Step‑by‑Step Instructions for Baked Lobster Tails with Garlic Herb Butter Sauce and Creamy Mashed Potatoes
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This temperature ensures your Baked Lobster Tails with Garlic Herb Butter Sauce will be perfectly cooked through and develop a beautiful, golden finish. As the oven warms up, get your baking dish ready, greasing it lightly to prevent sticking during the baking process.
Step 2: Prepare the Lobster Tails
Carefully use kitchen shears to cut the top shell of each lobster tail lengthwise, exposing the meat. Gently lift the lobster meat, allowing it to rest on top of the shell for even cooking and an appealing presentation. Place them in your prepared baking dish, ensuring they are arranged evenly for efficient heat distribution.
Step 3: Make the Garlic Herb Butter Sauce
In a small saucepan, melt 4 tablespoons of unsalted butter over medium heat. Once melted, add minced garlic, chopped parsley, chopped chives, lemon juice, and a sprinkle of salt and pepper. Stir the mixture for about 2-3 minutes until the garlic is fragrant but not browned, then brush half of this aromatic garlic butter generously over the lobster tails, reserving the rest for later.
Step 4: Bake the Lobster Tails
Place the prepared lobster tails in the preheated oven and bake for 12-15 minutes. You’ll know they’re done when the meat is opaque and firm to the touch. Keep an eye on them after about 10 minutes to ensure they do not overcook—perfectly baked lobster will have a nice sheen on the surface.
Step 5: Boil the Potatoes
While the lobster bakes, fill a large pot with salted water and add your peeled potatoes. Bring the water to a boil and cook for about 15 minutes until the potatoes are fork-tender. Drain them well and return the potatoes to the pot to steam off excess moisture—this will help create that creamy texture in your mashed potatoes.
Step 6: Mash the Potatoes
Using a potato masher, mash the drained potatoes until smooth. Gradually add in milk and sour cream, mixing until your desired creaminess is achieved. Season with salt and pepper to taste, ensuring the mashed potatoes are rich and flavorful. Keep them warm as you finish up with the lobster for a perfect pairing.
Step 7: Assemble and Serve
Once your lobster tails are beautifully baked, drizzle the remaining garlic herb butter sauce over the top for an extra flavor boost. Serve the succulent lobster alongside the creamy mashed potatoes on warmed plates, allowing everyone to enjoy this indulgent meal that brings restaurant-quality dining right into your home kitchen.

Expert Tips for Baked Lobster Tails
• Use Kitchen Shears: Safely cut the lobster shells with kitchen shears for a clean, precise opening without damaging the meat.

• Warm Potatoes Gently: After boiling, return potatoes to the pot to steam off moisture before mashing, ensuring your creamy mashed potatoes are velvety.
• Fresh Ingredients Matter: Opt for fresh garlic and lemon juice to elevate the flavors in your Baked Lobster Tails with Garlic Herb Butter Sauce—they make a significant difference!
• Adjust Your Seasoning: Taste and adjust the salt and pepper in both the lobster and mashed potatoes to suit your palate—don’t be shy!

Baked Lobster Tails with Garlic Herb Butter Sauce and Creamy Mashed Potatoes Recipe FAQs
How do I choose the best lobster tails?
Absolutely! Fresh is best when it comes to lobster tails. Look for tails that are firm, with a bright color and no dark spots or blemishes. If you’re going for frozen, ensure they’re completely thawed—overnight in the fridge is ideal for safe thawing.
What is the best way to store leftover lobster tails?
Very! After you’ve savored your delicious meal, store leftover lobster tails in an airtight container in the fridge for up to 1-2 days. This helps maintain the lobster’s moisture. If you think you won’t finish them soon, consider freezing: wrap each tail tightly in plastic wrap, followed by aluminum foil for up to 3 months.
Can I freeze the garlic herb butter sauce?
Yes, you can! To freeze your garlic herb butter sauce, allow it to cool and then transfer it to ice cube trays or a silicone mold. Once frozen, pop the cubes into a zip-top freezer bag. They’ll last for about 3 months and can be used directly from the freezer—just add them to your hot lobster tails right before serving!
What should I do if my lobster turns out overcooked?
Don’t worry! If you find your lobster tails overcooked, there’s still a chance to salvage the meal. Consider slicing the lobster into smaller pieces and mixing it into a creamy pasta or risotto, as the creaminess can help mask the dryness. Always keep an eye on the cooking time—12-15 minutes is key for tender, juicy lobster!
Can pets eat lobster leftovers?
Yes, but with caution! While plain lobster (without seasoning or butter) can be a treat for dogs, it should be given in moderation. Always remove the shell and serve in small quantities. It’s best to check with your veterinarian before sharing seafood with your furry friends.
How do I ensure my mashed potatoes remain creamy when reheating?
Absolutely! To achieve creamy mashed potatoes when reheating, transfer them to a pot, add a splash of milk (or cream), and gently reheat over low heat, stirring often. This will help restore their creamy texture and prevent them from drying out. Keep an eye on them to avoid burning!
