Use a sharp knife to trim any large portions of fat, and then pat dry the chicken thighs with paper towels.
Measure and add all the marinade ingredients to a small bowl. Mix until everything is combined.
Place the chicken thighs in a Ziploc bag (or a large bowl), then add the marinade. Close the bag and give the chicken a good shake (or stir if you're using a bowl) so all the thighs are evenly covered with marinade. Let it sit in the fridge for at least 2 hours and up to overnight.
Grilling
Prepare your grill for two zone cooking.
Charcoal Grill: Push the hot coals to one side of the grill for a hot zone and leave the other side empty for a cool zone.
Gas Grill: Turn one side to medium-high heat and leave the other side off or on low.
Oil the grates before grilling.
Place the chicken skin-side up on the indirect heat zone, insert your thermometer probe and close the lid. Let it cook until the internal temperature of the chicken is 165°F (approximately 15-20 minutes).
Move the cooked chicken to the hot side for 1–2 minutes per side for some charring.
Let the chicken rest for 5 minutes. Optionally, sprinkle sesame seeds and sliced green onions over it. Enjoy!
Notes
✔️Gochujang (Korean chili paste) – This chili paste is fermented, so the flavor is spicy but more complex. Give it a taste if you’ve never tried it before. You can use less or mix it with ketchup or tomato paste. If you don’t like or can’t find gochujang, try Sriracha.✔️The spicy gochujang marinade also makes an excellent dipping sauce! We double the recipe and keep half to use after grilling.✔️If you're in a rush, you can get away with just 30 minutes of marinating. Allowing 2 hours will give the thighs a more intense flavor, but overnight is ideal for the best flavor infusion.
