Put the prepped crab legs on the grill, or on a baking sheet if heating them in the oven.  Just a note here:  King Crab Legs come already cooked so you are basically just reheating them and adding that butter sauce.  Heating them up will take about 20 minutes.

It’s time to make that scampi butter.


Start by chopping up the garlic.  Then, mix the butter, garlic, salt, pepper and Calabrian chili flakes in a bowl or reusable container.  (just in case there is any leftover).  Use your taste buds to decide how much of the chili flakes you use.  If you like it really spicy, add more.  Less spicy, add less.

Nutritional information is only an estimate. The accuracy of the nutritional information for any recipe on this site is not guaranteed.


  • 4 Lbs. of King Crab Legs, (they already come cooked in the seafood department)
  • 1/2 Cup of unsalted butter
  • 3-4 Large garlic cloves, finely minced
  • 1 Tsp. Salt and black pepper to taste
  • 1 Tsp. Calabrian Chili Flakes (more or less to taste)
  • Zest of lemon for butter, and wedges of lemon to serve


  • Heat your grill to medium high heater. You can make these in the oven just heat to 350 degrees.
  • Using scissors, cut long slits in the crab leg shells and/or break the crab legs at the joints. This allows the heat to penetrate and allows the scampi butter to get into all the nooks and cranies!
  • Put crab legs on the grill or on a baking sheet in the oven for about 20 minutes.
  • Meanwhile, make the scampi butter. Mix all the ingredients in a small bowl and put on a large disposable baking sheet on the grill (for easy clean up). Let that butter melt down. In making in the oven, microwave the butter for 20 seconds until melted then add to the baking sheet in the oven. Toss your crab legs in the butter coating everything. Turn several times for another 2-3 minutes.
  • If grilling, serve those legs right on the buttery baking sheet. If in the oven, I take the legs off the baking sheet, put them on a platter and drizzle that garlic butter all over the crab legs. Serve with lemon wedges and seafood forks and bibs! The forks get all the meat and the bibs will save your shirt!!!! LOL Enjoy.
