Baked Lobster Tails Ingredients
For the Lobster Tails

• Fresh Parsley & Chives – These herbs add brightness; dried versions can be used if necessary (just half the amount).
• Lemon Juice – This adds a refreshing zesty balance; vinegar can work as a substitute in a pinch.
• Salt & Pepper – Key for seasoning; adjust according to your taste and preference.
For the Creamy Mashed Potatoes
• Potatoes – Yukon Gold is perfect for fluffiness; russets are a great alternative if you prefer.
• Milk – Use any milk or dairy-free alternative to create that creamy consistency in your mash.

Step‑by‑Step Instructions for Baked Lobster Tails with Garlic Herb Butter Sauce and Creamy Mashed Potatoes
Step 1: Prep Lobster Tails
Using kitchen shears, carefully cut the top shell of each lobster tail lengthwise, stopping just before the base to keep the meat attached. Gently pull the lobster meat up and out of the shell for an elegant presentation. This preparation creates a beautiful display and allows the meat to soak up the flavors of the garlic herb butter sauce while baking.
Step 2: Make Garlic Herb Butter
In a small saucepan, melt half of the butter over medium heat. Stir in the minced garlic, freshly chopped parsley, chives, lemon juice, and season with salt and pepper. Let this mixture simmer for about 2-3 minutes, allowing the flavors to blend beautifully. Reserve half of this aromatic garlic herb butter for basting the lobster tails later during baking.
Step 3: Bake Lobster Tails
Preheat your oven to 375°F (190°C). Brush the prepared lobster meat generously with the garlic herb butter mixture. Place the lobster tails on a baking sheet lined with parchment paper and bake in the preheated oven for 12-15 minutes. You’ll know they are done when the meat turns opaque and firm to the touch, showcasing a delightful golden color on top.
Step 4: Prepare Creamy Mashed Potatoes
As the lobster bakes, peel and chop your potatoes into even chunks. Boil them in a pot of salted water for about 15 minutes or until fork-tender. Drain the potatoes and return them to the pot. Mash them with the remaining butter, milk, and sour cream until you achieve a creamy, fluffy consistency, adjusting with more milk if necessary for your desired texture.
Step 5: Serve and Assemble
Once the lobster tails are perfectly baked, remove them from the oven. Drizzle the reserved garlic herb butter over the lobster meat for added flavor. Serve on a plate alongside the creamy mashed potatoes, garnishing the dish as you wish with fresh herbs for an extra dash of color and elegance. Enjoy the comforting and luxurious experience of your Baked Lobster Tails with Garlic Herb Butter Sauce and Creamy Mashed Potatoes!

Expert Tips for Baked Lobster Tails
