Ingredients

Scale
  • 1 pound sirloin steak, thinly sliced
  • 1 pound thick wheat noodles (udon or similar)
  • 2 tablespoons soy sauce
  • 1 tablespoon sesame oil
  • 1 teaspoon black pepper
  • 1 tablespoon vegetable oil
  • 1 medium yellow onion, sliced
  • 2 cloves garlic, minced
  • 1 cup sliced carrots
  • 1 cup sliced mushrooms
  • 1/4 cup gochujang (Korean chili paste)
  • 2 tablespoons soy sauce
  • 1 tablespoon brown sugar
  • 1 tablespoon rice vinegar
  • 1 teaspoon grated fresh ginger
  • 1/4 cup water
  • 2 scallions, chopped (for garnish)
  • 1 teaspoon sesame seeds (for garnish)

Instructions

  1. In a bowl, toss the sliced beef with 2 tablespoons soy sauce, sesame oil, and black pepper. Set aside for 10 minutes.
  2. Cook the noodles according to package directions. Drain them and rinse briefly with cold water to stop cooking. Toss with a little oil to prevent sticking.
  3. While the noodles cook, prepare the sauce: Whisk together gochujang, 2 tablespoons soy sauce, brown sugar, rice vinegar, ginger, and water in a small bowl.
  4. Heat the vegetable oil in a large skillet or wok over medium-high heat. Add the beef and stir-fry until browned, about 3-4 minutes. Remove the beef and set it aside.
  5. Add the onion, garlic, carrots, and mushrooms to the same skillet. Stir-fry until the vegetables are tender-crisp, about 5 minutes.
  6. Return the cooked beef to the skillet. Add the cooked noodles.
  7. Pour the prepared gochujang sauce over the noodles and beef. Toss everything together quickly until the noodles are evenly coated and heated through, about 2 minutes.
  8. Serve immediately. Garnish your savory Korean beef noodle dish with chopped scallions and sesame seeds.

Notes

  • For a milder flavor, reduce the gochujang to 2 tablespoons.
  • If you prefer glass noodles beef stir fry, substitute sweet potato starch noodles (dangmyeon) for the wheat noodles; adjust cooking time as needed.
  • You can substitute thinly sliced pork shoulder for the beef if desired.
