Get the pasta cooking first, then whisk up 3 large eggs, 1/2 cup grated Parmesan and a pinch of salt. Set aside. In a large skillet, cook 4 oz pancetta or bacon over medium heat until crispy, then remove from heat. Add 1/2 cup chopped fresh parsley to the pan and let it wilt for a bit. Now add your cooked spaghetti to the pan, tossing everything together. Pour in the egg mixture, stirring constantly with a fork until it’s all nice and creamy. Finally, add another sprinkle of Parmesan and you’re done!
