Grilling chicken thighs on a gas grill is a great way to achieve juicy, flavorful meat with a delicious smoky char. However, knowing the correct grilling time is essential to ensure the chicken is fully cooked without drying it out. Cooking time varies based on factors such as whether the thighs are boneless or bone-in, grill temperature, and marination.
In this guide, we will cover everything you need to know about grilling chicken thighs on a gas grill, including preparation steps, grilling techniques, recommended cooking times, and expert tips to get the best results.
Preparing Chicken Thighs for the Grill
Before you start grilling, proper preparation ensures that the chicken thighs cook evenly and develop the best possible flavor. Follow these steps:
Choosing the Right Cut: Bone-In vs. Boneless
- Bone-in chicken thighs: These take longer to cook but offer richer flavor and juiciness due to the bone retaining heat and moisture.
- Boneless chicken thighs: These cook faster and are easier to handle on the grill, making them a convenient choice.
Marination and Seasoning
Marinating your chicken thighs enhances their flavor and tenderness. A good marinade should include:
- Acid: Lemon juice, vinegar, or yogurt to tenderize the meat.
- Oil: Olive oil or vegetable oil to keep the chicken moist.
- Seasonings: Garlic, onion powder, smoked paprika, black pepper, and salt for depth of flavor.
- Sweetness (optional): Honey or brown sugar can create a nice caramelized crust.
For best results, marinate chicken thighs for at least 30 minutes, but ideally 4-8 hours in the refrigerator.
Preheating the Grill
- Set your gas grill to medium-high heat (375°F to 400°F).
- Clean and oil the grates to prevent sticking.
- Allow the grill to preheat for 10-15 minutes before placing the chicken on it.

Grilling Time for Chicken Thighs
The cooking time for chicken thighs depends on whether they are boneless or bone-in.
Boneless Chicken Thighs
- Grill Temperature: 375°F to 400°F
- Cooking Time: 6-8 minutes per side
- Total Time: 12-16 minutes
- Internal Temperature Goal: 165°F
Bone-in Chicken Thighs
- Grill Temperature: 350°F to 375°F
- Cooking Time: 10-12 minutes per side
- Total Time: 20-25 minutes
- Internal Temperature Goal: 175°F for optimal tenderness
Using a Meat Thermometer
To ensure chicken is cooked safely, always use a meat thermometer:
- Insert it into the thickest part of the thigh without touching the bone.
- The USDA recommends a minimum of 165°F, but bone-in thighs taste best when cooked to 175°F-180°F.
Flipping and Rotating
- Flip chicken thighs once halfway through cooking.
- For even cooking, rotate thighs around the grill to avoid hot spots.
- If using a gas grill with multiple burners, use direct heat for searing, then switch to indirect heat to finish cooking.
Tips for Perfectly Grilled Chicken Thighs
1. Avoid Flare-Ups
Excess fat from chicken thighs can cause grill flare-ups, leading to burnt spots. To prevent this:
- Trim excess fat before grilling.
- Use indirect heat for thicker cuts.
- Keep a spray bottle of water nearby to control flare-ups.
2. Use Indirect Heat for Thick Thighs
For bone-in thighs or extra thick pieces:
- Start with high direct heat (2-3 minutes per side) to create a nice sear.
- Move to indirect heat and close the grill lid, allowing the chicken to finish cooking without burning.
3. Baste with Sauce at the Right Time
- Apply BBQ sauce or glaze only during the last 5 minutes of cooking.
- This prevents sugar-based sauces from burning and sticking to the grates.
4. Let the Meat Rest
- After removing from the grill, let the chicken rest for 5-10 minutes.
- This allows juices to redistribute, making the chicken more tender and flavorful.
Serving Suggestions
Grilled chicken thighs pair well with a variety of sides and sauces. Here are a few ideas:
- Classic BBQ Plate: Serve with coleslaw, baked beans, and cornbread.
- Grilled Veggies: Pair with zucchini, bell peppers, or asparagus.
- Rice or Potatoes: Enjoy with seasoned rice, mashed potatoes, or roasted sweet potatoes.
- Dipping Sauces: BBQ sauce, honey mustard, garlic aioli, or chimichurri.
Common Mistakes to Avoid
1. Cooking at the Wrong Temperature
- Too high: The outside burns before the inside cooks.
- Too low: The chicken may dry out before reaching the correct internal temperature.
2. Not Using a Thermometer
Guessing doneness can lead to undercooked or overcooked chicken. Always check with a thermometer.
3. Skipping the Resting Period
Cutting chicken too soon lets the juices escape, leading to drier meat.
4. Overcrowding the Grill
Leave space between pieces for even heat distribution and proper airflow.
Conclusion
Grilling chicken thighs on a gas grill is an easy and rewarding way to prepare a delicious meal. By following the recommended grilling times, using a thermometer, and implementing key grilling techniques, you can achieve perfectly juicy and flavorful chicken every time. Whether you’re making a quick weeknight dinner or grilling for a summer barbecue, mastering the art of grilling chicken thighs will impress your family and friends.
Happy grilling.
