How to Choose a Lobster Before Boiling
Page Contents
As a Maine lobster purveyor, we are biased. We believe Maine lobster is the best in the world, but not all Maine lobsters are created equal. Always choose a lively, feisty Maine lobster. Also try and buy a firm or hardshell lobster that is full of meat. Do not buy a lobster just before or after it has molted. It will not be full of meat. Soft-shell lobsters will always have less meat. Learn more about how lobsters molt.
Why Boil Lobster?
The shell of the lobster flavors the bubbling water, which in turn, flavors the lobster meat!
To boil or not to boil, that is the question. Of the different methods you can cook lobster, there are a few factors to consider.
Four Reasons to Boil Lobsters
Before we dive into how to boil lobster, let’s decide if this is the best method for cooking live lobsters.
- Best for cooking 4 or more lobsters at a time.
- Cooks lobsters more evenly than steaming.
- Makes it easier to remove the meat from the shell
- Cooks lobster faster than steaming.
Are you cooking lobsters for a large group? Boiling is one of the quickest ways to cook live lobster and the preferred method for cooking a bunch of lobsters at one time. The high, intense heat cooks the meat quickly when you boil lobster, causing it to pull away from the shell. Boiling lobsters will cook them more evenly and makes it easier to remove the meat out of the shell. But watch out and keep an eye on your lobster boil time to make sure you do not overcook your lobsters! If you are just cooking a few lobsters (1-4), steaming might be the better option.

When shucking the meat out of the lobster do it over the sink. The water inside the lobster will splat all over and make a mess. See how to shell a whole lobster.
Common Mistakes to Avoid While Boiling Lobster
- Do Not Boil a Dead Lobster: If a lobster has just expired and is still cold to the touch, add it to the pot; otherwise, avoid cooking, or the result will be mushy, inedible meat. For food safety and firm meat, always cook lobster alive. This is true for any cooking method, whether you are steaming, grilling, or even baking live lobster.
- Do Not Crowd the Pot: Choose a pot with lots of room. You want your pot to be big enough so when the water boils, it can circulate and cook all the lobsters evenly. If you have a small pot, simply cook your lobsters in small batches.
- Do Not Boil Too Long: Watch your cooking time. Many of the boiling instructions online are way too long. Overcooked lobster is rubbery lobster. This is especially true of select size and jumbo lobsters. We often hear that big lobsters are tough and small lobsters are more tender. This may be true if too much time is added to the cooking time. Home cooks also add too much time when cooking multiple lobsters. Also, be careful to adjust your time when cooking soft shell lobsters. A firm or hard-shell lobster will require a couple more minutes to cook than soft-shell lobsters. The hot water needs to penetrate the thicker, firmer shell.
What is the Best Way to Handle Live Lobster Before Boiling?
Now that you have decided to boil lobster let’s discuss how to handle your live lobsters. These clawed crustaceans can be a little frisky and feisty, and you want them to be!
To prevent any splash of hot water pick up the lobster by holding the upper side of the thorax between your thumb and middle finger. Hold the underside of the body with the legs facing away from you because the lobster has a tendency to flip the jointed tail, splattering water.
In addition, keep the rubber bands on the claws when you add them to the water. The only pinches should be stolen pieces of succulent lobster meat. You can cook more than one lobster in a pot as long as there is enough room and water to cover them. If you do not have a big enough pot, use two smaller pots or cook your lobsters in batches.
How are Lobsters Killed Before Boiling
Next up in the discussion of how to boil lobster is how to humanely dispatch live lobsters. This is a controversial topic, as some researchers claim lobsters may feel pain when cooked. The UK government says octopuses, crabs, and lobsters should be treated as sentient beings.
What we do know is that lobsters do not process pain like humans, as they have a simple, insect-like, decentralized nervous system. To reduce any suffering, it’s best to sedate the lobster in the freezer or an ice bath for 25 minutes before boiling. What’s more, when the lobster is chilled, it is much easier to handle than a flipping, thrashing lobster. Learn more about how to kill a lobster before cooking.

What is the Boiling Process to Boil Lobster?
- Pick a large pot that will accommodate your lobsters and allow them room without water overflowing. Fill the pot 2/3 of the way full and place it on the burner on medium-high heat.
- Bring the water to a boil and season with sea salt or kosher salt. Allow the salt to dissolve fully.
- Carefully place the lobsters one at a time headfirst into the boiling water, keeping their legs pointed away from you.
- Once you have added all of your lobsters, cover the pot and begin timing. Refer to the chart as you will cook the lobsters according to their weight.
- Check the lobsters to see if they are done. The easiest way to do this is to check their internal temperature. It should be between 135 and 140 degrees. Stick your instant-read thermometer in the underside of the tail, close to the body. You can also check by giving its antenna a tug. If it easily comes out, your lobster is done.
- Give the lobster a good cooling down. Either place them in a colander and run cool water over them or put them in an ice bath.

Bring the water to a rapid boil over medium-high heat. Add 2 tablespoons of kosher salt for each quart of water. If sea water is available skip the salt and use Triton’s gift. - Place the lobsters head first into the water.
Working one at a time, place your live lobsters headfirst into the boiling water. Make sure they are fully submerged. If your pot is large enough to accommodate multiple lobster, add the next. However, it’s better to use a couple of pots than risk overcrowding and over flowing. - Cover the pot immediately to maintain heat.
Adding the lobsters to the boiling water will drop the temperature. Cover the pot immediately and bring it back to a boil. - Set up a timer appropriate for your lobster size (see chart in this post).
As soon as the water is boiling, set your alarm. Don’t walk away from that pot but do get your butter melting. - Check to see if the Lobster is ready.
If you’re in doubt of whether or not your lobster is done, there are a couple of things you can do. First, the most reliable way is by checking the internal temperature. Use an instant read thermometer to make sure the lobster meat is between 135-140 degrees. Always stick it in the underside of the tail closest to the body.
Another way to tell if your lobster is done or not is by giving their antenna a firm tug. If it easy comes off, it’s done. - Cool down your lobsters.
As soon as your timer goes off transfer your lobsters to either a colander and run cool water over them or transfer them to an ice bath to stop the cooking.

How to Determine When the Lobster is Fully Cooked
The most important part of how to boil lobster correctly is knowing when the lobsters are done. When a lobster turns bright red or when the antennas can be easily removed can give some indication the lobster is cooked, but this is not always the case. The best way to tell if the lobster is cooked properly is to use an instant-read thermometer. Take the lobster’s tail temperature. You want to aim for about 135 degrees in the thickest part of the tail.
What if I Overcook My Lobster?
When in doubt, it’s always better to undercook your lobster since you can always add more time to the cook. If you overcook your lobster, there is no going back. You can’t remove cooking time, so just be cautious. Another option is to parboil lobsters before proceeding to grill them to get that kiss of fire.
Another common mistake is adding to the cooking time just because you are boiling more than 1-2 lobsters in the pot. The cooking time remains the same for properly boiling lobsters regardless of how many you cook. Also, keep in mind that when you add a large number of lobsters to the pot, it will instantly drop the heat. It’s better to cook them in batches. Just remember to bring your pot back to a rolling boil and regulate the heat. Happy cracking!
Tips for How to Boil Lobster
- Pick lively lobsters that are hardshell, Maine Grade A.
- Make sure that your pot is large enough so not to crowd the lobsters and prevent the water from spilling over. If you plan on boiling many lobsters, it is better to cook them in batches.
- If you do boil your lobsters in batches always allow the water to come back to a full rolling boil before adding the next lobsters in.
- If the water starts to boil over, lower the heat. You can also do this by adding ice cubes to quickly drop the temperature.
- Always temp-check your lobsters. The color of their shells alone isn’t the only indication of whether they are undercooked or overcooked.
- Always cook your lobsters to between 135 and 140 degrees. If you undercook your lobster, you can gently warm it in butter to bring it to temperature.
