Ingredients
- 12 oz spaghetti
- 4 oz guanciale
- 2 large eggs
- 1/2 cup Pecorino Romano cheese
- 1/4 cup Parmesan cheese
- 1/2 tsp freshly ground black pepper
- 1 tbsp salt
- 1/2 cup reserved pasta water
Instructions
- Step 1: Bring 4 quarts of water to a rolling boil in a large pot; add 1 tbsp salt and 12 oz spaghetti, then cook for 8-10 minutes until al dente, reserving 1/2 cup pasta water before draining.
- Step 2: In a medium bowl, whisk together 2 large eggs, 1/2 cup Pecorino Romano, 1/4 cup Parmesan, and 1/2 tsp black pepper until smooth and pale yellow.
- Step 3: Heat a large skillet over medium heat and add 4 oz guanciale; cook until crisp and golden, about 5 minutes, then remove from heat and let cool for 1 minute.
- Step 4: Add the drained spaghetti to the skillet with the guanciale and toss to coat, then immediately pour in the egg mixture while stirring vigorously to prevent scrambling; add 2 tbsp reserved pasta water and continue tossing for 1 minute until the sauce thickens and coats the strands without curdling.
- Step 5: Serve immediately with additional Pecorino Romano and black pepper.
