- Uses simple, accessible ingredients: Everything on the list is likely in your pantry or easily found at any supermarket, so there’s no hunting for obscure items.
Ingredients You’ll Need
- 500g boneless, skinless chicken thighs, cut into bite-sized pieces
- 2 tablespoons vegetable oil (or any neutral oil with a high smoke point)
- 8 cloves garlic, finely minced (about 2 tablespoons)
- 2–3 fresh red chilies, thinly sliced (seeds in for more heat, removed for less)
- 1 tablespoon dried red chili flakes (adjust to taste)
- 1 red bell pepper, sliced into thin strips
- 1 green bell pepper, sliced into thin strips
- 1 medium onion, halved and thinly sliced
- 3 tablespoons soy sauce (or tamari for gluten-free)
- 1 tablespoon oyster sauce (or mushroom sauce for vegetarian)
- 1 teaspoon brown sugar
- 1 teaspoon cornflour mixed with 2 tablespoons cold water (slurry)
- 2 spring onions, sliced diagonally for garnish
- 1 teaspoon sesame oil (optional, for finishing)
- Steamed jasmine rice, to serve
Tip: For the best texture, use chicken thighs rather than breast—they stay juicy and tender even under high heat, and they soak up the sauce beautifully.
How to Make Spicy Garlic Chili Chicken Stir-Fry
- Prepare the chicken and sauce: Pat the chicken pieces dry with kitchen paper—this is crucial for a good sear. In a small bowl, whisk together the soy sauce, oyster sauce, and brown sugar until the sugar dissolves. Set the sauce aside. The chicken should feel dry to the touch and look matte, not shiny.
- Heat the wok or pan: Place a large wok or a heavy-bottomed frying pan over high heat for a full 2 minutes. Add the vegetable oil and swirl to coat. The oil should shimmer and a drop of water flicked in should sizzle instantly. You want the pan screaming hot to create that coveted wok hei (breath of the wok).
- Sear the chicken: Add the chicken pieces in a single layer—do not overcrowd. Let them cook undisturbed for 2 minutes. The undersides should become a deep golden brown and release easily from the pan. Toss and cook for another 2 minutes until the chicken is cooked through and feels firm to the touch, with no pink remaining.
- Build the aromatics: Push the chicken to one side of the wok. Add the minced garlic, fresh chilies, and dried chili flakes to the empty space. Stir constantly for 30 seconds. The garlic should turn fragrant and just start to colour—you’ll smell a sharp, nutty aroma, and the dried flakes will deepen in colour to a dark brick red.
- Add the vegetables: Toss in the sliced bell peppers and onion. Stir-fry for 2–3 minutes. The peppers should brighten in colour and begin to soften at the edges, while the onion turns translucent. You’ll hear a lively hiss as the vegetables hit the hot pan.
- Pour in the sauce: Give the prepared sauce a quick stir, then pour it over the chicken and vegetables. Toss everything together to coat evenly. The sauce will bubble immediately and reduce slightly, clinging to the ingredients. Cook for 1 minute, until the sauce looks glossy and coats the back of a spoon.
- Thicken the sauce: Give the cornflour slurry a stir, then drizzle it into the pan while tossing continuously. Cook for another 30 seconds. The sauce will transform from a thin liquid to a silky, velvety glaze—you’ll see it cling to the chicken and vegetables, thickening without becoming gluey.
- Finish and serve: Remove the wok from the heat. Drizzle with sesame oil, if using, and toss once more. Garnish with sliced spring onions. Serve immediately over steamed jasmine rice. The dish should be steaming hot, the sauce shimmering, and the aroma of garlic and chili filling your kitchen.
Tips From My Kitchen
- Dry the chicken thoroughly: Excess moisture on the chicken prevents browning. Pat each piece dry with kitchen paper before cooking. Wet chicken steams rather than sears, resulting in a pale, rubbery texture instead of that golden, flavourful crust.
- Cut ingredients uniformly: Slice the chicken, peppers, and onion into similar-sized pieces. This ensures everything cooks at the same rate—you won’t end up with burnt garlic and raw peppers. Aim for bite-sized chunks about 2–3 cm across.
- Use a high smoke point oil: Vegetable, peanut, or avocado oil are ideal. Olive oil burns at high temperatures, giving the dish a bitter, acrid taste. The smoke point matters because stir-frying requires intense heat to develop flavour quickly.
- Prep everything before you start: Stir-frying moves fast—there’s no time to chop an onion while garlic is burning. Have all ingredients measured, sliced, and within arm’s reach. This is called mise en place, and it’s the secret to stress-free cooking.
- Don’t skip the cornflour slurry: The slurry gives the sauce body and helps it cling to the chicken and vegetables. Whisk the cornflour with cold water until completely smooth before adding—lumps will result in a clumpy sauce. The slurry should look like milky water with no visible white specks.
- Let the pan get screaming hot: A hot pan is non-negotiable. If you add ingredients before the oil shimmers, they’ll stew in their own juices. Wait until you see faint wisps of smoke rising from the oil—that’s your signal to start cooking.
Common Mistakes to Avoid
- Overcrowding the pan: Adding too much chicken at once drops the pan’s temperature, causing the meat to steam instead of sear. Cook in batches if necessary—the chicken should have space between pieces. You’ll know it’s overcrowded if the pan releases a lot of liquid and the chicken looks grey rather than golden.
- Wrong temperature: Stir-frying demands high heat throughout. Medium heat will not produce the same caramelisation or texture. Keep the burner on its highest setting, and if using an electric hob, give it time to recover between batches. The oil should sizzle fiercely every time you add ingredients.
- Skipping the rest time: While this dish is served immediately, if you’re making it ahead for meal prep, allow it to cool completely before refrigerating. This prevents condensation from diluting the sauce. When reheating, use a hot pan again—not a microwave—to restore the original texture.
Delicious Variations to Try
- Spicy Version: For those who love serious heat, add 1–2 teaspoons of gochujang (Korean chili paste) to the sauce, or toss in a handful of dried bird’s eye chilies along with the fresh ones. The sauce will take on a deeper red hue and a lingering, complex warmth.
- Vegetarian/Vegan Option: Swap the chicken for 400g of extra-firm tofu, pressed and cubed, or use a medley of mushrooms like shiitake and oyster. Replace oyster sauce with mushroom sauce or a splash of dark soy sauce. The cooking time for tofu is similar—just ensure it’s golden and crisp on all sides.
- Different Protein: This recipe works beautifully with beef sirloin (sliced against the grain), large peeled prawns, or even strips of turkey breast. Adjust cooking times accordingly: prawns need only 2–3 minutes total, while beef benefits from a quick sear and a minute less in the pan.
What to Serve With Spicy Garlic Chili Chicken Stir-Fry
- Steamed jasmine rice or fragrant basmati rice—it soaks up the sauce perfectly.
- A side of stir-fried greens like bok choy or Chinese broccoli, simply dressed with garlic and a splash of soy sauce.
- For a lighter meal, serve over cauliflower rice or alongside a crisp cucumber salad with rice vinegar and sesame seeds.
- If you’re in the mood for something more substantial, pair it with our Spicy Chicken Fajita Rice Bowl Recipe for a fusion feast that brings together smoky and spicy flavours.
- For a complete spread, start with our Crispy Falafel Wrap Tahini Sauce as an appetiser—the creamy tahini offers a cooling contrast to the chili heat.
Frequently Asked Questions
Can I make this dish ahead of time?
Yes, this stir-fry stores well in the refrigerator for up to 3 days in an airtight container. The flavours actually meld and deepen overnight. When reheating, use a hot wok or frying pan to revive the texture—avoid microwaving, which can make the chicken rubbery and the sauce watery.
How do I reduce the spiciness without losing flavour?
Start by removing the seeds and membranes from the fresh chilies, as these contain most of the heat. You can also reduce the dried chili flakes to 1 teaspoon or omit them entirely, relying solely on the garlic and fresh chilies for a milder, aromatic profile. A spoonful of yogurt or coconut milk served on the side can also tame the heat.
What’s the best substitute for oyster sauce?
For a vegetarian or vegan version, mushroom sauce is an excellent substitute—it has a similar umami richness and dark colour. Alternatively, you can use hoisin sauce for a sweeter profile, or simply double the soy sauce and add a teaspoon of brown sugar for balance.
Can I use chicken breast instead of thighs?
Absolutely, but be mindful of cooking time. Chicken breast cooks faster and can dry out if overdone. Slice it into even, thin strips and cook for about 3–4 minutes total, just until it turns opaque and springs back lightly when pressed. The key is to avoid overcooking, as breast meat has less fat to keep it moist.
What if I don’t have a wok?
A large, heavy-bottomed frying pan or a cast-iron skillet works perfectly. The important factor is the surface area and heat retention—you need enough room to spread ingredients without overcrowding. Preheat the pan thoroughly over high heat, and follow the same steps; the results will be nearly identical.
