Begin by filling a large pot with water and bringing it to a boil. Once boiling, add salt and spaghetti. Cook for 8-10 minutes until al dente, reserve a cup of pasta water, then drain and set aside.

In a large skillet, heat olive oil over medium heat. Add diced pancetta and cook for 4-5 minutes until crispy. If using garlic, add it now and sauté for an additional minute.

In a mixing bowl, whisk together eggs, grated cheese, and black pepper until creamy. This will be your sauce.

Transfer drained spaghetti to the skillet with pancetta. Toss to mix and distribute flavors, keeping it off heat.

Quickly pour the egg and cheese mixture over the hot pasta, stirring vigorously to integrate everything, adding reserved pasta water until silky and creamy.

Serve immediately, garnishing with additional cheese and parsley if desired. Enjoy!
