BBQ Chicken Thighs on Charcoal: How Long You Need

Grilling chicken thighs over charcoal brings out an unbeatable smoky flavor. 

But when it comes to timing, it’s not always clear how long they need on the grill to cook perfectly — juicy inside, crispy outside, and safely done.

In this guide, we’ll break it all down simply: how long to BBQ chicken thighs on charcoal, what temperature to aim for, and how to know when they’re ready.

How Long to BBQ Chicken Thighs on Charcoal?

Bone-in, skin-on chicken thighs take 30 to 35 minutes to cook over charcoal at medium heat (350–400°F).

If you're grilling boneless thighs, expect 20 to 25 minutes total.

Here’s a basic timeline:

• First 5–7 minutes: Place the thighs skin-side down over direct heat to crisp up the skin.

• Next 15–20 minutes: Move to indirect heat and close the lid. Flip halfway through.

• Final 5–10 minutes: Move back to direct heat for a last sear, if needed.

👉 Always check internal temperature: Chicken thighs are done at 175°F to 185°F.

That’s a bit higher than for breasts, but it’s what makes them tender and juicy — not dry.

Direct vs. Indirect Heat Matters

When using charcoal, two-zone grilling is key.

• Direct heat = directly above the coals (hot!)

• Indirect heat = off to the side, where heat circulates but doesn’t burn

Start your thighs over direct heat to get that crispy skin, then shift them to indirect heat to finish cooking slowly. 

This gives you control — and avoids burnt outsides with raw insides.

If you’re not sure how to set up a two-zone grill, it’s simple:

• Pile your coals to one side only.

• Cook over the hot side, then move to the cooler side.

Pro Tip: Keep Your Grill Clean

Nothing ruins chicken like burnt-on gunk or flare-ups. 

That’s why it’s important to scrape your grill before cooking.

If you’re looking for a safe and durable way to do it, the Easy Function Bristle Grill Scraper is a great pick. 

It fits most grate types, doesn’t break or fall off, and tucks easily into your BBQ tool bag. 

Just heat the grill and scrape — safe and simple.

Skin-On vs. Boneless: Which Cooks Faster?

• Bone-in, skin-on thighs: 30–35 minutes

• Boneless, skinless thighs: 20–25 minutes

The bone slows cooking but adds flavor. 

Skin crisps up nicely but can cause flare-ups. 

Watch for dripping fat — move the meat away from flames if needed.

Want faster results? 

Try pounding the boneless thighs to an even thickness for quicker, more even grilling.

How to Know They're Really Done?

Don’t trust time alone — use a meat thermometer.

• Insert into the thickest part (not touching bone)

• Thighs are safe and tender at 175°F–185°F

• Juices should run clear, not pink

Unlike chicken breasts, thighs actually get juicier at higher temps. 

So don’t stop at 165°F. 

Let them climb a little higher for that perfect bite.

Add Smoke for Extra Flavor

Charcoal already gives great taste — but if you want deeper flavor, toss a chunk of hickory, applewood, or mesquite on your coals. 

Let it smolder before adding the chicken.

Or for an easier option, try a BBQ smoking guide magnet to pick the right wood for your meat. 

The Easy Function Smoking Guide Magnet shows exactly which woods match with poultry and more — great for beginners or pit pros.
