How to Make Italian Penicillin Soup Recipe
Step 1: Sauté the Aromatics
Heat your olive oil in a large pot over medium heat. Once shimmering, add the diced onion, minced garlic, sliced carrots, and celery. Stir occasionally and cook for 5 to 7 minutes until these veggies soften and release their wonderful fragrances. This foundation layer is where your soup starts to develop its soulful character.
Step 2: Brown the Chicken
Next, toss in the diced chicken pieces. Let them cook for about 5 to 7 minutes, turning occasionally so they brown evenly on all sides. This step locks in juiciness and adds a subtle nuttiness to the soup that will shine through in every spoonful.
Step 3: Add Broth, Tomatoes, and Zucchini
Pour in the chicken broth along with the canned diced tomatoes and their juices, then stir in the diced zucchini and Italian seasoning. Bring the pot to a gentle simmer, and let it cook for 10 to 15 minutes. This is where the flavors meld beautifully, creating a fragrant, hearty base for the rest of the soup.
Step 4: Cook the Pasta
Add your choice of small pasta, such as ditalini or orzo, directly into the simmering soup. Follow the package directions for cooking time—generally 7 to 10 minutes—until the pasta is tender but still has a pleasant bite. This step thickens the soup slightly and makes it more satisfying.
Step 5: Stir in Spinach and Season
For a nutritional boost and pretty pops of green, toss in the baby spinach if you’re using it. Season the soup generously with salt and pepper, giving it a taste and adjusting as needed. Let it simmer for a couple more minutes until the spinach wilts gently into the broth.
Step 6: Serve and Garnish
Ladle the steaming soup into warm bowls and sprinkle with freshly chopped parsley. This finishing touch adds a burst of color and a fresh, herbal brightness that perfectly complements all the rich flavors you’ve built. Serve it up and enjoy every comforting bite!
How to Serve Italian Penicillin Soup Recipe

Garnishes
Fresh parsley is a classic and simple garnish that lifts the dish, but you can also add a drizzle of good-quality extra virgin olive oil or even a sprinkle of grated Parmesan cheese for an extra layer of flavor and richness. A few cracked black peppercorns on top can add a nice touch of spice and aroma.
Side Dishes
This soup pairs beautifully with crusty garlic bread or a warm baguette, perfect for dipping and soaking up every last drop of broth. A crisp green salad dressed in lemon vinaigrette also complements the richness of the soup and keeps the meal balanced and refreshing.
Creative Ways to Present
For a fun twist, serve the soup in hollowed-out sourdough bread bowls for a rustic, Instagram-worthy presentation. You can also pack it into colorful ceramic bowls or mugs for casual lunches or dinners. Adding a lemon wedge on the side for squeezing just before eating brightens the overall flavor beautifully.
Make Ahead and Storage
Storing Leftovers
This Italian Penicillin Soup Recipe keeps wonderfully in the fridge for up to 3 days. Store the soup in an airtight container to preserve its fresh flavors and warmth. Just give it a good stir before reheating to redistribute all those lovely ingredients evenly.
Freezing
You can absolutely freeze this soup for up to 2 months. Make sure it cools completely before transferring it to freezer-safe containers or heavy-duty zip-top bags. When you’re ready to enjoy it, thaw it overnight in the fridge for best texture and flavor retention.
Reheating
When reheating, warm the soup gently over medium-low heat to prevent the chicken from drying out and the pasta from becoming mushy. If the soup seems too thick, stir in a splash of chicken broth or water to loosen it back up to the perfect consistency.
FAQs
Can I use other types of pasta in the Italian Penicillin Soup Recipe?
Definitely! While small pastas like ditalini or orzo work best for texture and portion, you can swap these with small shells or elbow macaroni. Just adjust the cooking time accordingly to keep the pasta tender but not overcooked.
Is it possible to make this soup vegetarian?
Yes! Replace the chicken with hearty vegetables like mushrooms or add beans for protein. Use vegetable broth instead of chicken broth, and you’ll still have an incredibly flavorful and comforting soup.
Can I prepare this soup in a slow cooker?
Absolutely. After sautéing the aromatics and browning the chicken, transfer everything to a slow cooker and cook on low for 4-6 hours. Add the pasta during the last 30 minutes and stir in spinach just before serving.
How can I make the soup more filling?
Increasing the amount of pasta or adding beans like cannellini or chickpeas can boost the heartiness of the soup. You might also add more chicken or toss in a handful of cooked rice for extra substance.
What’s the best way to store leftovers with pasta?
Since pasta tends to soak up liquid over time, if you plan to keep leftovers, consider storing the soup and pasta separately if possible. Otherwise, add a little extra broth or water when reheating to keep the soup from getting too thick or dry.
