01 - Bring a large pot of water to a rolling boil. Add instant ramen noodles and cook for approximately 3 minutes as directed on the package. Reserve 1/2 cup of cooking water, then drain the noodles thoroughly.
02 - In a mixing bowl, whisk together eggs, grated Parmesan cheese, heavy cream, freshly ground black pepper, and crushed red pepper flakes until the mixture becomes smooth with no streaks.
03 - In a skillet over medium heat, cook diced pancetta or bacon for about 5 minutes until golden and crisp. Stir in minced garlic and sauté for 30 seconds until aromatic.
04 - Lower the heat to low and add drained ramen noodles to the skillet, tossing so the noodles absorb the rendered fats evenly.
05 - Remove the skillet from the heat. Immediately pour the prepared egg mixture over the noodles, tossing briskly to create a creamy sauce. Adjust consistency with a splash of reserved noodle water as required.
06 - Portion noodles into two bowls. Top with sliced scallions, toasted sesame seeds, and a drizzle of sriracha or chili oil if desired. Present hot.
