3. Add the diced onion, carrots, and celery; sauté 5 to 7 minutes until the vegetables are soft and the onion is translucent.
4. Add the minced garlic and cook about 1 minute until fragrant, avoiding browning.
5. Pour in 8 cups low-sodium chicken (or vegetable) broth; add the whole bone-in, skin-on chicken breast, 2 bay leaves, 1 teaspoon dried oregano, 1/2 teaspoon dried thyme, and 1/4 teaspoon red pepper flakes (optional).

Helpful Tips and Tweaks

This is a soup that rewards patience, but I know life gets busy. So here are some handy tips and tweaks to make your Italian Penicillin Soup a bit easier or more personalized without losing that cozy, soulful vibe.

Cooking Tips That Make a Difference

• Opt for bone-in chicken: The bones and skin add so much flavor to the broth you just can’t get from boneless cuts.
• Avoid browning the garlic: Just cook it until fragrant. Too much color can bring bitterness and throw off the soup’s delicate balance.
• Keep it simmering gently: Boiling too hard can toughen your chicken and cloud the broth. Low and slow is the way to go.
• Don’t overcook the pasta: Cook it until al dente so it doesn’t get mushy if you reheat leftovers.

Serving Suggestions

• Always finish with lemon and parsley: It brightens the soup and balances those savory flavors like magic.
• Add cheese and olive oil last minute: A fresh drizzle of quality olive oil and a sprinkle of Parmigiano-Reggiano take this soup to a whole new delicious level.
• Serve with crusty bread: Grab a rustic Italian loaf, sourdough, or even garlic focaccia—or make an easy 2-ingredient cottage cheese flatbread—to soak up every last drop of broth.

Storage & Reheating Tips

Freeze without pasta: If you want to make a big batch to freeze, leave out the pasta. When reheating, add freshly cooked pasta for the best texture.

Keep leftovers in the fridge up to 3 days: The flavors will deepen, but pasta will continue absorbing broth. Add a splash of broth or water when reheating to loosen it back up.

Ways to Customize Your Soup

One of the great things about Italian Penicillin Soup is how flexible it is. Whether you have dietary needs to consider or just want to change it up, you can adapt this soup while keeping its heart and soul.

Vegetarian Twist

• Leave out the chicken and use vegetable broth.
• Add a can of white beans (cannellini or navy beans work great) once the veggies are soft. Let them heat gently to soak up the flavors.
• A splash of miso paste stirred in at the end adds savory depth that mimics the richness of chicken broth.

Gluten-Free Option

• Swap out the pasta for cooked rice, like jasmine, basmati, or arborio.
• Or skip grains entirely and add cubed gold potatoes or diced zucchini, which will soften beautifully and soak up the broth.

Dairy-Free Version

• Simply leave off the cheese garnish.
• For a cheesy taste without dairy, sprinkle in some nutritional yeast just before serving—it adds umami and warmth without lactose.

Kid-Friendly Adaptations

• Pick mild pasta shapes kids love, like mini shells, elbow macaroni, or tiny orzo (see our Warm Chicken Orzo Tomato Soup for how well orzo works in brothy soups).
• Skip the red pepper flakes and top with mild grated cheese like mozzarella or Monterey Jack for a gentle flavor.

Bonus Flavor Swaps

For a fresh Italian spin, stir in a spoonful of pesto at the end instead of lemon and parsley.

If you want a zing and extra immune support, add a few slices of fresh ginger while simmering.

For some greens, toss in a handful of baby spinach or kale just before serving to add a bright, earthy note.

Storing, Freezing, and Reheating

Let the soup cool down to close to room temperature (no more than 2 hours), then put it into airtight containers to refrigerate or freeze. Use shallow containers so it cools faster and mark the date on your container.

• Refrigerate: Keep in the fridge for up to 3 days. Flavors deepen but the pasta will soak up broth and soften over time.
• Freeze: For best texture, freeze the soup without pasta. Use airtight freezer-safe containers or heavy-duty bags. Freeze for up to 3 months and leave a bit of space for liquid to expand.

Make‑ahead tips: You can make the chicken broth and simmer the chicken a day or two ahead and refrigerate, or freeze the broth and shredded chicken separately. Cook pasta fresh when reheating for best results, though you can store it separately for 1–2 days if needed.

1. Reheat on the stovetop: If frozen, thaw in the fridge overnight or reheat straight from frozen over low to medium heat. Add broth or water if it’s too thick. Heat until steaming and hot, then stir in freshly cooked pasta to keep it from getting mushy.
2. Reheat in the microwave: Heat a single serving covered loosely in 60- to 90-second bursts, stirring in between, until hot. Add broth if needed. Finish by stirring in lemon juice and parsley right before serving.

Safety & finishing notes: Reheat soup to at least 165°F (74°C). Always add fresh lemon, parsley, and cheese after reheating to keep their flavors bright. For vegetarian versions using beans, beans might break down over time—add broth when reheating to adjust consistency.

Common Questions About the Soup

Let’s clear up a few common questions about Italian Penicillin Soup and why it has such a beloved reputation.

What is the Italian penicillin soup?

Italian Penicillin Soup is a comforting, broth-based soup that comes from Italian home cooking traditions. It’s built on a base of onion, carrot, and celery, with garlic, herbs, small pasta, and slow-cooked chicken. People lovingly call it “penicillin soup” because it’s known for its cozy, restorative powers when feeling under the weather.

Does Italian Penicillin Soup really work?

It’s not a true antibiotic, of course, but this soup can help you feel better. The warm broth keeps you hydrated and soothes, the steam helps clear congestion, and ingredients like garlic, lemon, and parsley provide immune-boosting benefits. Plus, nothing beats the emotional comfort of a warm, homemade meal when you’re sick.

Why do they call it “penicillin soup”?

The name is a playful nod to the soup’s reputation as a natural remedy. Families—especially Italian and Jewish households—often rely on it as a first line of defense for colds and flu symptoms. It’s not medicine in a literal sense, but it sure feels like it.

What is the Italian soup that cures sickness?

There isn’t one magic soup, but this version of chicken soup, with garlic, herbs, lemon, and love, is a favorite go-to for feeling better. It’s called Italian Penicillin Soup because of how nurturing and restorative it is. Other healing Italian soups include brodo (clear broth) and stracciatella (egg-drop soup), but this hits the sweet spot of comfort, nutrition, and flavor.
