Pasta alla Carbonara

Carbonara is gricia with egg added — guanciale fat, Pecorino Romano, and a raw egg yolk mixture cooked by the heat of the pasta alone. No cream. No peas. No onion.

The technique is the single point of failure: too much heat scrambles the eggs. Too little heat produces a raw, runny sauce. The correct temperature is approximately 65°C — achieved by removing the pan from heat and using pasta water to regulate.

Ingredients (4 servings)

  • 320g dry pasta (spaghetti or rigatoni)
  • 100g guanciale, cut into 1cm lardons
  • 200g eggs (4 large eggs, approximately 50g each)
  • 80g Pecorino Romano DOP, finely grated
  • 4g black pepper, coarsely cracked

Instructions

1. Prepare the egg mixture Beat the eggs in a bowl. Add the grated Pecorino Romano and half the black pepper. Mix well. The mixture should be smooth and thick. Set aside.

2. Cook the pasta Bring a large pot of lightly salted water to a boil. Cook pasta to package time.

3. Render the guanciale Place guanciale in a cold, dry pan. Render over medium heat for 5–7 minutes until golden. Remove guanciale pieces with a slotted spoon. Leave the fat in the pan. Turn heat to low.

4. Temper the eggs Before draining the pasta, ladle 2–3 tbsp of hot pasta water into the egg mixture. Mix quickly — this begins to warm the eggs and prevents scrambling on contact with the hot pasta.

5. Combine off heat Drain the pasta. Remove the pan from heat entirely. Add the pasta to the pan with the guanciale fat. Wait 30 seconds for the pan to cool slightly.

6. Add egg mixture Pour the egg mixture over the pasta. Toss constantly and vigorously. The egg should thicken and coat the pasta without scrambling. Add pasta water 1 tbsp at a time to loosen the sauce and regulate temperature.

7. Serve Add the guanciale pieces. Add remaining cracked pepper. Serve immediately — carbonara does not hold.

Notes

The two technical risks: scrambled eggs (too much heat), and a watery sauce (insufficient emulsification). The solution to both is the same — remove from heat before adding eggs, and toss constantly.

Authentic carbonara uses whole eggs or a mix of whole eggs and yolks. Using only yolks (sometimes suggested) produces a richer but heavier sauce. Four whole large eggs for 320g pasta is the baseline.

Cost Context

At Italian supermarket prices (Q1 2025): pasta-secca (€1.65/kg), guanciale (€15.00/kg), uova (€5.00/kg, 200g = 4 eggs), pecorino-romano (~€13.50/kg), pepe-nero (€20.00/kg). Total for 4 servings is approximately €4.20 — roughly €1.05 per serving. The highest-cost recipe in the Roman quartet.
