Italian Penicillin Soup is what I make when someone in my house starts sniffling, when the weather turns weird, or when I just want dinner to feel like a warm blanket. You know those days when you are tired, your throat feels scratchy, and even deciding what to cook feels like too much. This is the kind of recipe that does not ask for fancy skills, just a pot and a little patience. It is simple, cozy, and somehow it always tastes like it is doing you a favor. I learned my version from an Italian friend’s nonna, and I have been slightly obsessed ever since.

What Is Italian Penicillin Soup?
Italian Penicillin Soup is basically the Italian comfort answer to feeling under the weather. It is not actual medicine, of course, but people call it that because it is soothing, hydrating, and full of ingredients that make you feel taken care of.
In a lot of families, it shows up when someone is sick, stressed, or run down. Think of a light chicken soup, but with an Italian accent: a gentle broth, tender chicken, aromatics like onion and garlic, and often a little pasta or rice to make it feel like a real meal. Some versions add lemon, some add greens, and some keep it super simple with just broth and tiny pasta.
What I love most is that it tastes clean and comforting at the same time. It is warm, savory, and easy to eat even if you do not have much of an appetite. And if you have ever had a nonna hand you a bowl of soup like it is a cure for everything, you already get the vibe.
This soup is not complicated, but every ingredient earns its spot. The goal is flavor without heaviness.
The healing lineup in plain English
- Chicken: Adds protein and makes the broth richer. Thighs stay juicy, breasts are leaner. Either works.
- Onion, carrot, celery: The classic base that makes the whole pot taste like home. Do not skip if you can help it.
- Garlic: Gives that cozy, savory bite. I use more when someone is sick.
- Chicken broth: Store bought is fine, but choose low sodium so you can control the salt.
- Small pasta (like ditalini, stelline, or orzo): Makes it filling and extra comforting.
- Lemon: Wakes everything up. A little squeeze at the end makes the soup taste brighter.
- Parsley: Fresh and clean tasting. It makes the bowl feel less heavy.
- Parmigiano Reggiano: Optional, but a little sprinkle on top is magic.
A quick note from my own trial and error: if your broth tastes flat, it usually needs salt, a squeeze of lemon, or both. That small adjustment turns it from fine to wow.
Step-by-Step Recipe
This is the way I make it at home, in a regular pot, with regular weeknight energy. It is forgiving, so do not overthink it.
Ingredients (serves about 4 to 6)
- 1 tablespoon olive oil
- 1 medium onion, chopped
- 2 carrots, chopped
- 2 celery stalks, chopped
- 4 cloves garlic, minced
- 1 to 1.5 pounds chicken thighs or breasts
- 8 cups chicken broth (low sodium if possible)
- 1 bay leaf (optional but nice)
- 3/4 cup small pasta (orzo, ditalini, tiny shells, stelline)
- Salt and black pepper
- 1 lemon (zest optional, juice recommended)
- Chopped fresh parsley
- Grated Parmigiano Reggiano, for serving (optional)
Directions
1) Warm the olive oil in a large pot over medium heat. Add onion, carrot, and celery. Stir and let them soften for about 6 to 8 minutes. You want them glossy and sweet smelling, not browned.
2) Add the garlic and stir for about 30 seconds. As soon as it smells good, move on. Garlic can go from perfect to bitter fast.
3) Add the chicken, broth, and bay leaf if using. Bring it to a gentle simmer. Lower the heat so it is not boiling hard, then cover and cook for about 18 to 25 minutes, depending on the size of your chicken pieces.
4) Pull the chicken out onto a plate. Shred it with two forks, or chop it into small pieces if you prefer it neater. Put it back in the pot.
5) Bring the soup back to a steady simmer and add the pasta. Stir and cook until the pasta is just tender. Check the pasta package for timing, but start testing a minute or two early.
6) Turn off the heat. Add a pinch of salt and pepper, then squeeze in lemon juice a little at a time. Taste as you go. Finish with parsley. Serve hot, with Parmigiano on top if you want that extra comfort factor.
If you are making Italian Penicillin Soup for someone who is sick, I like to keep the pasta on the softer side and the broth a little more salty than usual. Not crazy salty, just enough to make every spoonful taste satisfying.
Pro Tips for the Best Italian Penicillin Soup
This is the part where I save you from the little mistakes I have made so you do not have to.
Keep the simmer gentle. If the soup boils like crazy, the chicken can get tougher and the broth can get cloudy. A calm simmer tastes cleaner.
Do not overcook the pasta. Pasta keeps cooking in hot broth. If you know you will have leftovers, you may want to cook the pasta separately and add it to each bowl.
Taste at the end, not just the beginning. Broth reduces a little, chicken adds flavor, pasta soaks up salt. Final seasoning matters.
Lemon is your secret weapon. Even if you think you do not like lemon in soup, try just a small squeeze. It makes everything feel fresher, especially when you are congested and flavors taste muted.
Use good broth. This soup is basically broth plus a few good things. If your broth is bland, the soup will be bland. If you can find a nice boxed broth or a good butcher stock, it shows.
I have made Italian Penicillin Soup on sleepy Sundays and on chaotic weeknights, and the biggest difference always comes down to simmering gently and tasting at the end.
Variations & Substitutions
This soup is flexible, and honestly that is why it becomes a family staple. Here are a few easy ways to change it without losing the cozy feel.
Swap the pasta: Use rice, farro, or even mashed potatoes stirred in for a thicker texture. Tiny pasta is traditional, but not required.
Add greens: A couple handfuls of spinach or chopped escarole at the end is great. It wilts fast and makes you feel extra virtuous.
Make it dairy free: Just skip the cheese. It is still delicious.
Rotisserie chicken shortcut: If you are tired, use shredded rotisserie chicken. Simmer the broth with the vegetables first, then add chicken near the end so it does not get dry.
More “cold season” vibes: Add a pinch of crushed red pepper or a little grated ginger. Not traditional for every nonna, but it can feel really good.
If you keep the base simple, it still counts as Italian Penicillin Soup in my kitchen. The point is comfort, not perfection.
Serving, Storing & Reheating
This is the kind of soup that makes you want to eat on the couch with a blanket, and I support that fully.
Serving ideas: I love it with crusty bread, saltines, or toasted garlic bread if you want to lean into comfort. A small side of simple salad is nice too, but only if you are feeling ambitious.
Storing: Cool the soup, then store in airtight containers in the fridge for up to 4 days. If the pasta is in the soup, it will soak up broth and get softer. Still tasty, just thicker.
Reheating: Warm it slowly on the stove or microwave it in short bursts, stirring in between. Add a splash of broth or water if it looks too thick. Finish with a fresh squeeze of lemon and a little parsley to bring it back to life.
Freezing: You can freeze it, but I recommend freezing the soup without pasta. Pasta can turn mushy after freezing. If you plan ahead, freeze the broth and chicken base, then cook fresh pasta when you reheat.

FAQs About Italian Penicillin Soup
Is Italian Penicillin Soup actually Italian?
The name is more of a nickname than a classic menu item. The idea of a simple chicken soup with aromatics is absolutely common in Italian home cooking, and lots of families have their own version.
Can I make it without chicken?
Yes. Use vegetable broth and add beans like cannellini for protein. It will still be soothing and hearty.
What pasta works best?
Small shapes are easiest to eat and feel most “soup like.” Orzo, ditalini, tiny shells, and stelline are all great.
Why does my soup taste bland?
Usually it needs more salt, a little more simmer time, or a squeeze of lemon. Start with salt, then try lemon. Those two fixes solve it most of the time.
Can I make it in advance for a sick friend?
Absolutely. It is one of the best make ahead meals. If you can, keep the pasta separate so the soup stays brothy when they reheat it.
Conclusion
Italian Penicillin Soup is one of those recipes that earns a permanent spot in your routine because it is easy, reliable, and genuinely comforting.
