You can find them at some markets or at your local fishmonger. Look at the lobster tank and look for the ones that look healthy. Avoid lobsters that are too still or have holes or black marks on the shell.

Step 3. Soak the lobsters in water

Take one lobster by the body at a time and dip them headfirst into the boiling water. Cover the pan.

Don't let the water overflow. If there's not enough room in the pan for all the lobsters you've bought, cook in two batches

Step 4. Cook the lobsters

When the water boils again, start recording the cooking time. 200 g lobsters should cook for about 15 minutes, 500 g for 20 minutes and 1 kg lobsters for 25 minutes. Lobsters are cooked when the shells turn bright red. Remove them from the pan and place on a plate to dry and cool.

It is important to time the cooking time as lobsters can turn red before they are completely cooked

Place each lobster on a serving plate. Serve with a small cup of melted butter, a nutcracker to break the claws, and a bowl for discarded shells. See How to Eat Lobster for a tutorial on which parts of lobster are good to eat.

Method 2 of 2: Grilled or Roasted Lobster Tails

Cook a Lobster Step 6

Step 1. Heat the grill

Prepare to cook lobster tails by heating the grill over medium high heat. The entire surface of the grill must be warm.

If you're roasting your lobster tails instead of grilling, turn on your oven's browning function to heat it up well

Step 2. Cut the lobster tails in half to open them

Using sharp kitchen scissors, cut lengthways in the middle of the softest part of the hull. Insert metal skewers lengthwise through the meat of the lobster tails. Brush the tails with oil on both sides.

Step 3. Grill the lobster tails

Place on the grill with the cut side down and cook for about 5 minutes or until the hooves turn bright red. Turn tails, cut side up. Sprinkle the minced garlic, salt and pepper on the lobster meat and drizzle with a few tablespoons of butter. Grill for another 5 minutes or until the meat is no longer translucent.

If you are roasting lobster tails instead of grilling, complete this process in the oven. Grill them with the cut side down for 5 minutes, remove from the oven, season with garlic, salt and pepper and butter and return to the oven for another 5 minutes

Step 4. Serve the lobster tails

Place each on a plate and serve with melted butter and lemon slices.


  • Adding salt to boiling water to cook whole lobster makes it less likely that the animal's minerals will be released due to the concentration gradient.
  • You can buy frozen or fresh lobster tails. Frozen ones will take a little longer to cook.


  • The hepatopancreas, the green paste found in lobster, works like the lobster's liver and pancreas. It can be consumed and is considered a delicacy for its flavor. However, it is also much more likely to have toxins in it than in other parts of the lobster. Lobsters caught during red tides are likely to contain high levels of toxins and the hepatopancreas of these lobsters should not be consumed.
  • To avoid being pinched by a lobster, do not remove the rubber bands from the claws until the lobster is fully cooked.
