Summary:
This cozy Italian-inspired chicken soup is packed with immune-supportive ingredients like garlic, rosemary, thyme, and vibrant vegetables.

Ingredients for Classic Italian Penicillin Soup
This soup is all about layering flavor and healing — from the savory base to the immune-supporting herbs and veggies. Here’s what you’ll need:
- 1 tbsp olive oil – heart-healthy base that carries the aromatics
- 1 medium yellow onion, diced – adds sweetness and depth
- 3 cloves garlic, minced – nature’s antibiotic; don’t skimp
- 2 large carrots, peeled and sliced – sweetness and texture
- 2 celery stalks, sliced – for that classic soup aroma
- 1 parsnip, peeled and chopped (optional) – adds earthy sweetness
- 4 bone-in, skin-on chicken thighs – deep flavor and collagen richness
- 6 cups low-sodium chicken broth – ideally homemade or high-quality store-bought
- 1 sprig fresh rosemary – anti-inflammatory and aromatic
- 2 sprigs fresh thyme – calming and subtle
- 1 bay leaf – rounds out the broth beautifully
- Salt & freshly ground pepper to taste
- 1 cup chopped spinach or kale – added at the end for freshness
- Juice of ½ lemon – for brightness and a vitamin C kick
- (Optional) Parmesan rind – drop in during simmering for a deep umami layer
- (Optional) Cooked pasta or rice – if you want a more filling version
Ingredient Notes:
- Garlic & herbs: These aren’t just for flavor — garlic, rosemary, and thyme all carry immune-supportive properties backed by both tradition and science.
- Chicken thighs: Bone-in adds richness; remove bones before serving if preferred.
- Parmesan rind: This is a sneaky Italian trick — adds a creamy, salty depth that’s hard to replicate.
Can I use chicken breast instead of thighs?
Yes, but… chicken thighs offer more flavor and tenderness, especially when simmered. If using breasts, reduce simmer time to avoid dryness and consider adding a splash of olive oil at the end for richness.
Instructions: How to Make Italian Penicillin Soup
Making this soup is less about precision and more about care. Here’s how to bring this nourishing bowl to life — even when you’re not feeling 100%.
1. Sauté the aromatics
Heat the olive oil in a large soup pot or Dutch oven over medium heat. Add the diced onion and sauté for 3–4 minutes until it starts to soften. Then add the garlic, carrots, celery, and parsnip (if using). Cook another 4–5 minutes, stirring occasionally, until the veggies start to release their aroma.
2. Add chicken and herbs
Nestle the chicken thighs into the pot, skin-side down if using skin-on. Let them sear gently for 2–3 minutes. Add the rosemary, thyme, and bay leaf. If you have a parmesan rind, now’s the time to drop it in.
3. Pour in the broth
Add the chicken broth, making sure everything is just covered. Bring to a gentle boil, then immediately lower to a simmer. Partially cover the pot and let it cook for 25–30 minutes, until the chicken is tender and cooked through.
4. Shred chicken & finish the soup
Remove the chicken and set aside to cool slightly. Add spinach or kale to the soup and simmer 5 more minutes. Shred the chicken (discard bones and skin), then return the meat to the pot. Stir in the lemon juice, season with salt and pepper to taste.
5. Serve and restore
Ladle into bowls and serve hot. Optional: top with a drizzle of olive oil or a grating of fresh parmesan. If you’ve cooked pasta or rice separately, add it directly to the bowl before pouring the soup over.
H3: Can I make this soup ahead of time?
Absolutely. In fact, it tastes even better the next day as the flavors meld. Store in the fridge for up to 4 days or freeze for up to 2 months. If freezing, omit any added pasta or greens until reheating.
Tips & Tricks for Cooking (Especially When You’re Sick)
Let’s be real — when you’re run-down, you don’t want complicated steps or extra dishes. These tricks are here to help you get maximum healing with minimum fuss.
🥣 When You’re Too Sick to Cook
- Chop once, eat twice: Double the chopped veggies and freeze half for next time.
- Use pre-chopped or frozen veggies: No shame in saving your energy.
- Let the soup cool and refrigerate in mason jars — they’re easy to grab, heat, and sip from directly.
- Make it in a slow cooker: Dump everything in (except the greens and lemon) and cook on low for 6–7 hours. Add greens and lemon at the end.
🍲 For Flavor and Comfort
- Don’t rush the simmer. This is where the healing happens — low and slow lets the flavors develop and the collagen release from the bones.
- Parmesan rind = magic. It melts down into the broth, adding a depth that’s way beyond salt.
- Add fresh herbs just before serving for a second layer of brightness and aroma.
How do I make it more filling without overcomplicating it?
If you’re feeding a family (or a ravenous version of yourself), stir in cooked small pasta (like orzo or ditalini), rice, or even canned white beans at the end. You can also toast some rustic bread and rub it with garlic for a cozy sidekick.
Substitutions & Variations
Whether you’re dealing with dietary restrictions, picky eaters, or just running low on ingredients, this soup is remarkably forgiving. Here’s how to make it yours.
🥬 Make It Vegetarian (Still Healing!)
- Swap chicken for cannellini beans or chickpeas for protein and texture.
- Use a rich vegetable broth (think: roasted veggie base or miso-enhanced for depth).
- Add umami boosts like nutritional yeast or a splash of tamari.
- Toss in extra immune-supporting veggies like mushrooms, cabbage, or fennel.
🧒 Kid-Friendly Tweaks
- Skip the greens and add tiny pasta shapes or diced potatoes.
- Use boneless chicken breast if they’re picky about bones or dark meat.
- Blend part of the broth for a smoother texture if they’re texture-sensitive.
🧂 Low-Sodium or Clean-Eating Adjustments
- Choose unsalted broth and control the seasoning yourself.
- Use herbs and citrus instead of extra salt for flavor.
- Avoid processed add-ins like bouillon cubes unless low-sodium or clean-label.
🍋 Want it spicy?
Add a pinch of chili flakes, or stir in a spoonful of Calabrian chili paste for a southern Italian kick — perfect for clearing sinuses.
What if I don’t have fresh herbs?
No problem — use dried herbs, but reduce the quantity:
- 1 tsp dried rosemary = 1 sprig fresh
- 1 tsp dried thyme = 2 fresh sprigs
Pro tip: crush dried herbs between your palms before adding them to release the oils.
Frequently Asked Questions
Can I make this in a slow cooker?
Yes — and it’s perfect when you’re low on energy. Just toss everything (except the greens and lemon juice) into the slow cooker. Cook on low for 6–7 hours or high for 3–4 hours. Add the greens and lemon juice during the last 10–15 minutes before serving. Shred the chicken and return it to the pot. Done.
How long does this soup last in the fridge?
Up to 4 days, covered tightly in the fridge. In fact, the flavor deepens over time, so leftovers can taste even better. Just reheat gently over the stove or in the microwave. If you’ve added pasta, store it separately to avoid mushiness.
Can I freeze this soup?
Absolutely. Freeze it without the greens and pasta (they don’t freeze well). Use freezer-safe containers or zip-top bags, label them, and store for up to 2 months. Thaw overnight in the fridge or reheat directly from frozen on the stove.
What’s the best way to serve it?
A big warm bowl with a chunk of rustic bread is traditional. But if you’re too sick to chew much, go minimal: soup alone with a spoon and a blanket. You can also serve it over rice, noodles, or even mashed potatoes for comfort-food fusion.
