Ingredients
- 1.5 lbs boneless, skinless chicken thighs or breasts, cut into 1-inch pieces
- 1/2 cup cornstarch
- 1/2 tsp salt
- 1/2 tsp black pepper
- 2 tbsp avocado or vegetable oil (divided)
- 2 large jalapeños, sliced into rings (leave seeds in for extra heat)
- 1/4 cup low-sodium soy sauce
- 1/4 cup water
- 2 tbsp brown sugar
- 4 cloves garlic, minced
- 1/2 yellow onion, diced (optional)
- 1 tsp sesame oil (optional, for extra flavor)
- Fresh cilantro or sesame seeds for garnish
- Cooked white rice, for serving
Step-by-Step Instructions

Step 1: Prep the Chicken
- Pat the chicken pieces dry with a paper towel.
- In a large bowl, mix cornstarch, salt, and pepper.
- Add chicken and toss until every piece is well coated. This coating gives the chicken its signature crispy texture135.
CookWithKushal Tip:
Always pat the chicken dry before coating. This ensures maximum crispiness when frying.
Step 2: Sear the Jalapeños
- Heat 1 tbsp oil in a large skillet over medium-high heat.
- Add sliced jalapeños and sauté for 1-2 minutes until fragrant.
- Remove jalapeños with a slotted spoon and set aside5.
CookWithKushal Tip:
Searing jalapeños first mellows their raw heat and infuses the oil with spicy flavor.
Step 3: Fry the Chicken
- Add the remaining oil to the skillet.
- Fry the coated chicken in batches, making sure not to overcrowd the pan.
- Cook for about 5-6 minutes, turning to brown all sides, until chicken is golden and cooked through (internal temperature should reach 165°F)135.
- Remove chicken and set aside.
CookWithKushal Tip:
Fry in batches for even browning. Overcrowding the pan steams the chicken instead of crisping it.
Step 4: Make the Sauce
- In a small bowl, whisk together soy sauce, water, brown sugar, and minced garlic.
- Optional: Add 1 tsp sesame oil for a nutty aroma35.
Step 5: Sauté Aromatics & Combine
- In the same skillet (add a little oil if needed), sauté diced onion for 2-3 minutes until soft.
- Return the chicken and jalapeños to the pan.
- Pour in the sauce and toss to coat everything evenly.
- Simmer on medium heat for 2-3 minutes, stirring, until the sauce thickens and glazes the chicken135.
CookWithKushal Tip:
Don’t rush the simmer—let the sauce reduce until it’s sticky and coats the chicken for maximum flavor.
Step 6: Garnish & Serve
- Remove from heat.
- Garnish with chopped cilantro or sesame seeds.
- Serve hot over steamed rice.
Chef CookWithKushal’s Pro Tips
- Heat Level: For extra spice, leave jalapeño seeds in or add a pinch of red pepper flakes to the sauce.
- Chicken Choice: Thighs stay juicier, but breasts work for a leaner option.
- Batch Frying: Always fry in small batches for the crispiest results.
- Make-Ahead: Prep chicken and sauce ahead; fry chicken just before serving for best texture.
- Serving Ideas: Try with fried rice or steamed veggies for a complete meal.
