Ingredients
6 cups hot rich meat broth (all chicken, all beef or a combination of the two; freshly made or canned)
2 ounces (1/8 of a 1-pound package) vermicelli
1/4 pound (1/2 cup) soft sweet (unsalted) butter
3/4 cup freshly grated parmesan cheese
4 egg yolks
1 cup heavy cream
Method
Bring the broth to a steady boil over direct heat on the stovetop or over a controlled flame if cooking at the table. Once the broth reaches a boil, add the vermicelli. If you prefer shorter noodles, break the vermicelli before adding. Cook uncovered for 5–8 minutes, or until the pasta is tender but still has a slight bite (al dente).
While the vermicelli cooks, prepare the creamy liaison: in a mixing bowl, combine the softened unsalted butter with the freshly grated parmesan cheese and the egg yolks. Beat these together until smooth and well incorporated. Gradually add the heavy cream in a steady stream while continuing to mix, forming a silky, homogeneous mixture.
To temper the egg and cream mixture and prevent curdling, spoon a small amount of the hot broth into the bowl—just enough to warm the mixture—while stirring constantly. Once the liaison is gently warmed, pour it slowly back into the pot of hot broth and noodles, stirring continuously to distribute the cream and eggs evenly through the soup.
After adding the liaison, remove the pot from the heat. If you are serving from a chafing dish, extinguish the flame so the residual heat finishes the cooking without scrambling the eggs. Stir gently and taste, adjusting seasoning if necessary—keep in mind the parmesan and broth both contribute salt, so add salt only if needed.
Ladle the finished soup into warmed bowls and serve immediately. This simple vermicelli soup is rich and comforting, with a silky texture from the butter, cream and eggs and a savory depth from the parmesan and meat broth.
Tips for Best Results
– Use high-quality broth: a flavorful homemade or low-sodium store-bought broth will yield the best taste. Mixing chicken and beef broths can create a more complex flavor profile.
– Grate the parmesan fresh rather than using pre-grated cheese for a cleaner melt and better flavor.
– Temper the egg-cream mixture slowly to avoid curdling. The key is gentle warming and continuous stirring.
– Cook the vermicelli to just tender. Overcooked pasta will become mushy when combined with the hot liaison.
– Keep the soup off high heat once the egg mixture is added; residual heat is enough to finish cooking without causing the eggs to scramble.
Variations and Serving Suggestions
This base recipe adapts well to simple variations: stir in a handful of chopped fresh herbs (such as parsley or chives) just before serving for brightness, or add a few shaved truffles or a drizzle of good olive oil for an elegant finish. For a heartier meal, serve the soup with crusty bread, garlic toast, or a light salad. You can also fold in cooked shredded chicken for added protein if using chicken broth.
Storage and Reheating
Store any leftover soup in an airtight container in the refrigerator for up to 2 days. Because the soup contains eggs and cream, gentle reheating is important: warm slowly over low heat, stirring frequently. If the noodles absorb too much liquid on standing, add a splash of broth or water while reheating to restore the desired consistency.
Notes
This recipe relies on simple, high-quality ingredients and careful temperature control to achieve a smooth, velvety texture. It’s designed to be made quickly while preserving the delicate balance between the creamy liaison and the savory broth. Enjoy this comforting vermicelli soup as a starter or a light, satisfying main course.
