How to Make Korean Gochujang Roast Chicken
-
Whisk Together: In a mixing bowl, combine the Korean Gochujang paste, vegetable oil, oyster sauce, soy sauce, sugar, rice vinegar, mirin, sesame oil, minced garlic, and grated ginger. Whisk until well-blended and smooth.
-
Coat the Chicken: Place your whole chicken in a large zip-top bag or a bowl. Pour the marinade over the chicken, ensuring it’s fully coated. Seal the bag or cover the bowl and marinate it in the refrigerator for 8-16 hours, preferably overnight.
-
Prepare for Baking: About 30 minutes before baking, take the marinated chicken out of the fridge to bring it to room temperature. This helps with even cooking.
-
Preheat the Oven: Set your oven to preheat at 356°F (180°C) or 160°C for fan-assisted ovens. This ensures a perfect baking environment for our chicken.
-
Bake the Chicken: Place the chicken on a roasting pan. Bake uncovered for 30 minutes, and then cover with aluminum foil. Roast for another hour, or until the juices run clear when a knife is inserted into the thickest part.
-
Rest the Chicken: Once done, remove the chicken from the oven and let it rest for 15-20 minutes. This allows the juices to redistribute, keeping the meat moist and flavorful.
-
Optional: For an extra crispy skin, broil the chicken for 1-2 minutes after applying additional boiled-down marinade. Watch carefully to prevent burning!
Optional: Serve with a sprinkle of sesame seeds for an added touch of crunch.

Expert Tips for Korean Gochujang Roast Chicken
-
Marination Time: Opt for an overnight marination if possible; this ensures the flavors penetrate the chicken, creating a juicy, flavorful roast.
-
Room Temperature: Always bring the marinated chicken to room temperature before baking. This helps in cooking evenly and prevents dryness.
-
Covering the Chicken: Cover with aluminum foil after 30 minutes of baking to prevent over-browning. This helps retain moisture for a succulent Korean Gochujang roast chicken.
-
Check Doneness: Use a meat thermometer to ensure the chicken reaches 165°F (75°C) in the thickest part. This avoids undercooking or drying out the meat.
-
Broiling Tip: If you like a crispy skin, remember to broil for just 1-2 minutes at the end. Keep a close eye on it to prevent burning!

Korean Gochujang Roast Chicken Recipe FAQs
What type of chicken should I use for the best results?
For the best flavor and texture, I recommend using a whole chicken that weighs between 2-3 pounds. This size ensures that the meat remains juicy during baking while allowing the marinade to infuse thoroughly.
How do I know when the chicken is fully cooked?
To ensure your Korean Gochujang roast chicken reaches perfect doneness, use a meat thermometer. The internal temperature should read 165°F (75°C) in the thickest part of the thigh. If you don’t have one, look for clear juices when you insert a knife; if they run clear, it’s good to go!
How should I store leftovers from the Korean Gochujang roast chicken?
Absolutely! Let the cooked chicken cool down for no more than 2 hours at room temperature and then transfer it to an airtight container. You can store leftovers in the refrigerator for up to 3 days. To keep the flavors intact, I suggest storing any extra marinade separately.
Can I freeze the Korean Gochujang roast chicken?
Yes, freezing is a great option! To do this, portion the chicken into airtight freezer bags, removing as much air as possible, and freeze for up to 3 months. When you’re ready to enjoy it again, thaw the chicken in the refrigerator overnight for the best results.
What can I do if the chicken skin isn’t crispy enough?
If your chicken skin isn’t as crispy as you’d like after baking, you can always pop it under the broiler for 1-2 minutes. Just be sure to keep a close eye on it, as it can burn quickly! Another tip is to bake it uncovered for the last 15 minutes of cooking for additional crispness.
Is this recipe suitable for those with soy allergies?
Great question! If you or your guests have soy allergies, you can substitute the soy sauce with coconut aminos or use a gluten-free soy sauce alternative. This way, you can still enjoy the bold flavors of the Korean Gochujang roast chicken without any worries.
