Spaghetti Cacio e Pepe, Roman Cheese and Pepper Pasta
This cacio e pepe recipe tosses hot spaghetti with a creamy Pecorino Romano sauce and plenty of cracked black pepper — no cream, no butter, just cheese, pepper and starchy pasta water. One serving is about 272 g.
Cacio e pepe means cheese and pepper in the Roman dialect, and the dish comes from the shepherds of Lazio, who carried dried pasta, aged Pecorino and black peppercorns on long trips because all three kept without refrigeration. Tossed together with the starchy water the pasta cooked in, they made a hot, filling meal from almost nothing. It is one of Rome's four great pasta dishes, alongside carbonara, amatriciana and gricia.
Pairs well with: A crisp green salad and a glass of dry white wine

Execution Methodology & Culinary Technique
Prep Stage: Grate the Cheese and Crack the Pepper
10 Mins • Grating & Cracking
Grate the Pecorino as finely as you can — almost a powder — and put it in a wide bowl. Toast the peppercorns in a dry pan for a minute, crack them coarsely, and set a ladle and a jug by the stove: you will need the hot pasta water the moment the spaghetti is ready.
Maestro Tip: Fine grating is the whole trick. Coarse shreds of Pecorino melt into stringy clumps; a fine powder melts into a smooth cream.
2 Mins Medium heat, about 175°C (350°F)
Warm the peppercorns in a dry pan for 1–2 minutes until they smell warm and spicy, then tip them into a mortar or a bag and crack them coarsely — you want visible black specks, not dust.
Toasted pepper tastes rounder and warmer than raw ground pepper; skip this step and the dish tastes flat.
Done when: The peppercorns smell fragrant and crack into coarse, uneven pieces.
9 Mins Boiling water, 100°C (212°F)
Bring 2 litres of water to a rolling boil, add the salt and the spaghetti, and cook for 2 minutes less than the packet says. Before draining, scoop out at least 300 ml of the starchy pasta water into a jug — it is the sauce.
Less water than usual makes starchier pasta water, and starchy water is what makes the sauce cling.
Done when: The spaghetti is still firm in the middle when you drain it; the water looks cloudy and pale.
3 Mins Warm pasta water, about 60°C (140°F)
Put the grated Pecorino in a wide bowl with half the toasted pepper. Add the hot pasta water a ladleful at a time, stirring hard, until you have a thick, smooth cream about the texture of double cream. Let the water cool for a minute first if it is boiling — water that is too hot makes the cheese seize into lumps.
Patience here saves the dish: add the water slowly and stir constantly, and the cream stays smooth.
Done when: A glossy, lump-free cream that coats the back of a spoon.
4 Mins No direct heat
Tip the drained spaghetti into the bowl with the Pecorino cream, off the heat, and toss hard with tongs for 2–3 minutes, adding splashes of pasta water until every strand is coated in a glossy, clinging sauce. Fold in the rest of the pepper as you toss.
Keep the pan off the heat while you toss — direct heat is what turns Pecorino into rubbery clumps.
Done when: Every strand is coated in a pale, glossy sauce that clings instead of pooling in the bowl.
2 Mins No heat
Divide between warm bowls, scatter over a little extra grated Pecorino and a final crack of pepper, and serve immediately.
Warm bowls keep the sauce fluid for a few precious extra minutes.
Done when: Steaming bowls with a creamy, pepper-flecked coating on the pasta.
Finishing Touches & Plating
Serve immediately in warm bowls with an extra snowfall of Pecorino and a final crack of pepper — the sauce sets fast, so do not let it sit.

Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Vegetables
Green Salad
A sharp, lemony green salad cuts the richness of the cheese and resets the palate between bites.
Sides
Burrata and Tomatoes
Cool, creamy burrata with ripe tomatoes is the gentle opposite of the hot, peppery pasta.
Drinks
Dry White Wine
A crisp Vermentino or Pinot Grigio lifts the salty Pecorino and stands up to the black pepper.
Complete menu
Start with a green salad, serve the cacio e pepe as the main with burrata and tomatoes, and finish with fresh fruit.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Go Easy on Extra Cheese
Pecorino Romano is very salty and rich in saturated fat, so a second helping of cheese on top adds a lot of sodium and fat to an already rich plate. One measured portion is the dish. This is general food information, not medical advice.
Skip Extra Salt
The cheese seasons the sauce on its own, so extra salt in the pasta water or at the table pushes the sodium up fast — about 434 mg per serving already. Taste before you reach for the salt. This is general food information, not medical advice.
