Ingredients You’ll Need

Boneless Chicken Thighs

Chicken thighs are ideal for buldak because they remain tender and juicy while simmering in the spicy sauce. Cut them into bite-sized pieces for easier cooking and serving. Chicken breasts can also be used.

Gochugaru

Gochugaru is a Korean red pepper flake that provides characteristic Korean chili flavor and heat. It plays an important role in creating the fiery sauce.

Gochujang

Gochujang is a Korean fermented chili paste with a combination of spicy, savory, slightly sweet, and umami flavors. For an especially fiery buldak, use a hot variety.

Soy Sauce

Soy sauce adds saltiness and savory depth to the marinade.

Vegetable Oil

Vegetable oil helps bring the marinade together and coats the chicken.

Sesame Oil

Sesame oil adds a distinctive nutty aroma and flavor that complements the Korean seasonings.

Rice Syrup

Rice syrup adds sweetness to balance the heat and savory ingredients. Honey or corn syrup can also be used.

Korean Chili Peppers

Fresh spicy Korean chili peppers add another layer of heat and fresh chili flavor. Other small spicy red chilies can be substituted.

Garlic

Six large cloves of minced garlic give the sauce a strong, aromatic garlic flavor.

Ginger

Freshly grated ginger adds warmth and brightness to the spicy marinade.

Salt and Black Pepper

Season with salt and black pepper according to taste.

Water or Chicken Stock

A small amount of water or chicken stock helps the chicken cook gently while allowing the sauce to reduce.

Mozzarella Cheese

Shredded mozzarella is optional but highly recommended if you enjoy cheesy buldak. It melts beautifully over the hot chicken and provides a creamy contrast to the spicy sauce.

Garnishes

Fresh parsley or green onions and extra hot pepper flakes can be used to finish the dish.

How to Make Buldak Recipe

Prepare the Spicy Marinade

In a large bowl, combine the gochugaru, gochujang, soy sauce, vegetable oil, sesame oil, rice syrup, chopped Korean chilies, minced garlic, grated ginger, salt, and black pepper.

Mix everything together until you have a thick, flavorful paste.

The marinade should be rich and concentrated because it will become the sauce for the chicken as it cooks.

Marinate the Chicken

Add the chopped chicken thighs to the bowl and toss thoroughly until every piece is coated with the spicy marinade.

Cover the bowl and refrigerate for at least 1 hour.

If you have extra time, allowing the chicken to marinate longer can help the flavors penetrate the meat even further.

Cook the Chicken

Heat a large oven-proof skillet, preferably cast iron, over medium heat.

Add the chicken along with all of the marinade to the skillet. Pour in the water or chicken stock and stir gently to combine.

Cover the skillet and simmer for about 10 minutes, or until the chicken is cooked through.

As the chicken cooks, the sauce will reduce and become thicker and more concentrated.

Add the Cheese

Once the chicken is cooked, remove the lid.

Set your oven to broil.

Sprinkle the shredded mozzarella evenly over the chicken.

Place the skillet under the broiler and cook for approximately 2–3 minutes, or until the cheese is melted, bubbling, and beginning to brown.

Keep a close eye on the skillet while broiling because the cheese can brown quickly.

Garnish and Serve

Carefully remove the hot skillet from the oven.

Garnish the buldak with chopped fresh parsley or green onions and, if desired, an extra sprinkle of hot pepper flakes.

Serve immediately while the cheese is hot and melted.

Tips for Success

Adjust the Heat Gradually

Buldak is supposed to be spicy, but you can control the intensity. Start by reducing the amount of fresh chilies or choosing a milder gochujang if you’re sensitive to heat.

Don’t Skip the Marinade

The marinade is what gives this dish its distinctive flavor. Allowing the chicken to sit for at least one hour gives the seasonings time to work into the meat.

Cut the Chicken Evenly

Cut the chicken into similar-sized bite-sized pieces so everything cooks at roughly the same rate.

Use an Oven-Safe Skillet

Because the chicken is finished under the broiler, use a skillet that’s safe for both stovetop and high-heat oven use. Cast iron is an excellent choice.

Watch the Broiler

The mozzarella only needs about 2–3 minutes under the broiler. Stay nearby and watch carefully so the cheese melts and browns without burning.

Let the Sauce Reduce

The chicken initially cooks with a little water or stock, allowing it to simmer gently. Removing the lid afterward lets excess moisture evaporate and concentrates the sauce around the chicken.

Equipment Needed

• Large mixing bowl
• Measuring spoons and cups
• Large oven-safe skillet or cast iron pan
• Cutting board
• Sharp knife
• Grater for fresh ginger
• Tongs or spatula
• Oven broiler

Recipe Variations

Make It Less Spicy

Reduce the fresh Korean chilies and use a milder gochujang. You can also decrease the amount of gochugaru while keeping the other ingredients unchanged.

Make It Extra Spicy

For serious heat lovers, add extra Korean chili peppers and a little more gochugaru. You can also finish the dish with additional hot pepper flakes.

Use Chicken Breast

Chicken breasts work well if you prefer leaner meat. Cut them into even bite-sized pieces and avoid overcooking them so they remain tender.

Try a Different Cheese

Mozzarella is a classic choice for cheesy buldak because of its excellent melting qualities, but you can experiment with other mild melting cheeses.

Make It Without Cheese

The cheese is optional. Simply cook the chicken until the sauce has reduced and serve it with your favorite Korean-inspired sides.

What to Serve With Buldak

Because buldak is intensely flavored and spicy, it pairs especially well with simple sides that balance the heat.

Try serving it with:

• Steamed white rice
• Korean-style pickled vegetables
• Cucumber salad
• Steamed vegetables
• Green onions
• Kimchi
• Fresh lettuce leaves

A bowl of plain rice is particularly useful for soaking up the spicy sauce and mellowing the heat between bites.
