Ingredients You’ll Need

The magic of this Sweet and Spicy Korean Fried Chicken (Yangnyeom Chicken) Recipe lies not only in technique but also the harmony of its ingredients. Each element combines to deliver that iconic Korean fried chicken experience, from the tender chicken thighs to the vibrant sauce.

  • Chicken Thigh Fillet: I prefer boneless, skinless thighs because they’re naturally juicy and tender, making the chicken super flavorful.
  • Potato Starch: This is your secret weapon for a light, crispy coating—much better than regular flour in this recipe.
  • Gochujang: This Korean chili paste provides the signature spicy, slightly sweet kick—the backbone of the sauce.
  • Garlic: Adds depth and a savory touch to both the chicken brine and sauce.
  • Ketchup: Balances the heat with sweetness and acidity in the sauce.
  • Soy Sauce: Brings saltiness and umami flavor, rounding out the sauce beautifully.
  • Corn Syrup: Gives the sauce that glossy finish and helps it cling irresistibly to the chicken.
  • Egg: Helps the starch batter stick perfectly to the chicken.
  • Vegetable or Canola Oil: Go for a neutral oil that’s great for frying at high temperatures without burning.
  • Salt and Pepper: Essential for seasoning the chicken well before frying.
  • Sugar: Adds a mellow sweetness to balance the spicy, tangy sauce.
  • Water: Used to loosen up the potato starch so your batter isn’t too thick or thin.

Variations

I love how versatile this Sweet and Spicy Korean Fried Chicken (Yangnyeom Chicken) Recipe is—you can easily tweak it to suit your tastes or dietary needs. Feel free to make it your own and experiment with flavors!

  • Spicy Level: If you like it hotter, add a dash of Korean chili flakes (gochugaru) or extra gochujang to the sauce for more heat.
  • Gluten-Free: Just make sure your soy sauce is gluten-free and use potato starch for coating—this recipe is naturally adaptable.
  • Chicken Cuts: I’ve tried wings and drumsticks with this recipe, and it works just as well—adjust frying times accordingly.
  • Sweetener Swap: Instead of corn syrup, you can use honey or maple syrup, though it changes the texture slightly.

How to Make Sweet and Spicy Korean Fried Chicken (Yangnyeom Chicken) Recipe

Step 1: Prep and Brine Your Chicken

Start by chopping your chicken thighs into bite-sized pieces—this makes for perfect finger food. Toss them into a bowl with salt, pepper, minced garlic, and a beaten egg. This brine step is crucial because it seasons your chicken internally and helps tenderize the meat. Pop it in the fridge for at least an hour (I usually do an hour or two if I have time). You’ll notice the chicken becomes juicier and the flavor way more balanced after this.

Step 2: Coat the Chicken with Potato Starch Batter

Once your chicken’s nicely brined, add potato starch and gradually add water, mixing as you go. The batter should be thick enough to coat the chicken but still fluid enough to give a light, crispy finish—not too gloopy or runny. This is where I always pay close attention, because consistency here makes all the difference in the crunch factor.

Step 3: Double Fry for Crispy Perfection

Heat your oil to 350°F (about 175°C). Fry the coated chicken in batches—crowding the pan will drop your oil temperature and lead to soggy chicken. Cook for 5-6 minutes until the coating turns light golden. Drain and let rest a couple minutes. Then, this is the magic moment: smash the chicken gently to create tiny air pockets inside, which will make the crust even crispier during the second fry. Bring your oil temperature up to 375°F (190°C) and fry for another 2 minutes. This two-step frying technique is a game-changer and something I discovered makes all the difference!

Step 4: Make and Toss in the Sweet and Spicy Sauce

While the chicken cools on a wire rack, whisk together gochujang, ketchup, soy sauce, minced garlic, sugar, and corn syrup. Simmer it gently on low heat just for a couple minutes until it thickens slightly and flavors meld. Then, quickly toss your hot fried chicken into the sauce—this step coats them evenly and pulls everything together. Serve right away for that irresistible sticky, spicy, and sweet bite!

Pro Tips for Making Sweet and Spicy Korean Fried Chicken (Yangnyeom Chicken) Recipe

  • Consistent Oil Temperature: I always use a thermometer for frying—maintaining 350°F first, then 375°F later is the secret to crispy, non-greasy chicken.
  • Avoid Overcrowding: Fry the chicken in small batches to keep the oil hot and crispy every time.
  • Prep Ahead: Brining the chicken for an hour or more in advance really improves texture and flavor, so don’t rush this step.
  • Sauce Application: Toss the chicken in sauce while it’s hot but not piping hot to keep the coating crisp and not soggy.

Garnishes

I love topping my yangnyeom chicken with a sprinkle of toasted sesame seeds and some thinly sliced green onions or chives for a fresh pop of color and a hint of crunch. Sometimes, I throw on a few fresh chili slices if I want to dial up the visual heat and a spicy kick.

Side Dishes

Sweet and Spicy Korean Fried Chicken pairs beautifully with simple sides like steamed white rice, pickled radish (my absolute favorite), or a crisp cucumber salad to cut through the heat. For a more indulgent meal, try serving alongside kimchi or some fried rice for extra flavor.

Creative Ways to Present

For special occasions, I like serving this chicken on a big wooden platter sprinkled with chopped scallions and sesame seeds, alongside small bowls of dipping sauces like extra gochujang or ranch for the less adventurous eaters. It always makes the meal feel festive and extra inviting when everyone can dig in family-style.

Make Ahead and Storage

Storing Leftovers

I keep leftover yangnyeom chicken in an airtight container in the fridge for up to 2 days. While it loses a bit of its crispiness, reheating thoughtfully brings it back to life.

Freezing

You can freeze the fried but unsauced chicken pieces in a single layer on a baking sheet, then transfer to freezer bags once solid. Freeze for up to a month. This way, you can make the sauce fresh when reheating to keep everything tasting vibrant.

Reheating

To reheat without losing crunch, I recommend popping the chicken on a wire rack in a 350°F oven for 10-15 minutes. Once heated through, toss it fresh in warmed sauce. This way, you get maximum crispiness back and the sauce stays sticky and fresh-tasting.

FAQs

  1. Can I use chicken breast instead of chicken thighs for this recipe?

    You can, but chicken thighs are preferred because they stay juicier and more tender during frying. Chicken breast tends to dry out faster, so if you do use them, be extra careful not to overcook and consider brining slightly longer.

  2. What if I don’t have potato starch? Can I substitute with something else?

    Potato starch creates a lighter, crispier coating compared to other flours. You can substitute with cornstarch in a pinch, but the texture might be slightly different—still delicious, but less light.

  3. How spicy is this Sweet and Spicy Korean Fried Chicken?

    The spiciness depends on how much gochujang you use—it offers a moderate heat balanced with sweetness. You can always adjust the heat by adding more gochujang or chili flakes to your personal preference.

  4. Is the sauce too sticky? How do I prevent it from being gloopy?

    Simmering the sauce gently helps it thicken just enough. Avoid boiling harshly, which can make it overly thick and sticky. A glossy coat that’s easy to toss your chicken in is the goal.

  5. What’s the best way to keep the fried chicken crispy after saucing?

    Serve immediately after tossing in the sauce. The crispiness is best enjoyed fresh. If preparing in advance, keep chicken and sauce separate until serving.

Final Thoughts

This Sweet and Spicy Korean Fried Chicken (Yangnyeom Chicken) Recipe holds a special place in my heart because it always brings people together—whether it’s a casual weeknight meal or a party favorite. I remember the first time I nailed the double frying and sauce combo, and honestly, it felt like a little personal victory. I really hope you give this a try and make it yours. Trust me, you’ll love the way this crunchy, saucy goodness fills your kitchen and your belly. Happy cooking!

Description

Sweet and Spicy Korean Fried Chicken, also known as Yangnyeom Chicken, is crispy double-fried chicken thighs coated in a rich, flavorful sauce made with gochujang, garlic, and a sweet blend of ketchup and corn syrup. This dish balances savory, spicy, and sweet elements, creating an irresistibly crispy and tangy Korean classic perfect for gatherings or a delicious meal.


Ingredients

Chicken and Batter

  • 500 grams Chicken Thigh Fillet (skin and fat removed, cut into bite-size pieces)
  • 1/2 tsp Salt
  • Pepper, to taste
  • 1 tbsp Garlic (minced)
  • 1 pc Egg
  • 1 cup Potato Starch
  • Water (gradually added to batter for consistency)
  • Vegetable or Canola Oil (for frying)

Sauce

  • 3 tbsp Gochujang (Korean red chili paste)
  • 6 tbsp Ketchup
  • 1 1/2 tbsp Soy Sauce
  • 1 1/2 tbsp Garlic (minced)
  • 3 tbsp Sugar
  • 6 tbsp Corn Syrup


Instructions

  1. Prepare Chicken: Chop chicken thigh fillets into bite-size pieces. Place in a bowl and season with salt, pepper, 1 tablespoon minced garlic, and egg. Mix well and allow to brine in the refrigerator for at least 1 hour to tenderize and absorb flavors.
  2. Make Batter: After brining, add potato starch to the chicken pieces and gradually add water while mixing to create a batter. The batter should have a consistency that is neither too thick nor too runny—thick enough to coat the chicken but fluid enough to lift the bowl.
  3. First Fry: Heat vegetable or canola oil to 350°F (175°C). Fry the chicken pieces in batches for 5-6 minutes until cooked through and lightly golden. Avoid crowding the pan.
  4. Rest and Smash: Remove fried chicken from oil and let rest on a wire rack or paper towels for a few minutes. Gently smash each piece to create air pockets that will help achieve extra crispiness on the second fry.
  5. Second Fry: Increase the oil temperature to 375°F (190°C). Return the smashed chicken pieces to the hot oil and fry for 2 minutes until deeply crispy and golden brown. Remove and drain on a wire rack.
  6. Prepare Sauce: In a saucepan, combine gochujang, ketchup, soy sauce, 1 1/2 tablespoons minced garlic, sugar, and corn syrup. Simmer on low heat for a couple of minutes until the sauce thickens slightly and flavors meld.
  7. Toss Chicken: Quickly toss the freshly fried chicken in the warm sauce until fully coated.
  8. Serve: Plate the sauced chicken, optionally garnish with sesame seeds, and serve immediately to enjoy the perfect balance of crispy texture and spicy-sweet flavor.

Notes

  • Korean Fried Chicken is known for its ultra-crispy double-frying technique paired with a sweet and spicy sauce that makes it irresistibly delicious.

  • Use potato starch instead of regular flour for a lighter and crispier coating.
  • Keep an eye on oil temperature to maintain consistent frying results and avoid greasy chicken.
  • Serve immediately after coating with sauce to enjoy the contrast between crispy exterior and sticky spicy glaze.
