Ingredients You’ll Need
Great food starts with great ingredients, and this soup is a wonderful example of how simple, fresh ingredients come together to create something truly special. Each component here plays an essential role in building layers of flavor, texture, and color that make the Italian Penicillin Soup Recipe so irresistible.
- 2 tablespoons olive oil: This is the flavorful foundation for the sautéed veggies that build the soup’s depth.
- 1 small yellow onion (diced): Adds a subtle sweetness and richness once softened.
- 3 garlic cloves (minced): Provides that classic aromatic punch we all crave in Italian cooking.
- 2 carrots (peeled and sliced): For a touch of natural sweetness and a lovely pop of orange color.
- 2 celery stalks (sliced): Brings crunch and mild earthiness balancing the vegetables.
- 1 teaspoon dried oregano: This herb adds a warm, slightly peppery Italian aroma and taste.
- 1/2 teaspoon crushed red pepper flakes (optional): Gifts just enough heat for those who like a little kick.
- 6 cups low-sodium chicken broth: The flavorful liquid base that ties everything together without excess saltiness.
- 1 1/2 cups cooked shredded chicken: Tender and protein-packed, it makes the soup hearty and satisfying.
- 1 cup small pasta (like ditalini or orzo): Adds chewiness and helps soak up the delicious broth.
- 1 (14.5 oz) can diced tomatoes (with juice): Brings brightness, acidity, and savory tomato goodness.
- 2 cups chopped kale or spinach: For that fresh, green goodness that wilts perfectly into the soup.
- Salt and black pepper to taste: Essential seasonings to balance and enhance all flavors.
- 1/4 cup chopped fresh parsley: Adds a burst of fresh herbaceous brightness at the end.
- 1/2 cup grated Parmesan cheese: The salty, nutty finish that brings the soup to another level.
- Juice of 1/2 lemon: This final touch wakes up the flavors with a lively citrusy zing.
How to Make Italian Penicillin Soup Recipe
Step 1: Sauté the Vegetables
Start by heating the olive oil in a large pot over medium heat. Once shimmering, add the diced onion, minced garlic, sliced carrots, and celery. Allow them to gently sauté for about 5 to 7 minutes until they soften and mellow, releasing their natural sweetness and wonderful aroma.
Step 2: Add Herbs and Spices
Next, sprinkle in the dried oregano and crushed red pepper flakes if you like a touch of heat. Stir everything together and cook for another minute so the herbs bloom and the spice infuses the vegetables, creating a flavorful base for your soup.
Step 3: Pour in Broth and Simmer
Slowly pour in the low-sodium chicken broth and bring the mixture to a gentle simmer. This step is crucial because the broth will carry the flavors of every ingredient. Let it warm through as you prepare the next components.
Step 4: Add Chicken, Tomatoes, and Pasta
Now it’s time to stir in the cooked shredded chicken, canned diced tomatoes with their juice, and your small pasta choice like ditalini or orzo. Simmer everything for about 10 minutes or until the pasta is tender but still has a slight bite to it — that perfect al dente texture that makes all the difference.
Step 5: Incorporate Greens and Season
Once the pasta is just right, add in the chopped kale or spinach and allow it to wilt gently over 2 to 3 minutes. Taste the soup and season with salt and black pepper as needed to bring out all those savory notes.
Step 6: Finish with Fresh Herbs, Cheese, and Lemon
Finally, remove the soup from heat and stir in the chopped fresh parsley, grated Parmesan cheese, and the juice of half a lemon. These finishing touches brighten the soup and add a creamy, tangy depth that makes the Italian Penicillin Soup Recipe unforgettable.
