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 Dish
- 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)
- Sesame seeds & more green onions, for garnish
Instructions
- Marinate the beef: In a bowl, toss the thinly sliced beef with cornstarch and soy sauce. Let it sit for 10–15 minutes to absorb flavors and tenderize while preparing the sauce and noodles.
- Make the sauce: In a small bowl or measuring cup, whisk together the low-sodium soy sauce, brown sugar, water, minced garlic, grated ginger, hoisin sauce (if using), and red pepper flakes. Set aside.
- Sear the beef: Heat vegetable or sesame oil in a large skillet or wok over medium-high heat. Add the beef in a single layer, working in batches if necessary. Sear for 1–2 minutes per side until browned and just cooked through. Remove the beef from the skillet and set aside.
- Cook the aromatics: In the same pan, add a little more oil if needed. Sauté the sliced green onions and shredded carrots or bell peppers for 1–2 minutes until slightly softened and aromatic.
- Bring it all together: Return the seared beef to the skillet. Pour in the prepared sauce and stir to coat the meat evenly. Let the mixture simmer for 2–3 minutes until the sauce thickens slightly. Add the cooked noodles and toss everything together to combine thoroughly and warm through.
- Serve hot: Transfer to serving plates, garnish with sesame seeds and extra green onions, and enjoy the vibrant takeout-style flavors immediately.
Notes
- For best results, slice the beef thinly across the grain to ensure tenderness.
- Feel free to substitute beef with chicken or tofu for variation.
- Adjust the red pepper flakes to taste for desired spiciness.
- Use sesame oil instead of vegetable oil to add a nutty flavor.
- The optional hoisin sauce adds depth but can be omitted if unavailable.
- Leftovers keep well refrigerated for up to 2 days and can be reheated in a skillet or microwave.
