In a small saucepan over low heat, melt the butter. Once melted, add the minced garlic and sauté for about 2 minutes until it becomes fragrant. Stir in the fresh parsley and lemon juice, then season with a pinch of salt and a dash of pepper. Remove the saucepan from heat and set it aside.
Clean the snow crab legs if necessary. You can use kitchen shears to cut through the shells to make it easier to access the meat.
Place the crab legs on a baking sheet in a single layer. Brush each leg generously with the garlic butter sauce, making sure to get some inside the shells for extra flavor.
Put the baking sheet with the crab legs into the preheated oven. Bake for approximately 15-20 minutes or until the crab meat is heated through and the edges become slightly crispy. Keep an eye on them to avoid overcooking.
Once done, transfer the baked snow crab legs to a serving platter. Drizzle any remaining garlic butter sauce over them for that extra burst of flavor. Serve hot with lemon wedges on the side.
