Ingredients You’ll Need

Chicken & Broth

1 ½ pounds bone-in, skin-on chicken thighs
- Bone-in adds richer flavor than boneless. Use boneless thighs in a pinch and simmer 5–10 minutes less.
8 cups low sodium chicken broth
- Use a good quality boxed broth like Kettle & Fire or Pacific when you do not have homemade stock.
1 cup water, as needed, to adjust saltiness and volume

Vegetables & Aromatics

1 large yellow onion, diced
3 large carrots, peeled and sliced into coins
3 celery stalks, sliced
6 cloves garlic, minced
1 small fennel bulb, cored and thinly sliced (optional but very tasty)
1 cup chopped fresh spinach or kale
2 tablespoons fresh parsley, chopped
1 tablespoon fresh dill, chopped (or 1 teaspoon dried)

Pantry Flavor Boosters

2 tablespoons olive oil
1 tablespoon butter or ghee
- Use all olive oil to keep it dairy free.
1 teaspoon dried oregano
1 teaspoon dried basil
½ teaspoon dried thyme
½ teaspoon crushed red pepper flakes (optional, for gentle heat)
1 bay leaf
1 ¼–1 ½ teaspoons kosher salt, plus more to taste
½ teaspoon black pepper

Lemon & Finishing Touches

Zest of 1 lemon
Juice of 1–2 lemons, to taste
½ cup grated Parmesan or Pecorino Romano cheese, plus extra for serving
- Use a wedge and grate it yourself for best flavor; pre-grated works in a pinch.
2 large egg yolks (optional, for extra richness and silkiness)

Starch Options

Pick one:

1 cup small pasta like orzo, ditalini, or acini di pepe
- Use gluten free pasta if needed; cook it separately so it does not fall apart.
or ¾ cup white rice (jasmine or basmati)
or 1 ½ cups cooked cannellini beans for a higher protein, lower carb option

Equipment List

Large heavy pot or Dutch oven (at least 6 quarts)
Cutting board and sharp knife
Wooden spoon or heat safe spatula
Ladle
Small bowl and whisk (for egg yolks, if using)
Fine grater or microplane for lemon zest and cheese

Tips & Tricks

Brown the chicken skin side down first to build flavor, then remove the skin if you prefer less fat.
Sweat the onions, carrots, and celery slowly over medium heat so they soften and sweeten instead of burn.
Add the pasta or rice near the end so it stays tender but not mushy.
Cook pasta or rice separately if you plan to freeze the soup or store it for several days.
Taste and adjust lemon juice at the very end; cold taste buds on sick days often need extra brightness.
Stir egg yolks into a little hot broth first so they stay silky and do not scramble.
Keep salt light at the start, especially with store bought broth and Parmesan, then adjust at the end.
Use rotisserie chicken as a shortcut: skip the simmering step and add shredded meat directly to the soup.

How to Make Italian Penicillin Soup Recipe

Step 1: Sear the Chicken

Heat the olive oil and butter in your large pot over medium high heat. Pat the chicken thighs dry and season both sides with a pinch of salt and pepper. Lay the chicken in the pot skin side down and sear 4–5 minutes per side until the skin browns and the bottom of the pot develops browned bits.

Transfer the chicken to a plate and set it aside. Spoon off some fat if the pot looks very greasy, but keep about 1–2 tablespoons for flavor.

Step 2: Build the Aromatic Base

Lower the heat to medium. Add the onion, carrots, and celery to the pot and stir to coat them in the fat. Cook 6–8 minutes until the vegetables soften and the onions look translucent, and scrape up the browned bits as they loosen.

Add the fennel if you use it and cook 2–3 more minutes. Stir in the garlic, dried oregano, basil, thyme, red pepper flakes, and bay leaf, then cook 1 minute until the garlic smells fragrant.

Step 3: Simmer the Broth

Pour in the chicken broth and any juices that collected on the chicken plate. Add enough water to cover the chicken later and still leave room at the top of the pot. Stir, then nestle the chicken thighs and any loose skin back into the pot.

Bring the soup to a gentle boil, then lower the heat to maintain a steady simmer. Cook 20–25 minutes until the chicken cooks through and feels very tender.

Step 4: Shred the Chicken

Use tongs to lift the chicken out of the pot and place it on a cutting board. Let it cool for a few minutes so you do not burn your fingers. Pull off and discard the skin if you have not done that yet.

Shred the meat with two forks into bite size pieces and discard the bones. Keep the shredded chicken nearby while you finish the soup base.

Step 5: Cook the Starch

If you cook the pasta or rice directly in the soup, add it now. Stir in your chosen starch and keep the soup at a gentle simmer. Cook according to package directions for pasta or about 12–15 minutes for rice, until just tender.

If you cook the starch separately, bring a small pot of salted water to a boil. Cook the pasta or rice until al dente, then drain and toss with a tiny drizzle of olive oil so it does not stick. Add it to individual bowls when you serve.

Step 6: Add Greens, Herbs, and Chicken

Stir the shredded chicken back into the pot. Add the spinach or kale, parsley, and dill. Simmer 3–5 minutes until the greens wilt and the chicken heats through.

Taste and adjust salt and pepper at this point. The soup should taste savory and balanced before you add lemon and cheese.

Step 7: Finish with Lemon and Parmesan

Turn the heat to low. Stir in the lemon zest and juice of 1 lemon, then taste. Add more lemon juice if you want a brighter, “wake up my sinuses” flavor.

Sprinkle in the grated Parmesan or Pecorino and stir until it melts into the broth. Keep the soup hot but not boiling while you finish any optional steps.

Step 8: Optional Egg Yolk Enrichment

If you use egg yolks, whisk them in a small bowl. Ladle in a small amount of hot broth while you whisk constantly until the mixture feels warm and smooth. This step keeps the yolks silky.

Pour the yolk mixture back into the pot in a thin stream while you stir the soup. Keep the heat low and cook 2–3 minutes until the broth looks slightly thicker and velvety, but do not let it boil.

Step 9: Serve

Ladle the Italian Penicillin Soup Recipe into warm bowls. If you cooked pasta or rice separately, add a scoop to each bowl before you pour in the soup. Top with extra Parmesan, a sprinkle of fresh herbs, and a crack of black pepper.

Serve hot and breathe in that steamy, lemony goodness. Keep tissues nearby if your nose decides to clear itself mid-bite.

What to Serve with it?

This Italian Penicillin Soup Recipe pairs well with warm crusty bread, garlic breadsticks, or simple focaccia for dunking. Add a crisp green salad with romaine, cucumbers, cherry tomatoes, and a light vinaigrette to keep the meal fresh and balanced. You can also serve it with roasted vegetables like broccoli, carrots, or green beans for extra fiber and color.

Offer lemon wedges, extra grated cheese, and red pepper flakes at the table so everyone can customize their bowl. A mug of hot herbal tea or a sparkling water with lemon fits the cozy vibe perfectly.

Storage Options

Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
Keep pasta or rice in a separate container so it does not soak up all the broth and turn mushy.
Freeze the soup without pasta or rice in freezer safe containers or bags for up to 3 months.
Thaw frozen soup overnight in the fridge or in a bowl of cold water, then reheat gently on the stove over medium heat until hot.
Add freshly cooked pasta or rice to reheated soup, then taste and adjust lemon and salt before serving.
