Your Grocery List
Here’s everything you need to bring this cozy bowl of goodness to life:
- 8 cups of chicken broth (homemade if you can, but store-bought works too!)
- 1 cup of pastina (or substitute with orzo or mini shells if you can’t find it)
- 2 large eggs
- 1/2 cup grated Parmesan cheese (plus more for topping!)
- Salt and freshly ground black pepper, to taste
- 1 tablespoon of butter (optional, but adds that extra creamy touch!)
- Fresh parsley, chopped (for garnish, if you’re feeling fancy!)
Choosing the Perfect Pastina for Your Soup
Pastina means “little pasta” in Italian, and it comes in the cutest shapes—stars (stelline), tiny balls (acini di pepe), or even alphabet letters. If you can’t find pastina at your local store, don’t worry. Orzo, ditalini, or even mini shells will work beautifully. The key is using a small pasta that cooks quickly and gives you that cozy, spoonful-of-comfort vibe.
Techniques and Tips for the Coziest Bowl
Here’s where the magic happens: whisking the eggs into the hot broth creates those silky, comforting ribbons that make this soup so special. The key is to temper the eggs by whisking a little hot broth into them first—this prevents them from scrambling and gives you that smooth, dreamy texture. And don’t skimp on the Parmesan—it adds that rich, savory depth that makes every bite feel like it’s hitting the spot.
Make It Even Better
Want to take your Italian Penicillin Soup to the next level? Stir in a little butter at the end for a creamier finish, or add shredded rotisserie chicken if you’re craving something heartier. You can even toss in some spinach or peas for extra nutrients—perfect when you’re trying to sneak in some veggies for the kiddos! Leftovers? They reheat like a dream. Just add a splash of broth to loosen things up, and you’re good to go.
What to Serve with Italian Penicillin Soup
This soup pairs perfectly with a slice of crusty Italian bread or a simple green salad. If you’re in the mood for a full Italian feast, serve it alongside a classic Margherita pizza or a glass of crisp white wine. And don’t forget dessert—a creamy tiramisu or a simple biscotti will round out the meal beautifully.
How to Store Leftovers
Got leftovers? Lucky you! Store the soup in an airtight container in the fridge for up to 3 days. The pasta will soak up some of the broth, so when you reheat it, just add a splash of chicken stock to bring it back to life. It’s just as comforting the next day—if not more!
