Ingredients

Scale
  • 8 oz udon noodles (fresh or frozen)

  • 8 oz flank steak or sirloin, thinly sliced

  • 1 tbsp soy sauce (for beef marinade)

  • 1 tsp cornstarch (for beef marinade)

  • 1 tbsp vegetable oil (plus more for stir-frying)

  • 1/2 onion, sliced

  • 1 bell pepper, sliced

  • 2 cloves garlic, minced

  • 1 tsp ginger, minced

For the Sauce:

  • 2 tbsp soy sauce

  • 1 tbsp oyster sauce

  • 1/2 tbsp dark soy sauce (optional)

  • 1/4 cup water

  • 1 tsp cornstarch

  • 11.5 tsp freshly cracked black pepper

Instructions

  • Marinate sliced beef with soy sauce and cornstarch. Let sit for 10–15 minutes.

  • Prepare the sauce by whisking together soy sauces, oyster sauce, water, cornstarch, and black pepper.

  • Cook udon noodles according to package (or soak if frozen). Drain and set aside.

  • Heat oil in a wok over high heat. Sear beef until browned, about 2–3 minutes. Remove and set aside.

  • In the same pan, add more oil if needed. Sauté garlic and ginger, then add onions and bell peppers. Stir-fry 2–3 minutes.

  • Add cooked noodles and return beef to the wok. Pour in sauce and stir-fry until well-coated and glossy, 2–3 minutes.

  • Serve hot.

Notes

  • For extra spice, add chili flakes.

  • Substitute tofu for a vegetarian version.

  • Reheat with a splash of water to loosen the sauce.
