Garlic Butter King Crab Leg Skillet with Parmesan

This garlic butter king crab leg skillet is the ultimate seafood splurge, ready in under 30 minutes. Split Alaskan king crab legs are seared in a screaming-hot cast iron pan, basted with a foaming garlic herb butter, and finished with a snowfall of aged Parmigiano-Reggiano and a squeeze of charred lemon.

The result is sweet, tender crab meat with a savory, nutty crust and a bright, smoky finish. It's a restaurant-worthy dinner that feels special enough for a celebration but simple enough for a weeknight.

King crab legs are a delicacy that needs little more than butter and heat. This recipe lets the crab shine by using a hot cast iron skillet to caramelize the edges while the garlic butter keeps the interior moist and sweet.

The Parmesan adds a salty, umami crunch, and the charred lemon cuts through the richness with a citrusy pop. Perfect for a special occasion or a cozy seafood feast, this skillet dish is both impressive and surprisingly easy to make.

Ingredients

Why this recipe works

The high heat of a cast iron skillet sears the crab meat quickly, creating a lightly browned crust while keeping the inside tender and juicy.

Basting with garlic herb butter continuously coats the meat, infusing it with flavor and preventing it from drying out. The butter also helps the Parmesan melt into a golden, savory crust.

Splitting the crab legs lengthwise exposes the meat directly to the heat and the butter, so every bite is seasoned and succulent.

Grated Parmigiano-Reggiano melts into the butter, forming a rich, nutty sauce that clings to the crab. The charred lemon adds a bright, smoky acidity that balances the richness of the butter and cheese.

Notes and substitutions

Choose Alaskan king crab legs that are already cooked (frozen or thawed) for the best texture and safety. They are typically sold precooked, so you're just reheating them. If using raw crab, adjust cooking time and ensure the internal temperature reaches 145°F (63°C).

A box grater is ideal for shredding the Parmesan into light, fluffy pieces that melt quickly. Use a 12-inch cast iron skillet for even heat and enough space to arrange the legs in a single layer. If you don't have a cast iron skillet, a heavy stainless steel pan works, but avoid nonstick as it won't get as hot.

• unsalted butter: salted butter (reduce added salt)
