Ingredients
The magic of this soup lies in the harmony of its components. Tiny pastina acts as the perfect vehicle for the broth, while a medley of mushrooms supplies the signature “penicillin” depth. Fresh herbs, aromatic vegetables, and a splash of white wine create layers of flavor that unfold with each spoonful.
Main Ingredients
- 150 g pastina (tiny star‑shaped pasta)
- 6 oz fresh porcini mushrooms, sliced
- 4 oz shiitake mushrooms, stems removed and sliced
Broth & Aromatics
- 4 cups low‑sodium chicken or vegetable broth
- ½ cup dry white wine (preferably Pinot Grigio)
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 2 tbsp extra‑virgin olive oil
Seasonings & Garnish
- ½ tsp dried thyme
- ¼ tsp freshly cracked black pepper
- Salt to taste
- 2 tbsp freshly chopped flat‑leaf parsley
- Optional: ¼ cup grated Parmigiano‑Reggiano
Each component plays a specific role: the broth provides a light, savory canvas; the wine adds acidity and depth; the mushrooms deliver the signature “penicillin” umami; and the pastina absorbs just enough liquid to stay tender without becoming mushy. Finishing with parsley and Parmesan adds a fresh, aromatic lift that rounds the soup beautifully.
Step-by-Step Instructions

Preparing the Aromatics
Begin by heating the olive oil in a large saucepan over medium heat. Add the diced onion and sauté for 3–4 minutes, stirring occasionally, until it becomes translucent and just starts to caramelize. This step builds a sweet foundation that balances the earthiness of the mushrooms later on.
Sautéing the Mushrooms
Add the sliced porcini and shiitake mushrooms to the pan. Increase the heat to medium‑high and cook for about 5 minutes, allowing the mushrooms to release their moisture and then brown slightly. Browning creates the “penicillin” flavor profile—rich, deep, and slightly nutty.
Deglazing & Building the Broth
- Deglaze with Wine. Pour the white wine into the pan, stirring to loosen any browned bits stuck to the bottom. Let it simmer for 1–2 minutes until the alcohol evaporates, leaving a subtle acidity that brightens the broth.
- Add Garlic and Herbs. Stir in the minced garlic, dried thyme, and black pepper. Cook for 30 seconds—just enough for the garlic to become fragrant without burning, which would add bitterness.
- Introduce the Broth. Pour in the chicken or vegetable broth, bring the mixture to a gentle boil, then reduce to a low simmer. Taste and season with salt; remember the broth may already contain some salt, so adjust gradually.
Cooking the Pastina
Once the broth is simmering, add the pastina. Stir gently and cook for 5–7 minutes, or until the pasta is al dente. Pastina cooks quickly, so keep an eye on it to prevent over‑cooking, which would turn the soup gummy.
Finishing Touches
Turn off the heat and stir in the chopped parsley. If you love a richer mouthfeel, fold in the optional grated Parmigiano‑Reggiano now; it will melt into the hot broth, adding a silky texture. Ladle the soup into bowls, drizzle a tiny drizzle of extra‑virgin olive oil if desired, and serve immediately while steaming.
Tips & Tricks
Perfecting the Recipe
Use Fresh Mushrooms. Fresh porcini and shiitake deliver the most intense umami; if you must use dried, rehydrate them in warm water and reserve the soaking liquid for extra flavor.
Don’t Over‑cook Pastina. Pastina continues to absorb broth after you remove it from heat, so pull the soup off the stove when the pasta is just shy of al dente.
Season in Layers. Add a pinch of salt after each major step—onions, mushrooms, and broth—to build depth without over‑salting.
Flavor Enhancements
A splash of fresh lemon juice just before serving adds bright acidity that lifts the earthy mushrooms. For a subtle heat, stir in a pinch of red‑pepper flakes. Finish with a drizzle of truffle oil for an indulgent, aromatic finish.
Common Mistakes to Avoid
Avoid adding the pastina too early; it will become mushy and thicken the broth excessively. Also, never dump the wine into a cold pan—this can cause the alcohol to evaporate too quickly, leaving a harsh flavor.
Pro Tips
Reserve Mushroom Soak. If using dried mushrooms, keep the soaking liquid, strain it, and substitute part of the broth with this intensely flavored stock.
Use a Heavy‑Bottomed Pot. Even heat distribution prevents scorching the broth and ensures the mushrooms brown evenly.
Finish with Cold Butter. A small knob of cold butter whisked in at the end creates a glossy, velvety finish without making the soup greasy.
Variations
Ingredient Swaps
Swap the porcini for cremini or button mushrooms for a milder taste, or replace pastina with orzo or small ditalini for a different texture. For a richer broth, substitute half of the chicken stock with half‑and‑half and add a splash of heavy cream at the end.
Dietary Adjustments
Use gluten‑free pasta such as rice or corn‑based mini shells to keep the dish gluten‑free. For a vegetarian version, choose vegetable broth and skip the chicken stock. Vegan diners can replace the Parmesan with nutritional yeast and use olive oil instead of butter.
Serving Suggestions
Serve the soup with a crisp Italian bread for dipping, or alongside a simple arugula salad dressed with lemon and olive oil. A side of roasted red peppers adds a sweet contrast, while a dollop of pesto can turn the bowl into a vibrant, herb‑forward feast.
Storage Info
Leftover Storage
Cool the soup to room temperature, then transfer it to an airtight container. Refrigerate for up to 3 days. If you plan to keep it longer, portion into freezer‑safe bags and freeze for up to 2 months; label with the date for best quality.
Reheating Instructions
Reheat gently on the stovetop over low heat, adding a splash of broth or water to restore the original consistency. Stir frequently to prevent the pasta from sticking. In a microwave, cover the bowl loosely and heat in 30‑second intervals, stirring between each, until hot throughout.
