🛒 Ingredients

To get that rich, savory sauce and perfectly cut ingredients shown in image_229376.jpg, you will need:

For the Beef & Marinade:

• 1 lb (450g) of Flank Steak, Sirloin, or Ribeye (sliced thinly against the grain)
• 1 tablespoon of Soy Sauce
• 1 tablespoon of Cornstarch (the secret to velvet-tender beef)
• 1 teaspoon of Vegetable oil

The Savory Stir-Fry Sauce:

• 3 tablespoons of Soy Sauce
• 2 tablespoons of Oyster Sauce
• 1 tablespoon of Brown Sugar (or honey)
• 1 teaspoon of Coarsely Ground Black Pepper
• 1/4 cup of Low-sodium Beef Broth or Water

The Vegetables (As seen in image_229376.jpg):

• 1 Medium Red Bell Pepper, sliced into chunks
• 1 Medium White Onion, chopped into square petals
• 3 to 4 stalks of Green Onions (Scallions), cut into 2-inch pieces
• 3 cloves of Garlic, minced
• 1 teaspoon of Fresh Ginger, minced
• 2 tablespoons of Cooking Oil (for frying)

📋 Step-by-Step Instructions

Follow these simple steps for a perfect wok-style sizzle:

1. Velvet the Beef: In a bowl, toss your thinly sliced beef with the soy sauce, cornstarch, and a teaspoon of oil. Let it marinate at room temperature for 10 minutes. This cornstarch coating locks in the juices so the beef stays incredibly tender.
2. Mix the Glaze: In a small bowl, whisk together the stir-fry sauce ingredients (soy sauce, oyster sauce, brown sugar, black pepper, and beef broth) until the sugar dissolves. Set it aside.
3. Sear the Beef: Heat a large skillet or wok over high heat with 1 tablespoon of oil. Add the beef slices in a single layer. Sear without moving for 1 minute to get a nice brown crust, then flip and cook for 1 more minute. Remove the beef and set aside (it should not be fully cooked through yet).
4. Stir-Fry the Veggies: Add another tablespoon of oil to the same pan over medium-high heat. Toss in the minced garlic, ginger, chopped white onion, and red bell peppers. Stir-fry for 2 to 3 minutes until the vegetables are vibrant but still crisp, matching the look in image_229376.jpg.
5. Bring it Together: Pour the sauce mixture into the pan and let it come to a simmer. Toss the beef back into the pan along with the green onion pieces. Stir everything together quickly for 1 to 2 minutes until the sauce bubbles up and thickens into a beautiful, glossy glaze coating every piece, exactly like image_229376.jpg.
6. Serve: Remove from heat and serve hot over a bowl of steamed white rice or noodles.
