How to Make Italian Penicillin Soup Recipe
Step 1: Sauté Your Aromatics
Start by heating olive oil in a large pot over medium heat until shimmering. Add the diced onion and let it cook until translucent and sweet, around 5 minutes. This step is crucial because the softened onion gives the soup its signature depth and starts building those irresistible flavors.
Step 2: Add Garlic for That Aroma
Next, stir in the minced garlic and cook for about one minute until fragrant but not browned, as burnt garlic can turn bitter and disrupt the soup’s delicate balance.
Step 3: Toss in the Carrots and Celery
Give the diced carrots and celery a good stir-in and let them soften for about 5 to 7 minutes. This adds texture and a slightly sweet undertone, making each bite complex and satisfying.
Step 4: Season with Herbs and Spice
Time to sprinkle in the dried oregano, basil, and red pepper flakes. Stir them in well and cook for another minute or two to coax their flavors out. These spices bring the unmistakable Italian character to the soup and a gentle kick from the red pepper flakes.
Step 5: Pour in the Broth and Tomatoes
Now pour the chicken or vegetable broth along with the canned diced tomatoes and their juices. Bring everything to a boil. This is where the soup begins to transform, melding all those layered flavors.
Step 6: Cook the Pasta Until Perfect
Once boiling, add the uncooked pasta and reduce the heat to medium-low to simmer. Stir occasionally for 8 to 10 minutes until the pasta reaches al dente—a tender bite with just a hint of chew.
Step 7: Add Chicken for Extra Heartiness
If you’re using cooked shredded chicken, stir it in now and let it warm through for a couple of minutes. It makes this Italian Penicillin Soup Recipe a fantastic meal for weeknights or when you need something filling and nourishing.
Step 8: Wilt the Greens and Season
Finally, add the chopped spinach or kale and cook until just wilted, about 2 minutes. Season generously with salt and black pepper to taste, making sure every sip sings with balanced seasoning.
Step 9: Serve Hot and Beautifully Garnished
Ladle the soup into bowls and grate a generous amount of Parmesan cheese on top, finishing with a sprinkle of fresh parsley. It’s ready to warm you up and impress everyone at your table.
How to Serve Italian Penicillin Soup Recipe

Garnishes
Grated Parmesan and chopped parsley are simple yet classic toppings that add instant flavor and freshness. A drizzle of extra virgin olive oil or a squeeze of lemon juice can elevate it even further if you like a bright finish.
Side Dishes
This soup pairs beautifully with crusty Italian bread or garlic breadsticks to soak up every last drop. A crisp green salad or roasted vegetables also complement the warm, comforting vibes of the soup.
Creative Ways to Present
For a fun twist, serve the soup inside hollowed-out mini bread bowls or top it with a dollop of pesto for a burst of herbal richness. Adding a sprinkle of toasted pine nuts or chili oil can add an extra texture and flavor dimension that surprises the palate delightfully.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftover Italian Penicillin Soup Recipe into airtight containers and store in the refrigerator for up to 3 days. The flavors actually deepen after resting, making the next day’s meal even more satisfying.
Freezing
This soup freezes well for up to 3 months. It’s best to freeze it without the Parmesan cheese, which you can add fresh after reheating. When ready, thaw overnight in the fridge for best results.
Reheating
Reheat gently on the stove over low heat, stirring occasionally until warmed through. If the soup thickens too much, just add a splash of broth or water to bring it back to the perfect consistency.
FAQs
Can I make this soup vegetarian?
Absolutely! Simply use vegetable broth and omit the chicken. The combination of herbs, vegetables, and pasta creates wonderful flavor even without meat.
What type of pasta works best?
Small shapes like ditalini, small shells, or even elbow macaroni are ideal because they cook quickly and fit perfectly on a spoon with the other ingredients.
How spicy is this soup?
The red pepper flakes add a mild kick, but you can easily adjust the amount to make it milder or spicier depending on your preference.
Can I use fresh herbs instead of dried?
Yes, but use about three times the amount of fresh herbs as dried since fresh herbs are less concentrated in flavor.
Is this soup good for meal prep?
Definitely! It stores and reheats well, making it a fantastic option for preparing ahead and enjoying nourishing meals throughout the week.
