There’s something irresistible about tiny, crisped bites of chicken that pack a serious punch of flavor. This Oven Fried Korean Popcorn Chicken takes the joy of snackable fried chicken and brings it into the oven for a lighter, fuss-free approach that still delivers crunch and sticky, savory-sweet sauce. Tender cubes of chicken soak in buttermilk, get a robust cornflake crust, and then meet a glossy, garlicky gochujang glaze finished with toasted sesame and green onions. It’s perfect for game day, parties, or a weeknight when you want something a little special with minimal hands-on frying.
Why you’ll love this recipe

This version keeps the deep-fried character but moves the cooking into the oven so you get crispy edges, juicy centers, and less oil splatter. The cornflake crust creates a satisfying texture contrast, while the marinade ensures each cube stays moist. The sauce — a blend of soy, honey, rice vinegar, ginger, garlic, and gochujang — is balanced and addictive: tangy, sweet, salty, and spicy all at once. Sprinkle on toasted sesame seeds and sliced green onions, and you’ve got a snack that disappears fast.

Make-ahead and swap notes
You can cut the chicken up to a day ahead and keep it refrigerated in an airtight container. If you don’t have buttermilk, stir 1 tablespoon lemon juice or white vinegar into 1 cup milk and let sit five minutes to thicken; use that in place of the buttermilk. The recipe calls for low sodium soy sauce to keep the overall seasoning balanced; regular soy sauce will work, but taste the glaze before serving and adjust honey or vinegar if needed. Gochujang can range from mild to very spicy; start on the lower end if you’re unsure.
Step-by-step instructions

- Marinate the chicken: Place the 2 pounds boneless chicken breasts, cut into 2 inch cubes, into a bowl or resealable bag. Pour 1 cup buttermilk over the chicken and gently stir or squeeze to coat every piece. Let the chicken sit for at least 20 minutes at room temperature or up to 4 hours in the refrigerator. This softens the meat and helps the coating adhere.
- Preheat and prepare baking surface: Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper and set a wire rack on top of the sheet if you have one — the rack helps air circulate and keeps the bottoms crisp. Lightly brush the rack or parchment with extra virgin olive oil where the chicken will touch.
- Make the cornflake coating: In a shallow wide bowl or pie plate, combine 3 cups finely crushed corn flakes and 3 tablespoons whole wheat or all-purpose flour. Shake in a few grinds of black pepper and stir to combine evenly. Finely crushed corn flakes should have a mix of small crumbs and a few tiny flakes to create an even crisp crust.
- Coat the chicken: Remove the chicken from the buttermilk in batches, allowing excess to drip off, and transfer the pieces into the cornflake mixture. Press each cube gently into the cornflake mixture so the crumbs adhere well and form a modest crust. Place the coated chicken pieces on the prepared wire rack or directly on the parchment-lined baking sheet with a little space between them to allow hot air to circulate.
- Brush with olive oil: Lightly brush the tops of the coated chicken pieces with extra virgin olive oil. This step helps the crust brown and crisp in the oven without deep frying.
- Bake until golden and cooked through: Bake the chicken at 425°F (220°C) for 15–18 minutes, flipping once halfway through if they are crowded on a single layer. The pieces should be golden brown and register 165°F (74°C) at their thickest point. Exact bake time depends on your oven and the size of the cubes, so check one piece early to prevent overcooking.
- Make the glaze while the chicken bakes: Combine 1/2 cup low sodium soy sauce, 3 tablespoons honey, 1–2 tablespoons gochujang (start with 1 tablespoon and add more to taste for heat), 2 tablespoons rice vinegar, 1 inch fresh ginger (grated), 2 cloves garlic (grated), and 2 tablespoons toasted sesame oil in a small saucepan. Warm the mixture over medium-low heat and whisk until honey dissolves and the glaze is glossy, about 2–3 minutes. Remove from heat and taste; adjust heat or sweetness by adding a little more gochujang or honey as desired.
- Toss the baked chicken in the glaze: When the chicken pieces are cooked through and have crisped, transfer them to a clean bowl. Pour the warm glaze over the chicken and gently toss so each piece is evenly coated. If you prefer a stickier finish, return the glazed chicken to the baking sheet and broil for 1–2 minutes, watching carefully so the glaze caramelizes without burning.
- Finish and serve: Sprinkle 3 tablespoons toasted sesame seeds over the glazed chicken and toss lightly. Transfer the popcorn chicken to a serving platter and scatter chopped green onions over the top for bright color and fresh bite. Serve immediately so the crust stays crisp and the glaze is warm and glossy.
Serving suggestions

This Oven Fried Korean Popcorn Chicken is a wonderful finger food. Serve it with pickled vegetables, cucumber slices, or a simple cabbage slaw to cut the richness. It also pairs well with steamed rice or a bowl of mixed greens dressed with a light sesame vinaigrette. For a party tray, include extra glaze on the side and some lime wedges for squeezing.
Tips for the crispiest bites
- Don’t overcrowd the baking sheet. Give each piece a little breathing room so hot air can crisp all sides.
- Using a wire rack on the sheet allows air to circulate under the chicken and prevents sogginess.
- Press the cornflake crumbs firmly onto each piece so the coating stays in place during baking and tossing.
- If you like extra crunch, pulse the corn flakes for a few more seconds to create a finer, more even crumb.
- Brush with olive oil rather than drizzling — a brush gives you control and helps avoid greasy spots.
Storing and reheating
Leftovers keep well in the refrigerator for up to 3 days. Store the chicken in an airtight container separate from any extra glaze to preserve crispness. To reheat and restore crunch, place the pieces on a baking sheet and heat in a 375°F (190°C) oven for 8–10 minutes, or until warmed through. You can reheat glazed chicken for a minute or two under the broiler to revive the shine, but watch closely so the glaze doesn’t burn.
Notes on ingredients and the glaze
The balance of sweet, salty, tangy, and spicy in the glaze is what makes this recipe sing. Low sodium soy sauce keeps the saltiness in check so the honey and rice vinegar can shine. Gochujang adds a savory depth and gentle heat; adjust it based on your spice preference. Grated fresh ginger and garlic bring brightness and an aromatic backbone, while toasted sesame oil and seeds add that nutty finish that pairs so well with Korean flavors.

It’s snackable, shareable, and full of flavor without the hassle of frying. The technique is simple: marinate, coat, bake, and toss in a bold glaze. The result is crunchy, tender, and utterly addictive—so be prepared to make a second batch.
