There’s something magical about the scent of grilled chicken wafting through a backyard on a summer evening. It instantly takes me back to long family weekends spent gathered around a worn picnic table, the air filled with laughter, chatter, and the occasional sizzle from the grill. My uncle was the designated grill master, always armed with his secret stash of sauces and spices. He believed that chicken needed a bold glaze – not too sweet, not too spicy, but just right – to shine on the grill. This recipe is inspired by those backyard cookouts where the flavor was always bigger than the occasion.

INGREDIENTS YOU’LL NEED:

8 boneless, skinless chicken thighs
1/3 cup soy sauce
1/3 cup brown sugar
1 tablespoon hot sauce
1 tablespoon olive oil
1 tablespoon Dijon mustard
1 tablespoon garlic, minced
1/2 teaspoon crushed red pepper flakes
1/2 teaspoon black pepper

HOW TO MAKE SWEET AND SPICY GRILLED CHICKEN THIGHS:

STEP-BY-STEP INSTRUCTIONS:

Step 1: Mix up the marinade
In a medium bowl, whisk together the soy sauce, brown sugar, hot sauce, olive oil, Dijon mustard, minced garlic, red pepper flakes, and black pepper. The mixture should look glossy and smell irresistible – a mix of tangy, sweet, and garlicky goodness.

Step 2: Marinate the chicken
Place the chicken thighs in a large zip-top bag or a shallow dish. Pour the marinade over the top, making sure each piece is well coated. Seal it up and let it marinate in the fridge for at least 2 hours – but if you can swing overnight, the flavor payoff is totally worth it.

Step 3: Fire up the grill
Preheat your grill to medium-high heat. If you’re using charcoal, let the coals ash over before cooking. Lightly oil the grill grates to prevent sticking – a paper towel dipped in oil and held with tongs works great.

Step 4: Grill the chicken
Place the marinated chicken thighs on the grill and cook for about 5–6 minutes on each side, or until the internal temperature reaches 165°F and the edges get beautifully charred. Brush with leftover marinade during the last few minutes for an extra sticky glaze (just make sure it’s cooked through).

Step 5: Rest and serve
Let the chicken rest for a few minutes off the grill before slicing. This helps the juices redistribute, so every bite stays tender and flavorful. Serve it up with grilled veggies, a side of rice, or a fresh salad – it’s a guaranteed crowd-pleaser.

HELPFUL TIPS:

Marinate longer if you can: Overnight marinating makes the flavors pop even more.
Double the batch: These reheat beautifully and make great leftovers for lunch the next day.
No grill? No problem: You can cook these in a grill pan or even under the broiler if the weather isn’t cooperating.
Make it milder or hotter: Adjust the amount of hot sauce and red pepper flakes based on your spice preference.

FREQUENTLY ASKED QUESTIONS:

Can I bake this instead of grilling?
Absolutely. Preheat your oven to 425°F and bake the marinated chicken thighs on a lined sheet pan for 20–25 minutes, flipping halfway through.

Can I use bone-in chicken?
Yes, but you’ll need to adjust the cook time. Bone-in thighs typically need 8–10 minutes per side on the grill.

Is this recipe freezer-friendly?
Definitely. You can freeze the raw chicken right in the marinade for up to 2 months. Thaw overnight in the fridge before grilling.

STORAGE INSTRUCTIONS:

Store any leftovers in an airtight container in the fridge for up to 4 days. Reheat gently in the microwave or in a skillet over low heat. You can also enjoy the leftovers cold, sliced up over a salad or tucked into wraps.
