Ingredients

  • 8 oz Lo Mein Noodles
  • 1 lb Beef Sirloin thinly sliced
  • 1 Bell Pepper sliced
  • 1 Onion sliced
  • 2 cloves Garlic minced
  • 2 tablespoons Soy Sauce
  • 1 tablespoon Oyster Sauce
  • 1 tablespoon Cornstarch
  • 2 tablespoons Vegetable Oil
  • 1 tablespoon Sesame Oil
  • Salt and Pepper to taste
  • Green Onions chopped, for garnish

Instructions

  • Start by boiling the 8 oz of lo mein noodles according to the package instructions until they’re just al dente. Drain and rinse under cold water to stop the cooking process. Toss the noodles lightly with a little sesame oil to prevent sticking, then set aside.
  • In a mixing bowl, combine the thinly sliced beef sirloin with 1 tablespoon soy sauce, 1 tablespoon oyster sauce, and 1 tablespoon cornstarch. Mix well to coat every piece. Let it sit for 10-15 minutes.
  • Heat 1 tablespoon vegetable oil in your wok or skillet over medium-high heat. Add the sliced onion and bell pepper, stirring frequently for about 3-4 minutes until they just start to soften but remain crisp. Add the minced garlic and cook for another 30 seconds until fragrant. Remove the veggies from the pan and set aside.
  • Add the remaining 1 tablespoon vegetable oil to the wok and increase the heat to high. Add the marinated beef in a single layer. Let it sear undisturbed for about 1 minute, then stir-fry until all pieces are browned and cooked through, about 2-3 minutes.
  • Return the cooked bell peppers and onions to the pan. Add the cooked noodles and drizzle the remaining 1 tablespoon soy sauce over everything. Toss vigorously to combine all ingredients and heat through. Finish by drizzling sesame oil on top, then season with salt and pepper to taste.
  • Transfer your Pepper Steak Lo Mein to plates or a serving bowl. Garnish generously with chopped green onions for a fresh pop of flavor and color. Serve immediately for the best taste and texture.

Notes

  • Slice the beef sirloin thinly against the grain to ensure tenderness.
  • Rinse noodles with cold water and toss with sesame oil to prevent sticking.
  • Adjust cornstarch amount in the marinade to get the perfect sauce thickness.
  • Store leftovers in an airtight container in the fridge for up to 3 days; reheat gently with a splash of water.
  • For a vegetarian version, substitute oyster sauce with mushroom sauce and replace beef with tofu.
