Step-by-Step Instructions

1. Prepare the Chicken and Vegetables

• Cut the Chicken: Slice the chicken breast or thighs into bite-sized pieces. Ensure they are uniform in size for even cooking.
• Slice the Vegetables: Slice the mushrooms and zucchini into similar-sized pieces. Mince the garlic and grate the ginger.

2. Marinate the Chicken

• Combine Ingredients: In a mixing bowl, combine 1 tablespoon soy sauce, 1 tablespoon oyster sauce, 1 teaspoon cornstarch, and 1 teaspoon sesame oil. Add the chicken pieces and mix well.
• Marinate: Let the chicken marinate for at least 30 minutes to allow the flavors to penetrate.

3. Prepare the Sauce

• Mix Sauce Ingredients: In a separate bowl, combine 1/4 cup soy sauce, 2 tablespoons oyster sauce, 1 tablespoon hoisin sauce, and 1/2 cup chicken broth. Mix well.
• Make the Slurry: In a small bowl, mix 1 tablespoon cornstarch with 2 tablespoons water to create a slurry. This will help thicken the sauce later.

4. Cook the Chicken

• Heat the Wok: Preheat the wok or large skillet over medium-high heat. Add 1 tablespoon of vegetable oil and swirl to coat.
• Cook the Chicken: Add the marinated chicken to the wok in a single layer. Cook for about 3-4 minutes, or until the chicken is browned and cooked through. Remove the chicken from the wok and set it aside.

5. Cook the Vegetables

• Sauté Garlic and Ginger: In the same wok, add another tablespoon of vegetable oil if needed. Add the minced garlic and grated ginger, and sauté for about 30 seconds until fragrant.
• Add Mushrooms and Zucchini: Add the sliced mushrooms and zucchini to the wok. Stir-fry for about 4-5 minutes, or until the vegetables are tender but still crisp.

6. Combine and Finish the Dish

• Return Chicken to Wok: Add the cooked chicken back to the wok with the vegetables.
• Add Sauce: Pour the prepared sauce over the chicken and vegetables. Stir well to combine.
• Thicken the Sauce: Add the cornstarch slurry to the wok and stir continuously until the sauce thickens and coats the chicken and vegetables evenly. This should take about 1-2 minutes.
• Finish with Sesame Oil: Drizzle 1 teaspoon of sesame oil over the dish and give it a final stir.

7. Serve

• Plate the Dish: Transfer the mushroom chicken to a serving dish.
• Garnish: Garnish with chopped green onions and a sprinkle of red pepper flakes if desired.
• Accompaniments: Serve hot with steamed rice or noodles for a complete meal.
