Spicy chicken bulgogi, or dak bulgogi (닭불고기), is one of those Korean BBQ dishes that rewards you almost immediately. The chicken soaks up a savory-sweet marinade with gochujang, garlic, ginger, soy sauce, and sesame oil, then hits high heat until the edges become dark, sticky, and slightly smoky.
I like using boneless chicken thighs here because they stay juicy while the marinade caramelizes. Broiling is especially handy at home: the chicken cooks quickly, the sauce gets those little charred spots, and you don't need to fire up a grill.
Serve it with hot rice, kimchi, sliced scallions, and perilla leaves if you have them. The cool, fresh crunch alongside the spicy chicken is exactly what makes each bite work.

Instructions
Trim any large pieces of excess fat from the chicken. If the thighs are unevenly thick, place them between sheets of plastic wrap and gently pound them until they are an even thickness. This helps the thinner edges and thicker centers finish cooking at the same time.
Whisk the gochujang, gochugaru, soy sauce, brown sugar, corn syrup, garlic, ginger, mirin, sesame oil, and black pepper in a large bowl until smooth. The marinade should be thick enough to cling to the chicken rather than run off.
Add the chicken and turn each piece several times until completely coated. Cover and refrigerate for about 2 hours. If you're short on time, 30 minutes will still season the surface, but the longer rest gives the chicken noticeably deeper flavor.
Take the chicken out of the refrigerator while you heat the broiler. Position an oven rack about 5 to 6 inches from the broiler and heat the broiler on high. Line a baking sheet with foil and set a lightly oiled wire rack on top.
Lift the chicken from the marinade, letting the excess drip back into the bowl, and arrange the thighs in one layer on the rack. Don't crowd them. Too much chicken packed together traps moisture and gives you steamed chicken instead of those caramelized edges.
Broil for 4 to 5 minutes, watching closely as the gochujang and sugar begin to blister and darken. Flip the chicken and broil for another 4 to 5 minutes, or until the thickest part reaches 165°F (74°C). If the edges are browning very quickly, move the tray slightly farther from the heat.
Transfer the chicken to a cutting board and let it rest for 3 to 5 minutes. Slice into bite-sized pieces. The juices should stay inside rather than running across the board.
Sprinkle with sesame seeds, green onions, and sliced perilla if using. Serve hot with steamed rice, kimchi, lettuce leaves, and ssamjang.
Notes & Variations
For a milder version, leave out the gochugaru and use a little less gochujang. The chicken will still have plenty of savory Korean BBQ flavor.
Watch the broiler closely near the end. Gochujang and sugar caramelize beautifully, but they can go from dark and glossy to burnt surprisingly fast.
Boneless chicken thighs are the safest choice for juicy results. Chicken breast works, but slice it evenly and pull it from the heat as soon as it reaches 165°F (74°C).
Store cooked chicken in an airtight container in the refrigerator for up to 4 days. Reheat gently in a skillet or microwave until hot; a splash of water helps keep the chicken from drying out.

FAQ
Q: Can I make spicy chicken bulgogi less spicy?
Yes, leave out the gochugaru and reduce the gochujang slightly for a gentler version. Gochujang still gives the chicken its deep red color and savory fermented flavor, so you don't need to remove it completely. If you're serving children or anyone sensitive to heat, start with 2 tablespoons and add more next time.
Q: Why does my chicken bulgogi burn before the chicken is cooked?
The marinade contains sugar and gochujang, so it can darken quickly under a hot broiler. Keep the chicken about 5 to 6 inches from the heat, watch it closely after the first few minutes, and move the tray lower if the surface is burning before the center reaches 165°F (74°C).
Q: Can I use chicken breast instead of thighs for chicken bulgogi?
Yes, chicken breast works, but boneless thighs are more forgiving and stay juicier under high heat. If using breast, cut the pieces evenly so they cook at the same rate and avoid leaving them under the broiler once they reach 165°F (74°C).
Q: How long can I store cooked chicken bulgogi?
Cooked chicken bulgogi keeps well in an airtight container in the refrigerator for up to 4 days. Reheat only the amount you plan to eat, using a skillet over medium-low heat or short microwave intervals so the chicken doesn't become tough.
Q: How long should I marinate chicken bulgogi?
About 2 hours gives the chicken a good balance of flavor and texture. A shorter 30-minute marinade will work when dinner is rushed, while several hours lets the garlic, ginger, soy, and gochujang season the chicken more deeply; avoid excessively long marinating because the texture can change.
