Bring a large pot of water to a boil and cook the noodles according to the package directions.
While the noodles are cooking, add the oil, garlic, and red pepper flakes to a large nonstick pan over medium heat, stirring until the garlic is fragrant. Stir in the soy sauce, gochujang, and brown sugar.
When the noodles are ready, add them directly from the cooking pot to the pan and toss until all the noodles are glossy and coated. Loosen with 1-2 tbsp noodle water if needed. Enjoy!
