1. Prepare the Ingredients

• Slice the flank steak against the grain into thin strips. This ensures tenderness when cooked.
• Wash and cut the broccoli into bite-sized florets. Pat dry to avoid excess moisture on the griddle.
• Mince the garlic and grate the ginger.

2. Make the Sauce

• In a bowl, whisk together soy sauce, oyster sauce, hoisin sauce, honey, rice vinegar, garlic, and ginger.
• Stir in the cornstarch slurry and sesame oil. Set aside.

3. Preheat the Blackstone Griddle

• Heat your Blackstone griddle to medium-high heat (about 400°F).
• Add 1 tablespoon of vegetable oil and spread it across the surface.

4. Cook the Broccoli

• Place the broccoli florets on the griddle.
• Cook for 3-4 minutes, stirring occasionally until they start to char but remain crisp.
• Push the broccoli to the cooler side of the griddle.

5. Sear the Beef

• Add another tablespoon of oil to the griddle.
• Spread out the sliced beef in a single layer.
• Sear for 2-3 minutes per side, until browned and caramelized.
• Sprinkle with salt, black pepper, and red pepper flakes.

6. Combine Everything

• Pour the sauce over the beef and toss to coat.
• Add the broccoli back to the center of the griddle.
• Stir-fry everything together for 2 more minutes, ensuring the sauce thickens and coats all ingredients.

7. Serve and Garnish

• Remove from the griddle and plate immediately.
• Sprinkle with sesame seeds and sliced green onions.
• Serve over steamed rice or noodles.
