-
1 tsp salt

Black pepper, to taste
-
8 cups (1.9 liters) chicken or vegetable broth

1¼ cups pastina (or orzo, stelline, ditalini)

Juice of 1 lemon (more to taste)

Freshly grated Parmesan cheese, for serving

¼ cup chopped parsley (optional)
Instructions
-
Sauté base: Heat olive oil in a large pot over medium heat. Add carrots, onion, garlic, and celery. Season with salt and pepper. Cook 4–5 minutes until softened.
-
Simmer: Pour in broth and add Parmesan rind. Bring to a boil, then reduce to low and simmer, covered, for 25–30 minutes.
-
Blend: Remove Parmesan rind. Purée the soup with an immersion blender (or in batches) until smooth.
-

Notes
Parmesan rind adds depth but can be omitted.
Use chicken broth for richness or vegetable broth to keep it vegetarian.
For chunkier soup, blend only part of the veggies.
Any small pasta works if you don’t have pastina.
Freeze without pasta for best results; add fresh pastina when reheating.

Tips for Making This Healing Italian Soup
Think of this recipe as your flexible friend—it’s forgiving and adapts to what you have in the pantry. Don’t stress if you’re missing something.
-
Parmesan rind: Adds depth, but skip it if you don’t have one.
-
Broth choice: Chicken broth gives a richer flavor, while vegetable broth keeps it vegetarian.
-
Lemon juice: Start with one, but if your taste buds want more zing, squeeze away!
-
Texture preference: If you like a chunkier soup, don’t blend it completely. Leave some hearty veggie bits.
-
Pasta swap: Pastina is classic, but orzo or even broken spaghetti works in a pinch.
And here’s my favorite hack: make a double batch and freeze half. Trust me—future you will be grateful when you need comfort in a hurry.
A Little Story from My Kitchen
This Italian Penicillin Soup became my go-to when my youngest was in elementary school. Every time she came home with a scratchy throat or those “Mom, I don’t feel good” eyes, I’d whip up a pot. Soon, it became less about colds and more about comfort. Bad day at work? Soup. Rainy afternoon? Soup. Friends dropping by unexpectedly? Soup.
Cooking this soup taught me something sweet about motherhood—it’s not always the big gestures that matter most. Sometimes it’s a simple bowl of pastina soup, served with love, that makes everyone feel cared for. Even now, when my grown kids come home, they’ll peek in the pot and ask, “Is that the soup?” That’s when I know it’s not just a recipe, it’s a memory simmering away.
What to Serve with Italian Penicillin Soup
This soup shines on its own, but if you want to turn it into a complete meal, here are some ideas:
-
Crusty bread: Perfect for soaking up that lemony broth.
-
Simple green salad: A little crunch balances the creamy texture.
-
Grilled cheese or panini: Because sometimes we all need that soup-and-sandwich magic.
-
Roasted veggies: Caramelized Brussels sprouts or roasted zucchini pair beautifully.
If you’re making it for company, add a bottle of crisp white wine and call it a feast. If it’s just for you? Pajamas, soup, and Netflix work perfectly.
How to Store and Reheat
Soup is one of those gifts that keeps on giving, and this recipe stores like a champ.
-
In the fridge: Cool completely, then store in an airtight container for up to 4 days.
-
In the freezer: Freeze without the pasta for best results (pasta tends to soak up liquid). Store up to 3 months. When ready, thaw, reheat, and add fresh pasta.
-
Reheating tip: Warm gently on the stove over medium heat, adding a splash of broth or water if it thickens too much.
Pro tip: Portion leftovers into single servings before freezing. That way, you’ve got ready-made comfort meals whenever you need them.
FAQs About Italian Penicillin Soup
Can I make this vegetarian?
Yes! Just use vegetable broth and skip the Parmesan rind, or use a vegetarian hard cheese.
Can I substitute another pasta?
Absolutely. Orzo, stelline, ditalini, or even broken-up spaghetti all work beautifully.
How do I keep it from turning too thick?
The pastina soaks up liquid as it sits. Add extra broth or water when reheating to bring back the right consistency.
Can I add chicken for more protein?
Of course! Shredded rotisserie chicken stirred in at the end is a great shortcut.
