Reverse sear on charcoal for perfect doneness

Yes, reverse sear is the way to go for thick steaks on charcoal. It’s the only reliable way to get edge-to-edge even doneness without a gray band or raw center.

The short version: Cook the steak indirectly (not over coals) until it’s about 20-25°F below your target, then sear it directly over hot charcoal for 60-90 seconds per side.

Here’s what that looks like in practice.

Set up your grill for two zones: pile all the charcoal on one side for searing, leave the other side empty. Target 225-250°F ambient temp on the indirect side if you can, but 300°F works fine too. Don’t overthink the exact temp—just keep it below 350°F.

Place the steak on the cool side, lid closed, and cook until internal temp hits about 110-115°F for medium-rare (125-130°F final). This will take 30-45 minutes depending on thickness and wind. Use a probe thermometer; don’t guess.

Once it’s there, pull the steak off, open the vents fully, and let the coals get screaming hot (the chimney starter approach works best). Pat the steak dry—moisture is the enemy of a crust. Sear directly over the coals, flipping every 30-60 seconds, until you get a nice crust and the internal temp climbs to 125-130°F. Rest it for 5 minutes minimum.

The beauty of this method: you can cook the indirect part hours ahead if you want, then just sear at dinner time. I’ve done that for guests and it’s foolproof.

A thick steak deserves this method—thin ones don’t. Save the reverse sear for anything over 1.5 inches.
