This is a weeknight stir-fry built around boneless chicken thighs, fermented black bean paste, snap peas, and bell pepper — all done in 35 minutes. The honest reason to make it: the black bean and oyster sauce combo produces a deeply savory, glossy coating that tastes like it took far longer than it did. It also lands as a complete meal straight from the wok.
The short version of why this works
Two things carry this dish. First, the cornstarch in the marinade — it coats the chicken pieces and sets into a thin, protective layer during the high-heat cook, which keeps the thighs juicy instead of rubbery. Second, the sequencing of the aromatics: garlic goes in before the black bean paste, not with it. Garlic burns fast at wok temperatures, so a quick 30-second head start lets it bloom without turning bitter, and then the paste goes in right behind it to mellow slightly in the hot oil before the vegetables hit the pan. Get those two things right and the rest of the recipe takes care of itself.
Troubleshooting
- Chicken steams instead of searing: The wok wasn’t hot enough before the chicken went in, or the pieces were crowded. Work in two batches if your wok is under 12 inches — a single layer browns, a pile steams.
- Sauce is watery and won’t cling: The chicken stock was added before the wok had a chance to reduce anything. Let the stock simmer for 30–45 seconds after adding it, stirring constantly, before returning the chicken. The residual cornstarch from the marinade will tighten it.
- Black bean paste tastes overwhelmingly salty: Brands vary a lot in salt level. Taste your paste before cooking — if it’s very salty, cut the soy sauce in the marinade to 1 tablespoon and skip any added salt elsewhere.
- Snap peas turn dull and limp: They went in too early or the heat dropped when the cold vegetables hit the pan. Add them after the peppers have had 60 seconds, keep the heat on high, and don’t stop tossing.
- Chicken isn’t cooked through after 4–5 minutes: Your pieces were cut larger than 1 inch, or the wok lost heat mid-cook. Check with an instant-read thermometer — poultry needs to hit 165°F (74°C) internally before it comes off the heat, no exceptions.
Make-ahead notes
The chicken can marinate in the fridge for up to 8 hours — longer than that and the cornstarch starts breaking down the texture. The fully cooked dish keeps well in an airtight container for up to 3 days; skip the green onion garnish until you reheat. To reheat, use a hot skillet or wok with a splash of water or chicken stock (about 2 tablespoons) and stir constantly for 2–3 minutes — the microwave works but softens the vegetables noticeably. This dish doesn’t freeze well; the snap peas turn mushy and the sauce separates on thawing.

Ingredients
Marinade and Chicken
- 500 grams boneless chicken thighs cut into 1-inch pieces
- 2 tablespoons soy sauce light soy sauce preferred
- 1 tablespoon cornstarch
- 1 ½ tablespoons rice wine Shaoxing wine, or dry sherry
Stir-Fry
- 2 tablespoons vegetable oil divided
- 3 cloves garlic minced
- 1 tablespoon fermented black bean paste found in Asian grocery stores
- 1 cup green pepper sliced, any color
- 1 cup snap peas strings removed
- 2 tablespoons oyster sauce
- 1 teaspoon sugar
- ½ cup chicken stock low-sodium, or water
Garnish
- 2 tablespoons green onions sliced, for garnish
Instructions
- Marinate the chicken. In a medium bowl, combine chicken pieces, soy sauce, cornstarch, and rice wine. Stir to coat thoroughly and allow to marinate for at least 15 minutes to tenderize and infuse flavor.
- Prepare the stir-fry. Heat 1 tablespoon of vegetable oil in a large wok over high heat. Once the oil is shimmering, add the marinated chicken. Stir-fry for about 4-5 minutes, or until the chicken turns golden brown on the outside, yet remains juicy within. Remove and set aside.
- Aromatic base. In the same wok, add the remaining tablespoon of vegetable oil. Add minced garlic and stir quickly for 30 seconds until fragrant, but not burnt. Introduce the black bean paste, gently stirring for a further 30 seconds to release its bold, aromatic elements.
- Combine vegetables and chicken. Add bell peppers and snap peas, tossing continuously with the aromatic mixture for 2-3 minutes until the vegetables are tender-crisp and vibrant in color. Return the chicken to the wok, mixing everything vigorously.
- Finishing touch. Stir in oyster sauce, sugar, and chicken stock, ensuring all ingredients are coated well and the sauce evenly distributed. Allow to simmer for a further 2 minutes, melding flavors into a harmonious blend. Remove from heat and garnish with sliced green onions before serving.

Frequently asked questions
Can I use chicken breast instead of thighs?
You can, but expect a drier result. Breast meat has less fat and cooks faster, so cut pieces slightly smaller than 1 inch and pull them from the wok the moment they hit 165°F (74°C) internally — even 30 seconds of overcooking makes breast meat chalky in a stir-fry.
Where do I find fermented black bean paste, and is there a substitute?
Most Asian grocery stores carry it near the sauces and condiments — look for labels that say ‘black bean sauce,’ ‘black bean garlic sauce,’ or ‘douchi paste.’ In a pinch, a tablespoon of miso paste plus a teaspoon of soy sauce gets you some of the fermented depth, though the flavor won’t be identical.
Do I need a wok, or will a regular pan work?
A large, heavy skillet works — skip the egg in the marinade mix if you’re tempted to add one, it makes the coating gummy in a flat pan. The main thing you lose without a wok is the high curved walls that let you toss everything without losing pieces over the side; a 12-inch cast iron or stainless pan on the highest heat your stove allows is a solid substitute.
