Ingredients (Serves 4–6)

2 tablespoons olive oil
1 onion, finely chopped
2–3 cloves garlic, minced
2 medium carrots, diced
2 celery stalks, diced
1 small zucchini, diced (optional)
1 pound (450 g) boneless chicken breast or thighs
6 cups chicken broth or stock
1 teaspoon dried Italian herbs (oregano, basil, thyme)
Salt and pepper to taste
Fresh parsley for garnish
Optional: a squeeze of lemon for brightness

How to Make Italian Penicillin Soup

Step 1: Sauté Aromatics

Heat olive oil in a large pot over medium heat. Add onions, garlic, carrots, and celery. Sauté for 5–7 minutes until softened and fragrant.

Step 2: Add Chicken

Add the chicken pieces to the pot. Brown slightly on all sides for extra flavor.

Step 3: Pour in Broth and Herbs

Add the chicken broth and dried Italian herbs. Season with salt and pepper. Bring to a boil, then reduce heat to low and simmer for 20–25 minutes, until chicken is cooked through and vegetables are tender.

Step 4: Shred Chicken

Remove the chicken from the pot and shred it using two forks. Return the shredded chicken to the soup.

Step 5: Add Zucchini or Quick-Cooking Vegetables

If using zucchini or other delicate vegetables, add them now and simmer for an additional 5 minutes.

Step 6: Finish and Serve

Taste and adjust seasoning. Garnish with chopped parsley and a squeeze of lemon if desired. Serve hot with crusty bread or over cooked pasta for a heartier meal.

Tips for the Perfect Soup

Use homemade or high-quality chicken broth for deeper flavor.
Fresh herbs can replace dried herbs — add them at the end to preserve flavor.
For extra immunity support, add a thumb-sized piece of ginger or a pinch of turmeric.
Make it creamy: stir in a few tablespoons of Greek yogurt or cream just before serving.

Variations

Italian Chicken & Orzo Soup: Add ½ cup orzo or small pasta during the last 10 minutes of cooking.
Vegetable-Loaded Version: Add kale, spinach, or peas for extra nutrients.
Spicy Kick: Add a pinch of red chili flakes or cayenne for warmth.
Slow Cooker Version: Sauté aromatics, then combine all ingredients in a slow cooker on low for 4–6 hours.

Serving Suggestions

Serve with grated Parmesan cheese and a drizzle of olive oil.
Pair with garlic bread or a warm baguette.
Ideal for meal prep: store in airtight containers in the fridge for up to 3 days or freeze portions for up to 1 month.

Why It’s Called “Penicillin Soup”

This soup gets its nickname from its reputation as a restorative, immunity-boosting meal — similar to the way classic chicken soup has been called “Jewish penicillin.” The combination of garlic, herbs, and chicken broth is known for soothing the throat, supporting digestion, and providing warmth during illness or cold weather.

This Italian Penicillin Soup is simple, flavorful, and nourishing — a perfect example of how comfort food can also be healthy. With minimal ingredients and easy steps, it’s a soup you’ll return to again and again.
