Boil water and cook noodles according to package instructions. Once cooked, stain and set aside. This should take anywhere from 5-12 minutes.
While the noodles are cooking, dice the shallot and mince the garlic. Start cooking the shallot chili oil sauce about 2 minutes before the noodles are done cooking.
Heat the oil in a saucepan on medium heat. Once hot, add in the shallots and garlic and sauté for 2-3 minutes.
Add in the red pepper chili flakes and gochugaru and saute with the shallots and garlic for another 30 seconds. Then, turn off the heat so you do not burn the ingredients.
Immediately add the soy sauce, dark soy sauce, black vinegar, and brown sugar to the saucepan and stir to mix for about 1 minute.
Once the sauce is combined and the sugar has dissolved completely, add in the cooked noodles and mix them with the sauce until coated.
Serve the shallot chili oil noodles hot or top with freshly chopped scallions and chili crisp for an even more delicious dish!
