Marinate the Beef: In a medium bowl, combine the thinly sliced beef with 1 tbsp light soy sauce, 1 tbsp cornflour, and 1 tsp toasted sesame oil. Use your hands to mix well, ensuring every piece is coated. Set aside for at least 15 minutes while you prepare everything else.

Mix the Sauce: In a separate small bowl or jug, whisk together all the sauce ingredients: light soy sauce, dark soy sauce, honey, rice vinegar, cornflour, and beef stock. Whisk until the cornflour is fully dissolved to avoid lumps later. Set aside.

Prepare your Wok: Place a wok or a large, heavy-bottomed frying pan over a high heat. Let it get smoking hot – this is crucial for a good sear. What works best for me is to let it heat for a good 2-3 minutes until you see faint wisps of smoke.

Sear the Beef: Add 1 tbsp of oil to the hot wok. Carefully add the beef in a single layer, working in two batches if necessary to avoid overcrowding the pan. Sear for 1-2 minutes per side until nicely browned but not cooked all the way through. Remove the beef with a slotted spoon and set it aside on a plate.

Stir-Fry the Aromatics and Vegetables: Add the remaining 1 tbsp of oil to the wok. Add the minced garlic, grated ginger, and the white parts of the spring onions. Stir-fry for about 30 seconds until fragrant. Add the broccoli florets and sliced carrots. Stir-fry for 3-4 minutes, adding a splash of water if needed to help steam the vegetables.

Add a Splash of Colour: Add the sliced red bell pepper to the wok and continue to cook for another 2-3 minutes. You want the vegetables to be crisp-tender, not soft and mushy.

Combine and Thicken: Return the seared beef to the wok. Give your sauce a final whisk and pour it all over the beef and vegetables. Stir constantly for 1-2 minutes. The sauce will bubble and thicken, coating everything in a beautiful, glossy glaze.

Finishing Touches: Turn off the heat. Stir in the green parts of the spring onions. Serve your sizzling beef stir fry immediately over rice or noodles, garnished with a sprinkle of toasted sesame seeds. If you enjoy spicy dishes, you'll love my Bang Bang Chicken Thighs recipe too!
