sticking to the bottom. Keep the soup at a gentle simmer rather than a hard boil.

Step 5: Shred the chicken

While the pasta cooks, shred the chicken into bite-sized pieces using two forks. If you prefer larger pieces, cut the chicken with a knife instead.

Return the shredded chicken to the pot once the pasta reaches al dente texture.

Step 6: Add the finishing ingredients

Stir in the baby spinach and cook for 1 to 2 minutes, just until the leaves wilt. Add the Parmesan and fresh parsley, then stir gently.

Finish with fresh lemon juice. Taste the broth and adjust the salt and pepper if needed.

Step 7: Serve immediately

Ladle the hot soup into bowls and sprinkle each serving with extra Parmesan and parsley. Add freshly cracked black pepper for a little extra warmth.

For the ultimate comfort-food experience, serve your Italian Penicillin Soup with warm crusty bread and enjoy it while the broth is piping hot.

Variations

You can easily customize this soup while keeping its comforting Italian character. For a creamy version, stir in 1/2 cup (120 ml) of heavy cream near the end and reduce the Parmesan slightly.

For a lighter option, replace chicken breasts with shredded rotisserie chicken. Add the cooked chicken during the final few minutes so it stays juicy. You can also swap spinach for kale, Swiss chard, or escarole.

For a vegetarian variation, use vegetable broth and replace the chicken with white beans or chickpeas. Add extra vegetables such as zucchini or mushrooms for more substance.

Small pasta shapes work best, but orzo, broken spaghetti, acini di pepe, or even tortellini can create delicious variations. These changes turn this classic Italian Penicillin Soup into a flexible meal for different tastes and dietary needs.

Storage and Serving

Allow leftover Italian Penicillin Soup to cool slightly before transferring it to airtight containers. Refrigerate for up to 4 days. Reheat individual portions gently on the stovetop or in the microwave until steaming hot.

If the pasta absorbs too much broth overnight, add a splash of chicken broth or water while reheating. Stir well and adjust the seasoning before serving.

This soup pairs beautifully with toasted sourdough, garlic bread, or a simple green salad. For a more substantial meal, serve it alongside a warm Italian sandwich or roasted vegetables.

You can also freeze the soup for up to 3 months, although pasta may soften after thawing. For the best freezer results, prepare the soup without pasta and add freshly cooked pasta when reheating.
