1-Step 1: Marinate the Beef First, mix 1 lb of flank steak cut into 1/4 inch strips with 1/4 teaspoon baking soda, 1 teaspoon white pepper, 1 tablespoon soy sauce, 2 tablespoons cornstarch, and 1 egg white. Let it marinate in the refrigerator for 30 minutes to tenderize and infuse flavors. This step ensures the beef stays juicy and absorbs the seasonings well.

2-Step 2: Fry the Beef After marinating, dust the beef with additional cornstarch. Heat 3 cups of neutral oil in a pan to 350°F (175°C) and fry the strips for 3-4 minutes until golden brown. Once done, set the beef aside to rest, keeping it crispy for later.

3-Step 3: Sauté the Vegetables In a separate pan, use 2 tablespoons of neutral oil over high heat to sauté the 1 red bell pepper and 1 white onion, both cut into 2-inch pieces, along with 2 cloves of minced garlic. Cook for about 2 minutes until they’re crisp-tender and aromatic.

4-Step 4: Combine and Sauce Add the fried beef back to the pan with the vegetables. Pour in the sauce mixture made from 1/2 cup water, 2 tablespoons soy sauce, 1/4 cup hoisin sauce, 3 tablespoons oyster sauce, 1/4 cup sugar, 3 tablespoons sriracha, and 2 tablespoons ketchup. Stir everything together until well combined.

5-Step 5: Finish and Serve Finally, add the 2 tablespoons of vinegar and the slurry (1 tablespoon cornstarch mixed with 1 tablespoon water). Stir for 1-2 minutes until the sauce thickens to a glossy coat. Serve hot over rice for a complete meal. For more ideas on easy recipes, try this simple chicken spaghetti recipe from our site.
