Instructions
1PREPARE THE NOODLES: Bring a large pot of water to a boil and add the sweet potato glass noodles, stirring gently to prevent sticking. Cook for 4-5 minutes until the noodles are tender but still slightly chewy, testing one by breaking it between your fingers—it should bend rather than snap. Drain thoroughly in a colander and set aside to cool slightly, then drizzle with 1 tablespoon of sesame oil to prevent clumping.
2PREPARE THE INGREDIENTS: Slice the beef sirloin into thin strips about 2-3mm thick, cutting against the grain for maximum tenderness. Cut the carrots and onion into thin matchsticks about 2 inches long. Remove the stems from shiitake mushrooms and slice the caps into thin strips. Mince the garlic finely and prepare the fresh spinach by washing and removing any tough stems.
3MARINATE THE BEEF: In a small bowl, combine the sliced beef with 1 tablespoon of soy sauce, 1 minced garlic clove, and a pinch of salt and pepper. Let the beef marinate for at least 10 minutes while you prepare the remaining ingredients, allowing the flavors to penetrate the meat and enhancing its tenderness.
4COOK THE BEEF: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat until shimmering. Add the marinated beef in a single layer and cook for 2-3 minutes without stirring, allowing it to develop a light brown crust. Stir and cook for another 1-2 minutes until the beef is cooked through but still tender, then transfer to a plate.
5STIR-FRY THE VEGETABLES: In the same skillet, add 1 tablespoon of vegetable oil and stir-fry the mushroom slices over medium-high heat for 2-3 minutes until they release their moisture and become slightly golden. Add the minced garlic and cook for 30 seconds until fragrant, then add the carrot and onion matchsticks. Stir-fry for 2-3 minutes until the vegetables are tender-crisp with a slight bite remaining.
6COOK THE SPINACH: Push the vegetables to the side of the skillet and add the fresh spinach in batches, stirring until wilted, about 1-2 minutes total. Season with a pinch of salt and pepper, then transfer the spinach to the plate with the beef, keeping all cooked ingredients separate for now.
7COMBINE AND SEASON: Return the cooked noodles to the skillet over medium heat and add the remaining 2 tablespoons of soy sauce, 1 tablespoon of sesame oil, 1 tablespoon of sugar, and the remaining minced garlic. Toss everything together gently but thoroughly for 2-3 minutes, ensuring the noodles are evenly coated with the sauce and all ingredients are well distributed.
8FINISH THE DISH: Add all the cooked beef and vegetables back into the skillet with the noodles and toss everything together over medium heat for 1-2 minutes until well combined and heated through. Taste and adjust seasoning with additional soy sauce or salt as needed. Transfer to a serving platter and garnish generously with sesame seeds and additional minced garlic if desired, serving while warm.
