  • 5 to 6 lbs fresh king crab legs thawed
  • 8 tablespoon butter
  • 1 shallot minced
  • Salt
  • Cilantro
  • Parsley
  • Red pepper flakes
  • Lemons


Prep the grill:

  • Make sure your crab legs are thawed
  • Prep your grill for indirect heat by building a hot side of the grill with the coals or burners heating on side of the grill surface and the other side left cooler.

Grill the crab legs:

  • Place the crab legs over the direct heat side of the grill and allow the legs to grill to heat them up.
  • Rotate the crab legs as needed to prevent burning as they warm
  • Move the legs to the cooler side if needed, making sure all of the king crab legs are heated through.

Make the chimichurri butter:

  • Add a small pan to the hot side of the fire and add the shallots.
  • Saute until softened.
  • Carefully move to the cooler side of the grill.
  • Add the butter to melt.
  • Add the parsley, cilantro, and red pepper flakes.
  • Stir to combine
  • Add the salt and season to taste.


  • Char the lemons in the hot side of the grill
  • Split the crab legs with a knife and baste with the butter
  • Serve with charred lemons and additional butter for dipping.


This recipe would work for snow crab legs, stone crab, or any fresh crab that's already been steamed you have and want to grill. The chimichurri butter is great on all of it!
