Inch pieces of chicken thigh tossed with soy, rice vinegar, cornstarch, cracked pepper and salt, left ten minutes while the sauce and vegetables are prepped.
The chicken sears in two batches, onion and bell pepper follow with garlic and ginger, and a whisked broth-and-oyster-sauce mixture goes in to thicken around everything before sesame oil finishes it.
Why This Recipe Works
- Thighs rather than breast. They stay tender through a hard sear and a second turn in the pan, which is exactly what this method asks of them.
- The marinade contains cornstarch, so it is doing two things at once: seasoning the meat and giving it a coating that browns. It is why ten minutes is enough.
- The sauce is whisked before the pan is even hot, and whisked again before it goes in. Cornstarch drops out of suspension while it stands, and a sauce poured off the top of a settled cup will not thicken.
- Two batches of chicken, and the reason is the same as any stir-fry: a wok that has been cooled by too much cold meat browns nothing.
- Garlic and ginger get thirty seconds and go in after the vegetables, not before. Minced aromatics in a hot pan for two or three minutes would be bitter by the time the peppers were ready.
- Sesame oil at the very end. It is toasted, so its flavour is volatile — added earlier it cooks off, and the recipe treats it as a seasoning rather than a fat.
Where Each Layer Of Pepper Goes
The dish is named for one ingredient that appears three separate times, in three different forms. Following where each goes explains why it tastes of pepper rather than merely containing it.
The marinade
10 minutes, while you prep everything else1 tbsp soy sauce, rice vinegar, 1 tbsp cornstarch, 1 tsp freshly cracked black pepper, 1/2 tsp kosher salt
Cracked pepper gets ten minutes directly against the meat, and the cornstarch here is a coating — it is what gives the seared thigh its surface.
The sauce
Whisked until smooth before the pan is hotChicken broth, oyster sauce, 1 tbsp soy sauce, dark soy if using, 2 tsp coarsely ground black pepper, brown sugar, 1 tsp cornstarch
Coarsely ground pepper suspended in liquid — a rounder heat than the cracked pepper on the meat. The teaspoon of cornstarch here is a thickener, not a coating.
The aromatics
2–3 minutes, then 30 secondsOnion, green bell pepper, optional celery, then garlic and ginger
Vegetables first for two to three minutes until crisp-tender, garlic and ginger only for the last thirty seconds so they perfume rather than scorch.
The bind
1–2 minutes of constant tossingThe chicken and its juices, then the whisked sauce
Tossed constantly for a minute or two while the cornstarch does its work and the sauce goes from liquid to a coat on every piece.
The finish
Toasted sesame oil and a few extra cracks of black pepper
Both go in off the boil. Sesame oil is a flavouring rather than a cooking fat, and the last pepper is there to be tasted rather than cooked.
Then tasteThe recipe's own last instruction before serving: taste and adjust with more soy or pepper as desired.
How to Make It
Marinate the chicken
In a bowl, toss the chicken with 1 tbsp soy sauce, rice vinegar, 1 tbsp cornstarch, 1 tsp cracked black pepper and 1/2 tsp kosher salt. Let stand 10 minutes while you prep the sauce and vegetables.
Stir the sauce
In a measuring cup, whisk together the chicken broth, oyster sauce, 1 tbsp soy sauce, dark soy if using, 2 tsp coarsely ground black pepper, brown sugar and 1 tsp cornstarch until smooth.
Sear in two batches
Set a large skillet or wok over medium-high and add 1 tbsp oil. When shimmering, add half the chicken in a single layer and sear 2–3 minutes per side until browned and nearly cooked. Transfer to a plate; repeat with the remaining oil and chicken.
Vegetables, then aromatics
Add the onion, bell pepper and celery to the pan. Stir-fry 2–3 minutes until crisp-tender. Add the garlic and ginger; cook 30 seconds until fragrant.
Sauce it
Return the chicken and any juices to the pan. Whisk the sauce briefly and pour it in. Toss constantly for 1–2 minutes until the sauce thickens and coats the chicken.
Finish off the boil
Stir in the toasted sesame oil and a few extra cracks of black pepper. Taste and adjust the seasoning with more soy or pepper as desired.
Serve
Garnish with scallions and serve hot over steamed rice or noodles.
Ingredient Notes
- Boneless, skinless chicken thighs
- A pound and a half cut into inch pieces. Even sizing matters more here than usual — every piece gets the same two to three minutes a side.
- Cornstarch, in two places
- A tablespoon in the marinade as a coating, a teaspoon in the sauce as a thickener. The recipe lists them separately because they are not the same job.
- Black pepper, in three forms
- A teaspoon freshly cracked in the marinade, two teaspoons coarsely ground in the sauce, and more cracked over at the end. Coarse throughout — fine pepper would turn the sauce grey and muddy.
- Dark soy sauce (optional, for color)
- A teaspoon, and the recipe says what it is for. It deepens the colour without adding much salt, which is why it is optional.
- Oyster sauce
- A tablespoon and a half. It carries the savoury weight of the sauce; the brown sugar or honey is only there to balance it.
- Low-sodium soy sauce (or tamari for gluten-free)
- The recipe names tamari as the swap in both places soy appears, so the dish is straightforwardly gluten-free if you also use a gluten-free oyster sauce.
Success Tips
- Whisk the sauce again right before it goes in — cornstarch settles as it stands.
- Prep the vegetables during the ten-minute marinade, not before it.
- Let the first batch of chicken brown before you touch it.
- Keep tossing once the sauce is in; a cornstarch sauce catches the moment it stops moving.
- Save some cracked pepper for after the heat is off.
Serving Ideas
Steamed rice or noodles, as the recipe's last step says. Something plain is the right partner — the sauce is salty and peppery enough that a seasoned side would compete with it.
Storage and Reheating
Refrigerate
Refrigerate in an airtight container for up to 3 days. The cornstarch sauce sets firm when cold and loosens with heat.
Freeze
Freeze for up to 2 months. Cornstarch-thickened sauces can weep slightly on thawing; stir well while reheating.
Reheat
Reheat in a pan over medium with a splash of broth or water to bring the sauce back to a coating consistency.
Frequently Asked Questions
Can I use chicken breast?
The recipe specifies thighs. Breast in the same two-to-three-minutes-a-side sear and then a second turn in the sauce dries out where thigh does not.
Can this be made gluten-free?
The recipe already names tamari as the alternative wherever soy sauce appears. You would also need a gluten-free oyster sauce.
My sauce stayed thin.
It usually means the cornstarch settled in the cup and did not make it into the pan. The recipe says to whisk the sauce briefly before pouring for that reason.
Do I have to include the celery?
No — the recipe marks it optional. The onion and green bell pepper are the vegetables the dish is built on.
