Melt 4 tablespoons of unsalted butter in a medium saucepan over medium heat. Stir in 1 teaspoon of smoked paprika, 1 teaspoon of garlic powder, and a pinch of salt and pepper. Let it simmer for 2 minutes until fragrant.

If using precooked king crab legs, wear kitchen gloves to crack the shells and extract the meat, keeping pieces bite-sized. This should take about 5 minutes.

In a large skillet, melt an additional tablespoon of butter and sauté the crab for 3-4 minutes until warmed through.

Remove from heat and stir in 2 tablespoons of fresh herbs and the juice of half a lemon.

Preheat your broiler. Toast the buns cut side up for 1-2 minutes until warm and golden.

Fill each toasted bun with the crab mixture and drizzle the garlic butter sauce over the top. Serve immediately.
