Creating Chinese Ground Beef and Cabbage Stir-Fry is straightforward if you follow these clear steps:

1. Prepare Ingredients: Gather and chop all the ingredients before you start cooking for efficiency.
2. Heat Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.
3. Cook Beef: Add the ground beef to the skillet. Stir-fry until it’s browned and fully cooked. Drain excess fat if necessary.
4. Add Aromatics: Stir in the minced garlic and ginger. Cook for about 1 minute until fragrant.
5. Sauté Onions: Add the sliced onions to the skillet and stir-fry for another 2-3 minutes until they become translucent.
6. Cabbage Time: Incorporate the chopped napa cabbage into the skillet. Stir well and cook until it wilts down, about 3-4 minutes.
7. Season: Pour in the soy sauce, oyster sauce (if using), and a sprinkle of salt and pepper. Mix to combine evenly.
8. Thicken Sauce: In a small bowl, mix the cornstarch with a bit of water to create a slurry. Add it to the skillet and stir, cooking until the sauce thickens.
9. Finish with Sesame Oil: Drizzle the sesame oil over the stir-fry for an added flavor boost.
10. Garnish and Serve: Remove from heat and garnish with sliced green onions, if desired.

With these steps, you’ll have a delicious meal ready in no time!
