Italian Penicillin Soup – A Nourishing, Rustic Chicken Broth with Mediterranean Flair

Inspired by the idea of “Jewish penicillin” (chicken soup) with a Mediterranean twist, Italian Penicillin Soup is a deeply comforting, herb-infused chicken broth layered with vegetables, garlic, and healing aromatics. This version nods to traditional Italian flavors like olive oil, fresh rosemary, garlic, and Parmesan, making it as soul-soothing as it is delicious.

This isn’t just a sick-day remedy—it’s a nourishing bowl of warmth and flavor that’s perfect for cool evenings, flu season, or any time you’re craving something hearty and wholesome. Think: tender shredded chicken, rich broth, vibrant greens, and a sprinkle of sharp cheese melting into each spoonful.

Rustic, simple, and deeply satisfying—Italian Penicillin Soup is food for the body and soul.

Ingredients Overview

This recipe uses humble, whole-food ingredients that each bring both flavor and nutritional benefit. Here’s a breakdown of the core elements:

• Bone-in Chicken Thighs or Drumsticks: Simmered low and slow, these add rich flavor and nutrients to the broth. The bones create collagen for a silky texture. You can also use a whole cut-up chicken.

• Extra Virgin Olive Oil: Adds depth and heart-healthy fats. Use to sauté your aromatics.

• Garlic: A key immune booster and flavor base. Use plenty—at least 6 cloves, sliced or smashed.

• Onion, Carrot, Celery (Soffritto): The Italian version of mirepoix. Provides sweetness and savory balance.

• Fresh Rosemary & Thyme: Earthy, aromatic herbs that bring Italian flavor and support digestion.

• Bay Leaves: Infuse subtle background complexity to the broth.

• Parmesan Rind: The secret ingredient. Simmered in the soup, it adds umami and a gentle nuttiness.

• Greens (Escarole, Kale, or Spinach): Adds color, texture, and nutrients. Escarole is traditional, but any tender green works.

• Lemon Juice or Zest: Brightens and balances the richness with acidity.

• Salt & Cracked Pepper: Essential for drawing out the layers of flavor.

• Small Pasta (Optional): Ditalini, orzo, or acini di pepe are lovely additions for a heartier version.

• Grated Parmesan (for garnish): Melts into the broth and adds a savory finish.

Ingredient Substitutions

• For Vegetarian Version: Use white beans or chickpeas instead of chicken, and vegetable broth.

• No Parmesan Rind? Use a small handful of shredded cheese stirred in at the end.

• Low-Carb Option: Skip the pasta and add extra greens or zucchini ribbons.

• Gluten-Free: Use gluten-free pasta or omit it altogether.

Step-by-Step Instructions

This soup comes together slowly and steadily—the key is to let the broth develop rich depth over time.

1. Sear the Chicken

In a large Dutch oven or heavy-bottomed pot, heat 2 tablespoons of olive oil over medium-high heat.

Season 2.5–3 lbs of bone-in chicken (thighs, drumsticks, or a mix) with salt and pepper.

Sear until golden brown on both sides, about 4–5 minutes per side. Remove and set aside.

2. Sauté the Aromatics

In the same pot, lower heat to medium.

Add 1 diced yellow onion, 3 diced carrots, and 2 diced celery stalks.

Cook for 5–6 minutes until softened.

Stir in 6 cloves of sliced garlic, 2 sprigs of rosemary, and 2 sprigs of thyme. Cook for 1 minute more, just until fragrant.

Optional: Add ½ teaspoon crushed red pepper for gentle heat.

3. Build the Broth

Return chicken to the pot and pour in 10 cups of cold water or unsalted chicken broth.

Add 2 bay leaves and a Parmesan rind (if using).

Bring to a gentle boil, then reduce heat and simmer uncovered for 1.5 to 2 hours, skimming foam as needed.

The broth should reduce slightly and turn golden, rich, and fragrant.

4. Shred the Chicken & Finish the Soup

Remove the chicken and let cool slightly. Discard the bones and shred the meat.

Return the shredded chicken to the pot. Remove the rosemary, thyme, and bay leaves.

Add 4 cups of chopped escarole (or spinach, kale, or chard) and simmer for 5–10 minutes until wilted and tender.

If adding pasta: cook it separately and stir into bowls just before serving so it doesn’t get mushy.

Stir in 2 tablespoons of fresh lemon juice or zest, and adjust salt and pepper to taste.

5. Serve and Garnish

Ladle into bowls and top with freshly grated Parmesan and a drizzle of olive oil.

Serve with crusty bread or focaccia for dipping.

Tips, Variations & Substitutions

• Short on Time? Use store-bought rotisserie chicken and pre-made broth. Simmer garlic, onion, herbs, and rind for 20 minutes to infuse.

• More Vegetables: Add zucchini, chopped tomatoes, or even mushrooms for extra depth.

• Bone Broth Base: For extra nourishment, simmer bones or use pre-made bone broth in place of regular stock.

• Add Beans: Cannellini beans or chickpeas add texture and protein.

• Make It Creamy: Add a splash of half-and-half or a dollop of ricotta stirred in at the end for richness.

FAQs

Q1: Can I make Italian Penicillin Soup in a slow cooker?

Yes. Add all ingredients except greens and lemon juice to your slow cooker. Cook on LOW for 6–8 hours. Add the greens and lemon during the last 20–30 minutes.

Q2: Can I freeze this soup?

Absolutely. Let it cool completely, then store in freezer-safe containers without the pasta (if using). Freeze for up to 3 months. Thaw overnight in the fridge.

Q3: What’s the best cut of chicken to use?

Bone-in thighs or drumsticks are ideal for richness and flavor. Boneless thighs also work, but won’t provide the same depth. Avoid skin-on unless you skim fat from the top.

Q4: Can I use store-bought broth?

Yes. Choose low-sodium chicken broth and simmer it with garlic, herbs, and a Parmesan rind to build more flavor.

Q5: What type of pasta should I add?

Small shapes like ditalini, orzo, or acini di pepe are traditional. Cook separately and add to individual bowls to avoid soggy leftovers.

Q6: What herbs can I substitute?

If you don’t have fresh rosemary or thyme, use ½ teaspoon each of dried. Add with the broth so they have time to infuse.

Q7: Is this soup good for colds?

Yes! It contains immune-supportive ingredients like garlic, broth, lemon, and greens. It’s hydrating, warming, and easy on the stomach—just what you need when feeling under the weather.
