Ingredients You’ll Need
Beef and Marinade

- 3 tablespoons soy sauce (use low sodium if you prefer)
- 1 tablespoon dark soy sauce (optional, adds deeper color and flavor)
- 2 tablespoons brown sugar or coconut sugar
- 1 tablespoon honey
- 2 tablespoons grated Asian pear or apple
- Canned pear juice works in a pinch as a shortcut.
- 3 cloves garlic, minced
- 1 tablespoon grated fresh ginger
- 1 tablespoon toasted sesame oil
- 1–2 tablespoons gochujang (Korean chili paste), to taste
- Use 1 teaspoon if you want mild heat.
- 1 tablespoon rice vinegar or apple cider vinegar
Noodles and Veggies
- 14–16 ounces fresh or frozen udon noodles
- Shelf-stable udon works too; follow package directions before stir frying.
- 2 tablespoons neutral oil (canola, avocado, or grapeseed)
- 1 medium yellow onion, thinly sliced
- 2 medium carrots, cut into matchsticks or thin half-moons
- 1 small red bell pepper, thinly sliced
- 2 cups napa cabbage or green cabbage, shredded

- 2 teaspoons minced garlic (extra, for stir fry)
- 1 teaspoon grated ginger (extra, for stir fry)
Sauce For Stir Fry
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce or vegetarian mushroom stir fry sauce
- 1 tablespoon mirin or a splash of apple juice
- 1 teaspoon sugar (optional, adjust to taste)
- 2–3 tablespoons water or low sodium beef broth
Toppings
- Toasted sesame seeds
- Extra sliced green onions
- Thinly sliced fresh chili or a sprinkle of red pepper flakes (optional)
Equipment
- Large nonstick skillet, wok, or wide Dutch oven
- Cutting board and sharp knife
- Mixing bowl for marinade
- Tongs or chopsticks for tossing noodles
- Small bowl and whisk for stir fry sauce
Tips & Tricks
- Slice beef very thin so it cooks quickly and stays tender; chill it slightly to make slicing easier.
- Marinate the beef at least 20 minutes, and up to 24 hours in the fridge, for deeper bulgogi flavor.
- Use frozen udon noodles if you can; they usually give the best chewy texture.
- Loosen udon in hot water for 1–2 minutes before stir frying so they separate easily.
- Cook veggies just until crisp-tender so they keep some bite and do not turn soggy.
- Stir fry in batches if your pan feels crowded; too much food in the pan can steam instead of sear.
- Taste the sauce at the end and adjust with soy for salt, sugar or honey for sweetness, and vinegar for brightness.
- Keep the noodles moving in the pan so they soak up sauce evenly and do not stick.
How to Make Bulgogi Beef Udon Stir Fry Recipe
Step 1: Marinate the bulgogi beef
Add sliced beef to a mixing bowl. Stir in soy sauce, dark soy sauce, brown sugar, honey, grated pear, garlic, ginger, sesame oil, gochujang, and rice vinegar. Toss until every slice of beef looks coated and glossy, then cover and chill at least 20 minutes while you prep everything else.
Step 2: Prep noodles and sauce
If you use frozen or fresh udon, place them in a bowl and cover with very hot tap water for 1–2 minutes until they loosen, then drain well. If you use shelf-stable udon, cook them according to package directions, undercook by 1 minute, then drain and rinse quickly to stop cooking. In a small bowl, whisk together soy sauce, oyster sauce, mirin, sugar, and water or broth, then set the sauce near the stove.
Step 3: Sauté veggies and aromatics
Heat 1 tablespoon neutral oil in a large skillet or wok over medium-high heat. Add onion and carrots and cook 3–4 minutes until they start to soften. Stir in bell pepper, mushrooms, and the white parts of the green onions, then cook 3–4 minutes until veggies turn crisp-tender. Add minced garlic and grated ginger and cook 30–60 seconds until fragrant, then transfer veggies to a plate.
Step 4: Sear the bulgogi beef
In the same pan, add the remaining 1 tablespoon oil and increase heat to high. Add marinated beef in a single layer, working in two batches if needed so the meat sears instead of steams. Cook 2–3 minutes, flipping once, until the edges caramelize and the beef cooks through, then return all beef to the pan.
Step 5: Bring noodles, beef, and veggies together
Lower heat to medium-high and add the drained udon noodles to the pan with the beef. Pour in the stir fry sauce and toss with tongs until the noodles soak up the sauce and turn glossy. Add the cooked veggies back to the pan, sprinkle in the green parts of the green onions, and toss 1–2 minutes until everything heats through and the sauce coats the noodles evenly. Taste and adjust seasoning with a splash of soy, a pinch of sugar, or a little extra gochujang if you want more heat.
Step 6: Finish and serve
Turn off the heat and sprinkle the top with toasted sesame seeds and extra green onions. Add fresh chili slices or red pepper flakes if you like a spicy kick. Serve the Bulgogi Beef Udon Stir Fry Recipe hot in big bowls and eat it while the noodles stay bouncy and the sauce still clings to every strand.
What to Serve with Bulgogi Beef Udon Stir Fry Recipe
Serve this Bulgogi Beef Udon Stir Fry Recipe with a simple cucumber salad, kimchi, or a crunchy cabbage slaw to balance the rich noodles. Steamed broccoli or snap peas also pair nicely and cook quickly while the noodles simmer. You can pour iced green tea, barley tea, or sparkling water with citrus on the side to keep things refreshing. If you cook for kids, add some sliced fruit like oranges or pineapple to cool the heat.
Storage Options
- Store leftovers in an airtight container in the fridge for up to 3 days.
- Reheat in a skillet over medium heat with a splash of water or broth until the noodles loosen and warm through.
- You can freeze portions in freezer-safe containers for up to 2 months, though the noodles may soften slightly.
- Thaw frozen portions in the fridge overnight, then reheat on the stove and adjust seasoning with a bit of soy sauce or sesame oil.
