Butter Basted and Smoked King Crab Legs Recipe

Butter Basted and Smoked King Crab Legs Recipe

Crab legs are definitely a treat for a celebratory meal or an awesome summer gathering on the patio. Crab legs are almost always pre-cooked when they are very fresh and flash frozen to preserve them before heading to market. If you live in Alaska and have access to fresh king crab, you are fortunate. If not, Alaskan king crab legs found in the freezer section of your market are really quite good. But, you will want to reheat them before serving. They are perfect for smoking in a Masterbuilt Smoker where you can infuse the flavor of smoke and seasonings into the crab meat.

Choosing and Purchasing Crab Legs

The best crab legs your money can buy are from king crabs. Most of our domestic king crabs are harvested from the Bering Sea off the coast of Alaska. These waters are rough and cold, requiring much fortitude to fish for them. The crabs are quite large with hard shells and sweet tasting meat.

The legs of king crabs are large enough to rest nicely on a smoker rack. There are different varieties of king crab available. The three basic types are the golden or brown king, the blue king, and the red king. The golden king crab is commonly smaller and more abundant. Blue king crabs are larger and often have giant right claws. All of these descriptions are for king crab that has been processed and cooked. Live king crabs carry different shades of colors.

King crab is measured by how many crab legs it takes to make 10 pounds. A package labeled 12 – 14 indicates that there is an average of 12 to 14 legs per 10 pounds. Claws are not counted when making this weight count. I am not sure why that is. Package sizes can range from 6 – 9 and up to 21 – 24, the latter being the smaller legs.

The Goodness of King Crab Legs

King crab is very lean. This is likely due to the environmental conditions of their natural habitat. The cold northern sea waters make for some robust and hardy sea life. One crab leg is approximately 5 ounces and only 130 calories. Most of those calories are protein, approximately 85 percent. King crab has no carbohydrates, so the remaining 15 percent of the calories are fat. Most of the fat content is polyunsaturated and includes plenty of heart healthy omega-3 fatty acids.

Crab is a good source of folate, vitamin A, vitamin B-12, and vitamin C. It is also a notable source of calcium, magnesium, and selenium. Consuming crab can benefit your red blood cell production, your metabolism, your bones, and your overall immune system function.

It should be noted that crab does contain a fair amount of sodium, some of which is released during the initial cooking process. If you are restricting sodium in your diet, reduce the amount of salt you use in the smoking recipe outlined here.

Butter Basted and Smoked King Crab Legs Recipe

For this recipe you will want to defrost your crab legs in the refrigerator overnight. Don’t be tempted to defrost them in the microwave as this might compromise the texture of the meat by slightly cooking it.

Yield: 6
Prep Time: 10 minutes
Cook Time: 35 minutes
Total Time: 45 minutes

Crab legs are definitely a treat for a celebratory meal or an awesome summer gathering on the patio. They are perfect for smoking in a Masterbuilt Smoker.


  • 10 lbs of king crab legs
  • 1 lb (4 sticks) butter (salt free if restricting sodium)
  • Juice from 1 whole large lemon
  • 1/4 cup jarred or homemade crab boil seasoning (a recipe follows) or Old Bay seasoning
  • 4 cloves of garlic, finely minced

For serving:

  • Melted butter
  • Lemon wedges
  • Cocktail sauce or aioli


1. Defrost the crab legs in your refrigerator overnight.

2. Place mild wood chips, such as alder or maple, in the tray of your smoker. Fill the water bowl 1/2 way with water or beer. Preheat the smoker to 225°F with the vent open and the door closed.

3. In a medium pot over medium-high heat, put your butter, lemon juice, seasoning mix, and minced garlic. Stir everything together as the butter melts.

4. In a large pan, place the crab legs. To allow for smoke to better get to the meat, you can crack each leg in a couple of places, if you like. Pour the seasoned butter mixture over the legs to coat them evenly. Place the legs on the smoker racks and close the door or lid. Reserve any leftover butter for basting. Smoke the crab legs for 30 to 40 minutes brushing butter on the legs every 10 minutes. Be mindful that the crab is already cooked, so don’t be tempted to overcook it as it could become dry and stringy.

5. Melt some more butter, cut some lemon wedges, and place some cocktail sauce or aioli in a bowl while the crab is smoking.

6. When the legs are hot and steamy, place them on a platter and serve immediately with butter, lemon wedges, and cocktail sauce or aioli. Have shell crackers, forks, and plenty of napkins available.
