Instructions
Step 1. Cook the Pasta:
- Bring a large pot of salted water to a boil. Cook spaghetti until al dente. Reserve 1 cup of pasta water before draining.
Step 2. Prepare the Sauce:
- In a bowl, whisk together eggs, egg yolk, grated cheese, and black pepper until smooth. Set aside.
Step 3. Cook the Pancetta:
- While pasta cooks, heat a large skillet over medium heat. Add pancetta or bacon and cook until crispy. Turn off the heat.
Step 4. Combine Pasta & Sauce:
- Add hot, drained spaghetti directly to the skillet with pancetta. Toss quickly. Remove from heat and slowly add the egg-cheese mixture, stirring constantly.
Step 5. Create the Silky Texture:
- Add reserved pasta water a little at a time while tossing until the sauce becomes glossy and creamy.
- The heat from the pasta cooks the eggs gently without scrambling.
