Step-by-Step Instructions
Prepare the noodles
Boil the sweet potato noodles according to package instructions (usually 6–7 minutes) until chewy and translucent. Drain, rinse with cold water, and cut into shorter lengths for easier eating.
Marinate the beef
In a bowl, combine sliced beef with 1 tbsp soy sauce, 1 tsp sesame oil, a pinch of pepper, and half the minced garlic. Let it sit for 10–15 minutes.
Blanch the spinach
Bring a pot of water to a boil, add spinach for 30 seconds, then drain and squeeze out excess water. Season lightly with a pinch of salt and 1/2 tsp sesame oil.
Cook the vegetables
Heat a skillet with a little oil. Sauté carrots for 1–2 minutes, then remove. Repeat with onions, bell peppers, and mushrooms, cooking each just until tender but still vibrant. Set aside.
Cook the beef
In the same pan, cook the marinated beef over medium-high heat until just browned. Remove from the pan.
Combine and season
In a large mixing bowl, combine noodles, vegetables, and beef. Add remaining soy sauce, sesame oil, sugar, green onions, and remaining garlic. Toss gently until well-coated and evenly mixed.
Garnish and serve
Transfer to a serving platter, sprinkle with toasted sesame seeds, and enjoy warm or at room temperature.
