Vegan Roman Cacio e Pepe Spaghetti, Reinterpreted | Spaghetti Cacio e Pepe Vegani Rivisitati
Cacio e pepe is the most minimal of the great Roman pastas: in its classic form, spaghetti, Pecorino Romano, black pepper and the starchy water the pasta cooked in, whisked into a cream that clings to every strand. The Roman original is made only with Pecorino Romano, black pepper, pasta and water; this vegan version is a reinterpretation of it, not the classic recipe. It keeps the Roman method intact and replaces only the cheese, with a fine cream of soaked cashews, nutritional yeast, a few drops of lemon and sea salt, and the same starchy cooking water. The pepper is toasted in a dry pan and bloomed in that water, exactly as Roman cooks do, so its heat and aroma carry the dish. The result is glossy, peppery, savory and fluid, a plate that tastes of Rome without a single animal ingredient.

The Story
Cacio e pepe comes from the countryside of Lazio and from the shepherds who moved their flocks between the Roman plain and the Apennine pastures. Tradition says that they carried dried pasta, a wheel of Pecorino and black pepper, three foods that kept for weeks without spoiling and that could be turned into a hot meal with nothing but water and a fire. The word cacio is the old central Italian name for cheese, and the dish says exactly what it is: cheese and pepper. It is a dish of the poor and of the road, and it reached the trattorie of Rome as a classic of the city's table.
The original is not vegan: its soul is Pecorino Romano DOP, the hard, salty sheep's milk cheese of Lazio, grated finely and melted into a cream with the hot pasta water. That cheese gives three things at once: salt, savory depth and the proteins and fat that form a stable emulsion. This reinterpretation changes only the cheese, so it must replace all three honestly. Here the fat and the body come from cashews soaked and blended until completely smooth, the savory depth from nutritional yeast, an inactive yeast rich in glutamates, and the salt from fine sea salt measured with care. A few drops of lemon recall the light tang of the original Pecorino Romano.
Black pepper is the other half of the name. Pepper reached Rome from India in antiquity and was so prized that the Romans traded it at enormous prices; Apicius, the collection of Roman recipes that has come down to us, uses it in a great many of its recipes. In cacio e pepe the pepper is not a seasoning added at the end but a main ingredient, crushed coarsely and toasted so that its essential oils open and its heat becomes round rather than sharp.
Cacio e pepe belongs to the family of Roman pastas built on the same base, with gricia, amatriciana and carbonara as its relatives. It is also famously difficult: the cheese clumps if the water is too hot, and the sauce breaks if it is too thin. The cashew cream is more forgiving than cheese, but the method stays the same. This recipe keeps the Roman gesture, the pepper bloomed in pasta water and the pasta finished in the pan, and adds precision on the soaking, the starch concentration and the temperature of the emulsion.
Ingredients
Use bronze-extruded spaghetti or tonnarelli-style square spaghetti made only of durum wheat semolina and water: their rough surface releases more starch, and starch is what holds this sauce together. Buy raw, unsalted cashews, never roasted, because roasted nuts give a brown color and a toasted taste that do not belong here. Choose whole black peppercorns, fresh and aromatic, from a shop with high turnover; pre-ground pepper has already lost most of its perfume. Nutritional yeast should be in flakes, pale yellow and fresh smelling.
For the cashew cream
Raw cashews, unsalted, 1 cup (140 g)
Cold water, for soaking, 3 cups (710 ml)
Nutritional yeast flakes, 3 tbsp (12 g)
Fresh lemon juice, 1 tsp (5 ml)
Fine sea salt, 3/4 tsp (4 g)
Garlic, 1 small clove, peeled, optional
Cold water, for blending, 2/3 cup (160 ml)
For the pepper and the pasta
Whole black peppercorns, 1 tbsp (7 g)
Spaghetti, bronze extruded, 12 oz (340 g)
Water, for cooking the pasta, 2 1/2 quarts (2.4 l)
Coarse sea salt, for the pasta water, 1 tbsp (15 g)
Extra virgin olive oil, mild, 2 tbsp (30 ml)
For the finish
Black peppercorns, freshly cracked, 1 tsp (2 g)
Toasted cashew crumble, 2 tbsp (15 g), finely chopped
Nutritional yeast flakes, 1 tsp (2 g)
Extra virgin olive oil, peppery, 1 tbsp (15 ml)
Preparation
Step 1
Soak the cashews. Rinse the cashews and cover them with 3 cups (710 ml) of cold water. Leave them for at least 4 hours at room temperature, or up to 12 hours in the refrigerator. For a quicker method, cover them with boiling water and leave them for 30 minutes. Soaking softens the cell walls of the nut and hydrates its starch and proteins, so the cashews blend into a completely smooth cream with no grain on the tongue. Drain them and rinse them again, because the soaking water carries a slightly bitter taste.
Step 2
Blend the cashew cream. Put the soaked cashews in a high-speed blender with the nutritional yeast, lemon juice, fine salt, the garlic if you use it and 2/3 cup (160 ml) of cold water. Blend for 2 to 3 minutes, stopping to scrape the sides, until the cream is perfectly smooth, thick and pourable, like heavy yogurt. Rub a drop between your fingers: it must feel silky, never sandy. Keep it at room temperature. A cold cream would drop the temperature of the pan too far and make the sauce set before it coats the pasta.
Step 3
Toast the pepper. Crush the peppercorns coarsely in a mortar, so you have a mix of halves, quarters and fine powder. Put them in a wide, heavy skillet over medium heat, without oil, and toast them for 60 to 90 seconds, shaking the pan, until they release a strong, warm aroma and the first wisp of smoke appears. Take the pan off the heat at once. Toasting releases the volatile oils of the pepper and softens its sharp edge into a rounder heat; the mix of sizes gives both an even warmth and small bursts of spice.
Step 4
Cook the spaghetti in less water. Bring 2 1/2 quarts (2.4 l) of water to a boil in a wide pot, add the coarse salt and the spaghetti, and stir during the first minute so the strands do not stick. The quantity of water is smaller than usual on purpose: the pasta releases the same amount of starch into less water, and a cloudy, starchy water is the base of the emulsion. Cook the spaghetti for 2 minutes less than the time on the package. They will finish cooking in the pan.
Step 5
Bloom the pepper in pasta water. About 4 minutes before the pasta is ready, return the skillet with the toasted pepper to medium heat, add the olive oil and 1 cup (240 ml) of the starchy pasta water, and let it simmer for 1 to 2 minutes. The water turns gray and fragrant as it takes the aroma of the pepper, and it reduces slightly. Take 1/2 cup (120 ml) of this peppery water and whisk it into the cashew cream until the cream is fluid and glossy, like single cream. This tempering step warms the cream gently so it blends into the pan without shock.
Step 6
Finish the pasta in the pan. Lift the spaghetti with tongs straight into the skillet with the peppery water, keeping another cup of pasta water aside. Toss and stir over medium heat for 1 to 2 minutes, adding a splash of pasta water whenever the pan looks dry, until the spaghetti are al dente and the liquid has reduced to a thin, cloudy film that coats them. This is the Roman risottatura of pasta: the spaghetti absorb peppery water and release more starch, and the starch prepares the surface for the sauce.
Step 7
Emulsify off the heat. Take the skillet off the heat and wait 30 seconds, so the temperature falls to about 175°F (80°C). Pour in the tempered cashew cream and toss the spaghetti vigorously with tongs, lifting and turning them, for 30 to 45 seconds. The cream, the starch and the oil come together into a glossy sauce that flows around the strands. If it is too thick, add pasta water a spoon at a time; if it is too loose, return the pan to the lowest heat for a few seconds while tossing. Taste for salt. The sauce should be creamy and fluid, never sticky, and should pool slightly at the bottom of the pan.
Plating
Serve at once in warm, shallow bowls heated to about 140°F (60°C), because this sauce, like the original, thickens within a minute as it cools. Twist each portion into a tight nest with a carving fork inside a ladle, and set it in the center of the bowl. Spoon over the sauce left in the pan, so the nest shines.
Finish each portion with a fresh grind of cracked black pepper, a light dusting of nutritional yeast, a pinch of the toasted cashew crumble for texture and a few drops of peppery olive oil. The guest eats it with a fork alone, as in Rome, and each forkful should carry a thin, even coat of cream with the warmth of pepper arriving first.
Professional Technique
The key ratio is starch to fat. For 12 oz (340 g) of spaghetti, the dish needs about 1 cup (240 ml) of cashew cream, 1/2 cup (120 ml) of peppery water to temper it and about 1 cup (240 ml) of starchy water used during the finish in the pan. Cooking the pasta in only 2 1/2 quarts (2.4 l) of water doubles the starch concentration compared with a large pot, and that starch is what binds the cashew fat and the water into a stable, glossy sauce.
The hidden variable is temperature. Cashew cream thickens fast when it boils: its starches swell and its proteins tighten, and the sauce turns pasty and dull. Off the heat, at about 175°F (80°C), it stays fluid and silky. That is why the cream goes in only after the pan has rested for 30 seconds, and why it is tempered first with warm pepper water instead of being added cold.
The doneness test is visual. Lift a strand with the fork: the sauce must coat it in a thin, continuous veil, without lumps and without a pool of thin water beneath. At the bottom of the bowl there should be only a spoonful of cream, glossy and pale, flecked with pepper.
Emulsion Control
An emulsion is a mixture of fat and water that would normally separate, held together by molecules that bind both. In the Roman original, the cheese proteins and the pasta starch do this work. In this vegan version, the cashew proteins and starches, together with the pasta starch, take their place. Vigorous tossing is not decoration: it breaks the fat into tiny droplets and spreads them through the water, which is what makes the sauce opaque and creamy.
Salt must be controlled at three points. The pasta water is salted lightly, because it reduces in the pan and part of it goes into the sauce. The cashew cream is salted moderately. The final taste is made only at the end, after the emulsion, when the reduction has concentrated everything. Nutritional yeast also brings some savoriness, so add it with judgment.
Timing decides the texture on the plate. From the moment the sauce comes together, you have about a minute before it begins to tighten. Have the bowls warm and the pepper mill ready before the pasta leaves the pot. If the sauce tightens in the bowl, a spoon of hot pasta water stirred in at the table brings it back.
Professional Mise en Place
The cashew cream can be made a day ahead and kept in the refrigerator; bring it back to room temperature before service. The rest of the dish takes 15 minutes and must be cooked at the last moment.

Chef Tips
Save more pasta water than you think you need. Before draining, take 2 cups (475 ml) of it in a mug. It is the only tool that corrects the sauce in the last minute, both when it is too thick and when it needs more gloss.
Toast the pepper just before cooking and never in advance. Its aroma fades within an hour of toasting, and the whole character of the dish depends on that first burst of perfume when the pepper meets the hot water.
If you want an even creamier sauce, replace 1/4 cup (35 g) of the cashews with the same weight of blanched almonds. Almonds give a slightly lighter, sweeter cream and a whiter color, while the cashews keep the body.
Cook at most two or three portions in one pan. A crowded skillet cools down and cannot be tossed properly, and the emulsion never forms evenly. For more guests, use two pans side by side.
Common Mistakes
Using roasted or salted cashews. Roasted cashews color the sauce beige and taste of toast, and salted ones make it impossible to control the seasoning. Use raw, unsalted cashews only.
Not blending long enough. A cream blended for 30 seconds stays grainy, and the grain shows on every strand. Blend for 2 to 3 minutes, until it feels like silk between the fingers.
Cooking the pasta in too much water. A large pot dilutes the starch, and the sauce turns thin and watery. Use about 2 1/2 quarts (2.4 l) of water for 12 oz (340 g) of spaghetti.
Using pre-ground pepper. Pepper ground long ago smells of dust, and the dish loses its point. Crush whole peppercorns and toast them just before cooking.
Adding the cream over high heat. Boiling cashew cream turns pasty and dull. Take the pan off the heat, wait 30 seconds, then add the tempered cream.
Draining the pasta in a colander. All the starchy water is lost, and the sauce has nothing to bind with. Lift the spaghetti with tongs straight into the pan.
Letting the plate wait. The sauce tightens within a minute. Have everything ready and serve at once in warm bowls.
Wine Pairing
Frascati Superiore DOCG: The white of the Castelli Romani, just south of Rome, from Malvasia and Trebbiano on volcanic soils. Its fresh acidity and soft almond note echo the cashew cream and clean the palate after each peppery forkful. Serve it at about 50°F (10°C).
Cesanese del Piglio DOCG: The red of the Ciociaria hills in southern Lazio, with red cherry, a light spice and gentle tannins. Its peppery notes meet the black pepper of the dish, and its moderate body does not overwhelm a simple plate. Serve it slightly cool, at about 60°F (16°C).
Orvieto Classico DOC: From the border of Umbria and upper Lazio, a white based on Grechetto and Trebbiano with pear, white flowers and a slightly bitter finish. Its clean line refreshes the palate against the creamy sauce. Serve it at about 50°F (10°C).
Verdicchio dei Castelli di Jesi Classico Riserva DOCG: A structured white of the Marche with almond, citrus and a savory, mineral finish. Its body stands up to the richness of the cashew cream, and its acidity keeps the dish lively. Serve it at about 52°F (11°C).
Storage & Reheating
Refrigerator: cacio e pepe is a dish to eat at once. Leftovers keep for 1 day in an airtight container, but the sauce sets around the pasta and loses its gloss. The cashew cream on its own keeps for 3 days in a closed jar in the refrigerator. Freezer: the cashew cream freezes well for up to 2 months; thaw it in the refrigerator and blend it for a few seconds before use. The finished pasta does not freeze well, because the spaghetti turn soft and the sauce separates.
Reheat leftovers in a skillet over low heat with 3 to 4 tbsp (45 to 60 ml) of hot water per portion, tossing constantly with tongs for 2 to 3 minutes until the sauce becomes creamy again. Avoid the microwave, which heats unevenly and makes the sauce grainy. Finish with fresh pepper and a few drops of olive oil.
