Parmesan rind (optional): Adds a subtle umami and creamy depth to the broth if you choose to use it.
Water (6 cups): The liquid base that carries all these flavors gently together.

How to Make Italian Penicillin Soup Recipe

Step 1: Sauté the Base Vegetables

Start by heating the olive oil in a large pot over medium-high heat. Add the diced yellow onion, carrots, and celery with a pinch of salt and pepper. Let these veggies soften and sweeten up over 6-8 minutes, stirring occasionally. Then toss in the minced garlic and sauté just until fragrant—this quick step lifts the whole flavor foundation before adding the liquids.

Step 2: Add the Broth and Chicken Carcass

Next, it’s time to build your broth. Drop the roast chicken carcass into the pot alongside the chicken broth, 6 cups of water, bay leaf, and the optional parmesan rind. This combo simmers together for the perfect rich, savory base that carries all the subtle flavors you want in this soup. Increasing the flavor complexity right here takes your homemade soup from simple to spectacular.

Step 3: Simmer and Skim

Bring everything to a boil, then reduce the heat to a gentle simmer. Let it bubble away for about 20 minutes, during which you’ll want to skim off any foam or fat rising to the surface with a ladle. This keeps your broth clear and clean tasting, while the slow cook extracts all the lovely depth from the chicken and aromatics.

Step 4: Strain and Reserve

After simmering, remove and discard the bay leaf and parmesan rind, if used. Carefully extract the chicken carcass with tongs, setting it aside to cool. Half of the softened veggies in the pot should be removed with a slotted spoon and saved for later, which will contribute wonderful texture to the finished soup.

Step 5: Puree the Broth

Use an immersion blender or transfer the broth and remaining veggies to a regular blender, then puree until delightfully smooth. This is where the soup earns its silky, comforting texture. The pureed veggies blend seamlessly with the broth, creating a luscious base for the pasta and chicken additions.

Step 6: Cook the Pasta

Return the pureed broth to the pot and bring it back to a boil. Stir in the acini di pepe pasta, reduce the heat again, and simmer for 10-12 minutes. Stir occasionally until the pasta is tender but still holds its shape, adding to the soup’s heartiness and delightful mouthfeel.

Step 7: Add Shredded Chicken and Reserved Veggies

While your pasta cooks, pull the cooled chicken meat from the carcass, shredding it into bite-sized pieces. When the pasta is just right, return the shredded chicken and reserved veggies into the pot. Give everything a gentle stir, season with salt and pepper to taste, and your soup is ready to warm up anyone feeling under the weather or just needing a comforting meal.

Garnishes

Topping your soup gently with freshly grated Parmesan cheese brings a subtle nutty richness and a melt-in-your-mouth creaminess that elevates each spoonful. A sprinkle of freshly cracked black pepper or finely chopped fresh herbs like parsley can also add a lovely fresh pop and color to the bowl.

Side Dishes

This soup shines wonderfully alongside a warm, crusty baguette or some garlic breadsticks, perfect for soaking up every last drop. A crisp mixed green salad with a light vinaigrette balances the comforting, creamy texture with brightness and crunch, creating a satisfying meal experience.

Creative Ways to Present

For an inviting presentation, serve the soup in rustic bowls and finish with a small drizzle of good-quality olive oil or a sprinkle of crushed red pepper flakes for a little heat. If you're hosting, consider serving it in mini soup crocks or even hollowed-out bread bowls for a stunning centerpiece that invites everyone to dig in.

Make Ahead and Storage

Storing Leftovers

Leftover Italian Penicillin Soup Recipe keeps beautifully in the refrigerator for up to 3 days when stored in an airtight container. The flavors often deepen overnight, making the next day’s lunch even more comforting and delicious.

Freezing

This soup freezes well for up to 2 months. For best results, freeze the broth and shredded chicken separately from the pasta if possible, as pasta can become mushy after thawing. Simply reheat the broth with chicken and add freshly cooked pasta when ready to enjoy.

Reheating

Reheat your soup gently on the stove over medium-low heat, stirring occasionally until hot. If the soup has thickened too much in the fridge, add a splash of water or chicken broth to bring back the perfect consistency. Add fresh pasta as needed for the best texture.

FAQs

Can I use other types of pasta in the Italian Penicillin Soup Recipe?

Absolutely! While acini di pepe is traditional for this soup’s delicate texture, small pastas like ditalini or orzo work wonderfully as well. Just keep an eye on cooking times as some shapes cook faster than others.

Is the parmesan rind necessary?

No, the parmesan rind is optional, but it adds a lovely umami depth to the broth. If you don’t have one on hand, the soup will still be flavorful with the chicken broth and vegetables alone.

Can I make this soup vegetarian?

This recipe relies heavily on chicken for its rich flavor, but for a vegetarian version, you could substitute the chicken broth and carcass with a hearty vegetable broth and add extra vegetables or legumes for protein.

What if I don't have a chicken carcass?

You can use leftover chicken bones from a roast chicken or simply increase the amount of chicken broth and shredded cooked chicken in the recipe to maintain that rich flavor.

How thick is the soup supposed to be?

The Italian Penicillin Soup Recipe results in a smooth, slightly thick broth thanks to the pureed vegetables, but it should still be spoonable and comforting, not as thick as a stew. Adjust broth or water to achieve your preferred consistency.
