While the pasta is cooking, heat a large skillet over medium heat. Add the pancetta and cook until crispy, about 5 minutes.
Add the garlic and red pepper flakes to the skillet and cook for 30 seconds, until fragrant.
Stir in the heavy cream and Parmesan cheese. Bring to a simmer and cook until the cheese is melted.
In a separate bowl, whisk together the eggs.
Remove the skillet from the heat and stir in the eggs until they are just set.
Add the cooked pasta to the skillet and toss to coat.
Season with salt and pepper to taste.
Garnish with fresh parsley and serve immediately.
