How to Make Spicy Jalapeño Chicken

Follow these simple steps to prepare this delicious Spicy Jalapeño Chicken:

Step 1: Prepare the Chicken
In a large mixing bowl, combine the chicken pieces, cornstarch, salt, and pepper. Toss the chicken until it’s evenly coated. This will ensure a crispy texture once cooked.

Step 2: Mix the Sauce
In another medium mixing bowl, whisk together the water, soy sauce, brown sugar, sesame oil, and minced garlic until well combined. Set it aside as we prepare the chicken.

Step 3: Cook the Chicken
Heat the olive oil in a large nonstick skillet over medium-high heat. When the oil is shimmering, carefully add the chicken to the hot oil. Sauté for about 2-3 minutes per side or until the chicken is golden brown and reaches an internal temperature of 165°F. Transfer the chicken to a plate and cover it lightly to keep warm.

Step 4: Sauté Onions and Jalapeños
In the same skillet, add the diced onion and sliced jalapeños. Cook for about 4-6 minutes until they are softened and fragrant. This stage will fill your kitchen with an irresistible aroma!

Step 5: Combine Everything
Return the chicken to the skillet, and pour in the prepared soy sauce mixture. Stir everything to combine well and allow it to cook for another 2-3 minutes, letting the flavors meld beautifully.

Step 6: Serve and Enjoy
Spoon the spicy jalapeño chicken over fluffy cooked white rice. Garnish with a sprinkle of sesame seeds for an extra touch of flair. Serve hot and watch your guests marvel at your culinary prowess!
