To begin, preheat your oven to 400°F (200°C), and while that's heating up, let's prep our crab legs. Rinse them under cold water, and pat them dry with some paper towels - don't worry, this is the most tedious part of the process! Next, season those crab legs with your favorite spices and herbs, whether that's a squeeze of lemon, a sprinkle of Old Bay, or something entirely different.
Now it's time to get our oven-steaming station set up. Grab a large baking dish, and add about an inch of water to the bottom - this is what's going to create that perfect steam. Arrange your crab legs in a single layer, cover the dish with aluminum foil, and you're ready to roll!
