How to Make Bulgogi Beef Udon Stir Fry: Step-by-Step

1. Marinate the Beef

In a mixing bowl, combine the soy sauce, brown sugar, sesame oil, rice vinegar, garlic, ginger, and black pepper. Add thinly sliced beef and toss to coat thoroughly. Let it marinate for at least 10–15 minutes (or up to overnight in the fridge). This allows the beef to absorb deep flavor and become tender.

2. Prepare the Udon Noodles

If using frozen udon, bring a pot of water to a boil and blanch the noodles for about 1–2 minutes until loosened. Drain and rinse under cold water. Set aside. Skip this step if using shelf-stable pre-cooked udon.

3. Sear the Marinated Beef

Heat 1 tablespoon of oil in a large skillet or wok over high heat. Add the marinated beef in a single layer (work in batches if needed) and sear for 2–3 minutes until nicely browned and caramelized. Remove and set aside.

4. Stir-Fry the Vegetables

In the same skillet, add another tablespoon of oil if needed. Sauté the onions and carrots over medium-high heat for 2–3 minutes until just tender but still slightly crisp. Toss in the greens and stir until wilted, about 1 minute.

5. Add Noodles and Combine

Add the prepared udon noodles and seared beef back into the pan with the vegetables. Stir-fry everything together for another 2–3 minutes. Add a splash of soy sauce or reserved marinade if you want extra sauce. Toss until noodles are evenly coated and heated through.

6. Garnish and Serve

Turn off heat. Garnish with chopped green onions and a sprinkle of sesame seeds. Serve immediately while hot and glossy.

How to Store and Reheat

Refrigerator:
Store cooled leftovers in an airtight container for up to 3 days.

Freezer:
Not recommended due to the texture of udon noodles after thawing, but the marinated beef can be frozen separately.

Reheat:
Reheat in a skillet with a splash of water or broth over medium heat, stirring until warmed through. Microwave in 1-minute bursts if you’re in a rush.
