Quick Pepper Chicken Stir Fry

The sizzle of chicken hitting a screaming hot wok is one of those sounds that instantly makes a kitchen feel alive, and this pepper chicken stir fry earns that soundtrack every single time.

My wok spent years gathering dust until a rainy Tuesday when takeout felt too sad and too slow, and this stir fry rescued the entire evening with nothing more than pantry staples and a bit of fire.

Ingredients

• 500 g boneless skinless chicken breast thinly sliced: Slice against the grain and slightly freeze the chicken first for paper thin even pieces that cook in a flash.
• 1 red bell pepper sliced: The sweetness balances the savory sauce beautifully, so do not skip this color.
• 1 yellow bell pepper sliced: Adds a mellow sweetness and bright visual contrast to the dish.
• 1 green bell pepper sliced: Brings a slight bitterness that rounds out the sweeter peppers perfectly.
• 1 small onion sliced: Any onion works but a sweet onion melts into the sauce in the most wonderful way.
• 2 garlic cloves minced: Fresh garlic only, and add it late so it never turns bitter.
• 2 spring onions sliced: Save these for the very end as a raw garnish that adds a fresh bite.
• 2 tbsp soy sauce: Use a good quality soy sauce and choose gluten free tamari if needed.
• 1 tbsp oyster sauce: This is the secret depth charge that makes everything taste restaurant quality.
• 1 tbsp hoisin sauce: A touch of sweetness and complexity that ties the whole sauce together.
• 1 tbsp rice vinegar: Balances the rich sauces with a gentle tang.
• 1 tsp freshly ground black pepper: Coarsely cracked is best since this dish wears pepper like a badge of honor.
• 1 tsp corn starch: Dissolve it fully in the sauce liquid before it hits the heat or you will get lumps.
• 60 ml water: Thins the sauce just enough to coat every strip of chicken and pepper.
• 1 tbsp sesame oil: Add this to the wok after the vegetable oil for a toasty aromatic base.
• 1 tbsp vegetable oil: Use a neutral oil with a high smoke point for the initial sear.

Instructions

Whisk the sauce together:

In a small bowl, combine the soy sauce, oyster sauce, hoisin, rice vinegar, black pepper, corn starch, and water, whisking until the corn starch disappears completely with no cloudy clumps at the bottom.

Get the wok ripping hot:

Heat the vegetable oil in a large wok or heavy skillet over high heat until you see the first wisps of smoke, because a properly hot pan is the difference between stir fry and stew.

Sear the chicken:

Spread the sliced chicken in a single layer and let it sit undisturbed for a minute before tossing, cooking three to four minutes total until golden and just cooked through, then transfer to a plate.

Toss the peppers and aromatics:

Add the sesame oil to the same wok, throw in the onion and all three bell peppers, and stir fry for two to three minutes until tender crisp with blistered edges, then add the garlic for thirty seconds until fragrant.

Bring it all home:

Return the chicken to the wok, pour in the sauce, and toss everything vigorously for two to three minutes until the sauce thickens into a glossy glaze that clings to every piece.

Garnish and serve:

Scatter the sliced spring onions over the top and serve immediately over steamed jasmine rice or noodles while the sauce is still bubbling and the peppers retain their snap.

The first time I served this to friends they assumed I had ordered in and simply plated it, which remains one of my proudest kitchen compliments.

Wok Wisdom for Beginners

A wok transforms this recipe but a large cast iron skillet works nearly as well if you let it get hot enough and resist the urge to stir constantly. The real magic happens when food meets metal and sits there long enough to char slightly, creating those deeply flavored spots that taste like a street market in Bangkok.

Swaps and Add Ins

Snap peas, broccoli florets, or julienned carrots slide right into this recipe without changing the cook time, and a pinch of chili flakes in the sauce turns up the heat for those who want it.

Getting the Sauce Right Every Time

The sauce should coat the back of a spoon like thin syrup when it is done, and if it looks too loose just let it bubble thirty seconds longer.

• Taste the sauce before adding it to the wok and adjust salt or vinegar as needed.
• Always have your rice or noodles ready before you start cooking because the stir fry waits for no one.
• Leftovers reheat beautifully in a dry skillet the next day for an even better lunch.

Save

Keep this one in your back pocket for those nights when hungry people are circling the kitchen and patience is thin. It never lets you down.

Recipe FAQs

→ How do I keep the chicken tender?

Slice the chicken thinly against the grain and cook over high heat just until opaque. Remove briefly while vegetables cook and return to finish; this prevents overcooking and keeps pieces juicy.

→ Can I swap the protein?

Yes. Thinly sliced pork or beef works well with the same technique; for plant-based options use firm tofu pressed and seared, adjusting cook time until browned on both sides.

→ What thickens the sauce?

Cornstarch added to the sauce creates a glossy, clingy finish. Mix it with water first, then add to the hot wok and stir until the sauce thickens—only a minute or two is needed.

→ How can I make this gluten-free?

Use gluten-free soy sauce or tamari and check hoisin and oyster sauce labels for gluten. Alternatively, substitute with coconut aminos and a splash of fish sauce for depth, if safe for diners.

→ What vegetables are good substitutes?

Snap peas, broccoli florets, thinly sliced carrots or zucchini can replace or complement bell peppers. Adjust stir-fry time so each vegetable stays tender-crisp.

→ How do I add more heat?

Stir in crushed chili flakes, sliced fresh chilies, or a spoonful of chili-garlic sauce when adding the garlic. Taste and add gradually to control the spice level.
