Preheat the oven to 375°F (190°C).
Place the king crab legs on a baking sheet.
In a small saucepan, melt the butter over low heat. Add the minced garlic, Creole seasoning, and lemon juice. Stir well.
Brush the seasoned butter over the crab legs, ensuring they are coated evenly.
Bake in the preheated oven for about 20-25 minutes, or until the crab legs are heated through.
Serve the baked crab legs with chopped chives or parsley sprinkled on top and lemon slices on the side.
Enjoy!
