Be sure crab legs are fully thawed (or if frozen, add a few minutes to the cook time).
Preheat oven to 350 degrees F and line a baking pan with aluminum foil or parchment paper.
Place legs (with shell on) on a jelly roll pan or large baking sheet. Put up to 4 legs on a pan. (You may put two pans in the oven but you may have to increase the cooking time).
Bake for 25-35 minutes depending on the size of them. At 25 minutes check them--they should be hot/warmed though, a little steamy.
Use kitchen shears or crab crackers to open the shells and remove the meat. Serve dipped in melted butter.
