Oh, honey, let me tell you about my Italian Penicillin Soup – it’s the kind of magic that cures more than just sniffles. When my grandkids come over with red noses or my neighbor feels under the weather, this is what I ladle into their bowls. There’s something about the way garlic and lemon dance together in this broth that just makes everything better. My Nonna used to say this soup could “mend a broken heart” – and after sixty years of making it, I believe her. It’s not fancy, but those rough-chopped vegetables and that tiny pasta bobbing in golden broth? Pure comfort in a bowl.

Ingredients for Italian Penicillin Soup
Now, let’s gather our simple but mighty ingredients – this is where the magic starts! I always tell my grandkids, “Good soup begins with good stuff.” Here’s what you’ll need:

- 3 Tbsp olive oil – the good, fruity kind if you’ve got it
- 3 large carrots, peeled and roughly chopped (don’t stress about perfect pieces)
- 1 yellow onion, quartered – skins off, tears are optional!
- 5 cloves garlic, peeled – yes, five! This is medicine, remember?
- 3 ribs celery, halved – leaves and all for extra flavor
- 1 tsp salt plus fresh black pepper – to taste
- Parmesan rind (optional but oh-so-worth it) – dig it out of your cheese drawer
- 8 cups chicken or vegetable broth – homemade if you’re fancy, boxed works fine
- 1 ¼ cup pastina – or any tiny pasta shape you’ve got
- 1 lemon – we’ll use the juice to brighten everything up
For serving: freshly grated Parmesan, more black pepper, maybe a drizzle of olive oil if you’re feeling fancy, and chopped parsley if you want to impress someone.
How to Make Italian Penicillin Soup
Alright, let’s get cooking! This soup comes together in three simple acts—just like my favorite Italian operas, but with far less drama. Follow these steps, and you’ll have a pot of golden, soul-warming goodness in no time.

Preparing the Vegetables
First, grab your biggest, heaviest pot—the one that’s seen generations of soups. Heat that olive oil over medium until it shimmers slightly (test with a carrot piece—it should sizzle gently). Toss in all your chopped veggies—carrots, onion, garlic, celery—plus the salt and pepper. Don’t stir right away! Let them sit for a minute to get a little color. That light browning? That’s where the flavor magic happens. Stir occasionally for 4-5 minutes until everything smells sweet and the onions turn translucent. (Your kitchen should smell like an Italian grandmother’s hug by now.)
Simmering the Soup
Now, the transformation begins! Pour in your broth and drop in that precious parmesan rind—it’ll melt into the liquid like a secret ingredient. Bring everything to a lively boil, then immediately lower the heat to a gentle simmer. Cover the pot (leave a tiny crack for steam) and let it bubble away for 25-30 minutes. The vegetables should be tender enough to squish with a spoon. That parmesan rind? It’ll have worked its umami magic—fish it out now; it’s earned its retirement.
Blending and Finishing
Time for the fun part! Use an immersion blender right in the pot (or carefully transfer to a regular blender in batches) to puree until velvety smooth. No lumps! Return to low heat and stir in the pastina—it’ll cook in just 8-10 minutes. Here’s the key: turn off the heat when the pasta’s al dente (it’ll keep softening in the hot broth). Finally, squeeze in that lemon juice—start with half, taste, and add more until the soup sings with bright, cozy flavor. Serve immediately with snowy parmesan and a grind of black pepper. Mangia!

Tips for the Best Italian Penicillin Soup
Listen, after sixty years of making this soup, I’ve learned a few tricks that make all the difference! First – if you know you’ll have leftovers, cook the pastina separately and add it to each bowl. That way, your noodles won’t turn into mush overnight. (Trust me, no one wants a pasta sponge in their soup.)

Second – don’t be shy with the lemon! That bright tang is what makes this soup special. I always start with half a lemon and taste as I go – sometimes that whole lemon ends up in there!
And here’s my secret: right before serving, drizzle a little best-quality olive oil on top. It adds this luxurious silkiness that makes the soup feel extra special. Oh, and save those parmesan rinds in your freezer – they’re gold for soups!
Variations of Italian Penicillin Soup
Oh, don’t be afraid to play with this recipe – that’s how traditions grow! My granddaughter swaps pastina for orzo when she’s feeling fancy, and you know what? It works beautifully. Toss in a handful of spinach or kale at the end if you want some greens (just wilt them right in the hot broth). Feeling adventurous? Try cannellini beans instead of pasta for a protein boost. The beauty of this soup is how forgiving it is – make it yours! If you’re looking for more comforting recipes like this, check out our collection of recipes.
Serving Suggestions for Italian Penicillin Soup
Oh, let me tell you how we serve this soup in my house – it’s practically a ceremony! A big, crusty loaf of Italian bread is non-negotiable – perfect for sopping up every last drop of that golden broth. Sometimes I’ll add a simple arugula salad with lemon vinaigrette on the side for something fresh. On really special days? I’ll float a few homemade garlic croutons right on top – they soak up the soup while staying just crisp enough. And always, always extra grated parmesan at the table – because as my Nonna used to say, “There’s no such thing as too much cheese!”
Storing and Reheating Italian Penicillin Soup
Now, let’s talk leftovers – because this soup tastes even better the next day! Store it in airtight containers in the fridge for up to 4 days, but here’s my golden rule: keep the pasta separate if you can. When reheating, warm the broth gently on the stove (microwaving works too, but stir often) and add fresh-cooked pastina to each bowl. Want to freeze it? Just leave out the pasta entirely – frozen noodles turn to mush. Thaw overnight in the fridge, then simmer with your favorite tiny pasta when ready to serve.
Nutritional Information
Now, I’m no nutritionist, but here’s the general idea – each cozy bowl of Italian Penicillin Soup packs about 250 calories with plenty of vitamins from those fresh veggies. Remember, these numbers dance around depending on your broth and cheese choices. Nonna always said, “Good food feeds more than the body,” and I think she was right!

Frequently Asked Questions
Q1. Can I freeze Italian Penicillin Soup?
Absolutely! Just remember to leave out the pasta before freezing. The broth and vegetables freeze beautifully for up to 3 months. When you’re ready, thaw overnight in the fridge and cook fresh pasta when reheating – that way you’ll avoid mushy noodles.
Q2. What’s the best substitute for pastina?
Oh honey, use whatever tiny pasta you’ve got! Orzo works wonderfully, as do small shells or even broken-up spaghetti pieces. In a pinch, I’ve used rice or pearled couscous – just adjust the cooking time accordingly. If you’re looking for other great soup ideas, check out Grandma’s Chicken Taco Soup recipe.
Q3. My soup turned out too thick. What should I do?
No worries – this happens to me sometimes too! Just whisk in a little extra broth or hot water until it reaches your perfect consistency. Think of it like adjusting a sauce – add liquid gradually until it’s just right.
Q4. Can I make this soup vegetarian?
Of course! Simply use vegetable broth instead of chicken broth. The parmesan rind is optional, but it does add wonderful depth – just check that it’s vegetarian-friendly if that’s important to you.
Q5. Why do you add lemon at the end?
That bright pop of acidity is like magic – it wakes up all the flavors! Adding it at the end preserves its fresh taste. Start with half a lemon, taste, and add more until the soup makes you smile.
