01 - Whisk together eggs, Parmesan cheese, heavy cream, and black pepper in a medium bowl until thoroughly 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 meat with slotted spoon and reserve, keeping rendered fat in skillet.
03 - Add minced garlic to the hot bacon fat. Sauté for 30 seconds until fragrant, being careful not to brown. Remove skillet from heat.
04 - Prepare ramen noodles according to package directions, omitting seasoning packets. Drain thoroughly, reserving 1/4 cup of cooking water for sauce adjustment.
05 - Add drained noodles to the skillet with garlic. Toss vigorously to coat evenly with rendered bacon fat.
06 - Working quickly with skillet off heat, pour egg-Parmesan mixture over noodles. Toss continuously and vigorously to emulsify eggs into a silky sauce, using residual heat. Add reserved pasta water if sauce appears too thick.
07 - Fold in crispy bacon pieces. Taste and adjust black pepper as needed. Plate immediately, topping with fresh parsley and additional grated Parmesan.
