Ingredients

Why this recipe works

The two-step cooking method—searing first, then baking—is the key to perfectly cooked lobster tails. Searing the flesh-side down in a hot cast-iron skillet creates a flavorful Maillard crust that locks in natural juices. This initial blast of high heat also gives the meat a beautiful golden color and a slight caramelization that enhances its sweetness.

After flipping, the oven finish at 425°F (220°C) gently cooks the meat through without overcooking, ensuring it remains tender and succulent. The butter basting adds moisture and flavor, coating the meat in a rich, garlicky sauce that seeps into every crevice.

Butterflying the tails—cutting the shell and lifting the meat onto the top—exposes the flesh to direct heat, allowing it to cook evenly and quickly. This technique also creates a natural 'boat' for the garlic butter, so the sauce surrounds the meat as it bakes.

The combination of cast-iron heat and butter basting mimics the effect of a professional steakhouse, delivering a dish that is both impressive and foolproof. The result is lobster that is never rubbery, always buttery, and ready in minutes.

Notes and substitutions

For the best results, use cold-water lobster tails, such as Maine or Canadian, which have sweeter, more tender meat. If using frozen tails, thaw them overnight in the refrigerator before cooking. The size of the tails will affect cooking time; adjust the baking time accordingly, aiming for an internal temperature of 140°F (60°C).

A cast-iron skillet is ideal for this recipe because it retains heat well and creates a beautiful sear. If you don't have one, a heavy stainless-steel skillet will work, but avoid nonstick, which won't get as hot.

The garlic butter is the flavor backbone of this dish. Use fresh garlic for the best aroma, and mince it finely so it melts into the butter. Smoked paprika adds a subtle smoky depth, while fresh lemon juice brightens the richness. If you prefer a spicier kick, add a pinch of cayenne pepper. Chopped parsley adds color and freshness at the end. You can prepare the butter mixture ahead of time and keep it in the refrigerator, but bring it to room temperature before using so it pours easily.

• smoked paprika: regular paprika or a pinch of cayenne for heat
• fresh lemon juice: bottled lemon juice, though fresh is brighter
• unsalted butter: salted butter; reduce added salt elsewhere
• Maine lobster tails: any cold-water lobster tails (such as Canadian or Australian)
