Bring a large pot of salted water to a boil. Add your pasta and cook according to package instructions until al dente. Reserve 1/2 cup of pasta water before draining.
While the pasta cooks, heat a large skillet over medium heat. Add the diced pancetta and cook until crisp, about 5 to 7 minutes.
In a mixing bowl, whisk together eggs, Parmesan cheese, and black pepper until well combined.
Add the drained pasta to the skillet with the pancetta. Reduce heat to low and pour the egg and cheese mixture over the pasta. Toss quickly to coat the pasta without letting the eggs scramble.
Gradually add reserved pasta water to reach desired sauce consistency. The heat from the pasta will gently cook the eggs, creating a creamy sauce.
Season with salt to taste and serve immediately with additional grated Parmesan on top.
