Nonna’s Penicillin Soup – The Cozy Italian Soup Everyone Needs This Winter
When we were kids and one of us got sick, my Nonna had one answer for everything: garlic. Sniffles? Have some garlic. Sore throat? More garlic. Tummy ache? She would literally tape a clove of garlic to our belly buttons. I’m not kidding! 😂
Nonna believed garlic could cure anything, and this soup is her love in a bowl. That’s why I call it Nonna’s Penicillin Soup. It’s the bowl I reach for whenever someone in my house is feeling run down.
It’s a light, golden broth loaded with garlic, tender zucchini, fresh thyme and those tiny little pastina noodles that make every spoonful feel like a hug. A squeeze of lemon, a little Parmigiano-Reggiano and some fresh parsley on top, and you’ve got pure comfort in a bowl. 🍲
The best part? It’s so easy to make. It’s all made in one pot, and the cooking takes less than 20 minutes. Plus, it freezes beautifully. I always make a big batch ahead of time and tuck a few containers in the freezer so I have it on hand for the winter months, a rainy day, or whenever someone needs a little extra TLC.
Why I Love This Soup
This is the soup I make the minute the weather turns, or the second I hear a cough in the house. It’s simple, real food made with ingredients you probably already have, and it tastes like it simmered all day.
It is:
- Loaded with garlic (six whole cloves!) for that classic Nonna flavor
- Light, brothy and soothing, but still satisfying thanks to the pastina
- Packed with veggies: onion, celery and plenty of zucchini
- Naturally plant-based and easy to make vegan
- Ready in one pot with less than 20 minutes of cooking
- Freezer-friendly and perfect for meal prep
- Kid-approved (and dog-approved, if you ask my pup Luca, who waited very patiently by the kitchen table for his turn!)
How to Serve It
This soup is wonderful just as it is, but the toppings are what make it Nonna’s. I finish every bowl with:
- A little squeeze of fresh lemon to brighten the broth
- A sprinkle of freshly grated Parmigiano-Reggiano (or your favorite vegan parmesan)
- A little chopped fresh parsley
- A crack of black pepper
For a heartier meal, serve it with a slice of crusty sourdough or my Cheesy Garlic Bread for dipping, and a simple green salad on the side.
The Secret Ingredient: Garlic
Nonna may not have known the science, but she was onto something. Garlic has been used as a folk remedy for centuries, and today it’s being studied for its natural antibacterial, antiviral and anti-inflammatory compounds, especially allicin, which forms when you crush or chop a fresh clove.
That’s why I press my garlic right into the pot. Crushing it releases those compounds and gives the broth a deep, mellow garlic flavor once it’s gently sautéed in olive oil.
Now, of course, this soup isn’t actual penicillin! But a warm, garlicky bowl full of vegetables, herbs and broth is one of the most comforting things you can make when you’re feeling under the weather, and it’s a delicious way to support your body all season long.
Nourishing Comfort for Women Over 50
As we get older, I think it’s more important than ever to eat meals that are gentle, hydrating and full of real ingredients. This soup checks every box:
- Hydrating: A big bowl of broth helps you get more fluids in, especially in the dry winter months.
- Light but filling: The pastina adds just enough satisfying carbs to keep you warm and full without feeling heavy.
- Veggie-forward: Zucchini, celery, onion and garlic add fiber, vitamins and antioxidants to every spoonful.
- Easy to digest: Soft vegetables and a simple broth are perfect on days when your appetite is low.
Want more protein? Stir in a can of rinsed cannellini beans or some cubed tofu with the zucchini, or swirl in an egg at the end for an Italian stracciatella-style twist.

Christine’s Cooking Tips
- Can’t find pastina? Pastina can be tricky to track down at some grocery stores. Look for acini di pepe instead. It’s the same kind of tiny, round Italian pasta and works perfectly. Stelline (little stars) or orzo are great swaps too.
- Don’t brown the garlic: Keep the heat medium-low and stir the garlic constantly. You want it soft, fragrant and golden, never dark, or the broth can turn bitter.
- Wait for the boil: Add the pastina only once the broth is at a full boil, then stir often for the first few minutes so the tiny noodles don’t clump or stick to the bottom.
- Don’t overcook the zucchini: Cut it into chunky pieces so it stays tender with a little bite, not mushy.
- Taste before you salt: Bouillon bases and store-bought broths vary a lot in sodium, so season at the very end.
- Make it gluten-free: Use a gluten-free small pasta or swap in ½ cup of rice and simmer until tender.
- Make it vegan: The soup itself is plant-based. Just top it with vegan parmesan or nutritional yeast instead of Parmigiano-Reggiano.
Nutrition
Storage and Freezing
I always recommend making this soup ahead of time. It’s such a gift to yourself on a busy or sick day!
- Fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Freezer: Let the soup cool completely, then ladle it into freezer-safe containers, leaving a little room at the top. Freeze for up to 3 months.
- Reheating: Thaw overnight in the fridge, then warm gently on the stovetop. The pastina keeps soaking up broth as it sits, so add a splash of broth or water as you reheat.
- Meal-prep tip: If you know you’re freezing most of the batch, you can cook the pastina separately and add it to each bowl when you serve. It keeps the noodles perfectly tender.
Why This Soup Is a Nutrition Powerhouse
Garlic for Immune Support
Garlic is the star of Nonna’s soup for a reason. It’s rich in sulfur compounds like allicin that have natural antibacterial, antiviral and anti-inflammatory properties, which is why it’s been a go-to home remedy for generations.
Zucchini for Vitamin C and Healthy Digestion
Zucchini adds vitamin C for immune support and fiber for healthy digestion. It’s also mostly water, so it keeps the soup light and hydrating.
Onion and Celery for Antioxidants
This classic Italian soup base adds more than flavor. Onions contain the antioxidant quercetin, and celery brings vitamin K, potassium and a little extra fiber.
Fresh Thyme and Bay Leaves for Flavor with Benefits
Thyme contains thymol, a natural compound with antioxidant and antimicrobial properties. Together with the bay leaves, it gives the broth that cozy, slow-simmered taste without any extra salt or fat.
Lemon for a Vitamin C Boost
That final squeeze of lemon isn’t just for flavor! It brightens up the whole bowl and adds a little extra vitamin C.
Extra-Virgin Olive Oil for Heart Health
Extra-virgin olive oil is full of monounsaturated fats and polyphenols that support heart health and help your body absorb the nutrients in all those veggies.
Final Thoughts
This soup is so much more than a recipe to me. Every time I make it, I think of my Nonna in her kitchen, loading us up with garlic and love. It’s simple, nourishing, comforting food, the kind that warms you from the inside out and makes your whole house smell incredible.
Whether you’re fighting off a cold, craving something cozy on a rainy day, or just want an easy, healthy dinner, I hope Nonna’s Penicillin Soup becomes a staple in your home like it is in mine.
