Cooking crab legs in the oven is a delicious and easy method. You can preheat the oven to 375°F, place the crab legs on a baking sheet, and brush them with melted butter and your favorite seasonings. Cover the baking sheet with foil and bake for about 15-20 minutes. How do you usually enjoy your crab legs—plain, or with a dipping sauce? Do you have any special occasion in mind for this meal?
