Boil the instant noodles for approximately 2 minutes, ensuring they remain slightly firm as you are going to have to stir again later. Once that is done, drain the water and remove the instant noodles from the wok.
Using the same wok or pot on medium-high heat, add 1 teaspoon of cooking oil and 1 pack of seasoning oil from the instant noodle package. Then, add the minced garlic and stir until fragrant.
Add the cooked instant noodles to the wok and coat them with oyster sauce, soy sauce, sweet soy sauce, sugar, and chili flakes. Stir quickly until the noodles are evenly coated with the sauce.
