Creating delicious baked crab legs is straightforward when following these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Baking Sheet: Line a rimmed baking sheet with aluminum foil for easy cleanup.
3. Arrange the Crab Legs: Place the crab legs on the prepared baking sheet in a single layer.
4. Make the Garlic Butter: In a small bowl, mix together the melted butter, minced garlic, lemon juice, and old bay seasoning.
5. Brush the Crab Legs: Generously brush the crab legs with the garlic butter mixture, ensuring they are well-coated.
6. Cover with Foil: Cover the crab legs with another piece of aluminum foil to trap steam during baking.
7. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes, until heated through.
8. Uncover and Broil: For added crispiness, remove the top layer of foil and broil for an additional 2-3 minutes.
9. Garnish: Remove from the oven and garnish with freshly chopped parsley.
10. Serve: Immediately serve the crab legs with additional garlic butter and lemon wedges on the side.
