Step‑by‑Step Instructions for Chinese Beef and Onion Stir Fry
Step 1: Marinate the Beef
Begin by thinly slicing the flank steak against the grain and placing it in a bowl. Add the soy sauce and cornstarch, mixing well until the beef is evenly coated. Allow it to marinate for 15 minutes at room temperature to enhance tenderness and flavor, ensuring it’s more succulent when cooked.
Step 2: Cook the Beef
In a large skillet or wok, heat 2 tablespoons of vegetable oil over medium-high heat until shimmering, about 2 minutes. Carefully add the marinated beef to the hot oil, spreading it out evenly. Stir-fry for 3-4 minutes, until the beef is browned and no longer pink. Transfer the cooked beef to a plate and set aside.
Step 3: Stir-Fry the Vegetables
Return the skillet to the heat and add 1 tablespoon of vegetable oil. Once hot, toss in the sliced onion and bell pepper, stirring frequently for 3-5 minutes until the veggies are tender yet still crisp. The vibrant colors and enticing aromas should fill your kitchen, creating a delightful stir-fry foundation.
Step 4: Add Aromatics
Sprinkle in the minced garlic and grated ginger, stirring for an additional minute. This step infuses your Chinese Beef and Onion Stir Fry with a burst of flavor, as the garlic and ginger release their fragrant oils. Keep an eye on the vegetables to prevent them from burning.
Step 5: Combine Beef and Sauce
Return the cooked beef to the skillet along with the beef broth and oyster sauce. Stir everything together, ensuring the beef and vegetables are coated in the savory sauce. Cook for 2-3 more minutes until heated through, and the sauce has slightly thickened, giving a glossy finish to the dish.
Step 6: Finish and Serve
Drizzle the stir-fry with sesame oil for an authentic touch, then season with salt and pepper to taste. Remove from heat, garnish with freshly chopped green onions, and prepare to serve immediately. Your quick and flavorful Chinese Beef and Onion Stir Fry is now ready to devour, perfect over steamed rice or noodles!
