Step-by-Step Instructions

1. Prepare the Gochujang Glaze: In a medium bowl, whisk together the gochujang, soy sauce, honey, sesame oil, minced garlic, grated ginger, rice vinegar, and brown sugar until you have a smooth, thick paste. This is your flavor-packed Korean BBQ glaze.
2. Marinate the Chicken: Pat the chicken dry with paper towels. Using your hands, gently loosen the skin over the breasts and thighs. Rub about half of the gochujang glaze directly onto the meat under the skin. Spread the remaining glaze all over the outside of the chicken and inside the cavity. For the best flavor, cover and refrigerate for at least 2 hours, or overnight.
3. Preheat Your Smoker or Grill: For a smoker, preheat it to 225-250°F. If using a charcoal grill, set it up for indirect heat by banking the hot coals to one side. For a gas grill, preheat to medium (around 350°F), then turn off the burner(s) on one side and add a smoker box or foil packet filled with soaked wood chips. Aim for a steady cooking temperature of 225-250°F for that low-and-slow magic.
4. Add Wood for Aroma: Once your smoker or grill is at the right temperature, add your wood chips or chunks. Applewood and cherry are fantastic choices for poultry, as they provide a mild, sweet smoke that complements the spicy-sweet glaze perfectly.
5. Smoke the Chicken: Place the chicken directly on the grill grate over the indirect heat zone, breast side up. Close the lid and smoke for approximately 2 to 2.5 hours. Maintain a consistent temperature and add more wood chips as needed for that continuous smoky flavor.
6. Glaze and Finish: During the last 30 minutes of cooking, brush the chicken with any reserved glaze to build a sticky, caramelized coating. The chicken is done when the internal temperature in the thickest part of the thigh reaches 165°F and the skin is deep mahogany brown and crispy.
7. Rest and Serve: Remove the chicken from the smoker and let it rest on a cutting board for 10-15 minutes. This crucial step allows the juices to redistribute, ensuring every bite is succulent. Garnish with toasted sesame seeds and chopped green onions before serving.

Essential Smoker and Grilling Tips

• Avoiding Dry Meat: Low and slow cooking is the key to juicy smoked chicken. Resist the urge to crank up the heat. Always use a reliable meat thermometer and pull the chicken off at 160°F, as it will rise to a safe 165°F while resting.
• Choosing the Right Wood: For Korean BBQ, fruitwoods like applewood or cherry are ideal. They add a delicate sweetness that balances the spicy gochujang. Hickory also works well if you prefer a stronger, more robust smoke flavor.
• Maintaining Temperature: Keep your smoker or grill temperature steady between 225-250°F. Too high, and the sugar in the glaze will burn before the chicken cooks through. Too low, and the skin won’t crisp up properly.
• Spatchcocking Option: For faster, more even cooking, you can spatchcock (butterfly) the chicken by removing the backbone and flattening it. This reduces smoking time to about 1.5 hours and gives you more crispy skin surface area.

Delicious Variations to Try

• Extra Spicy Version: Add 1-2 finely chopped fresh Thai bird’s eye chilies to the glaze for a serious heat boost.
• Sweet Soy Garlic Version: Replace gochujang with 1/2 cup more soy sauce, double the garlic, and add 2 tbsp of minced garlic for a savory, umami-packed twist.
• Healthy Version: Use skinless chicken breasts or thighs and reduce the honey to 2 tablespoons. The smoking process will still infuse incredible flavor without the added sugar.
• Smoky Mesquite Version: Swap the fruitwood for mesquite for a bolder, more intense smoky flavor that stands up to the spicy-sweet glaze.
• Citrus-Korean Fusion: Add the zest and juice of one orange to the glaze for a bright, tangy contrast to the rich, savory gochujang.

Storage and Reheating Instructions

Storing Leftovers: Remove the meat from the bones and store it in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the shredded or sliced smoked chicken for up to 2-3 months.

Reheating Without Drying: To maintain moisture, reheat the smoked chicken in the oven at 300°F. Place the meat in a baking dish with a splash of chicken broth, cover with foil, and heat for 10-15 minutes. You can also gently reheat it in a skillet over medium heat with a little bit of oil or butter.

Frequently Asked Questions (FAQ)

How long does it take to smoke a whole chicken at 225°F?

At 225°F, a 4-5 lb whole chicken typically takes about 2.5 to 3 hours. Always rely on the internal temperature reaching 165°F in the thickest part of the thigh rather than just the time, as every smoker and grill runs differently.

What type of wood is best for Korean BBQ smoked chicken?

Fruitwoods like applewood or cherry are excellent choices for this recipe. They provide a mild, sweet, and slightly fruity smoke that enhances the sweet-spicy gochujang glaze without overpowering it. Hickory is a great alternative if you prefer a stronger smoky flavor.

Can I make this recipe on a gas grill?

Absolutely! You can achieve great results on a gas grill by setting it up for indirect heat (turning off one burner). To get that smoky flavor, use a smoker box or create a foil packet filled with soaked wood chips, poking holes in it, and place it directly on the heat source.

What is gochujang and can I substitute it?

Gochujang is a fermented Korean chili paste that’s savory, spicy, and slightly sweet. It’s a key ingredient for authentic Korean flavor. If you can’t find it, you can substitute with a mix of red pepper flakes, miso paste, and a little sugar, but the flavor won’t be quite the same.

Why is my smoked chicken skin rubbery?

Rubbery skin often happens when the temperature isn’t high enough at the end of the cook to crisp the skin. To fix this, you can finish the chicken over direct heat for a few minutes on each side, or increase the smoker temperature to 350°F for the last 15-20 minutes to render the fat and crisp up the skin.
