Ingredients
Scale
Beef Marinade
- 1 lb flank steak or sirloin, thinly sliced against the grain
- 2 tbsp cornstarch
- 2 tbsp soy sauce
Sauce
- ½ cup low-sodium soy sauce
- â…“ cup brown sugar (packed)
- ¼ cup water
- 2 cloves garlic, minced
- 1 tsp fresh ginger, grated (or ½ tsp ground ginger)
- 1 tbsp hoisin sauce (optional, for extra depth)
- ½ tsp red pepper flakes (optional)
Main Ingredients
- 8 oz lo mein, udon, or spaghetti noodles, cooked and drained
- 1 tbsp vegetable oil (or sesame oil for extra flavor)
- 4 green onions, sliced into 1-inch pieces
- 1 cup shredded carrots or thinly sliced bell peppers (optional)
Garnish
- Sesame seeds
- Additional green onions
Instructions
- Marinate the beef: In a bowl, toss the thinly sliced beef with cornstarch and soy sauce. Allow the beef to sit for 10 to 15 minutes to tenderize and absorb flavors while you prepare the sauce and cook the noodles.
- Make the sauce: In a small bowl or measuring cup, whisk together the soy sauce, brown sugar, water, minced garlic, grated ginger, hoisin sauce if using, and red pepper flakes for a balanced, flavorful sauce.
- Sear the beef: Heat vegetable or sesame oil in a large skillet or wok over medium-high heat. Add the beef slices in a single layer and sear for 1–2 minutes on each side until browned and just cooked through. Work in batches if necessary to avoid overcrowding. Remove the beef from the skillet and set aside.
- Cook the aromatics: In the same skillet, add a bit more oil if needed and sauté the green onions along with shredded carrots or thinly sliced bell peppers for 1–2 minutes until they begin to soften and release their fragrance.
- Bring it all together: Return the seared beef to the skillet. Pour the prepared sauce over the beef and vegetables, stirring to coat everything evenly. Simmer gently for 2–3 minutes until the sauce thickens slightly. Add the cooked noodles to the skillet and toss thoroughly until all ingredients are well combined and heated through.
- Serve hot: Garnish with sesame seeds and extra green onions for freshness and crunch. Serve immediately to enjoy the authentic takeout experience at home.
