Begin by preparing the chicken for your Chicken Broccoli Stir Fry. If using chicken breast, toss it lightly with baking soda and let it sit for about 20 minutes. If you're using chicken thighs, you can skip this step.

While the chicken is tenderizing, steam or boil the broccoli until it's bright green and tender but still firm, approximately 3-4 minutes. Drain it well and set it aside.

In a medium bowl, combine cornflour and light soy sauce, whisking until smooth and lump-free. Add in the remaining sauce ingredients: oyster sauce, Chinese cooking wine, and a splash of water.

Heat a tablespoon of oil in a large skillet or wok over high heat. Add minced garlic and diced onion, sautéing for about 10 seconds until fragrant and golden.

Add the tenderized chicken to the hot skillet, spreading it out in a single layer. Cook for about 2-3 minutes, stirring occasionally, until the chicken is just cooked through.

Stir in the pre-cooked broccoli alongside the sauce mixture, letting everything cook together for an additional 1-2 minutes.

Remove from heat and serve your Chicken Broccoli Stir Fry immediately, over steamed rice or cauliflower rice if desired.
