Step-by-Step Instructions

1. Make the Marinade: In a medium bowl, whisk together the gochujang, soy sauce, brown sugar, sesame oil, rice vinegar, garlic, ginger, and red pepper flakes (if using) until smooth .
2. Prep and Marinate the Chicken: Pat the chicken breasts completely dry with paper towels. For even cooking, you can gently pound them to an even ½-inch thickness . Place the chicken in a large bowl or zip-top bag. Pour the marinade over the chicken, ensuring each piece is well coated. Reserve about ¼ cup of the marinade in a separate small bowl for basting later . Cover and refrigerate for at least 1 hour, or up to 4 hours for deeper flavor .
3. Fire Up the Grill: Preheat your grill to medium-high heat (around 400°F). For a charcoal grill, set up a two-zone fire. For a gas grill, preheat all burners. Clean and oil the grates to prevent sticking.
4. Grill the Chicken: Remove the chicken from the marinade, letting any excess drip off. Place the chicken breasts on the grill. Cook for 5-6 minutes per side, until you get nice, golden-brown grill marks and the chicken is cooked through . During the last few minutes of cooking, brush the chicken with the reserved marinade to build up that sticky, flavorful glaze . The chicken is done when it reaches an internal temperature of 165°F.
5. Rest and Serve: Remove the chicken from the grill and let it rest on a cutting board for 5-10 minutes. This allows the juices to redistribute. Slice the chicken breasts and serve over steamed rice, or as part of a lettuce wrap with fresh veggies. Garnish with toasted sesame seeds and sliced green onions.

Tips for Korean BBQ Chicken Perfection

• Gochujang is Key: Gochujang is the soul of this dish, providing a unique sweet, savory, and spicy flavor that you can’t replicate . It’s widely available in the international aisle of most supermarkets.
• Don’t Skip the Rest: Marinating the chicken for at least an hour is crucial for the flavors to penetrate the meat. Overnight is even better !
• Watch the Sugar: The sugar in the marinade can burn quickly. Apply the reserved marinade for basting only during the final minutes of grilling to prevent burning and achieve a beautiful caramelized finish .
• Pound for Even Cooking: If your chicken breasts are thick, pounding them to a uniform thickness ensures they cook evenly and stay juicy .
• Serve it the Korean Way: For an authentic experience, serve the chicken with steamed rice, lettuce leaves, and a side of kimchi. The lettuce wraps, known as “ssam,” are a fun and delicious way to enjoy the meal .

Delicious Variations

• Smoked Korean Chicken: Smoke the chicken on a pellet grill at 225°F for about 45 minutes, then finish over high heat to crisp up the glaze.
• Less Spicy: Reduce or omit the red pepper flakes. For a milder, more kid-friendly version, you can also reduce the gochujang to 2 tablespoons and add a little extra brown sugar.
• Chicken Thighs: Boneless, skinless chicken thighs are a great substitute for breasts and are more forgiving on the grill, staying extra juicy .
• Korean BBQ Chicken Bowls: Serve the sliced chicken over a bed of rice with shredded carrots, cucumbers, and a drizzle of spicy mayo.

Storage and Reheating Instructions

Storage: Store leftover chicken in an airtight container in the refrigerator for up to 3-4 days.

Reheating: The best way to reheat this chicken is on the grill or in a skillet over medium heat for a few minutes per side to restore the crispy, caramelized exterior. You can also use a toaster oven or air fryer. Avoid microwaving, as it can make the chicken tough and the glaze gummy.

Freezing: The cooked chicken can be frozen for up to 2 months. Thaw in the refrigerator overnight before reheating.
