A lobster tail is a fast, foolproof piece of luxury once you know the one number that matters: pull it at 135 to 140°F. The mistake that ruins more lobster than anything else is overcooking, which turns that sweet, firm meat rubbery, so almost everything here is about hitting doneness and stopping.
You can boil, steam, bake, broil, or grill a tail, and each has its moment. The headline method is broiled with garlic butter for that steakhouse look, and the guide covers the other four, how to butterfly a tail, and which ones to buy.
5 Ways to Cook Lobster Tail
Pick the method by what you want, speed, tenderness, browning, or smoke. Whatever you choose, the timing rule of thumb is about one minute per ounce, and the finish line is the same: 135 to 140°F, opaque and firm.
| Method | Time (5–6 oz) | Best for |
|---|---|---|
| Broiling | 6–9 min | Browning and a restaurant look |
| Steaming | 5–6 min | The most tender, forgiving result |
| Baking | 10–12 min at 425°F | Even cooking and cooking for a crowd |
| Boiling | 5–6 min | Speed, then a bold butter sauce |
| Grilling | 5–8 min | Smoky flavor (watch it closely) |
Broiling is our headline method, so its full recipe is in the card below. Here is how the other four go.
Steaming
Bring 2 inches of salted water to a boil, set a steamer rack above it, add the tails, and cover tightly. Steam about one minute per ounce, then pull at 135 to 140°F. Steaming is the gentlest, most forgiving method and the one to choose the first time.
Baking
Heat the oven to 425°F, butterfly the shell and rest the meat on top, brush with butter and a little garlic, and bake 10 to 12 minutes for 5 to 6 oz tails, until the center reads 135 to 140°F. Baking cooks evenly and lets you do several tails at once for guests.
Boiling
Bring a large pot of well-salted water to a rolling boil (about 1 tablespoon of salt per quart), add the tails, and simmer gently about one minute per ounce, until the shells are bright red and the meat is opaque. It is the fastest route, best paired with a bold garlic-lemon butter.
Grilling
Butterfly the tails, brush with butter, and grill over medium-high, meat-side down first for a minute, then flip and baste until they reach 135 to 140°F. Grilling adds smoky char, but the window is short, so keep a thermometer close.
How to Butterfly a Lobster Tail
Butterflying does two jobs: it looks impressive and it stops the tail curling. With kitchen shears, cut down the center of the top shell to the base of the fin without cutting through the meat, then gently spread the shell and lift the meat so it rests on top, still attached at the tail. Lobster muscle contracts hard as it heats, and freeing it from the shell this way keeps it from clenching into a tight curl.
The One Rule: Pull at 135 to 140°F
Cook lobster to temperature, not to a timer. Pulled at 135 to 140°F and rested, the meat carries over to the USDA-safe endpoint of 145°F while staying tender, a target the safe-seafood-temperature guidance lines up with. Go much past that and the proteins tighten and wring out their moisture, which is exactly what "rubbery lobster" is.
Doneness signs back up the thermometer: the shell turns bright red and the meat goes from translucent to opaque and firm. If you are broiling for color, that quick blast of high heat also browns the buttered surface through the Maillard browning reaction, which is where the steakhouse look comes from.
How to Choose Lobster Tails
Cold-water tails, from Maine and Canada, have firmer, whiter, sweeter meat and are worth the small premium; warm-water tails are cheaper but can be softer and occasionally muddy in flavor, a difference rooted in the two lobster families. Whichever you buy, thaw frozen tails fully before cooking, overnight in the fridge or 30 to 60 minutes in cold water, so they cook evenly; the FDA seafood guidance covers safe thawing. Cooking a tail from frozen is the other road to rubbery.
What to Serve With Lobster Tail
Lobster tail is the classic surf-and-turf partner for a seared steak or a Wellington, but it also carries a plate on its own with drawn butter, lemon, and something green. Leftover meat is superb folded into a lobster risotto the next day.

Broiled Lobster Tail
Ingredients
- 2 lobster tails (5–6 oz each), thawed
- 3 Tbsp unsalted butter, melted
- 1 clove garlic, minced
- 1 tsp lemon juice
- 1/4 tsp paprika
- Salt, chopped parsley, and lemon wedges to serve
Instructions
- Thaw the tails overnight in the fridge. Position an oven rack about 6 inches below the broiler and heat the broiler to high.
- Butterfly each tail: with kitchen shears, cut down the top of the shell to the base of the fin without cutting the meat, then lift the meat and rest it on top of the shell.
- Stir the melted butter with the garlic and lemon juice. Brush it generously over the meat and season with salt and a light dusting of paprika.
- Broil about 1 to 1.5 minutes per ounce (roughly 6 to 9 minutes for 5 to 6 oz tails), until the meat is opaque and reads 135 to 140°F at the thickest point.
- Rest 2 to 3 minutes (it carries over to a safe 145°F), brush with more butter, and serve with parsley and lemon.
Notes
Lobster Tail FAQs
The questions that come up most: how long to cook a lobster tail, what temperature it should reach, why it turns rubbery, and how to butterfly it.
How long does it take to cook a lobster tail?
About one minute per ounce, so a 5 to 6 oz tail takes roughly 6 to 12 minutes depending on the method. Go by temperature rather than the clock: pull it at 135 to 140°F.
What temperature should a lobster tail be cooked to?
Pull it at 135 to 140°F at the thickest point and let it rest; it carries over to the USDA-safe 145°F. The meat should look opaque and feel firm.
Why is my lobster tail rubbery or tough?
It is overcooked. Past about 145°F the proteins tighten and squeeze out moisture, which is what makes lobster rubbery. Pull the tail early, at 135 to 140°F, and rest it.
How do you butterfly a lobster tail?
Cut down the top of the shell with kitchen shears to the base of the fin, without cutting the meat, then lift the meat and rest it on top of the shell. It looks impressive and stops the tail curling as it cooks.
Are cold-water or warm-water lobster tails better?
Cold-water tails from Maine and Canada are firmer, whiter, and sweeter, and worth the small premium. Warm-water tails are cheaper but can be softer and less clean in flavor.
Can you cook a lobster tail from frozen?
Thaw it first for even cooking: overnight in the fridge, or 30 to 60 minutes in a bowl of cold water. Cooking straight from frozen gives uneven, rubbery results.
