First, whisk together all stir-fry sauce ingredients in a small bowl. Then set the sauce aside.
½ tablespoon gochugaru, 1 tablespoon gochujang, 1 tablespoon kimchi juice, 1 tablespoon dark soy sauce, 1 tablespoon oyster sauce, 1 tablespoon mirin, ½ tablespoon honey, ¼ teaspoon black pepper
Place the udon noodles in a bowl or pot filled with boiling water. Let them sit until they are easy to detangle. Remove them from the water and set the noodles aside. The udon noodles shouldn't be cooked fully at this point as they will be stir-fried later.
2 7-ounce packets pre-cooked udon noodles
In the meantime, preheat some vegetable oil in a pan over medium to medium-low heat. Add the garlic and white green onion parts. Sauté until fragrant. Then add the kimchi and sauté for 1 minute.
1 tablespoon vegetable oil, 1 - 2 garlic cloves, 2 green onions, ⅔ cup kimchi
Next, add the carrots and mushrooms. Stir-fry everything over medium heat until the vegetables have softened.
1 carrot, 4 mushrooms
Now add the udon noodles, remaining green onion parts, and stir fry sauce. Toss and continue to stir fry until everything is combined and the sauce is sticking to the noodles.
Garnish with chopped roasted nori, sesame seeds, and a fried egg (optional). Enjoy!
