Start by slicing the cabbage thinly and evenly so it cooks at the same rate. Chop the mushrooms, green onions, garlic, and ginger ahead of time. Having everything ready makes stir-frying smooth and stress-free.
Place a large skillet or wok over medium-high heat. Add the sesame oil and allow it to warm until it shimmers slightly. This ensures your ingredients won’t stick and will cook evenly.
Add the ground beef to the hot pan and break it apart with a spoon. Cook for about 5–7 minutes until it’s fully browned and no pink remains. Drain excess fat if necessary, but leave a little for flavor.
Stir in the minced garlic and ginger once the beef is cooked. Sauté for about 30 seconds until fragrant. This step builds that classic savory aroma that makes the dish irresistible.
Add the sliced mushrooms and cabbage to the pan. Stir everything together so the vegetables mix evenly with the beef. Cook for about 5–6 minutes until the cabbage softens but still has a slight crunch.
Pour in the soy sauce and stir well to coat all ingredients evenly. Let it cook for another minute to blend the flavors. Sprinkle green onions on top and remove from heat before serving.
