How to Grill Crab Legs

To grill these king crab legs, I start by splitting them in half down the length of the legs. Some fish mongers sell the legs already split, some will happily split them for you, or if you’ve got strong hands and great kitchen shears, you can split them yourself. Having the legs split is a key for optimal results on the grill. It allows all of the flavor from the fire and the seasoned butter to penetrate the sweet crab meat.

If you are using snow crab legs, you can follow the same time and temperature guidelines written in the recipe below, but toss the entire crab leg clusters in the seasoned butter before grilling instead of splitting the smaller legs. Serve with more of the seasoned butter for dipping. Oh, and lots and lots of napkins.

How Long to Grill Crab

I recommend cooking your crab legs on a low temperature, around 225 degrees F for about 25-30 minutes. As all commercially sold crab is pre-cooked in the US, all you need to do is reheat the crab meat. I use indirect heat (meaning no fire or coals directly under the crab legs) with the overall temperature of my grill hovering in that 225 degrees F zone.

Smoked Crab Legs

If you want to add smoke, you can make your grilled crab legs on a smoker or add a foil packet of wood chips with holes poked all around the pouch on top of the fire in your grill. These smoked crab legs are fantastic with mild woods like pecan or alder for a mellow smoke flavor. If you want that smoke to be more prominent, I recommend using a stronger wood like oak or hickory. Remember, these smoked crab legs are only in that grill for 30 minutes, but they will take on a bit of smoke.

How Much Grilled Crab Legs Per Person

If you are serving the crab as the main course, I would plan on 1 1/2 to 2 pounds per person. Remember, you lose a lot in the weight of the shells (which are discarded). If you are serving as a side dish, like with my Garlic Butter Prime Rib, then you can plan around 1 pound per adult.
