Preheat your oven to 400°F and line a baking sheet with parchment paper.
Halve the baby potatoes and toss them on the baking sheet with olive oil, half of the sea salt, and half of the black pepper.
Roast the potatoes for 20 minutes, then move them to one side of the tray and add the trimmed asparagus.
Season the asparagus with the remaining salt and pepper, then roast everything for another 10 minutes until the potatoes are golden and the asparagus is tender.
While the vegetables finish, place a steamer basket in a large pot with 2 inches of water and bring to a boil.
Add the snow crab legs to the steamer basket, cover, and steam for 5 to 7 minutes until heated through.
In a small saucepan over low heat, melt the ghee and add the minced garlic and smoked paprika, sautéing for about 1 minute until fragrant.
Remove the ghee from the heat and stir in the fresh lemon juice and finely chopped parsley.
Serve the hot crab legs immediately with the zesty garlic ghee sauce for dipping, alongside the roasted potatoes and asparagus.
