Korean BBQ Grilled Chicken Sandwich Ingredients
For the Pickles
• Whole Seedless Cucumber – Adds crunch and freshness; can substitute with Persian cucumber.
• Rice Vinegar – Provides tanginess for quick pickles; no direct substitute, but apple cider vinegar works well.

• Sugar – Balances acidity in the pickles; can substitute with honey or agave syrup.
• Ice – Rapidly cools the pickling liquid for the best texture; essential for quick pickles.
For the Sauce
• Sesame Oil – Adds nutty flavor; can substitute with vegetable oil, though flavor depth will diminish.
• Grated Garlic – Fresh flavor and aroma; powdered garlic can be a substitute but will alter texture.
• Grated Ginger – Brightens the sauce; ground ginger can be used if fresh is unavailable.

Step‑by‑Step Instructions for Korean BBQ Grilled Chicken Sandwich
Step 1: Pickle Preparation
Begin by slicing the whole seedless cucumber and placing the pieces in a clean container. In a small saucepan, combine rice vinegar, salt, and sugar, bringing it to a gentle simmer over medium heat until the sugar dissolves, about 3-4 minutes. Remove from heat, cool slightly, and add ice to the mixture before pouring it over the cucumbers. Seal the container and refrigerate for at least 4 hours to achieve vibrant pickles.
Step 2: Korean BBQ Sauce
In a medium saucepan, heat 2 tablespoons of sesame oil over medium heat. Once hot, sauté the grated garlic and ginger until fragrant, about 1-2 minutes. Stir in the low sodium soy sauce, gochujang, brown sugar, honey, and a splash of rice vinegar. In a separate bowl, mix cornstarch with a bit of water to create a slurry, then whisk it into the sauce. Simmer the mixture until it thickens to a glossy finish, around 5-7 minutes, then remove from heat and let cool.
Step 3: Sriracha Mayo
In a small bowl, combine ½ cup of mayonnaise with 2 tablespoons of sriracha, 1 teaspoon of sesame oil, and a splash of soy sauce. Use a whisk or fork to mix until the ingredients are well incorporated and smooth. This creamy, spicy sriracha mayo will add a zesty kick to your Korean BBQ Grilled Chicken Sandwich, so set it aside for assembly.
Step 4: Grilling Chicken
Preheat your grill using a two-zone setup for indirect heating, heating one side to high and leaving the other side cooler. While the grill is warming, season boneless skinless chicken thighs generously with your Korean BBQ rub. Place the thighs on the high-heat side and grill for about 4-5 minutes per side, ensuring a nice sear. Once they’re beautifully browned, move them to the cooler side and cook until the internal temperature reaches 165°F, about another 10-12 minutes. Brush your BBQ sauce over the chicken during the final few minutes of cooking.
Step 5: Assembly
Carefully remove the grilled chicken from the grill and let it rest for a few minutes before slicing. While it rests, split your sandwich buns or rolls in half and spread a generous layer of sriracha mayo on each side. Layer the sliced BBQ chicken onto the bottom bun, add a few pieces of pickles, and top with the other half of the bun. Serve your Korean BBQ Grilled Chicken Sandwich warm, and get ready to savor the delightful blend of flavors!

Korean BBQ Grilled Chicken Sandwich Recipe FAQs
How do I know if my cucumbers are ripe for pickling?
Absolutely! Look for whole seedless cucumbers that are firm and have a vibrant green color, without any dark spots or wrinkles. If you’re using Persian cucumbers, they should also be crisp and firm to the touch. Fresh cucumbers ensure that your pickles have that delightful crunch and refreshing flavor!
What’s the best way to store the components of the sandwich?
Very good question! Store the grilled chicken in an airtight container in the fridge for up to 4 days. Your homemade pickles should be kept in a sealed jar and can last about 5 days. The BBQ sauce can also be refrigerated for 5 days in a sealed container, ensuring that everything stays fresh and delicious for your next assembly!

Can I freeze the grilled chicken thighs?
Absolutely! If you want to enjoy the Korean BBQ Grilled Chicken Sandwich later, you can freeze the grilled chicken for up to 3 months. Just allow it to cool completely, then wrap it tightly in plastic wrap or place it in an airtight freezer bag. When you’re ready to eat, simply thaw it in the refrigerator overnight and reheat on the grill or stovetop until heated through.
What if my BBQ sauce is too thick?
No worries at all! If your BBQ sauce ends up too thick, simply whisk in a bit of water or additional low sodium soy sauce until it reaches your desired consistency. If you like, you can also heat the sauce gently on the stove while stirring in the water for an even distribution. This way, you can achieve that perfect saucy texture for your sandwich!
Can I make the pickles ahead of time?
Most certainly! In fact, I recommend making the pickles at least a day in advance. This allows the cucumbers to absorb all the tangy flavors, enhancing their taste and crunch. You can prepare them and store them in the fridge for about 5 days, making them a fantastic component to have ready for quick assembly during your busy week!
Are there any dietary considerations I should keep in mind?
Yes, absolutely! If you’re considering allergies or dietary preferences, make sure to check for any gluten issues as the low sodium soy sauce can be swapped out with tamari for a gluten-free option. Additionally, if serving to pets, please remember that garlic and onions (typically present in sauces and marinades) can be harmful to dogs, so keep that in mind when preparing!
