Grilled Spicy BBQ Chicken Thighs Ingredients
For the Chicken
- Boneless Skinless Chicken Thighs – The juiciness of thighs makes them perfect for grilling; try chicken breasts for a leaner option.

- Salt and Black Pepper – Essential for enhancing flavor; adjust to your taste preference.
For the BBQ Sauce
- Butter – Brings richness to the sauce; swap coconut oil for a dairy-free version.
- Yellow Onion – Adds sweetness and depth; shallots work well as a substitute.

- Apple Cider Vinegar – Balances the sauce with acidity; you can use white vinegar or lemon juice instead.
- Water – Adjusts sauce thickness; chicken stock can enhance the flavor even more.
- Ketchup – The sweet base of the BBQ sauce; low-sugar versions or homemade options are healthier.
- Paprika – Adds smokiness and vibrant color; smoked paprika intensifies flavor.
- Sriracha and Sambal Oelek – Provide that essential heat; swap for another hot sauce or decrease for milder spice.
- Chili Powder and Mustard – Elevate the sauce’s complexity; choose mustard type based on your taste—yellow or Dijon.

Step‑by‑Step Instructions for Grilled Spicy BBQ Chicken Thighs
Step 1: Prepare the BBQ Sauce
In a medium saucepan over medium heat, melt 2 tablespoons of butter. Add one finely chopped yellow onion, sautéing until it becomes translucent, about 5 minutes. Stir in 3 cloves of minced garlic, cooking until fragrant, around 1 minute. Then, mix in the remaining sauce ingredients, bringing the mixture to a gentle simmer for 15 minutes until it thickens and becomes rich in flavor.
Step 2: Prepare Chicken
While the sauce simmers, take 2 pounds of boneless skinless chicken thighs and pat them dry with paper towels. Drizzle them with olive oil, ensuring each piece is evenly coated. Season generously with salt and black pepper to enhance the flavor. This preparation will ensure that the chicken thighs not only absorb the spices but also stay juicy while grilling.
Step 3: Grill the Chicken
Preheat your grill to medium-low heat, about 350°F. Once ready, place the chicken thighs smooth-side down on the grill grate. Cook them for about 20 minutes, turning every 3-4 minutes to achieve even cooking. Look for juices to run clear and an internal temperature reading of 165-170°F for perfectly grilled spicy BBQ chicken thighs.
Step 4: Baste with Sauce
In the final minutes of grilling, generously baste each chicken thigh with the homemade spicy BBQ sauce using a brush. This adds a beautiful glaze and depth of flavor. Allow the sauce to caramelize slightly; it should become sticky and fragrant as it cooks, intensifying the taste of your grilled spicy BBQ chicken thighs.
Step 5: Rest and Serve
Once grilled to perfection, remove the chicken thighs from the grill and let them rest on a cutting board for about 5 minutes. This resting period allows the juices to redistribute, ensuring each bite remains tender and moist. Serve your juicy grilled spicy BBQ chicken thighs with additional sauce on the side and enjoy the delightful flavors at your next family gathering!

How to Store and Freeze Grilled Spicy BBQ Chicken Thighs
Fridge: Store cooked chicken in an airtight container for up to 4 days to maintain freshness and flavor.
Freezer: Freeze grilled chicken in freezer-safe bags or containers for up to 3 months. For best results, remove excess air to prevent freezer burn.
Reheating: Reheat in the microwave or oven; for oven reheating, cover with foil and warm at 350°F for about 15-20 minutes until heated through.
Serving Suggestions: Enjoy your reheated grilled spicy BBQ chicken thighs on their own or with a fresh side salad to create a quick, satisfying meal.

Expert Tips for Grilled Spicy BBQ Chicken Thighs
Temperature Control: Keep the grill on medium-low heat; high flames can dry out the chicken, while low heat allows for juicy, tender thighs.
Use a Thermometer: Invest in an instant-read thermometer to avoid cutting into your chicken before it’s fully cooked; this retains moisture for perfect grilled spicy BBQ chicken thighs.
Baste Smartly: Apply sauce during the last moments of grilling to prevent burning; the sugar in the sauce can caramelize too quickly if added too early.
Resting Time: Allow the grilled chicken to rest for about 5 minutes before serving; this helps lock in the juices for a super moist bite.
Adjust Spice Levels: Taste your BBQ sauce as you prepare it and adjust the sriracha and sambal oelek to fit your family’s preferred heat level.

Grilled Spicy BBQ Chicken Thighs Recipe FAQs
How do I choose ripe chicken thighs?
Absolutely! For the best grilled spicy BBQ chicken thighs, look for those that are plump and have a fresh, pink color. Avoid pieces with dark spots or off-putting odors. Fresh chicken thighs should feel moist but not sticky. Always check the “sell by” or “use by” dates when purchasing.
How should I store leftover grilled chicken?
Once cooled, store your grilled spicy BBQ chicken thighs in an airtight container in the refrigerator for up to 4 days. It’s best to refrigerate them within two hours of grilling to maintain flavor and texture. Ensure they are completely cooled before sealing to avoid condensation inside the container.
Can I freeze grilled chicken thighs?
Absolutely! Freezing is a great way to extend the life of your grilled spicy BBQ chicken. Place the cooled thighs in freezer-safe bags or containers, removing as much air as possible. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw them in the fridge overnight before reheating.
What if my chicken thighs are dry after grilling?
Very common! If your grilled spicy BBQ chicken thighs turn out dry, it may be due to overcooking. Always use an instant-read thermometer to check for doneness, as chicken should reach an internal temperature of 165-170°F. If they are already cooked, try serving them with extra BBQ sauce or consider soaking them in broth for a few minutes to help reintroduce moisture.
Can I make this recipe gluten-free?
Yes! This recipe can easily accommodate gluten-free diets. Simply substitute Worcestershire sauce with a gluten-free soy sauce, and check that your ketchup is also gluten-free. Additionally, double-check any spices to ensure they are free from gluten cross-contamination.
Are these chicken thighs safe for pets?
While it’s tempting to share your grilled spicy BBQ chicken thighs with your furry friends, it’s best to avoid giving them any with sauces, as many ingredients (like onions and certain seasonings) can be harmful to pets. Plain, cooked chicken (without skin or seasoning) is generally safe for dogs and cats in moderation.
