Marinate the beef: In a bowl, toss beef with soy sauce, cornstarch, oil, and garlic powder. Let it marinate for 15–20 minutes (or longer if you have time).
Prepare the sauce: In a small bowl, whisk together soy sauce, oyster sauce, hoisin sauce, vinegar, sugar, broth, cornstarch, and pepper. Set aside.
Sear the beef: Heat a large skillet or wok over high heat. Add 1 tablespoon oil, then sear the beef in batches for 1–2 minutes per side until browned. Remove and set aside.
Sauté vegetables: In the same pan, add a little more oil if needed. Stir-fry onions, bell peppers, and garlic for about 3–4 minutes, until tender-crisp.
Combine & simmer: Return the beef to the pan. Pour in the prepared sauce and stir well. Cook for 2–3 minutes, until the sauce thickens and coats everything nicely.
Serve sizzling hot: Serve immediately over steamed rice, noodles, or cauliflower rice. Garnish with green onions or sesame seeds if desired.
🍽️ Tips & Variations
Add a dash of chili oil or crushed red pepper for spice.
Substitute chicken or tofu for the beef for a lighter version.
To make it extra “sizzling,” heat a cast-iron skillet before serving and pour the stir-fry over it just before eating — it’ll sizzle beautifully!
Would you like me to give you a restaurant-style sizzling plate version (with the sauce caramelized on a hot iron plate)? It’s incredibly aromatic and fun to serve!
