Italian Penicillin Pastina Soup

Warm, silky pastina in rich chicken broth finished with egg and Parmesan — the ultimate quick comfort bowl for chilly nights.

Why You'll Love This Recipe
- Ready in under 20 minutes from start to finish — perfect for weeknight comfort when time is short.
- Uses pantry staples: pastina, chicken broth, an egg, butter, and Parmesan — most cooks already have these on hand.
- Highly comforting texture: small pasta cooks quickly and the egg creates a silky, almost creamy mouthfeel without heavy cream.
- Scales easily: double or triple the batch for a family or to freeze individual portions for later.
- Make-ahead friendly: broth can be prepared in advance and the soup comes together in minutes when reheated.
- Dietary flexibility: swap to vegetable broth or use a vegan Parmesan alternative to suit dietary needs.
In my house this is the soup that sparks the most gratitude. My partner calls it “instant sunshine” and my grandmother praised the simplicity — she said it reminded her of the kind of soup she made when her children were young. Over the years I’ve learned small adjustments: stirring constantly while adding the egg prevents curdling, and using a microplane for the cheese gives the best melt and flavor distribution.
Ingredients
- Chicken broth (4 cups): Choose a high-quality low-sodium broth or homemade stock for the most depth. I prefer a store-bought broth like Pacific Foods or Swanson low-sodium when I'm short on time; homemade gives the best body and a richer mouthfeel.
- Pastina (1 cup): Tiny star or pastina shapes work best because they cook quickly and hold the silky broth. Look for traditional Italian pastina or any small, quick-cooking pasta like orzo or acini di pepe if you prefer a slightly different texture.
- Egg (1, beaten): Adds protein and creates a silken finish when whisked in slowly. Use a large, room-temperature egg so it incorporates smoothly without seizing up the broth.
- Parmesan cheese (1/4 cup freshly grated): Use real Parmigiano-Reggiano if possible; its salty, nutty profile elevates the soup. Freshly grating yields a lighter, more even melt than pre-grated varieties.
- Butter (1 tablespoon): Adds richness and sheen — unsalted butter lets you control seasoning more precisely.
- Salt & black pepper: Season to taste. Because broth and Parmesan contribute salt, taste before adding more. Freshly cracked black pepper adds a pleasant finish.
Instructions
Bring the broth to a gentle boil: Pour 4 cups of chicken broth into a medium saucepan and bring it to a gentle rolling boil over medium-high heat. Use a lid to speed the process if desired, but remove it as soon as the liquid reaches a simmer to avoid over-evaporation. The goal is an active simmer, not an aggressive boil, to cook the pasta evenly. Cook the pastina: Add 1 cup of pastina to the boiling broth, stir to separate, then reduce heat to maintain a gentle simmer. Cook for 6 to 8 minutes, stirring occasionally, until the tiny pasta is al dente — tender with a slight bite. Timing varies slightly by brand; taste at 6 minutes to check doneness. Keep an eye on the pot so the pasta doesn’t stick or swell excessively. Temper and add the egg: Reduce heat to low so the broth is just above a simmer. Beat 1 large egg in a small bowl until smooth. Slowly drizzle the beaten egg into the pot while continuously whisking the soup to create thin, silky ribbons rather than scrambled clumps. The constant motion and low heat are key to a velvety texture — work steadily and don’t pour too fast. Finish with butter and cheese: Once the egg is fully incorporated, stir in 1 tablespoon of butter and 1/4 cup freshly grated Parmesan until melted and integrated. Taste and adjust with salt and freshly ground black pepper. The butter adds silk and the Parmesan brings a savory lift that makes each spoonful feel complete. Serve warm: Ladle the soup into warmed bowls and garnish with extra Parmesan and a light grind of black pepper. Serve immediately while the texture is at its peak; the pasta will continue to soften if left standing.
You Must Know
- This dish is high in protein for its size due to the egg and broth — a light, nourishing bowl at about 190 calories per serving.
- Leftovers refrigerate well for 2 days; the pasta will absorb liquid and soften, so add extra warm broth or water when reheating.
- Freezes best as broth only; cooked pastina gets mushy when frozen then thawed. Freeze portioned broth for up to 3 months.
- Use low-sodium broth if reducing salt for dietary needs and always adjust seasoning after adding cheese.
What I love most is how forgiving this preparation is — small technique changes, like tempering the egg slowly, make a big difference, but the soup retains its soul even when made hastily. My sister prefers a little lemon zest at the end for brightness, while my father sprinkles chopped fresh parsley. No matter the tweak, the core comfort remains: warm, simple, and soothing.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 48 hours. The pastina will continue to absorb broth, so when reheating, add 1/2 cup of warm chicken broth or water per bowl to restore the original soup consistency. Reheat gently on the stovetop over low heat while stirring to reincorporate the egg and cheese. Do not freeze the fully assembled soup; freeze plain broth in individual portions for up to 3 months and cook fresh pastina when ready to serve for the best texture.
Ingredient Substitutions
If you want to adapt for dietary needs, use vegetable broth instead of chicken broth for a vegetarian version and a vegan Parmesan alternative plus a vegan butter substitute to keep the silky finish. Swap pastina with orzo or small ditalini if unavailable — reduce cooking time slightly for orzo. To increase protein, stir in shredded rotisserie chicken after the pasta is cooked. For lower sodium, select a low-sodium broth and skip adding extra salt until after tasting with the Parmesan.
Serving Suggestions
Serve this bowl as a light lunch or starter alongside a crisp green salad and crusty bread like a sliced baguette or focaccia to mop up the broth. For a more substantial meal, pair with roasted vegetables or add cooked shredded chicken and a handful of baby spinach stirred in at the end. Garnish with fresh herbs such as parsley or chives and a light drizzle of extra-virgin olive oil for shine and aroma.
Cultural Background
Pastina is a staple in many Italian households, especially as a comfort food for children and the sick. The name literally means "tiny pasta," and its diminutive size makes it perfect for soothing broths and simple, nourishing preparations. In Italy, small shapes like stelline (stars) or pastine are often cooked in meat or vegetable broths and lightly enriched with cheese or butter — a tradition rooted in making the most of simple ingredients to provide warmth and nourishment.
Seasonal Adaptations
In winter, enhance the depth by using homemade chicken stock and add a few roasted garlic cloves for an aromatic lift. In spring, finish with a squeeze of lemon and a sprinkle of fresh herbs for brightness. For autumn, stir in a spoonful of pureed roasted squash for a subtly sweet, velvety variation. These small seasonal shifts keep the base recipe fresh year-round while honoring the soup’s inherent simplicity.
Meal Prep Tips
Prepare the broth in advance and store it in Mason jars in the fridge for up to 4 days. Measure out pastina into portioned bags so you can drop it straight into simmering broth. If making multiple servings for the week, cook pasta fresh each time — it takes under 10 minutes and preserves the ideal texture. Pack dry pastina, a small container of grated Parmesan, and a single egg for a portable option if you have a way to heat the broth at work.
This simple bowl is one of those timeless recipes that always feels like a warm hug. Whether you’re tending to a sick family member, feeding picky eaters, or craving a quick, satisfying meal, this pastina preparation delivers comfort with minimal fuss. Share a bowl and it will quickly become part of your own kitchen traditions.
Pro Tips
Temper the beaten egg by whisking continuously while drizzling it into the warm broth to avoid curdling.
Use low-sodium or homemade broth to control salt level since Parmesan adds saltiness.
Warm bowls before serving to keep the soup hot longer and enhance the experience.
If reheating leftovers, add warm broth to restore texture since pastina absorbs liquid.
Freshly grate Parmesan for the best melt and flavor — pre-grated cheese contains anti-caking agents that hinder melting.
This nourishing italian penicillin pastina soup recipe is sure to be a staple in your kitchen. Enjoy every moist, high protein slice — it is perfect for breakfast or as a wholesome snack any time.
