01 - Cook noodles according to package directions until al dente. Drain thoroughly, reserving 1/4 cup pasta water. Set aside.
02 - Heat butter and olive oil in a large skillet or wok over medium heat. Add minced garlic and stir constantly for 1–2 minutes until fragrant and lightly golden, being careful not to burn.
03 - Reduce heat to low. Add soy sauce, oyster sauce, brown sugar, and black pepper. Stir thoroughly until sugar dissolves and ingredients are fully incorporated.
04 - Add cooked noodles to the skillet. Toss vigorously with tongs or wooden spoon until evenly coated in sauce. Add splashes of reserved pasta water if needed to achieve silky consistency.
05 - Remove from heat immediately. Sprinkle with scallions, Parmesan cheese, and sesame seeds as desired. Serve hot while aromatic.
