01 - Whisk together eggs, Parmesan cheese, heavy cream, and black pepper in a medium bowl until fully combined. Set aside at room temperature.
02 - Place bacon or pancetta pieces in a large skillet over medium heat. Cook until crispy and fat has rendered, approximately 5-7 minutes. Remove with slotted spoon and set aside, leaving drippings in pan.
03 - Add minced garlic to the hot bacon fat. Sauté for 30 seconds until fragrant, being careful not to burn. Remove skillet from heat.
04 - Prepare ramen noodles according to package directions, omitting seasoning packets. Drain thoroughly, reserving 1/4 cup of noodle cooking water.
05 - Add drained noodles to the skillet with garlic. Toss vigorously to coat evenly with rendered bacon fat.
06 - With skillet completely off heat, pour egg-Parmesan mixture over noodles. Toss rapidly and continuously to prevent curdling while sauce thickens and coats noodles. Add splash of reserved pasta water if sauce becomes too thick.
07 - Fold cooked bacon pieces into coated noodles. Adjust seasoning with additional black pepper as needed.
08 - Plate carbonara ramen while hot. Garnish with fresh parsley and additional grated Parmesan cheese.
