01 - Cook noodles according to package directions until al dente. Drain thoroughly, reserving 1/4 cup of the cooking liquid for later use.
02 - Heat butter and olive oil in a large skillet or wok over medium heat until melted. Add minced garlic and stir constantly for 1-2 minutes until fragrant and golden, taking care not to brown.
03 - Reduce heat to low. Pour in soy sauce, oyster sauce, brown sugar, and black pepper. Stir continuously until sugar dissolves and sauce is well combined.
04 - Add cooked noodles to the skillet. Toss vigorously using tongs to evenly coat every strand with sauce. Splash in reserved pasta water if mixture appears too thick.
05 - Remove from heat immediately. Scatter scallions, Parmesan cheese, and sesame seeds over the top. Serve while hot and steaming.
