This Italian Penicillin Soup, packed with tender chicken, toothsome pasta, and a flavorful broth enhanced by a touch of lemon, has become a staple in my kitchen.
Why This Italian Penicillin Soup Works
This soup earns its “penicillin” moniker not from actual medication, but from its remarkably soothing qualities when you’re feeling under the weather.
Ingredients
- 2 tablespoons olive oil
- 1 medium yellow onion, finely chopped
- 2 medium carrots, peeled and finely chopped
- 2 celery stalks, finely chopped
- 4 cloves garlic, minced
- 1 teaspoon grated fresh ginger
- 1 pound boneless, skinless chicken thighs or breasts, cut into bite-sized pieces
- 8 cups low-sodium chicken broth
- 1 cup water
- 1 teaspoon dried oregano
- 1/2 teaspoon dried thyme
- 1/4 teaspoon red pepper flakes (optional, for a touch of heat)
- Salt and freshly ground black pepper, to taste
- 1/2 cup small pasta, such as ditalini, orzo, or small shells
- Juice of 1/2 to 1 lemon (to taste)
- 1/4 cup fresh parsley, chopped, for garnish
- Grated Parmesan cheese, for serving (optional)
Gathering these ingredients is the first step toward a restorative meal. Opt for fresh vegetables whenever possible; they contribute so much more flavor and vibrancy to a soup.
How to Make It
- Heat the olive oil in a large pot or Dutch oven over medium heat. Add the chopped onion, carrots, and celery.
- Add the minced garlic and grated ginger to the pot.
- Add the chicken pieces to the pot and season them with a pinch of salt and pepper.
- Pour in the chicken broth and water. Add the dried oregano, thyme, and red pepper flakes (if using).
- Stir in the small pasta. Increase the heat to medium and cook according to the pasta package directions, usually 7-10 minutes, until the pasta is al dente.
- Once the pasta is cooked and the chicken is tender, stir in the lemon juice, starting with the juice of half a lemon.
- Adjust the seasoning with salt and freshly ground black pepper as needed.
- Ladle the soup into bowls, garnish with fresh chopped parsley and a sprinkle of grated Parmesan cheese, if using.
This soup comes together with straightforward steps, each contributing to a rich and comforting final dish.

Common Mistakes
- Overcooking the pasta: Pasta can become mushy if left in the soup for too long, especially after the heat is turned off.
- Not browning the chicken: While optional, browning the chicken before adding liquid adds a layer of flavor that plain boiled chicken won’t achieve.
- Skipping the aromatics: Onion, carrot, and celery (the mirepoix) are foundational to delicious soup.
- Using low-quality broth: The broth is the backbone of your soup. A watery, bland broth will result in a bland soup.
- Adding lemon too early: Adding lemon juice at the very end preserves its bright, fresh flavor and aroma. Cooking it for too long can make the lemon flavor less vibrant.
- Not tasting and adjusting seasoning: Salt, pepper, and lemon are crucial for balancing flavors. Always taste your soup before serving and adjust as needed.
- Forgetting the ginger: The fresh ginger is a signature element in this “penicillin” style soup. Its subtle warmth is vital to the comforting profile.
Avoiding these common pitfalls will ensure your soup reaches its full potential. Paying attention to the details, like the cooking time of the pasta and the quality of your broth, makes a significant difference.

Storage and Reheating
- Allow the soup to cool completely before storing.
- Transfer to an airtight container and refrigerate. It will keep well for 3-4 days.
- For longer storage, freeze portions in freezer-safe containers or bags. Ensure there’s a little headspace for expansion if using plastic bags. Frozen soup is best consumed within 2-3 months for optimal quality.
- When reheating on the stovetop, gently warm the soup over low to medium heat, stirring occasionally. Avoid boiling, which can overcook the pasta and chicken. You may need to add a splash more broth or water if the soup has become too thick.
- Microwave reheating is also an option. Place a portion in a microwave-safe bowl, cover with a microwave-safe lid or plastic wrap (vented), and heat in 1-minute intervals, stirring in between, until heated through.
Proper storage ensures you can enjoy this comforting soup even days after it’s made. Freezing is a great option for batch cooking, providing a quick and easy meal on those nights when cooking from scratch isn’t feasible.

Leftover Ideas
- Soup as a sauce base: Thicken the leftover soup slightly by simmering it uncovered, then toss with cooked pasta for a quick, flavorful pasta sauce.
- Chicken and pasta salad: Once cooled, drain off some of the broth and mix the chicken and pasta with chopped celery, red onion, a dollop of mayonnaise or Greek yogurt, and a squeeze of lemon juice for a hearty salad.
- Savory pancakes or fritters: Chop the chicken and pasta into smaller pieces. Mix them with a little flour, egg, and seasonings, and fry them like small pancakes or fritters.
- Frittata or Quiche filling: Dice the chicken and pasta and incorporate them into a frittata or quiche mixture before baking. This adds protein and a comforting element.
- Stuffed Bell Peppers: Mix the leftover chicken and pasta with some cooked rice, herbs, and a touch of tomato sauce. Stuff into halved bell peppers and bake until tender.
Don’t let those delicious leftovers go to waste! This soup is versatile and can be transformed into a variety of other satisfying meals, extending its comfort even further.
