Preparation Time and Servings
Prep Time: 15 minutes
Cook Time: 15 minutes
Total Time: 30 minutes
Servings: 4
Ingredients
For the Chicken
2 pounds boneless, skinless chicken thighs, trimmed and cut into 1-inch pieces
¼ cup cornstarch
¼ teaspoon kosher salt
2 tablespoons extra virgin olive oil
¼ teaspoon ground black pepper
For the Sauce
⅓ cup soy sauce
1 teaspoon sesame oil
⅓ cup water
2 teaspoons minced garlic
⅓ cup light brown sugar, packed
For the Stir-Fry
½ yellow onion, diced
2 large jalapeño peppers, thinly sliced into rounds
For Garnish
Sesame seeds, to taste
Cooked white rice, for serving
Step-by-Step Instructions
Step 1: Prepare the Chicken
Begin by preparing the chicken. In a large bowl, combine the chicken pieces, cornstarch, salt, and pepper. Toss everything together until the chicken is evenly coated. This simple coating adds a light crispness to the chicken as it cooks, while also helping the sauce stick later.
Step 2: Prepare the Sauce
In a medium bowl, whisk together the soy sauce, water, brown sugar, sesame oil, and minced garlic until the sugar dissolves. This sauce will provide the perfect balance of sweetness, saltiness, and aromatic flavors that elevate the entire dish. Set it aside for now.
Step 3: Cook the Chicken
Heat the olive oil in a large nonstick skillet over medium-high heat. Once the oil is shimmering, add the chicken pieces in a single layer, making sure not to overcrowd the skillet. Overcrowding can cause the chicken to steam rather than sear, so it’s best to cook in batches if needed.
Let the chicken sear for 2–3 minutes on each side until browned and cooked through. The internal temperature should reach 165°F (74°C) for safety. Once cooked, remove the chicken from the skillet and set it aside.
Step 4: Sauté the Vegetables
Using the same skillet, add the diced onion and sliced jalapeños. Sauté them for 4–6 minutes, stirring occasionally, until the onions become translucent and the jalapeños are slightly softened. The heat from the jalapeños will infuse the skillet, adding a bold, spicy aroma to the dish.
Step 5: Combine and Simmer
Return the cooked chicken to the skillet with the sautéed vegetables. Pour in the prepared sauce and give everything a good stir to combine. Let the mixture simmer for 2–3 minutes. As it cooks, the sauce will thicken slightly, coating the chicken and vegetables beautifully. This step ensures that every bite is packed with flavor.
Step 6: Serve
Serve the jalapeño chicken hot over a bed of cooked white rice. Garnish with sesame seeds for a touch of nuttiness and added texture.
Additional Tips
Adjust the spiciness to your liking by removing the seeds and membranes from the jalapeños for a milder flavor. If you love extra heat, consider adding another jalapeño or sprinkling in a pinch of red pepper flakes. To make this dish even more versatile, try adding your favorite vegetables such as bell peppers, snap peas, or broccoli. These additions not only enhance the nutritional value but also add vibrant color to the dish.
If you’re looking for a lighter preparation, you can cook the chicken in an air fryer. Preheat the air fryer to 400°F (200°C), place the coated chicken pieces in a single layer, and cook for about 10 minutes, flipping halfway through, until crispy and fully cooked.
Spicy Jalapeño Chicken Stir-Fry Variations
Vegetarian Option: Swap the chicken for tofu or cauliflower florets. Coat and prepare them the same way for a delicious meat-free alternative.
Low-Sodium Version: Replace regular soy sauce with reduced-sodium soy sauce to lower the overall salt content.
Add More Vegetables: Incorporate sliced bell peppers, snap peas, or mushrooms to create a more colorful and nutrient-packed stir-fry.
Different Protein: Replace the chicken thighs with shrimp, thinly sliced beef, or even pork strips for a different twist.
