Prepare the scallion: cut these into 3-4 segments of around 3 inches (7.5 cm) each. From there, thinly slice or julienne the scallions. Separate the white and green parts. You can also thinly slice the scallions at an angle.
Heat a pot of water for the noodles. Once it boils, add in the noodles.
While the pot of water is heating for the noodles, heat a large wok or pan. Add 1/4 cup oil.
If using a wok, leave to heat on medium low heat. If using a regular pan, you can use medium heat. Add in the white part of the scallions.
Leave to cook over low heat (for wok) or medium (for pan) for 3-4 minutes or until lightly brown before adding the green parts. Leave to cook for 2-3 more minutes until brown and crisp.
When the scallions are lightly brown and crisp, remove the scallions from the oil.
Note: Be sure to keep a distance from your pan since the soy sauce can splatter when added to the oil.
Add in the sugar, soy sauce, dark soy sauce, and gochujang. Maintain the low medium/medium heat until the sugar dissolves. Lower the heat while the noodles are cooking.
Cook the noodles until still very chewy (do NOT overcook) and then drain from the water. You'll want the noodles to be very chewy so they won't overcook once added to the pan/wok.
After draining the noodles from the water, you can quickly run the noodles through water to remove excess starch.
Add the cooked noodles into the scallion oil and mix well to coat the noodles. Turn up the heat to medium then toss the noodles. Feel free to add more soy sauce, to taste, if needed.
Mix in the fried scallions and then add in the sesame oil. Turn off the heat.
Serve in a bowl enjoy while hot.
What to pair this with? You can enjoy this with any main dish of your choice! Think Korean braised tofu, pan-fried dumplings, maple hoisin tofu, steamed tofu with a soy garlic sauce, or wontons in chili broth --it's really up to you.
