Ingredients
  

The Chicken Marinade (Velveting Step)
  • 1.2 lbs boneless skinless chicken breasts cut into bite-sized cubes
  • 1 tbsp soy sauce
  • 1 tbsp cornstarch
  • 1 tbsp chicken broth or water
The Stir-Fry Base
  • 1 large head of fresh broccoli cut into small florets
  • 8 oz 225g cremini or button mushrooms, thickly sliced
  • 1 medium white or yellow onion chopped into cubes
  • 3 cloves garlic finely minced
  • 1 tbsp fresh ginger finely grated
  • 3 tbsp olive oil divided for cooking
  • Optional garnish: A pinch of crushed red pepper flakes and freshly chopped parsley or green onions
The Savory Brown Sauce
  • ½ cup chicken broth or stock
  • ¼ cup low-sodium soy sauce
  • 2 tbsp oyster sauce
  • 1 tbsp honey
  • 1 tsp toasted sesame oil
  • 1 tsp cornstarch

Method
 

  1. Marinate the Chicken: In a medium bowl, combine the cubed chicken with 1 tbsp soy sauce, 1 tbsp chicken broth, and 1 tbsp cornstarch. Toss well to coat evenly and let it sit at room temperature for 15 minutes while you prepare the vegetables.
  2. Mix the Stir-Fry Sauce: In a separate small bowl or measuring cup, whisk together all the sauce ingredients: ½ cup chicken broth, ¼ cup low-sodium soy sauce, 2 tbsp oyster sauce, 1 tbsp honey, 1 tsp toasted sesame oil, and 1 tsp cornstarch. Whisk thoroughly until smooth and set aside.
  3. Sear the Chicken: Heat 1.5 tablespoons of olive oil in a large skillet or wok over high heat until shimmering. Add the marinated chicken pieces in a single layer. Cook undisturbed for 2 minutes to get a nice golden sear, then toss and stir-fry for another 2 minutes until just cooked through. Remove the chicken and its juices to a clean plate.
  4. Cook the Aromatics & Veggies: Wipe out any burnt bits from the pan, add the remaining 1.5 tablespoons of olive oil, and drop the heat to medium-high. Stir-fry the chopped onions, minced garlic, and grated ginger for about 1 minute until fragrant. Add the broccoli florets and sliced mushrooms. Stir-fry for 3 to 4 minutes until the broccoli turns bright green and the mushrooms soften.
  5. Combine and Thicken: Return the cooked chicken and any resting juices back into the skillet with the vegetables. Give your prepared sauce mixture a quick stir (to redistribute the cornstarch) and pour it directly over the ingredients. Bring everything to a simmer for 1 to 2 minutes. The sauce will quickly bubble and thicken into a glossy glaze that coats everything beautifully.
  6. Garnish and Serve: Remove from the heat and transfer onto a serving platter. Sprinkle with crushed red pepper flakes for heat and chopped parsley or green onions for freshness. Serve hot alongside steamed brown rice, quinoa, or noodles.

Notes

  • The Secret to Tenderness (Velveting): Do not skip the 15-minute marination step with cornstarch! This authentic technique creates a protective barrier around the chicken breast cubes, locking in the natural juices and ensuring the meat stays incredibly soft and juicy under high-heat wok cooking.
  • Gluten-Free Modification: To make this recipe completely gluten-free, substitute the standard soy sauce with certified gluten-free tamari or coconut aminos, and ensure your oyster sauce is labeled gluten-free.
  • High-Heat Success: Stir-frying happens fast. Prep all your vegetables, cube your chicken, and completely whisk your savory brown sauce before turning on the stove. Make sure your skillet or wok is shimmering hot before adding the oil to prevent the vegetables from steaming and becoming mushy.
  • Meal Prep & Storage: This dish holds up beautifully for healthy weekly meal prep. Store leftovers in an airtight glass container in the refrigerator for up to 3 to 4 days. Reheat gently in a skillet over medium heat with a splash of chicken broth or water to refresh the glossy sauce texture.
