Korean Fried Chicken Grilled Cheese Sandwich

Why Smash Chicken Thighs in a Tortilla Press?

Smashing boneless skinless chicken thighs does one important thing.

It increases surface area.

More surface area means:

• More crispy crust
• More sauce coverage
• Faster, more even frying
• A wider sandwich that is easier to eat

Instead of stacking thick meat vertically, you create a broad, thin piece of chicken that spans the bun. It eats like a proper sandwich, not a balancing act.

The tortilla press technique is trending for a reason. It works.

What Makes This Different From a Regular Korean Fried Chicken Sandwich?

• The chicken is smashed and wide
• The cheese forms a crispy skirt
• The sauce uses hot oil to bloom spices
• The slaw is creamy but still spicy and acidic
• It eats like a grilled cheese and a fried chicken sandwich combined

It pulls inspiration from Nashville hot technique and Korean fried chicken flavor.

If you have ever had a brunch grilled cheese at Dahlia Lounge in Seattle, you understand the cheese crust concept. This builds on that and pushes it further.

How to Make Korean Fried Chicken Grilled Cheese Sandwich

1. Press the Chicken

Place chicken thighs between parchment and press in a tortilla press until thin and evenly spread.

You want wide and uniform. Season lightly with salt.

2. Marinate

Whisk together:

• Buttermilk
• Hot sauce
• Salt

Add pressed chicken and marinate at least 30 minutes. Longer is better.

3. Make the Dredge

Combine flour, potato starch, salt, and black pepper.

When ready to fry, remove chicken from marinade and press firmly into dredge. Really squeeze it in. This creates those craggy ridges that fry up ultra crispy.

Let dredged chicken rest 10 minutes before frying.

4. Fry

Heat neutral oil to 350°F or 175°C.

Fry chicken until golden brown and cooked through. About 5 to 7 minutes depending on thickness.

Drain on a rack.

5. Make the Korean Fried Chicken Sauce

In a heatproof bowl combine:

• Gochujang
• Korean chili flakes
• Garlic powder
• Soy powder or soy sauce
• MSG
• Dijon
• Rice wine vinegar

Carefully ladle 4 to 6 ounces hot fryer oil into the bowl.

It will sizzle. That is good.

Whisk until glossy and emulsified.

Add fried chicken and toss until fully coated.

6. Make the Kimchi Slaw

In a large bowl combine:

• Shaved Napa cabbage
• Scallions
• Cucumber

In a separate bowl mix:

• Kewpie
• Sambal
• Kimchi base

Fold dressing into vegetables. Chill until ready to use.

7. Build the Grilled Cheese Base

Heat a skillet over medium.

Place brioche buns cut side down. Generously cover both halves and the surrounding pan with shredded Jack cheese. Let the cheese melt and spread beyond the bun edges.

This creates crispy cheese skirts.

Place sauced chicken thighs onto the bottom bun halves.

Transfer skillet to a 400°F or 205°C oven for 4 to 5 minutes until cheese is fully melted.

8. Finish

Remove from oven.

Top chicken with generous kimchi slaw.

Close with top bun.

Press gently.

Slice in half.

Eat immediately.

Pro Tips

• Use freshly shredded cheese. Pre shredded does not melt the same.
• Do not skip squeezing the dredge into the chicken. That texture matters.
• Rest the dredged chicken before frying. It helps adhesion.
• Blooming the sauce with hot oil deepens flavor instantly.

Frequently Asked Questions

Can I use chicken breast?

Yes, but thigh stays juicier and fries better when smashed thin.

Can I air fry it?

You can try, but you will lose some of the deep fry texture and oil bloom flavor.

What cheese works best?

Monterey Jack melts beautifully. Mozzarella works. Low moisture is best.
