Lobster is the crown jewel of seafood cooking — a celebratory ingredient that commands premium prices and deserves precise preparation. Overcooked lobster becomes tough, rubbery, and loses the sweet, delicate flavor that makes it special. The Lobster Cooking Calculator uses the classic rule of approximately 1 minute per ounce (or 8–12 minutes per pound depending on method) to give you exact cooking times based on lobster weight and cooking method.
The traditional rule for boiling live lobster is approximately 10 minutes per pound for the first pound, plus 3 minutes for each additional pound — though a simpler approximation of 1 minute per ounce (boiling) and 1.5 minutes per ounce (steaming) is widely used by lobster shacks and seafood restaurants. Steaming takes 2–3 minutes longer than boiling at equivalent weights because steam transfers heat slightly less efficiently than boiling water, but steaming is considered by many to produce more flavorful, less waterlogged meat.
Grilling and broiling lobster (split in half, flesh-side down for grill; shell-side down for broil) takes 8–12 minutes and imparts smoky char notes that complement the sweet meat. Baking stuffed lobster — a New England tradition — takes 15–25 minutes at 400°F depending on weight. In all methods, lobster is done when the internal temperature of the tail meat reaches 145°F (63°C) and the shell has turned bright red.
Meat yield in a whole lobster is approximately 25% of the total live weight. A 1.5 lb lobster yields about 6 oz of edible meat (tail, claws, knuckles, legs). This is important for recipe planning — if a recipe calls for 8 oz of lobster meat, you need approximately two 1.5-lb lobsters or one 2.5-lb lobster.
Boiling: approximately 8 min for 1 lb, 10 min for 1.5 lb, 12 min for 2 lb, scaling up. Steaming: 2 min longer than boiling at each weight. Grilling/broiling split: 8–12 min depending on size. Baking: 15–25 min at 400°F. Safe internal temp: 145°F in tail meat. Meat yield: approximately 25% of live body weight.
Shell color (bright red) and antenna pull-out (slides out easily) are traditional visual doneness cues. Verify 145°F in the thickest part of the tail. Claws take slightly longer to cook than the tail — ensure claws are opaque and white. Do not overcook: 5 extra minutes on a 1.5 lb lobster produces noticeably rubbery meat.

Classic boiled lobster. 10 min in heavily salted boiling water. Yields ~0.38 lbs (6 oz) meat. Plunge in ice water after cooking to stop carryover.

2 lb lobster split in half, grilled shell-up first 3 min then flesh-up 7 min. Baste with garlic butter. Yields ~0.5 lbs (8 oz) meat.
The shell should be bright red throughout and the antennae should pull out easily. The tail meat should be opaque white, not translucent. Internal temperature of the tail at the thickest point should reach 145°F (63°C). Do not use shell color alone — it turns red before the meat is fully cooked.
Fill a large pot with enough water to fully submerge the lobster (at least 1 gallon per 2 lbs of lobster). Salt generously — 1 tablespoon of sea salt per quart of water, or use seawater if available. Bring to a full rolling boil before adding lobster.
Both produce excellent results. Steaming is gentler and many cooks believe it produces sweeter, less waterlogged meat since the lobster is not submerged. Boiling is faster and more consistent for multiple lobsters. Steaming requires a large pot with a rack and tight-fitting lid.
Approximately 25% of a whole lobster's live weight is edible meat. A 1.5-pound lobster yields about 6 oz of meat (tail, claws, knuckles). The tail typically provides the most meat, followed by the claws, then the knuckles (the joint between claw and body).
Tail meat, claw meat, knuckle meat (the joint between claws and body), and leg meat are all edible. The green tomalley (liver) is edible but may contain contaminants — consumption is a personal choice. The coral (red roe in females) is edible and considered a delicacy.
The most widely accepted humane method: place the lobster in the freezer for 30–45 minutes to anesthetize it, then plunge a sharp knife through the head just behind the eyes. Some jurisdictions require licensed slaughter methods. Many cooks simply plunge the lobster head-first into boiling water.
Yes. Thaw overnight in the refrigerator for best results. From frozen: add 5–7 extra minutes to boiling time, or bake at 400°F for 25–30 minutes until 145°F. Thawed lobster tails cook as follows: 1 min per oz boiling, 10–12 min broiling for a 6-oz tail.
Classic drawn butter (clarified butter with lemon) is the simplest and most traditional. Brown butter with capers and herbs elevates the presentation. Garlic butter with fresh herbs is excellent for grilled lobster. Béarnaise or hollandaise sauce are classic accompaniments for baked whole lobster.
A 1.5-pound lobster is a generous single serving as a main course. A 2-pound lobster is a very generous single portion. For a shared appetizer, one 1.5-pound lobster feeds 2 people. For lobster bisque or pasta, plan on 1 pound live weight per serving of finished dish.
Chardonnay (particularly white Burgundy or Sonoma Chardonnay) is the classic pairing for butter-dressed lobster. Its rich texture and minerality complement the sweet meat beautifully. Champagne or quality Blanc de Blancs is equally excellent. Avoid tannic reds which clash with shellfish's sweetness.
