Italian Stracciatella Soup | Zuppa di Stracciatella
Stracciatella is a Roman soup with three working parts and nowhere to hide. A clear meat broth, eggs beaten with grated Parmigiano Reggiano, and a grating of nutmeg. The egg goes into the broth in a thin stream and sets on contact into soft irregular threads, and those threads are what give the soup its name: stracciatella means little rags.
Everything depends on the broth. It has to be genuinely good, because nothing in the bowl covers for a weak one, and it has to be at the right temperature when the egg arrives. Too hot and the egg seizes into hard grains that sink like scrambled egg. Too cool and it disperses into cloud and never forms threads at all. The window is narrower than most recipes admit.
It is a soup of the Roman table on ordinary days and of Christmas and Easter lunches, when it is made with the broth from a boiled capon or a piece of beef. It takes about eight minutes once the broth is hot, which is why it survives in households that no longer cook anything else from scratch.

The Story
Stracciatella alla romana belongs to the family of Italian soups built on nothing but broth and egg, and it is the one that survived best. Its relatives are all over the peninsula, and the idea descends from the medieval practice of enriching a thin broth with beaten egg to make it feed more people. What Rome added was Parmigiano Reggiano in the egg mixture, which changes the physics as much as the flavour, and the nutmeg that marks so much of Lazio cooking.
The soup is tied to the Roman habit of the bollito, the pot of meat simmered for hours to produce both a second course and the broth that precedes it. On the days when a capon or a piece of beef brisket went into the pot, the broth that came out of it was far too good to be wasted, and stracciatella was the standard way to serve it. That connection explains why the soup appears at Christmas and Easter lunches in Roman households more reliably than at any other point in the year.
There is also a Roman tradition of serving it before a heavy secondo, and of giving it to anyone recovering from illness. Two very different roles for the same bowl, and they explain the restraint of the recipe: nothing is added that would make it rich. The fat that is there comes from the cheese and from whatever the broth carries, and a good stracciatella tastes clean rather than heavy.
Ingredients
For the broth
Chicken or capon carcass with wings, 2 1/2 lb (1.1 kg)
Beef shin or brisket, optional, 8 oz (225 g)
Cold water, 3 quarts (2.8 L)
Yellow onion, halved and left unpeeled, 1 large
Carrot, 1 large
Celery stalk with leaves, 1
Flat leaf parsley stems, 6
Black peppercorns, 8
Coarse sea salt, 1 tsp (6 g), plus more to adjust
For the stracciatella
Clear broth, strained and degreased, 6 cups (1.4 L)
Eggs, large, 4
Parmigiano Reggiano, finely grated, 1/2 cup (45 g)
Fine sea salt, 1/4 tsp (1.5 g)
Freshly grated nutmeg, 1/8 tsp
Freshly ground black pepper, to taste
For finishing
Parmigiano Reggiano, finely grated, 2 tbsp (12 g)
Flat leaf parsley, very finely chopped, 2 tsp
Extra virgin olive oil, a few drops per bowl
Finely grated lemon zest, optional, from 1/4 lemon
Preparation
Step 1
Start the broth cold. Put the chicken carcass and the beef, if you are using it, in a tall pot and cover with the cold water. Cold is not a detail: it draws soluble protein out slowly and lets it coagulate into grey scum you can lift off, while starting hot traps it inside and clouds the broth. Bring it very slowly to the point where the surface barely trembles and skim carefully for the first 15 minutes.
Step 2
Add the vegetables and hold the simmer. Once the surface is clean, add the onion, carrot, celery, parsley stems, peppercorns and the teaspoon of salt. From here the pot must never boil: one lazy bubble every few seconds and no more, for 2 1/2 to 3 hours. A boiling stock emulsifies its own fat and turns permanently murky, and straining does not bring it back. Do not cover the pot and do not stir it.
Step 3
Strain and degrease. Ladle the broth through a fine mesh sieve lined with damp muslin rather than pouring the pot, which disturbs the sediment and carries it through. Let it settle for 10 minutes and skim the fat with a wide spoon, or chill it and lift the fat off as a solid cap. It should be almost fatless, because floating fat prevents clean threads. Correct the salt now, while the broth stands alone.
Step 4
Mix the eggs and cheese. Beat the eggs with a fork, not a whisk, until the yolks and whites are combined but not aerated. Add the grated Parmigiano, the salt, the nutmeg and a grind of pepper and stir until the cheese is suspended with no clumps. The mixture should pour in a steady thread; if it looks stiff, loosen it with 2 tablespoons of cold broth. Let it sit 5 minutes so the cheese hydrates, then stir once more.
Step 5
Bring the broth to the right temperature. Heat the strained broth to a bare simmer and then pull it back so the surface is still and steaming, around 185°F (85°C). This is the single control point of the recipe. A rolling boil tears the egg into hard grains; broth below about 170°F (77°C) lets it dissolve into cloud. If you have a thermometer, use it once and remember what that surface looks like.
Step 6
Add the egg mixture. Stir the broth into a slow steady rotation with a fork held in your other hand, then pour the egg mixture in a thin stream over the tines of the fork, moving it around the pan. The fork breaks the stream and spreads it. Keep stirring gently for 15 to 20 seconds while the threads form. They should appear almost at once as soft irregular rags, pale yellow, suspended through the broth rather than sunk to the bottom.
Step 7
Stop and rest. Take the pan off the heat the moment the threads are set and let it stand 1 minute. The residual heat finishes the egg and the rags soften and distribute themselves through the liquid. Do not stir vigorously now or the threads break into fragments. Taste and adjust the salt, remembering the cheese has already added some.
Plating
Use warmed wide soup plates rather than deep bowls. The soup is shallow by nature and a wide plate shows the threads suspended in the broth, which is the whole visual interest of the dish. Warm the plates in a low oven, because a cold plate drops the temperature of a thin broth immediately and the soup arrives tepid.
Ladle from the middle of the pan rather than the surface or the bottom, so each portion gets an even share of the rags and of the clear liquid between them. Fill to about two thirds, never to the rim. Finish with a light grating of Parmigiano, a very small amount of chopped parsley and a few drops of good olive oil, which sits on the surface and carries aroma without making the soup greasy.
A little grated lemon zest is a modern addition and an optional one, but it lifts a broth that has simmered for three hours and stops the nutmeg dominating. Serve immediately with a slice of good bread, unbuttered. Nothing else belongs in the bowl.
Professional Technique
The entire dish turns on controlled egg coagulation. Egg white begins to set around 145°F (63°C) and yolk around 158°F (70°C), and both are fully firm well before boiling point. Pouring beaten egg into broth at 185°F (85°C) sets it in under a second, fast enough to hold a shape but slow enough that the strand stays tender. At a rolling boil the proteins contract violently and squeeze out water, which is what produces the tight grainy bits you get in a badly made version. The grated Parmigiano works as insurance here: its own protein and fat raise the temperature at which the egg mixture tightens and give the threads a softer, more forgiving set.
The second technique is clarification by restraint rather than by raft. A classic consommé is cleared with egg white, but a Roman kitchen simply never lets the pot boil. Broth turns cloudy for two reasons, emulsified fat and suspended protein particles, and both are driven by agitation. Holding the pot at a bare simmer, skimming early and hard, straining through muslin and degreasing thoroughly gets you a broth clear enough for this soup without any clarification step at all.
Texture and Moisture Control
There are only two textures in the bowl and both are fragile. The broth must stay thin and clear, with no thickening whatsoever: stracciatella is not an egg drop soup thickened with starch, and adding flour or cornflour turns it into something else. The rags must be soft and slightly ragged at the edges, holding together when the spoon lifts them but yielding immediately. Anything firmer means the broth was too hot; anything that has dissolved means it was too cool.
The cheese is a texture ingredient as much as a flavour one. Grated finely on a rasp it disperses through the egg and stays suspended; grated coarsely it clumps and sinks, taking egg with it and leaving heavy lumps at the bottom of the pan. Use Parmigiano Reggiano with real age on it, and grate it at the last moment, because pre grated cheese carries anticaking starch that clouds the broth.
Fat control decides whether the surface looks clean or greasy. A broth that has not been degreased properly shows a slick that coats the palate and dulls the nutmeg, and it also interferes with thread formation by coating the egg as it enters. Chilling the broth overnight and lifting the solid cap off is by far the most reliable method, and it costs nothing but planning.
Professional Mise en Place
The broth is the long job and it is entirely separable from the service. Once it exists, the soup is eight minutes of work, so plan around the broth and keep the final stage uninterrupted.

Chef Tips
Make the broth with a capon carcass if you can get one, especially around Christmas. Capon gives more body and a rounder flavour than chicken, from its higher fat and collagen, and it is the traditional base in Roman households. Failing that, chicken wings with a piece of beef shin give depth that chicken alone does not.
Pour the egg mixture over the back of a fork rather than straight from the bowl. The tines split the stream into several thinner ones, each of which sets independently, and that is what produces fine rags instead of a few thick ribbons. It is the oldest trick in the recipe and the one most often left out of written versions.
Grate the nutmeg fresh and use less than you think. Ground nutmeg from a jar is flat and dusty, while the whole nut keeps its oils for years. An eighth of a teaspoon is enough to be present without announcing itself, sitting behind the cheese rather than in front of it.
If you have to use shop bought stock, buy a fresh one from a butcher rather than a carton and taste it first. Most cartons are heavily salted and thin, and the cheese will push a salty broth over the edge. Dilute if necessary and correct the seasoning only after the cheese has gone in.
Common Mistakes
Adding the egg to boiling broth. This is the failure that ruins most versions. A rolling boil sets the egg instantly into hard grains that sink, giving scrambled egg in soup rather than stracciatella. Pull the pan back until the surface is still and steaming first.
Letting the broth boil while it simmers. A boiling stock emulsifies its own fat and turns cloudy for good. One lazy bubble every few seconds is the correct pace for the full three hours, and a broth that has boiled cannot be cleared.
Whisking the eggs until frothy. Air beaten into the egg makes the rags puffy and spongy rather than soft and fine, and the foam disperses into the broth as scum. Beat with a fork only until the yolk and white are combined, and stop.
Stirring hard after the egg goes in. Vigorous stirring shreds the threads into fragments and clouds the broth with them. Keep the rotation slow and gentle for 15 to 20 seconds, then stop moving the spoon altogether.
Skipping the degreasing. Fat floating on the broth coats the egg as it enters, prevents clean threads and leaves a slick that flattens the nutmeg. Chill the broth and lift the cap off, or skim patiently with a wide spoon.
Using pre grated cheese. The anticaking agents in bagged Parmigiano cloud the broth and refuse to dissolve into the egg, leaving gritty specks. Grate a piece of real Parmigiano Reggiano on a fine rasp at the moment you need it.
Wine Pairing
Frascati Superiore DOCG: The Roman answer, from the volcanic hills outside the city, and the bottle this soup grew up beside. A dry Superiore has more substance than basic Frascati and a soft almond and white flower character that sits against nutmeg and aged cheese. Its acidity is moderate rather than sharp, which matters, because a high acid white would cut straight through a delicate broth.
Orvieto Classico DOC: A short distance north in Umbria and built on the same volcanic logic. The Grechetto and Procanico blend gives a faintly waxy texture and a quiet bitter finish that echoes the Parmigiano without competing. Its low aromatic intensity is exactly what a bowl of broth and egg needs beside it.
Verdicchio di Matelica DOC: The inland Verdicchio, grown in a cool valley that gives it more tension and a firmer mineral line than the Jesi version. It has the structure to stand up to the cheese and the residual richness of a capon broth, while its bitter almond finish runs alongside the nutmeg. Serve it around 50°F (10°C) so the texture stays broad.
Cesanese del Piglio DOCG: The red option, and a genuinely Roman one from the hills southeast of the city. Cesanese is light in tannin, faintly peppery and floral, and served cool at around 57°F (14°C) it works with the broth rather than crushing it. Choose this when the stracciatella precedes a bollito or a roast rather than standing alone.
Lugana DOC: A northern alternative for anyone who wants more weight in the glass. Turbiana from the southern shore of Lake Garda has a saline edge and a slightly oily texture that matches the fat a good broth carries, with enough body for the cheese and enough freshness to keep the bowl light.
Storage & Reheating
The finished soup is a poor keeper and should be made to order. The broth is the opposite: it keeps refrigerated in a sealed container for 3 days and freezes for up to 3 months, and it improves in the refrigerator overnight because the fat sets into a cap you can lift off cleanly. Freeze it in portions of 6 cups (1.4 L), which is exactly what this recipe needs, and label it with the date.
If you do have leftover stracciatella, refrigerate it for no more than 1 day and reheat it very gently in a saucepan over low heat, stopping the moment it steams. Never boil it and never microwave it, both of which toughen the egg threads into rubber and cloud the broth. The rags will always be slightly firmer the second day, and no technique recovers the original texture.
Do not freeze the assembled soup. Egg protein that has been frozen and thawed turns spongy and weeps water, and the clear broth becomes grey and grainy. Freeze the broth alone, thaw it overnight in the refrigerator, and make the stracciatella fresh in the eight minutes it takes.
