Ingredients You’ll Need

Beef & Marinade

• 1 pound beef ribeye or sirloin, very thinly sliced
  • Ask the butcher to slice it thin, or use hot pot / shabu-shabu sliced beef from an Asian market.
• 3 tablespoons soy sauce
• 2 tablespoons brown sugar or honey
• 1 tablespoon mirin or apple juice
• 1 tablespoon grated Asian pear or ripe bosc pear
  • Use 1 teaspoon sugar extra if you skip the pear.
• 1 tablespoon grated yellow onion
• 3 cloves garlic, minced
• 1 teaspoon fresh ginger, grated
• 1 tablespoon neutral oil (canola, avocado, or grapeseed)
• 1 teaspoon toasted sesame oil
• ½ teaspoon black pepper

Udon & Vegetables

• 3 packs (about 7 to 8 ounces each) pre-cooked udon noodles
  • Shelf-stable or frozen both work; frozen usually gives the best chewy texture.
• 1 tablespoon neutral oil
• 1 small yellow onion, sliced
• 1 small carrot, cut into matchsticks
• 1 small red bell pepper, thinly sliced
• 1 cup napa cabbage or green cabbage, shredded
• 1 cup mushrooms, sliced (shiitake or cremini)
• 2 to 3 green onions, cut into 1-inch pieces

Stir Fry Sauce

• 3 tablespoons soy sauce
• 1 tablespoon oyster sauce
• 1 tablespoon dark soy sauce or extra regular soy sauce
• 1 tablespoon brown sugar
• 2 teaspoons rice vinegar
• 2 teaspoons toasted sesame oil
• ¼ cup water or low-sodium beef broth
• 1 to 2 teaspoons gochujang (Korean chili paste), optional for heat

Garnishes

• 1 tablespoon toasted sesame seeds
• Extra sliced green onions
• Thinly sliced fresh red chili, optional

Pantry Shortcuts & Substitutions

• Use bottled bulgogi marinade instead of the homemade one if you need a shortcut; cut the sugar in the stir fry sauce slightly.
• Swap beef with thinly sliced chicken thighs or pork shoulder if you prefer.
• Use frozen stir fry veggie mix if you do not want to chop vegetables; just thaw slightly and pat dry.
• Use thick wheat noodles or even instant ramen bricks in a pinch, though udon gives the best chewy bite.

Equipment

• Large nonstick skillet or wok
• Medium pot for boiling udon
• Mixing bowls
• Cutting board and sharp knife
• Tongs or chopsticks for tossing noodles
• Measuring spoons and cups

Tips & Tricks

• Slice beef while it sits half-frozen so you get super thin pieces that cook quickly.
• Marinate the beef at least 20 minutes, or up to 8 hours in the fridge, so the flavors sink in and the pear tenderizes the meat.
• Loosen udon noodles in hot water just until they separate; do not boil them to death or they turn mushy.
• Pat vegetables dry so they stir fry nicely and do not steam in extra water.
• Heat the pan until it almost smokes before you add the beef so the meat caramelizes instead of stews.
• Cook the beef in batches if your pan feels crowded so you keep that nice browning.
• Stir the sauce ingredients in a bowl before you start cooking so you can pour and toss quickly.
• Taste at the end and adjust with a splash of soy for salt, sugar for sweetness, or gochujang for heat.

How to Make Bulgogi Beef Udon Stir Fry Recipe

Marinate the Beef

1. Add soy sauce, brown sugar, mirin, grated pear, grated onion, garlic, ginger, neutral oil, sesame oil, and black pepper to a bowl.
2. Stir until the sugar dissolves and the marinade looks glossy.
3. Add the thinly sliced beef and coat every piece with marinade.
4. Cover and chill for at least 20 minutes while you prep veggies, or up to 8 hours if you plan ahead.

Prep the Udon and Vegetables

1. Slice onion, carrot, bell pepper, cabbage, mushrooms, and green onions, and set them in separate piles.
2. Bring a medium pot of water to a boil, then turn the heat down to a gentle simmer.
3. Add the udon packs and loosen the noodles with chopsticks until they separate, usually 1 to 2 minutes.
4. Drain the noodles, rinse quickly with warm water, shake off extra water, and toss them with a tiny drizzle of oil so they do not clump.

Mix the Stir Fry Sauce

1. Add soy sauce, oyster sauce, dark soy sauce, brown sugar, rice vinegar, sesame oil, water or broth, and gochujang to a small bowl.
2. Whisk until the mixture looks smooth and the gochujang dissolves.
3. Taste a drop and adjust sweetness or salt to your liking.

Cook the Bulgogi Beef

1. Heat a large skillet or wok over medium-high heat until it feels very hot.
2. Add a little neutral oil, then spread half the marinated beef in a single layer.
3. Let the beef sear for 1 to 2 minutes without moving it, then stir and cook until the edges caramelize and the meat cooks through.
4. Transfer the cooked beef to a plate and repeat with the remaining beef, then set all the beef aside.

Stir Fry the Vegetables

1. Keep the same pan on medium-high heat and add a bit more oil if the pan looks dry.
2. Add sliced onion and carrot, and stir fry for 2 minutes until they start to soften.
3. Add bell pepper, cabbage, and mushrooms, and cook 3 to 4 minutes until the veggies turn tender-crisp.
4. Toss in the green onion pieces and cook 30 seconds so they keep some bite.

Bring It All Together

1. Add the drained udon noodles to the pan with the vegetables and toss gently with tongs.
2. Pour the stir fry sauce over the noodles and veggies, and toss until everything looks evenly coated.
3. Add the cooked bulgogi beef and any juices from the plate back into the pan.
4. Toss again for 1 to 2 minutes until the sauce thickens slightly and clings to the noodles and beef.

Finish and Serve

1. Turn off the heat and taste a noodle and a piece of beef.
2. Adjust seasoning with a splash of soy sauce or a pinch of sugar if you want more balance.
3. Sprinkle toasted sesame seeds, extra green onions, and sliced chili on top.
4. Serve the Bulgogi Beef Udon Stir Fry Recipe hot in big bowls, and watch it disappear fast.
