Authentic Spaghetti alla Carbonara
The Ultimate Guide to Making Perfect, Creamy Roman Carbonara with Guanciale, Eggs, and Pecorino Romano
The Soul of Rome in a Bowl
There is something truly magical about Spaghetti alla Carbonara. It’s a dish that whispers of Roman alleyways and bustling trattorias, yet it’s deceptively simple to create in your own kitchen. The magic isn’t in a long list of ingredients, but in a delicate technique: the transformation of raw eggs and grated cheese into a luxuriously smooth, creamy sauce using only the heat from freshly cooked pasta and rendered pork fat. This isn’t a heavy, cream-laden imitation; it’s the real deal. The result is a pasta that is at once rich and light, salty from the cured guanciale, sharply complex from the Pecorino Romano, and wonderfully comforting. Mastering Carbonara is a rite of passage for any home cook, a lesson in timing and trust that yields one of the world’s most perfect plates of food.
A Testament to Simplicity
Spaghetti alla Carbonara is a pinnacle of Italian cucina povera, where a few humble ingredients are elevated through technique to create a masterpiece.
Ingredients
- 400g (14 oz) spaghetti
- 150g (5 oz) guanciale, diced (pancetta is a substitute)
- 4 large egg yolks
- 1 whole large egg
- 100g (1 cup) freshly grated Pecorino Romano cheese, plus more for serving
- Freshly cracked black pepper
- Salt for pasta water
Steps
- Bring a large pot of generously salted water to a boil for the pasta.
- While the water heats, combine the egg yolks, whole egg, grated Pecorino Romano, and a generous amount of black pepper in a medium bowl. Whisk until a thick, smooth paste forms.
- In a large skillet or pan, cook the diced guanciale over medium-low heat until it becomes crispy and its fat has rendered, about 5-7 minutes. Avoid burning. Remove from heat.
- Cook the spaghetti in the boiling water until it is al dente. Just before draining, reserve about 1 cup of the starchy pasta water.
- Working quickly, add the hot, drained spaghetti directly to the skillet with the guanciale and its fat. Toss vigorously to coat every strand.
- Remove the skillet from the heat entirely. Let it cool for about 1 minute to avoid scrambling the eggs.
- Slowly, while tossing the pasta continuously, pour the egg and cheese mixture into the skillet. The residual heat will cook the eggs into a creamy sauce.
- If the sauce seems too thick, add the reserved pasta water one tablespoon at a time, while tossing, until it reaches a silky, flowing consistency.
- Serve immediately, topped with an extra sprinkle of Pecorino Romano and a fresh crack of black pepper.
Variations
- Pancetta Carbonara: The most common substitute if guanciale is unavailable.
- Carbonara with Peas: Add a handful of fresh or frozen peas to the skillet with the guanciale for a pop of color and sweetness.
- Carbonara with Garlic: Add one smashed garlic clove to the guanciale as it cooks for a subtle aromatic note, removing it before adding the pasta.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheating is tricky. The best method is to gently reheat in a non-stick skillet over very low heat with a splash of water or milk, stirring constantly to re-emulsify the sauce. Microwaving will likely cause the eggs to curdle.

Frequently Asked Questions
Can I use bacon instead of guanciale or pancetta?
Short Answer: Yes, but the flavor profile will be different, as bacon is smoked.
Detailed Answer: Guanciale (cured pork jowl) and pancetta (cured pork belly) are not smoked, which allows the pure, salty, pork flavor to shine. Bacon’s smokiness will overpower the delicate egg and cheese sauce. If you must use bacon, blanch it in boiling water for 1-2 minutes first to reduce the smoky intensity. The texture will also be different, as bacon contains less fat than guanciale.
Why did my carbonara sauce scramble?
Short Answer: The heat was too high when you added the egg mixture.
Detailed Answer: Scrambling occurs when the eggs are cooked too quickly by excessive heat. The key is to remove the pan from the heat entirely and let it cool slightly before adding the egg and cheese mixture. The residual heat from the pasta and pan is sufficient to gently thicken the eggs into a creamy sauce (a process called tempering). If you’re nervous, you can also add a tablespoon of the hot pasta water to the egg mixture first to warm it up before adding it to the pasta.
Is it safe to eat raw eggs in carbonara?
Short Answer: The eggs are cooked by the residual heat of the pasta, but there is a minimal risk.
Detailed Answer: The hot pasta cooks the eggs to a safe temperature (160°F/71°C) through the process of tempering, which kills most bacteria. However, if you are pregnant, elderly, immunocompromised, or serving very young children, it’s advisable to use pasteurized eggs for complete safety. The risk from fresh, quality eggs is generally very low.
