Gochujang Chicken and Roasted Vegetables

Gochujang chicken and roasted vegetables pairs tender chicken with broccoli, carrots, bell pepper, and onion coated in a sweet-savory Korean chile paste glaze. It is a weeknight-friendly, Korean-inspired sheet-pan dinner: the vegetables roast until browned at the edges while the chicken cooks through, and rice makes an easy base for the flavorful pan juices.

Ingredients

1½ lb boneless, skinless chicken thighs, cut into 1-inch (2.5 cm) pieces (680 g)
2 tbsp gochujang (30 g), a Korean fermented chile paste
1½ tbsp soy sauce (22 ml)
1 tbsp honey (21 g)
1 tbsp unseasoned rice vinegar (15 ml)
2 tsp toasted sesame oil (10 ml)
3 garlic cloves, finely grated or minced (about 1 tbsp / 9 g)
2 tsp finely grated fresh ginger (about 4 g)
1 large broccoli crown, cut into bite-size florets (about 12 oz / 340 g)
1 large red bell pepper, cut into 1-inch (2.5 cm) pieces (about 7 oz / 200 g)
2 medium carrots, cut on the diagonal into ¼-inch (6 mm) slices (about 6 oz / 170 g)
1 medium red onion, cut into 1-inch (2.5 cm) wedges (about 6 oz / 170 g)
1 tbsp neutral oil, such as canola or avocado oil (15 ml)
½ tsp kosher salt (about 3 g), plus more to taste
¼ tsp freshly ground black pepper (about 0.5 g)
1 tsp sesame seeds for garnish (3 g), optional
2 scallions, thinly sliced (about 15 g), optional

Instructions

Heat the oven to 425°F (220°C). Line two large rimmed sheet pans with parchment for easier cleanup, if desired. Using two pans gives the vegetables room to brown instead of steam and keeps the raw chicken separate from them during preparation.
In a medium bowl, whisk together the gochujang, soy sauce, honey, rice vinegar, sesame oil, garlic, and ginger. Transfer about 2 tablespoons of the mixture to a small clean bowl and set it aside for finishing. Add the chicken to the remaining sauce and toss until coated. Wash your hands and any utensil that touched raw chicken before handling other ingredients.
Put the broccoli, bell pepper, carrots, and red onion in a large bowl. Add the neutral oil, salt, and black pepper, then toss to coat. Spread the vegetables across one sheet pan in a single layer, leaving a little space between pieces. Spread the chicken on the second pan, separating the pieces so hot air can circulate. Discard any sauce left in the bowl that held the raw chicken.
Roast both pans for 12 minutes, placing them on separate oven racks. Swap the pans between the upper and lower racks and rotate each pan from front to back. Stir the vegetables and turn the chicken pieces with a clean spatula. Roast for another 8–13 minutes, until the vegetables are browned and tender and the thickest chicken pieces reach 165°F (74°C) on a food thermometer. The USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C); check a few pieces in their centers rather than judging doneness by color alone.
Remove the pans from the oven. Spoon or brush the reserved, untouched gochujang mixture over the cooked chicken and toss to coat. Taste a vegetable and add a little salt if needed. Scatter the sesame seeds and scallions over the pans, if using, and serve while hot.

Tips

Choose your gochujang thoughtfully. Gochujang varies by brand in heat, saltiness, and sweetness, so the glaze is intentionally balanced with honey, vinegar, and soy. If yours is especially hot, start with 1½ tablespoons (about 22 g) and add more to taste. If it is mild, use the full amount. Do not replace it with plain chile flakes; gochujang has a fermented, savory depth as well as heat.
Adjust for what is in the refrigerator. Cauliflower florets, sliced zucchini, or green beans can take the place of some of the vegetables. Cut firm vegetables small enough to cook in about 20–25 minutes, and keep the total quantity similar so the pan does not become crowded. If using zucchini, cut it into thicker pieces because it softens faster and releases more moisture.
Keep the glaze from scorching. Honey and the sugars in gochujang can darken quickly. Use the stated oven temperature, cut the chicken into even pieces, and start checking the chicken at 20 minutes. If the glaze on a piece looks very dark before the center is cooked, loosely cover that pan with foil for the remaining roasting time.
Use separate utensils for raw and cooked chicken. Keep the reserved finishing sauce in a clean bowl before tossing raw chicken in the rest. Never brush that reserved sauce onto the cooked food with a utensil that touched raw poultry.

Serving Suggestions

Serve the chicken and vegetables over warm steamed short-grain rice, brown rice, or another grain that can catch the glossy sauce. For four portions, about 3 cups (570 g) cooked rice is a useful amount. If you prefer noodles, toss cooked wheat or rice noodles with a spoonful of water and a little sesame oil, then serve the chicken and vegetables on top. A bowl of rice also makes it easy to balance the chile paste’s savory heat with the more neutral grains.

For a fresh contrast, add thinly sliced cucumber dressed with rice vinegar and a pinch of salt, or serve kimchi on the side. A squeeze of lime is not traditional to every Korean-style meal, but it can brighten this particular glaze if you enjoy a sharper finish. Keep extra garnishes simple: scallions, sesame seeds, or a few torn cilantro leaves are enough. Because the dish already includes a savory, salty sauce, taste before adding more soy sauce at the table.

Variations

Make it milder: Reduce the gochujang to 1 tablespoon (15 g) and add 1 tablespoon (15 ml) water or a little extra honey to keep the sauce easy to toss. The result will be less chile-forward and somewhat sweeter. For more heat, add gochugaru, Korean red pepper flakes, a pinch at a time; ordinary crushed red pepper is a sharper, less fruity substitute.

Use chicken breast: Boneless, skinless breast works, but it is leaner and can dry out if cut too small or roasted too long. Cut it into evenly sized 1-inch (2.5 cm) pieces, begin checking around 16 minutes, and remove it as soon as the thickest piece reaches 165°F (74°C). Keep the vegetables on their own pan and let them finish roasting if they need more time.

Try a different protein: Cubes of extra-firm tofu can replace chicken for a plant-based version. Press the tofu to remove excess water, cut it into 1-inch (2.5 cm) cubes, toss it with part of the sauce, and roast it on a separate pan until browned, usually about 25–30 minutes, turning once. Use the reserved clean sauce at the end. Tofu browns differently from chicken, so judge it by its texture and color rather than a meat temperature.

Swap the vegetables by season: Use cauliflower, mushrooms, or halved Brussels sprouts in place of some of the listed vegetables. Mushrooms release water, so leave generous space around them; Brussels sprouts may need to be halved or quartered to cook in the same window. For a less spicy, less fermented flavor, mild miso mixed with a little chile paste can stand in for some gochujang, but it will not taste exactly the same.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a shallow, airtight container. Keep the chicken and vegetables together or separate them from the rice so the rice does not absorb all the sauce. Properly refrigerated, the cooked chicken and vegetables keep for 3–4 days. If you made rice, refrigerate it promptly in its own container and use it within the same 3–4-day window.

For the best texture, reheat a portion in a skillet over medium heat with 1–2 teaspoons (5–10 ml) water, stirring occasionally until steaming hot. A microwave also works: cover loosely, heat in short intervals, and stir or turn the pieces so they warm evenly. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. The vegetables will be softer after storage, but reheating in a skillet can bring back a little browned texture. Freeze portions in airtight containers for up to 2 months for best quality; thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Is gochujang very spicy?

It can be, but its heat varies by product and is usually accompanied by sweetness, salt, and a deep fermented flavor. This recipe uses 2 tablespoons (30 g) for four servings, which makes a noticeable but balanced chile glaze. Start with less if your gochujang is unfamiliar, then add more to the sauce before it touches the chicken.

Can I make this on one sheet pan?

Possibly, if your pan is very large and the ingredients fit in a single layer with space between them. A standard half-sheet pan is often too crowded for this amount of chicken and vegetables; crowding traps steam and limits browning. Two pans are more dependable. If using one, reduce the quantities or roast in batches rather than piling the ingredients up.

Can I marinate the chicken ahead?

Yes. Coat the chicken in the main portion of sauce, cover, and refrigerate for up to 8 hours. Keep the clean finishing sauce separate and refrigerated. Count the marinating time as additional elapsed time, and do not leave raw chicken at room temperature while the oven heats or the vegetables are prepared.

What can I use instead of gochujang?

There is no exact substitute, because gochujang is a fermented Korean chile paste with its own savory sweetness. In a pinch, mix mild miso with a small amount of sambal oelek or another chile paste, then add a little honey to round it out. The flavor will be less distinctly Korean and may be saltier or sharper, so start with less soy sauce and taste the mixture before coating the chicken.

How do I know the chicken is done?

Check the center of the thickest chicken pieces with an instant-read food thermometer. Poultry should reach 165°F (74°C), the USDA FSIS safe minimum temperature. Color and clear-looking juices are not as reliable as a thermometer, especially when the pieces vary slightly in size.

Can I prepare the vegetables in advance?

Yes. Cut the vegetables up to a day ahead and refrigerate them in a covered container. Keep them dry and wait to add the oil and seasoning until just before roasting. This keeps the broccoli from becoming damp and makes it easier to spread everything in an even layer when you are ready to cook.
