First Step: PREPARE THE CHICKEN

1. Season the Chicken: Start by seasoning the chicken breasts (or thighs) with salt and freshly cracked black pepper on both sides. The pepper is a key ingredient here, so don’t be shy about adding a good amount.
2. Cook the Chicken: Heat 2 tablespoons of vegetable oil in a large skillet over medium-high heat. Once the oil is hot, add the chicken pieces and cook for about 6-7 minutes per side, until the chicken is golden brown and cooked through. The internal temperature of the chicken should reach 165°F (74°C).
3. Rest the Chicken: Once the chicken is cooked, remove it from the skillet and let it rest for a few minutes. This allows the juices to redistribute and keeps the chicken moist.

Second Step: PREPARE THE BLACK PEPPER SAUCE

1. Sauté the Aromatics: In the same skillet where you cooked the chicken, add 2 tablespoons of vegetable oil. Heat over medium heat and sauté the thinly sliced onion for 2-3 minutes, or until it becomes translucent and soft.
2. Add the Garlic and Ginger: Add the minced garlic and grated ginger to the skillet and cook for an additional 1-2 minutes, stirring frequently. The goal is to cook the garlic and ginger until fragrant but not burnt.
3. Crush the Black Pepper: In a small bowl, crush the black peppercorns with a mortar and pestle or a spice grinder. You want the pepper to be coarsely ground to give the sauce that signature kick. Add the crushed black pepper to the skillet with the aromatics, and cook for an additional 1 minute to release its fragrance.
4. Add the Sauces and Sugar: Stir in the soy sauce, oyster sauce, rice vinegar, and sugar. Mix well to combine all the ingredients.
5. Add the Chicken Broth: Pour in the chicken broth and bring the sauce to a simmer. Allow it to cook for about 5 minutes, letting the flavors meld together.
6. Thicken the Sauce: In a small bowl, mix the cornstarch with the water to form a slurry. Gradually pour the slurry into the simmering sauce while stirring continuously. This will help thicken the sauce to a glossy, smooth consistency. Let the sauce simmer for another 1-2 minutes until it reaches your desired thickness.

Third Step: Combine the Chicken with the Sauce

1. Slice the Chicken: Once the chicken has rested, slice it into thin strips against the grain. This will help make the chicken more tender and allow it to absorb the sauce better.
2. Add the Chicken to the Sauce: Return the sliced chicken to the skillet with the black pepper sauce. Toss to coat the chicken evenly with the sauce, allowing it to absorb all the flavors. Cook for an additional 2-3 minutes, ensuring the chicken is heated through and coated with the thickened sauce.
3. Final Adjustments: Taste the sauce and adjust the seasoning if needed. You can add a bit more soy sauce for saltiness, vinegar for tanginess, or black pepper for extra heat.

Final Step: Garnish and Serve

1. Garnish the Dish: Transfer the black pepper chicken to a serving plate and garnish with chopped green onions, toasted sesame seeds, and additional black pepper for a fresh kick.
2. Serve: This dish pairs perfectly with steamed jasmine rice or fried rice, which will help balance the spiciness of the black pepper sauce. You can also serve it with a side of sautéed vegetables or a simple salad to complete the meal.
