How to Make Italian Penicillin Soup Recipe
Step 1: Sauté the Aromatics
Heat the olive oil gently over medium heat and add the diced yellow onion. Cooking the onion until it softens releases its sweet, mellow flavors, laying the foundation for this soul-warming soup. Once translucent, add the minced garlic, sliced carrots, and celery, letting these fragrant veggies mingle and soften for a few minutes, building layers of flavor right in your pot.
Step 2: Season and Simmer
Now it’s time to add the dried oregano, red pepper flakes (if you like a touch of spice), salt, and black pepper. Stir everything to coat those softened veggies in herbs and spices, awakening their aromas. Pour in the chicken broth and bring the pot to a lively boil, signaling that hearty Italian taste is on its way!
Step 3: Add Tomatoes and Pasta
To the bubbling broth, add the diced tomatoes with their juices and small pasta like ditalini or orzo. Reducing the heat to a gentle simmer, cook the mixture until the pasta is just tender with a little bite left. This step ensures the pasta absorbs the rich flavors soaking through the broth.
Step 4: Stir in Chicken and Spinach
Fold in the shredded cooked chicken and chopped fresh spinach, letting them cook together just until the spinach wilts and the chicken is warmed through. This keeps the chicken juicy and the spinach fresh, adding a delightful complexity of textures.
Step 5: Finish with Lemon and Parsley
Just before serving, stir in the fresh lemon juice and chopped parsley. This final flourish brightens the soup, giving every spoonful a refreshing lift that perfectly complements the heartiness beneath. Serve piping hot, with a generous sprinkle of grated Parmesan if you like, and prepare for a comforting, nourishing meal.

Garnishes
While the grated Parmesan is a classic and savory topping that adds a lovely salty, nutty contrast, fresh parsley sprinkled on top offers a bright, fresh aroma. For an added touch, a drizzle of high-quality extra virgin olive oil or a few cracks of black pepper can elevate the presentation and flavor even further.
Side Dishes
This soup shines beautifully alongside a crusty Italian bread or garlic bread to soak up every last drop of that aromatic broth. A simple side salad with lemon vinaigrette or roasted vegetables can round out your meal, balancing the warm, comforting qualities of the soup with fresh, crisp elements.

For a fun twist, add a sprinkle of chili oil or fresh basil leaves on top, giving each bowl a splash of color and a gourmet flair.
Make Ahead and Storage
Storing Leftovers
Let the soup cool to room temperature before transferring it to airtight containers. Stored in the refrigerator, it keeps wonderfully for 3 to 4 days, offering you delicious, ready-made comfort whenever you want.
Freezing
Italian Penicillin Soup Recipe freezes exceptionally well. Pour cooled soup into freezer-safe containers, leaving some space at the top for expansion. It will keep its flavor and texture for up to 3 months, making it a great option for meal prepping or busy nights.
Reheating
Reheat your soup gently on the stovetop over medium-low heat to maintain the tenderness of the chicken and the freshness of the spinach, stirring occasionally. If it seems thick, add a splash of broth or water to loosen it up. Microwaving in short increments with stirring between cycles also works beautifully for a quick fix.
