Method
- Prepare the Beef: In a medium bowl, combine the sliced sirloin steak with soy sauce, cornstarch, sesame oil, ground ginger, and garlic powder. Mix well and set aside to marinate for at least 15 minutes.
- Cook the Noodles: Cook the spaghetti noodles according to package directions until al dente. Drain and set aside. Rinse briefly with cold water to stop the cooking process and prevent sticking.
- Sear the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Add the marinated beef in a single layer (work in batches if necessary to avoid overcrowding) and sear for 2-3 minutes per side, until browned and cooked through. Remove the beef from the skillet and set aside.
- Sauté the Vegetables: Add another tablespoon of vegetable oil to the skillet. Add the sliced bell pepper and onion and sauté for 3-4 minutes, until slightly softened. Add the minced garlic and broccoli florets (and mushrooms, if using) and sauté for another 2 minutes, until fragrant and slightly tender-crisp.
- Make the Sauce: In a small bowl, whisk together the soy sauce, brown sugar, rice vinegar, honey, cornstarch, sesame oil, red pepper flakes (if using), and beef broth.
- Combine and Simmer: Pour the sauce over the vegetables in the skillet. Bring to a simmer, stirring constantly, until the sauce thickens, about 1-2 minutes.
- Add Beef and Noodles: Return the seared beef to the skillet and add the cooked spaghetti noodles. Toss everything together until the beef and noodles are evenly coated with the sauce.
- Serve: Serve immediately, garnished with sesame seeds and chopped green onions.
Notes
For best results, slice the beef thinly against the grain. Marinating the beef is crucial for tenderness and flavor. Do not overcrowd the skillet when searing the beef to ensure proper browning. Cook the noodles al dente to prevent them from becoming mushy. Adjust the amount of red pepper flakes to your spice preference. Leftovers can be stored in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave.
