Before you start cooking your lobster tail, you'll need to prepare it properly. This involves cutting the shell and removing the vein, which can be done with kitchen scissors or a sharp knife.

Once your lobster tail is prepped, you can start cooking it in the oven.

The cooking time will depend on the size of your lobster tail, but as a general rule of thumb, you should cook a 6-ounce lobster tail for about 10-12 minutes at 425°F (220°C).

However, it's important to monitor the cooking process closely as variations in oven temperature or the size of the lobster tail can impact the cooking time.

Preparing Your Lobster Tail

Cooking lobster tail in the oven is a great way to enjoy this delicious seafood. To ensure that your lobster tail comes out perfectly, you need to prepare it properly. Here are the steps you need to follow:

Thawing Frozen Lobster Tails

If you are using frozen lobster tails, you need to thaw them before cooking.

The best way to do this is to place them in the refrigerator for 24 hours. If you don't have that much time, you can also thaw them in a bowl of cold water. Make sure to change the water every 30 minutes until the tails are fully thawed.

Preheating the Oven

Preheat your oven to 425°F (218°C) before you start preparing your lobster tail. This will ensure that the oven is hot enough to cook the lobster properly.

Seasoning the Lobster Tail

There are many ways to season your lobster tail, but a simple garlic butter seasoning works well.

To make garlic butter, mix melted butter with minced garlic, lemon juice, salt, pepper, and paprika. You can also add fresh parsley for extra flavour.

To prepare the lobster tail, use kitchen scissors to cut through the top of the shell lengthwise. Then, use your hands to gently separate the meat from the shell, but leave it attached at the base.

Brush the lobster tail with the garlic butter seasoning, making sure to get some of the seasoning in the cuts you made.

Place the lobster tail on a baking sheet and bake it for 12-15 minutes, or until the internal temperature reaches 145°F (63°C). Make sure to baste the lobster tail with the remaining garlic butter seasoning halfway through cooking.

Cooking and Serving

Baking the Lobster Tail

To bake lobster tails in the oven, preheat your oven to 425°F.

While the oven is heating up, prepare a baking sheet by lining it with parchment paper. Then, use kitchen scissors to cut the top of the lobster shell lengthwise, exposing the meat. Be sure to keep the shell intact.

Brush melted butter over the meat, and place the tails on the prepared baking sheet.

Checking for Doneness

To ensure that the lobster tail is fully cooked, use an instant-read thermometer to check the internal temperature. The meat should be firm and opaque, and the internal temperature should reach 140°F.

This should take around 12-15 minutes, depending on the size of the tails and the specific recipe.

Suggested Side Dishes

Baked lobster tails pair well with a variety of side dishes. For a healthy and delicious option, serve with steamed broccoli.

Alternatively, serve with rice for a filling and satisfying meal. Be sure to baste the lobster tails with melted butter while baking to ensure even cooking and a moist texture.

Overcooked lobster tails can become rubbery, so be sure to keep an eye on the cooking time to avoid this.
