Gochujang Flat Chicken with Crisp Skin

Gochujang flat chicken is a spatchcocked whole chicken roasted with a sticky, sweet-hot glaze made from Korean fermented chile paste. Flattening the bird helps it cook evenly, while adding the glaze near the end gives it time to caramelize without scorching.

Ingredients

1 whole chicken, 3½–4 lb (1.6–1.8 kg), giblets removed
1½ tsp fine salt (9 g)
½ tsp freshly ground black pepper (1 g)
1 tbsp neutral oil, such as canola (15 ml)
¼ cup gochujang (about 70 g)
2 tbsp honey (42 g)
1 tbsp soy sauce (15 ml)
1 tbsp unseasoned rice vinegar (15 ml)
1 tbsp toasted sesame oil (15 ml)
3 garlic cloves, finely grated or minced (about 9 g)
2 tsp finely grated fresh ginger (10 g)
2 scallions, thinly sliced, for serving (about 20 g)
1 tsp toasted sesame seeds, for serving (3 g)

Instructions

Heat the oven and prepare the pan. Set a rack in the center of the oven and heat it to 425°F (220°C). Line a rimmed baking sheet with foil for easier cleanup, then set a wire rack on top if you have one. The rack lets hot air circulate beneath the chicken and helps the underside roast rather than steam; the recipe still works directly on the lined sheet.
Flatten the chicken. Pat the chicken very dry with paper towels. Place it breast-side down on a sturdy cutting board. With poultry shears, cut along both sides of the backbone from tail to neck and remove it; save it for stock or discard it. Turn the chicken breast-side up and press firmly on the center of the breast until the breastbone gives and the bird lies relatively flat. Tuck the wing tips behind the breasts so they are less likely to burn.
Season and arrange. Mix the salt and pepper, then season both sides of the chicken, concentrating a little extra salt on the skin. Rub the skin with the neutral oil. Set the chicken breast-side up on the rack or baking sheet, with the legs angled outward. Wash your hands, board, and shears with hot soapy water after handling raw poultry.
Mix the glaze. In a small bowl, stir together the gochujang, honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger until smooth. Gochujang varies in heat and saltiness, so taste a small dab and adjust the honey or vinegar if you prefer a sweeter or brighter glaze. Keep the bowl and brush away from raw chicken; the glaze will be used later, after the chicken has started roasting.
Roast before glazing. Roast the chicken uncovered for 35 minutes. The skin should begin to brown and the legs may be nearing doneness, but the breast will likely need more time. Starting without the glaze gives the skin a chance to render and keeps the sugars in the honey from darkening too quickly.
Glaze and finish roasting. Remove the pan from the oven and brush a generous layer of glaze over the top of the chicken. Return it to the oven for 10–15 minutes, checking after 10 minutes. If the glaze is getting very dark before the chicken is done, loosely tent the top with foil and continue roasting. Check the thickest part of the breast and the innermost part of the thigh with a food thermometer, avoiding bone. The USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C); make sure both areas reach it before serving. If needed, roast in 3–5-minute increments and check again.
Rest and serve. Transfer the chicken to a clean cutting board and rest it for 10 minutes so the juices settle. Cut through the joints to separate the legs and wings, then slice the breast meat across the grain. Spoon any glaze left in the pan over the pieces, if it has not been in contact with raw chicken, and finish with scallions and sesame seeds.

Tips

Dry skin browns better. Blot the chicken thoroughly before seasoning. If you have time, you can leave it uncovered on a tray in the refrigerator for several hours, but that extra drying time is not included in the recipe timing. Keep raw chicken on the lowest shelf and away from ready-to-eat foods.
Use a thermometer, not color alone. Chicken size, starting temperature, and oven behavior all affect roasting time. Check breast and thigh separately, and keep roasting if either spot is below 165°F (74°C). A little pink near a joint does not tell you reliably whether the meat is safely cooked.
Adjust the heat carefully. Gochujang brands differ in spiciness. For a milder result, start with 3 tbsp (about 52 g) gochujang and add more to taste; for extra heat, add up to 1 tsp (5 ml) of a hot chile sauce. Do not reduce the glaze so much that it becomes mostly honey, which can burn faster.
Choose practical substitutes. If unseasoned rice vinegar is unavailable, use apple cider vinegar in the same amount; it tastes a little fruitier. Gochujang is the defining ingredient, but a pinch of miso mixed with sambal oelek and a little extra honey can approximate its savory, spicy character. That swap will be less fermented and will not taste exactly the same.

Serving Suggestions

Serve the chicken hot with steamed short-grain rice, which catches the savory-sweet glaze, and a crisp vegetable side such as cucumber salad, quick-pickled radish, or simply dressed greens. Roasted broccoli, green beans, or cabbage also make a satisfying plate; add them to a separate pan if the chicken pan is crowded, since vegetables can release moisture and soften the skin.

For a shared meal, carve the bird at the table and offer extra scallions, sesame seeds, and a small dish of gochujang for anyone who wants more heat. A squeeze of lime is optional and brings a sharper citrus note, while plain rice or flatbread helps balance a particularly spicy batch.

Variations

Use chicken pieces. Bone-in, skin-on thighs or drumsticks can take the same glaze. Arrange them with space between pieces, roast until nearly cooked, then brush with glaze and finish until every piece reaches 165°F (74°C). Pieces vary in size, so use a thermometer rather than relying on the whole-bird timing.
Make it less sweet. Reduce the honey to 1 tbsp (21 g) and add another teaspoon of rice vinegar. The glaze will be more tangy and less glossy, but still coats the chicken well. Brush it on near the end as directed.
Add a citrus-sesame finish. Stir 1 tsp (5 ml) lime juice into the glaze after cooking, or serve lime wedges at the table. Avoid adding much more liquid to the glaze before roasting, because a thinner coating is more likely to run off the skin.

Storage and Reheating

Refrigerate leftover chicken within 2 hours of cooking, ideally in shallow airtight containers. Carved pieces cool more quickly than a whole bird. Store them in the refrigerator for 3–4 days. If you have extra glaze that never touched raw chicken, refrigerate it separately and use it within 3–4 days; discard any glaze that contacted raw poultry unless it was thoroughly cooked.

For longer storage, freeze cooked chicken in a well-sealed container for up to 3 months for best quality. Thaw it in the refrigerator, not on the counter. Reheat portions covered in a 325°F (165°C) oven with a spoonful of water or broth to limit drying, or microwave them covered in short intervals. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. The skin will soften during storage and reheating; uncover for the final few minutes in the oven if you want to crisp it again.

Frequently Asked Questions

What does “flat chicken” mean?
It means the backbone has been removed and the chicken has been pressed open so it lies flatter on the pan. You may also see this method called spatchcocking or butterflying. It exposes more skin to the oven and helps the legs and breast cook more evenly than they often do when the bird is left whole.

Can I make the glaze ahead?
Yes. Stir it together up to 3 days ahead and keep it covered in the refrigerator. Bring it close to room temperature before brushing so it spreads easily. Use a clean spoon and brush, and do not dip either into sauce that has touched raw chicken unless that sauce is subsequently cooked thoroughly.

Can I marinate the chicken in the gochujang mixture?
You can, but it is not necessary for this recipe. A long coating of a sugary, salty paste can make the skin damp and may cause the glaze to darken before the center cooks. For the crispest skin and a bright glaze, season the chicken first and brush on the sauce during the last part of roasting.

Do I need a wire rack?
No. A rimmed baking sheet lined with foil is enough. A rack improves airflow and lets rendered fat drip away, so the underside is less likely to soften, but a chicken roasted directly on the pan will still cook safely. Turn the legs outward and leave room around the bird for heat to circulate.

How do I know where to check the temperature?
Insert the thermometer into the thickest part of the breast and the innermost part of the thigh, taking care not to touch bone. Check more than one spot because a spatchcocked chicken can cook unevenly. Both locations should reach 165°F (74°C) before you take the chicken out to rest.

Can I prepare this without cutting out the backbone?
Yes, roast a whole chicken using the same seasoning and glaze, but expect it to take longer and cook less evenly. Begin checking its temperature after about 60 minutes, then continue as needed until the breast and thigh each reach 165°F (74°C). The cooking time will depend on the bird’s size and shape, so the flat-chicken timing will not apply.
