This easy Kimchi Udon Noodles with scallions recipe is a sweet & spicy stir fry Korean noodles that's better than Buldak Ramen. On the family dinner table in 15 minutes, it's the perfect spicy Asian lunch or quick dinner at home. (No Meat/ No Cream/ No Gochujang)

Ingredients
You will need a few simple ingredients for this spicy Korean noodles:
- 2 packets of Udon noodles: I used frozen udon but you can also use fresh- just make sure you cook it as per the packet instructions.
- 1 Tablespoon of unsalted butter: I don't recommend using regular vegetable oil as the butter adds so much flavor
- ½ onion: I used a red onion for its sweetness but you can also use shallots- peel and slice.
- 3 garlic cloves: peeled and sliced
- ½ Cup of baechu (cabbage) kimchi: add any juices to the stir fry too
- 2 Tablespoons oyster sauce
- ½ teaspoon of white sugar: the older your kimchi, the more sour it will be. My kimchi was relatively fresh. If you are using very aged kimchi, you may need more sugar. I will also suggest adding either bacon, pork belly, or sesame oil (the extra oil helps to temper the sourness of the sauce)- the sesame oil can be added as a finishing oil. If adding bacon or pork belly, add it after sautéing the aromatics but before the kimchi.
- 1 teaspoon of dark soy sauce: this is not typical in most kimchi noodle recipes, but I found the color a bit light without. Adding it made the dish look much more appetising. (See below for comparison.)
- spring onions: the freshness of the spring onions is a good contrast to the kimchi flavor
- gochugaru: I omitted the red chili flakes but you can add them or ½-1 teaspoon of Gochujang Paste if you want more spice. If you have both, I'd go with the paste as it makes the noodles look more tasty. (See below.)
- egg: this is optional but a runny egg yolk tastes so good with the kimchi sauce
