Ingredients You’ll Need

Main Ingredients

2 tablespoons olive oil
1 tablespoon unsalted butter
1 medium yellow onion, finely chopped
3 medium carrots, peeled and sliced into coins
3 celery stalks, sliced
4 garlic cloves, minced
1 ½ pounds bone-in, skin-on chicken thighs
- You can use boneless thighs or rotisserie chicken as a shortcut.
8 cups low-sodium chicken broth
- Use a good-quality boxed broth; I like brands with short ingredient lists.
1 cup small pasta such as orzo, ditalini, or small shells
- Swap with white rice or brown rice if you prefer gluten free.
1 teaspoon kosher salt, plus more to taste
½ teaspoon freshly ground black pepper
1 teaspoon dried oregano
1 teaspoon dried basil
½ teaspoon dried thyme
1 bay leaf
1 small Parmesan rind (optional but highly recommended)
- Save rinds from blocks of Parmigiano Reggiano in the freezer for soups like this.
Juice of 1 large lemon, plus extra wedges for serving
Zest of 1 lemon
¼ cup fresh parsley, chopped
2 tablespoons fresh dill, chopped (optional but lovely)

Pantry Shortcuts & Substitutions

Use rotisserie chicken and boxed broth when you need speed.
Use frozen mirepoix mix instead of chopping onion, carrot, and celery.
Use pre-minced garlic from a jar if you feel under the weather and low on energy.
Swap lemon with a splash of bottled lemon juice in a pinch, then adjust to taste.

Optional Add-ins

1 to 2 cups baby spinach or chopped kale
½ teaspoon crushed red pepper flakes for gentle heat
½ cup frozen peas added at the end
Extra grated Parmesan for serving

Equipment List

Large heavy-bottomed pot or Dutch oven (at least 6-quart)
Cutting board and sharp knife
Wooden spoon or heat-safe spatula
Ladle
Tongs
Small bowl and fork for shredding chicken
Citrus zester or fine grater
Measuring cups and spoons

Tips & Tricks

Brown the chicken thighs first to build flavor and deepen the broth.
Use bone-in chicken when possible because the bones give richer flavor.
Skim off excess fat from the top of the soup with a spoon if you prefer a lighter broth.
Cook the pasta separately if you plan to store leftovers so it does not soak up all the broth.
Salt in layers: season the veggies, then the broth, then adjust again at the end.
Add lemon juice at the end of cooking so it stays bright and fresh, not bitter.
Use leftover rice or cooked pasta from the fridge to speed things up on busy nights.
Stir in fresh herbs right before serving to keep their flavor vibrant.
Taste the soup after adding Parmesan rind and adjust salt because the cheese adds saltiness.
Keep the soup at a gentle simmer, not a rolling boil, so the chicken stays tender.

How to Make Italian Penicillin Soup Recipe

Step 1: Sear the Chicken

Heat the olive oil and butter in a large pot over medium heat. Pat the chicken thighs dry with paper towels and season both sides with salt and pepper. Place the chicken in the pot skin side down and cook 4 to 5 minutes per side until the skin turns golden and the bottom of the pot picks up browned bits. Transfer the chicken to a plate and set it aside.

Step 2: Sauté the Aromatics

Add the chopped onion, carrots, and celery to the same pot. Stir and scrape up the browned bits from the bottom as the veggies release moisture. Cook 6 to 8 minutes until the onion turns translucent and the carrots start to soften. Add the minced garlic and cook 1 minute until fragrant, while you stir to prevent burning.

Step 3: Build the Broth

Sprinkle in the dried oregano, basil, thyme, and a pinch of salt and pepper. Stir to coat the vegetables in the herbs and oil. Pour in the chicken broth and stir again. Add the bay leaf and Parmesan rind if you use it.

Step 4: Simmer the Chicken

Return the seared chicken thighs and any juices from the plate to the pot. Bring the soup up to a gentle boil, then lower the heat to maintain a steady simmer. Cover the pot partially and cook 25 to 30 minutes until the chicken cooks through and feels very tender. Stir occasionally so nothing sticks to the bottom.

Step 5: Shred the Chicken

Use tongs to lift the chicken thighs out of the pot and place them in a bowl. Discard the bay leaf and Parmesan rind from the pot. Let the chicken cool for a few minutes until you can handle it. Remove and discard the skin and bones, then shred the meat with two forks into bite-size pieces.

Step 6: Cook the Pasta

While the chicken cools, bring the soup back to a gentle boil. Add the pasta directly to the pot and cook according to package directions until al dente, usually 7 to 9 minutes for small shapes. Stir often so the pasta does not stick to the bottom. If you cook the pasta separately, boil it in salted water in another pot, then drain and hold it aside.

Step 7: Finish the Soup

Return the shredded chicken to the pot and stir to combine. Lower the heat to low so the soup gently simmers. Stir in the lemon zest and lemon juice, then taste and adjust with more salt, pepper, or lemon as needed. Add fresh parsley and dill, and stir again.

Step 8: Add Greens or Extras

If you use spinach or kale, stir it into the hot soup and cook 2 to 3 minutes until it softens. Add frozen peas in the last 2 minutes of cooking so they stay bright and sweet. Sprinkle in crushed red pepper flakes if you like a little kick. Ladle the soup into bowls and top with extra herbs and grated Parmesan.

What to Serve with Italian Penicillin Soup Recipe

Serve this Italian Penicillin Soup Recipe with warm crusty bread, garlic bread, or simple toast brushed with olive oil. A crisp green salad with cucumbers, tomatoes, and a light vinaigrette balances the cozy richness of the broth. Kids usually love this soup with buttered noodles or simple crackers on the side. You can also pair it with sliced fruit, such as oranges or apples, for a fresh and soothing finish.

Storage Options

Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
Keep the pasta separate from the broth if possible, so it does not soak up all the liquid in the fridge.
Freeze the soup without pasta in freezer-safe containers or bags for up to 3 months, then add fresh pasta when you reheat.
Reheat gently on the stove over medium-low heat until hot, and add a splash of broth or water if it thickens too much.
Reheat single portions in the microwave in short bursts, stirring between each, and finish with a squeeze of fresh lemon and a sprinkle of herbs.
