Juicy, broiled Garlic Lemon Butter Lobster Tails with a golden, garlicky drizzle and bright lemon finish—special-occasion flavor in 30 minutes.

Butterflying lobster tails at home looks fancy but is absolutely doable. A quick snip up the shell lets the meat perch on top, where it cooks evenly, bastes in butter, and picks up gorgeous color under the broiler. The lemon-garlic pan drippings become an instant sauce, so every bite is luscious and bright.
Whether it’s date night or a celebratory dinner, this method delivers tender, opaque lobster (never rubbery) with minimal effort. Pair with a simple salad or asparagus, and you’ve got a steakhouse-level plate without leaving your kitchen.
What You Need to Make These Garlic Lemon Butter Lobster Tails
- Lobster tails (5–6 oz each) — Meaty, sweet; broil beautifully once butterflied.
- Unsalted butter — Divided; dots the tails as they cook and enriches the finishing sauce.
- Olive oil — Helps the marinade cling and promote even browning.
- Garlic — Pressed for maximum aroma in both marinade and sauce.
- Fresh lemon juice — Bright acidity that wakes up the rich butter.
- Dijon mustard — Subtle tang to balance sweetness.
- Parsley — Fresh, herby finish (plus extra for garnish).
- Sea salt & black pepper — Essential seasoning for clean, briny-sweet flavor.
Step-by-Step Garlic Lemon Butter Lobster Tails
- Butterfly the tails. With kitchen shears, cut up the top shell to the tail fan, snipping lightly into the meat. Flip and crack the thin underside ribs, then lift the meat out to sit on top, attached at the base.
- Position the rack. Broiler on high; place an oven rack so the meat will sit about 6 inches from the heating element.
- Mix the marinade. Stir parsley, garlic, Dijon, salt, pepper, olive oil, and lemon juice.
- Season & dot. Set butterflied tails in a 9×13 pan. Spoon marinade over the meat and dot each with small pieces of butter.
- Broil to just done. Broil 10–11 minutes for 5–6 oz tails (or until the thickest part is opaque white and reaches 145°F).
- Make the sauce. Pour pan drippings into a small saucepan, add remaining butter, simmer briefly, and remove from heat.
- Serve. Plate the tails, spoon over the warm garlic lemon butter, and garnish with parsley and lemon wedges.

FAQ: How do I butterfly lobster tails safely?
Use sharp kitchen shears and cut only through the top shell and just into the meat. Loosen the meat gently with your fingers so it sits on the shell without tearing—this ensures even cooking and a restaurant-style look.
FAQ: How can I tell when lobster is done without overcooking?
Look for firm, opaque white meat with no translucent spots. An instant-read thermometer should read 145°F in the center. If a tail is larger, add a minute at a time and recheck.
FAQ: Can I prep ahead?
Yes. Butterfly and marinate up to 2 hours in the refrigerator. Bring to room temp for 15 minutes before broiling to promote even cooking.
FAQ: No broiler—what’s my Plan B?
Bake at 425°F until opaque (about 12–15 minutes for 5–6 oz), then briefly broil 1–2 minutes for light browning. Keep a close eye to avoid overcooking.
What to Serve with Garlic Lemon Butter Lobster Tails
- Asparagus or broccolini tossed with olive oil, salt, and lemon zest.
- Garlic mashed or buttered new potatoes to catch extra sauce.
- Crisp salad (greens, cucumber, radish) with a lemony vinaigrette for balance.
Pro Tips for Lobster Tail Perfection
- Dry the meat. Patting the lobster dry helps browning and prevents the marinade from sliding off.
- Even distance = even doneness. Align tails so each sits the same distance from the broiler. Rotate the pan once if your oven browns unevenly.
- Don’t skip the drippings. Those buttery pan juices are liquid gold—turning them into sauce is your flavor multiplier.
Storage & Reheating
Lobster is best fresh, but leftovers can be refrigerated up to 2 days. Reheat gently: place tails in a covered skillet with a splash of water or butter over low heat just until warmed through (avoid boiling or microwaving on high, which toughens the meat). The garlic lemon butter keeps 3–4 days; melt and whisk before serving again.
Enjoy the sweet, delicate lobster with that bright, garlicky butter—simple technique, big payoff, and a plate that looks as good as it tastes.

Garlic Lemon Butter Lobster Tails
Ingredients
- 4 raw lobster tails approximately 5 to 6 ounces each
- 1 ½ tablespoons freshly squeezed lemon juice
- 1 tablespoon finely minced flat-leaf parsley with extra for finishing
- 1 teaspoon Dijon-style mustard
- 2 cloves fresh garlic crushed or pressed
- ¼ teaspoon fine-grain sea salt
- ⅛ teaspoon ground black pepper freshly cracked
- 1 ½ tablespoons extra-virgin olive oil
- 4 tablespoons unsalted butter divided into portions
Instructions
To Butterfly the Lobster Tails:
- Using sharp kitchen shears, carefully slice through the upper shell of each lobster tail, extending the cut down to the tail’s base. While cutting, slice slightly into the top portion of the flesh.
- Turn the tail over and gently crack the underside transparent ribs to help ease the shell open.
- With fingers and thumbs, gently part the shell and lift the lobster meat upwards, detaching it slightly from the shell while keeping the base connected. Rest the meat above the shell, exposing it for even broiling.
To Cook the Lobster Tails:
- Adjust the oven rack to the upper-third position so that the lobster meat will be situated about 6 inches from the broiler element. Preheat the broiler to high.
- In a mixing bowl, combine the chopped parsley, crushed garlic, mustard, salt, black pepper, olive oil, and lemon juice. Stir well to create a marinade.
- Set the prepared lobster tails into a roasting pan (either 9×13 or 8×12 inches). Spoon the marinade evenly over the exposed meat of each tail. Dot each with ½ tablespoon of butter, broken into small chunks and spread over the surface.
- Place the pan under the broiler and cook for 10 to 11 minutes, or until the meat turns opaque and white throughout. An instant-read thermometer should register 145°F in the thickest part of the tail. Once broiled, move the lobster tails to a serving dish and sprinkle with additional parsley if desired.
To Make the Garlic Lemon Butter Sauce:
- Pour the cooking juices from the roasting pan into a small saucepan. Add the remaining 2 tablespoons of butter and bring to a gentle simmer. Once melted and warmed through, remove from heat.
- Serve the sauce poured over the lobster tails or portion it into small ramekins for dipping.
