Blackstone Korean BBQ Chicken Recipe (Easy & Delicious)

If you’ve been sleeping on Korean BBQ chicken, this is your wake-up call. I’m talking about sweet, savory, slightly spicy chicken with crispy edges that come out absolutely perfect on a Blackstone griddle. Korean BBQ chicken is one of those dishes a lot of people assume needs a grill or special equipment — but a flat top handles it beautifully, and it might be one of the most rewarding things you can make on one. The high, even heat of the flat top does something magical to the marinade – you get this caramelization that’s hard to achieve any other way. Plus, you can cook a ton of chicken at once, which means you’re not standing over a regular grill flipping individual pieces for an hour.

This recipe uses a marinade that hits all the right notes without requiring a trip to three different specialty stores. Authenticity matters, but so does actually getting dinner on the table on a Tuesday night. What you’ll end up with is tender chicken thighs with those crispy, slightly charred edges that make Korean BBQ so addictive. Let’s get into it.

Why Korean BBQ Chicken Works So Well on a Blackstone

The Blackstone’s flat surface gives you way more control than a traditional grill for this style of cooking. With Korean BBQ, you want high heat to caramelize all that sugar in the marinade, but you don’t want flare-ups from dripping fat burning your chicken to a crisp. On a regular grill, those sugars can cause serious charring problems. On the Blackstone, you get the sear and caramelization without the chaos.

The other huge advantage is space. Korean BBQ is meant to be a spread – chicken, vegetables, rice, the whole deal. With 36 inches of cooking surface, you can have your chicken going on one side and peppers, onions, or whatever else you want on the other side. Everything comes off hot at the same time. It’s the difference between a meal and an experience.

Ingredients You’ll Need

For the Chicken

• 3 pounds boneless, skinless chicken thighs (not breasts – trust me on this)
• 2 tablespoons vegetable oil for the griddle
• Sesame seeds for garnish
• Sliced green onions for garnish

For the Marinade

• 1/2 cup soy sauce (regular or low sodium, your call)
• 1/4 cup brown sugar, packed
• 3 tablespoons honey
• 3 tablespoons sesame oil
• 4 cloves garlic, minced (or about 2 teaspoons from a jar if that’s what you’ve got)
• 1 tablespoon fresh ginger, grated (or 1 teaspoon ground ginger)
• 2 tablespoons gochugaru (Korean red pepper flakes) – see note below
• 1 tablespoon rice vinegar
• 1/4 teaspoon black pepper
• 2 tablespoons water

A Note on Gochugaru

Gochugaru is Korean red pepper flakes, and it has a different flavor than regular crushed red pepper – slightly sweet, smoky, and not as intensely hot. You can find it at most Asian markets or order it online. If you absolutely can’t find it, you can substitute regular red pepper flakes, but use less – start with 1 teaspoon and adjust to your heat preference. The flavor won’t be quite the same, but you’ll still end up with great chicken. If you want to keep things simple and flavorful, Bachan’s Japanese Barbecue Sauce also works as a marinade base in a pinch, though it’ll give you a slightly different profile.

Step-by-Step Instructions

Step 1: Make the Marinade and Prep the Chicken

In a medium bowl, whisk together the soy sauce, brown sugar, honey, sesame oil, garlic, ginger, gochugaru, rice vinegar, black pepper, and water. Make sure that brown sugar breaks down completely – you don’t want clumps.

Trim any excess fat or weird bits from your chicken thighs, then cut them into roughly 2-inch pieces. You want them bite-sized but substantial enough that they won’t dry out. Chicken thighs are more forgiving than breasts because of the fat content, which is exactly why we’re using them.

Put the chicken pieces in a large zip-top bag or a bowl with a lid, pour the marinade over them, and make sure everything is coated. Seal it up and put it in the fridge. Minimum marinating time is 2 hours, but overnight is better if you can plan ahead. It’s easy to throw together in the morning and cook that evening.

Step 2: Prep Your Blackstone

About 30 minutes before you want to cook, pull the chicken out of the fridge. You want it to come closer to room temperature so it cooks more evenly. Don’t leave it out longer than that – we’re not trying to get food poisoning here.

Fire up your Blackstone and set all burners to medium-high. You’re aiming for a surface temperature around 400-425°F. If you’ve got a dual probe infrared thermometer, use it. If not, the water bead test works fine – flick some water on the griddle, and if it dances around in tight little beads before evaporating, you’re in the right range.

Once you hit temp, add about 2 tablespoons of vegetable oil to your cooking zone and spread it around with a spatula or paper towel held with tongs. You want a thin layer covering the area where your chicken will go.

Step 3: Cook the Chicken

Pull the chicken pieces out of the marinade, but don’t shake off all that marinade – you want some of it clinging to the chicken because that’s where the flavor and caramelization come from. Reserve the leftover marinade in the bag or bowl – we’ll come back to that.

Lay the chicken pieces on the griddle, giving them a little space between each piece. You don’t want them crowded or they’ll steam instead of sear. Depending on the size of your griddle and how much chicken you’re making, you might need to work in batches. Don’t rush this part.

Let the chicken cook without moving it for about 4-5 minutes. You’re looking for a dark, caramelized crust to develop on the bottom. This is where the magic happens. The sugars in the marinade are caramelizing, the edges are crisping up, and your whole backyard starts smelling incredible. The aroma at this point is incredible.

Flip each piece and cook for another 4-5 minutes on the second side. The chicken should be getting nicely browned with some darker, almost charred spots here and there. That’s exactly what you want.

Step 4: Add More Marinade

Here’s where things get even better. Take that reserved marinade and pour some of it over the chicken pieces as they finish cooking. It’ll hit the hot griddle and immediately start bubbling and reducing into a glaze. Use your spatula to move the chicken around a bit, coating the pieces in that glaze as it thickens.

Cook for another 2-3 minutes, stirring and flipping occasionally, until the chicken is cooked through (internal temp should hit 165°F) and coated in a sticky, caramelized glaze. If the marinade starts to burn or things are getting too dark, dial back your heat to medium.

Step 5: Rest and Serve

Pull the chicken off the griddle onto a serving plate. Let it rest for a couple minutes – this isn’t as critical as with a big steak, but it helps the juices redistribute.

Sprinkle with sesame seeds and sliced green onions. Serve it however you want – over rice, in lettuce wraps, with kimchi and other banchan on the side, or just straight up with some steamed vegetables.

Pro Tips for Perfect Korean BBQ Chicken

Use chicken thighs, not breasts. I know some people prefer white meat, but thighs have more fat and more flavor. They’re also way more forgiving on high heat. Breasts will work if that’s all you have, but you’ll need to watch them more carefully to avoid drying them out.

Don’t skip the marinating time. Two hours is the minimum. The marinade needs time to penetrate the meat and break down the proteins a bit. Overnight is ideal if you can plan for it.

Control your heat zones. If you’ve got a multi-burner Blackstone, you can set up different heat zones. Keep one area at that 400-425°F for the initial sear, and have a medium zone (around 350°F) ready in case you need to move pieces that are browning too fast.

Watch for burning. The sugar in the marinade is your friend for caramelization but your enemy if things get too hot. If you see the glaze turning black instead of deep brown, your temp is too high. Drop it down and keep the chicken moving.

Work in batches if you need to. It’s tempting to throw all the chicken on at once, but if the pieces are touching, you won’t get that crispy exterior. Better to do two batches and have everything turn out great.

Save some uncooked marinade. If you want extra sauce to serve on the side, set some marinade aside before it touches the raw chicken. You can simmer it in a small pot on your stove or even on the griddle in a small pan to thicken it up into a dipping sauce. Keep extra marinade in restaurant squeeze bottles for easy drizzling at the table.

Common Mistakes to Avoid

Using chicken straight from the fridge. Cold chicken hitting a hot griddle cooks unevenly. The outside overcooks before the inside comes up to temp. Let it sit out for 20-30 minutes first.

Not preheating the griddle enough. If your griddle isn’t hot enough, the chicken will stick and you won’t get that caramelized crust. Get it properly preheated to 400-425°F before the chicken goes on.

Flipping too early. When you first put the chicken down, it’s going to want to stick a bit. That’s normal. Give it time to develop a crust, and it’ll release naturally. If you try to flip it too soon, you’ll tear the chicken and lose all that good crust.

Crowding the cooking surface. Space is your friend. Crowded chicken steams. Spaced-out chicken sears. Simple as that.

Throwing away the marinade. A lot of recipes tell you to toss marinade that’s touched raw meat, and that’s generally good advice for food safety. But if you’re cooking it on a 400°F griddle and letting it bubble and reduce, you’re killing any bacteria. That said, if this makes you nervous, just set aside some fresh marinade before adding the chicken.

What to Serve with Korean BBQ Chicken

This chicken is versatile. The classic move is to serve it over white rice with some kimchi and other Korean side dishes. You can also go the lettuce wrap route – get some butter lettuce or red leaf lettuce, add some rice, a piece of chicken, maybe some gochujang mayo, and wrap it up.

If you want to keep everything on the Blackstone, throw some sliced bell peppers and onions on the other side of the griddle while your chicken cooks. The vegetables pick up some of that chicken flavor from the griddle and make a great side. You can also do some halved baby bok choy – just hit them with some oil and let them char a bit.

Rice is the obvious carb, but this chicken also works great over fried rice if you want to go all-in on the griddle. Make the chicken first, set it aside, then use that same flavorful griddle surface to make fried rice. Everything tastes better with a little chicken drippings in the mix.

Frequently Asked Questions

Can I use chicken breasts instead of thighs?

You can, but thighs are really the better choice here. Breasts are leaner and easier to overcook, especially at the high heat needed to caramelize the marinade. If you’re committed to breasts, pound them to an even thickness and watch your cooking time carefully. Pull them at 160°F and let carryover cooking bring them to 165°F.

How spicy is this recipe?

With the full 2 tablespoons of gochugaru, it’s got a medium kick – you’ll feel some heat but it’s not overwhelming. Gochugaru is milder than most people expect. If you’re sensitive to spice, start with 1 tablespoon. If you like it hot, you can go up to 3 tablespoons or add some gochujang (Korean red pepper paste) to the marinade.

Can I make this ahead?

The chicken can marinate for up to 24 hours in the fridge, which actually makes it even better. As for cooked chicken, it’ll keep in the fridge for 3-4 days. Reheat it on the Blackstone or in a skillet – the microwave will make it soggy. It also freezes well for up to 3 months.

What if I don’t have sesame oil?

Sesame oil adds a distinctive nutty flavor that’s pretty important to Korean cooking, but if you don’t have it, you can use vegetable oil or olive oil in the marinade. The flavor profile will change a bit, but the chicken will still be good. Pick up some sesame oil for next time though – a bottle lasts forever and it’s worth having around.

Can I cook this on a regular griddle or in a pan?

Sure. The technique is the same – you just won’t have as much cooking space. A cast iron pan or stovetop griddle works fine. You’ll probably need to work in smaller batches, and make sure your ventilation is good because that marinade will create some smoke when it hits the hot surface.

Should I cut the chicken before or after cooking?

Before. Cutting it into pieces before marinating lets the marinade penetrate better, and smaller pieces cook faster and more evenly on the griddle. You also get more of those delicious crispy edges when you’ve got more surface area exposed.

Final Thoughts

This Korean BBQ chicken makes a great addition to any Blackstone rotation. It comes together quickly once the chicken’s marinated, and it’s the kind of meal that feels special even though it’s not complicated. The sweet-savory-spicy thing just works, and those caramelized edges you get from the flat top griddle make all the difference.

The best part is how adaptable this is. Make it as written, or adjust the heat level, throw some vegetables on the griddle alongside the chicken, serve it different ways throughout the week. The marinade is the star, and as long as you’ve got that going for you and a properly heated griddle, you’re pretty much guaranteed a win.

If you’ve been thinking about branching out from burgers and smash patties on your Blackstone, this is a great recipe to try. It’s different enough to feel like something new, but straightforward enough that you’re not going to stress about it. Give it a shot and let me know how it goes.
