Ingredients

For the Chicken Marinade

• 500g chicken breasts, cut into bite-sized cubes
• ¼ tsp salt
• ¼ tsp black pepper
• 2 tsp soy sauce
• 1 large egg
• 2 tbsp cornflour (cornstarch)
• 2 tbsp plain flour (all-purpose flour)
• Oil, for frying

For the Black Pepper Sauce

• 3 tbsp soy sauce
• 1 ½ tbsp chilli sauce
• 1 tbsp oyster sauce
• ¼ tsp rice vinegar
• ¼ tsp sesame oil
• 2 tsp crushed black pepper (coarsely ground works best!)
• ¾ cup chicken broth
• 1 tsp cornstarch

For Cooking & Garnish

• 2 tbsp vegetable oil
• 1 tbsp ginger garlic paste
• 1 medium yellow onion, cut into bite-sized chunks
• 1 bell pepper, cut into bite-sized chunks
• Spring onion greens, finely sliced (for garnish)
• Steamed Jasmine or Basmati rice, for serving

Instructions

1. Marinate the Chicken

In a mixing bowl, combine the cubed chicken breasts with salt, black pepper, soy sauce, egg, cornflour, and plain flour. Mix thoroughly until every piece of chicken is evenly coated in a smooth, sticky batter. Set aside to marinate for 10 to 15 minutes.

2. Whisk the Black Pepper Sauce

In a measuring cup or small bowl, whisk together the soy sauce, chilli sauce, oyster sauce, rice vinegar, sesame oil, crushed black pepper, chicken broth, and 1 tsp cornstarch until smooth. Set aside.

3. Fry Until Crispy

Heat oil in a deep skillet or pan over medium-high heat. Fry the marinated chicken cubes in batches for 4 to 5 minutes until golden brown, crispy, and cooked through. Remove with a slotted spoon and drain on paper towels or a wire cooling rack.

4. Sauté Aromatics & Veggies

In a large skillet or wok over high heat, add 2 tablespoons of oil. Add the ginger garlic paste and sauté for 30 seconds until fragrant.

Add the chopped onions and bell peppers to the wok. Stir-fry over high heat for 1 to 2 minutes so they soften slightly while staying bright and crisp.

5. Sauce & Glaze

Give the prepared black pepper sauce a quick whisk to re-dissolve any settled cornstarch, then pour it directly into the hot wok with the vegetables.

Bring to a rapid simmer for 1 to 2 minutes until the sauce thickens into a glossy, dark glaze.

6. Toss & Serve

Add the fried crispy chicken cubes into the sauce. Toss rapidly over high heat for 1 minute until every piece is coated in the glossy black pepper glaze and heated through.

Remove from heat immediately. Garnish generously with sliced spring onion greens and serve hot over a bowl of steamed white rice!

The Secret to Great Black Pepper Sauce

For the absolute best flavor, use coarsely crushed black peppercorns rather than fine table black pepper! Coarsely ground pepper releases aromatic oils when cooked into the hot soy and oyster sauce base, giving you pockets of bold, spicy heat without making the sauce feel dusty or overly pungent.

Keeping the Vegetables Crisp

High-heat stir-frying is key! Stir-fry your onions and bell peppers for only 1 to 2 minutes before pouring in the sauce. This leaves them with a light blister on the outside while preserving their juicy crunch, creating the perfect contrast against the crispy fried chicken.

Tips for Getting It Right

• Fry in Batches: Avoid crowding the pan when frying the chicken so the oil temperature stays high and the coating crisps up properly.
• Whisk Before Pouring: Cornstarch naturally settles at the bottom of liquid mixtures, so give the sauce a quick stir right before adding it to the wok.
• Serve Right Away: Toss the crispy chicken into the hot sauce right before serving so the batter stays crunchy!

Storage and Reheating

• Storage: Store leftover stir-fry in an airtight container in the refrigerator for up to 2 days.
• Reheating: Reheat in a hot skillet or wok over medium-high heat for 2 to 3 minutes, or air fry the chicken separately to restore its crispiness before tossing back into the warmed sauce and veggies.

Frequently Asked Questions (FAQ)

Q. Can I use chicken thighs instead of breasts?

Yes! Boneless, skinless chicken thighs cut into bite-sized cubes work fantastically and stay extra juicy during frying.

Q. Can I air fry the chicken instead?

Yes! Spray the coated chicken pieces generously with oil spray and air fry at 200°C (390°F) for 10 to 12 minutes, shaking the basket halfway through until golden and crispy.

Q. How do I make it extra spicy?

Increase the crushed black pepper to 1 tablespoon or add sliced fresh red or green chillies alongside the onions and bell peppers!
