Italian penicillin soup delivers comforting warmth through its silky golden broth, tiny pastina pasta, and tender shredded chicken. This one-pot recipe comes together in 40 minutes, blending vegetables for natural creaminess that soothes on sick days or chilly evenings.

What Makes Italian Penicillin Soup Special
Pastina soup traces its roots to Italian nonnas serving simple broths with tiny pasta to nourish the ill, earning the nickname “penicillin” for its restorative feel. Garlic, carrots, and herbs build immune-supporting flavors, while blending creates a porridge-like texture easy to enjoy when under the weather. Unlike chunky chicken noodle soup, this version offers smooth elegance with protein-packed bites.

Quick Swaps Table
| Variation | Key Changes | Why It Works |
|---|---|---|
| Vegan | Vegetable broth, 1 can chickpeas (drained) instead of chicken | Plant-based protein, same heartiness |
| Gluten-Free | Gluten-free pastina like Jovial brand | Inclusive for all diets |
| Spicy | Add 1/2 teaspoon red pepper flakes or chopped jalapeño | Clears sinuses instantly |
| Creamier | Stir in 1/4 cup coconut milk post-blend | Dairy-free richness |
Prep tip: Chop veggies roughly since they get blended. Total time: 40 minutes (10 prep, 30 cook).
Step-by-Step Instructions
Follow these numbered steps for foolproof results. An immersion blender simplifies blending right in the pot.
- Sauté Aromatics: Heat olive oil in a large Dutch oven or pot over medium heat. Add onion, carrots, celery, garlic, ginger (if using), salt, and pepper. Cook 5-7 minutes, stirring occasionally, until vegetables soften and edges brown lightly. This builds deep flavor.
- Simmer Broth: Pour in chicken broth, add Parmesan rind and thyme. Bring to a boil, then reduce to a gentle simmer. Cover partially and cook 20-25 minutes until veggies are very tender (fork pierces easily).
- Blend for Creaminess: Remove rind and herbs. Use an immersion blender to puree until smooth. (For standard blender: Transfer in batches, cool slightly, cover lid with towel to vent steam.) Reserve 1 cup puree if you prefer some texture; return to pot.
- Cook Pastina and Chicken: Bring soup back to a simmer. Stir in pastina and cook 7-9 minutes (check package), stirring to prevent sticking. Add shredded chicken to warm through, 2-3 minutes.
- Finish and Serve: Turn off heat. Stir in lemon juice. Taste and adjust salt or lemon. Ladle into bowls, topping with grated Parmesan, chopped parsley, black pepper, and a drizzle of olive oil.
Serve hot with crusty bread. Makes great leftovers; yields about 10 cups.
Expert Tips for the Best Soup
- Pasta Perfection: Cook pasta separately for leftovers to avoid mushiness. Store broth and pasta apart; combine when reheating.
- Broth Boost: Parmesan rind adds restaurant-level savoriness; freeze extras for future soups.
- Make-Ahead: Broth freezes up to 3 months. Thaw overnight, add fresh pasta.
- Scaling: Double for a crowd, but cook pasta in batches.
- Thicker or Thinner?: Blend more veggies for porridge-style; add broth for soupier consistency.
