Quick Answer

First, defrost and heat the chicken breast according to the package instructions. If suitable for a frying pan, you can sear both sides over medium heat until the surface is slightly browned. Then, stir-fry onions, minced garlic, and black pepper in butter until fragrant. Add a small amount of oyster sauce, Worcestershire sauce, light soy sauce, and water to simmer into a thick sauce. Finally, return the chicken breast to the pan to absorb the onion and black pepper aroma. If the product label indicates it needs to be cooked, ensure the internal temperature reaches at least 75°C using a food thermometer before consumption.

Ingredients

• Black pepper cooked chicken breast 3 pieces (adjust according to actual package quantity)
• Onion 1 piece
• Minced garlic 2 teaspoons
• Coarse black pepper flakes 1 to 1.5 tablespoons
• Butter 15g
• Oyster sauce 1 teaspoon
• Worcestershire sauce 1 teaspoon
• Light soy sauce 1 teaspoon
• Sugar 1/2 teaspoon
• Water 100ml
• Cornflour 1 teaspoon
• Water 1 tablespoon (for slurry)
• Cooking oil 1 teaspoon

Method

1. First, prepare the chicken breast according to the package

   Do not assume it is ready-to-eat or does not need defrosting based solely on the product name. Follow the defrosting and heating methods on the package. Generally, frozen meat can be defrosted in a refrigerator at 4°C or below. If defrosting quickly with running cold water or a microwave, it should be cooked immediately. After defrosting, pat the surface dry with kitchen paper.

2. Slice the onion and prepare the black pepper sauce

   Slice the onion into coarse strips. Mix oyster sauce, Worcestershire sauce, light soy sauce, sugar, and 100ml of water. Separately, mix cornflour with 1 tablespoon of water to make a thin slurry. Since the chicken breast is already seasoned with black pepper and other flavours, the sauce base intentionally uses less soy sauce and sugar to avoid the final dish being too salty.

3. Sear the chicken breast first for browned aroma

   Preheat a frying pan over medium heat, add cooking oil, and place the chicken breast. Sear for about 2 to 3 minutes on each side until the surface is slightly browned and the whole piece is heated through. If the package instructions for heating time or method differ, the package must be followed. If the product is chicken that needs to be thoroughly cooked, the thickest part should reach 75°C or above. Remove and set aside.

4. Stir-fry onions until translucent

   In the same pan, turn to medium heat, add butter, and stir-fry the onions for about 3 minutes. Stir-fry until the onions turn from white to translucent with edges starting to turn a light golden colour. Then add minced garlic and stir-fry for about 30 seconds to release the aroma, but do not burn the garlic.

5. Stir-fry to release black pepper wok aroma

   Add coarse black pepper flakes and stir-fry over medium-low heat for about 30 to 45 seconds, allowing the black pepper to release its aroma in the butter and onion oils. Do not stir-fry over high heat for a long time, as black pepper can easily become bitter. This step is key to transforming ordinary sauced chicken breast into Cantonese black pepper chicken cutlet flavour.

6. Simmer and reduce the sauce

   Pour in the pre-mixed oyster sauce, Worcestershire sauce, and light soy sauce mixture. Simmer over medium heat until it begins to boil, then reduce to medium-low heat and simmer for about 2 minutes. Add the cornflour slurry, stirring as you pour, and cook for about 30 to 60 seconds until the sauce thickens to a consistency that coats the back of a spatula.

7. Return chicken breast to pan to absorb sauce

   Return the chicken breast to the pan and turn and move it over medium-low heat for about 1 to 2 minutes, allowing the black pepper onion sauce to evenly coat the surface. If the sauce is too thick, add 1 to 2 tablespoons of water to adjust. If the product needs to be thoroughly cooked, ensure the chicken centre reaches at least 75°C at the end. Plate and pour the onions and thick sauce over the chicken breast. Serve hot with white rice.

Frequently Asked Questions

Can black pepper chicken breast be cooked directly using this method?

Yes, but the first step must be to check the package's defrosting and heating instructions. Since this ingredient is already flavoured with black pepper, there is no need to marinate it again with a large amount of black pepper. After searing, returning it to the pan with the onion black pepper sauce will result in a more complete flavour.

Why sear the chicken breast before cooking the black pepper sauce?

The focus of Cantonese black pepper chicken cutlet is the seared aroma on the surface of the chicken and the rich sauce base formed by stir-frying onions, minced garlic, and black pepper. Searing the chicken breast first prevents the chicken from being simmered in a large amount of sauce from the start, making it easier to retain the surface browned aroma.

Can sugar be omitted from the black pepper sauce?

Yes. Since the pre-seasoned chicken breast already has flavour, sugar is used in small amounts to balance the savouriness of oyster sauce, Worcestershire sauce, and black pepper. If you prefer a lighter taste, it can be completely omitted, using the natural sweetness of the onions to balance the sauce base.

How do you know if the chicken breast is safely cooked through?

Do not rely solely on the colour of the meat. The Food Safety Centre of Hong Kong recommends using a food thermometer to measure the thickest part of the meat, ensuring the centre temperature reaches at least 75°C. If you do not have a thermometer, heat thoroughly until the juices run clear and there is no pink when cut open.
