As someone who loves indulging in a perfectly cooked lobster, I often get asked how to know when it’s ready. Lobster can seem intimidating to prepare at home, but with a few techniques and visual cues, you’ll be serving up tender, delicious lobster in no time. In this comprehensive guide, I’ll walk you through the steps for cooking lobster and how to tell when it’s done.
Understanding Lobster Anatomy
Before jumping into cooking methods, it helps to understand lobster anatomy. A lobster consists of:
- The shell – The hard, protective outer layer
- The tail – The muscular part used for swimming
- The claws – The pincer-like appendages for grasping food
- The body – Contains the edible lobster meat
Knowing the different parts of a lobster helps when checking for doneness cues later.
Choosing Your Lobster
When buying a live lobster look for an active lobster that clamps its tail and moves its legs. Avoid lobsters that are sluggish or weak. Also look for lobsters that feel heavy for their size.
When cooking lobster at home, choose lobsters that are 1 to 1.5 pounds. Larger lobsters may be tough while smaller ones cook too quickly.
Preparing the Lobster
Before cooking, kill the lobster humanely by placing the tip of the knife about an inch behind the eyes and cutting straight down to split the head in half. Rinse the lobster under cold water. Some people prefer to split lobsters in half lengthwise before cooking for easier access to the meat.
Cooking Methods
There are several ways to cook lobster at home:
Boiling
Fill a large pot with enough salted water to cover the lobster. Bring to a rolling boil. Add live or killed lobsters head first and cover. Cook for 8-10 minutes for the first pound and 3 minutes for each additional pound.
Steaming
Place a steamer basket in a large pot and add a couple inches of water. Bring to a boil then add the lobster. Cover and steam for a similar time as boiling, around 10-15 minutes for a 1-1.5 pound lobster.
Grilling
Preheat and oil the grill. Split the lobster in half and place cut-side down. Grill for 2-3 minutes per side until the shell turns bright red. Brush with melted butter occasionally.
Baking
Preheat oven to 375°F. Place killed lobster on a baking sheet. Bake for 15 minutes per pound until the shell is bright red.
No matter the cooking method, the lobster is done when the shell turns bright red and the meat becomes opaque.
How to Tell When Lobster is Cooked
Here are some visual cues and techniques to check lobster doneness:
Shell Color
A bright red shell indicates the lobster is fully cooked. If there are still dark spots or a green/black tint, it needs more time.
Shell Texture
A cooked shell will feel hard and brittle. If it still feels soft or rubbery, it’s undercooked.
Tail Pull
Gently twist and pull the tail away from the body. It should detach easily when fully cooked. Resistance means it needs more time.
Meat Color
Lift the tail and check that the flesh is opaque and white, not translucent.
Float Test
Drop the tail into boiling water. It will float when fully cooked and sink if undercooked. Use this as a secondary check, not primary.
Poke Test
Poke the meat with your finger or a wooden skewer. It should feel firm, not mushy.
Temperature
Insert an instant-read thermometer into the thickest part of the tail. It should reach 140°F-145°F.
Doneness Cues for Parts
Check claws by cracking them open slightly to peek inside. The meat should be opaque white.
Split the body open and check the meat inside is fully opaque, not translucent.
If the tail is cooked but other parts aren’t, quickly submerge the underdone sections in boiling water to finish cooking.
Avoiding Overcooking
It can be tempting to cook lobster longer to make sure it’s done, but overcooking makes the meat rubbery. Follow the recommended cooking times and check often for visual doneness cues.
Err on the side of slightly underdone vs. overcooked. You can always cook it a minute or two longer if needed.
Letting Lobster Rest
Once cooked, transfer to a serving platter and tent loosely with foil. Letting it rest 5-10 minutes allows the meat to absorb any residual heat and makes it easier to extract the meat.
Serving Suggestions
Serve lobster with drawn butter, lemon wedges, or even drizzled with aioli. For a decadent meal, pair lobster with steak or creamy risotto.
Use any leftover lobster meat in pasta, salad, rolls, or bisque. Refrigerate leftovers and consume within 2 days.
Storing Cooked Lobster
- Refrigerate in an airtight container up to 2 days.
- Freeze lobster meat for 4-6 months.
- Do not store in direct contact with ice or water which can ruin the texture.
Reheating Lobster
- Steam briefly over boiling water.
- Warm gently in a sauce or soup.
- Bake in a hot oven for 4-5 minutes just until heated through.
- Microwave at 50% power in short bursts, checking frequently.
Avoid overcooking when reheating as the meat toughens. Only reheat once for best quality.
Common Mistakes
Watch out for these common mishaps when cooking lobster:
-
Undercooking due to underestimating the time needed, especially for larger lobsters.
-
Overcooking by boiling or steaming too long, making the meat rubbery.
-
Assuming it’s done based on the bright red shell alone. Always check the meat.
-
Not using a thermometer to confirm safe internal temperature.
-
Cooking too many lobsters at once which brings down the water temperature and extends cooking time.
-
Reheating improperly at high temperatures or repeatedly.
Key Takeaways
-
Look for active, lively lobsters when purchasing. Select 1-1.5 pound sizes for home cooking.
-
Cook via steaming, boiling, baking or grilling until the shell is bright red and meat is opaque white.
-
Check doneness by shell color, meat color, float test, and temperature. Cook to 140-145°F internally.
-
Avoid overcooking to prevent rubbery meat. Let rest before serving.
-
Refrigerate leftovers and reheat gently once. Freeze extra cooked meat.
With proper technique and visual checks, you can serve perfect lobster at home. Just avoid common mistakes like under or overcooking. Next time your dinner guests ask how you achieved tender, delicious lobster, share these foolproof tricks. Enjoy this impressive and tasty seafood meal.

HOW TO BOIL LOBSTER:
Choose a pot large enough to hold all the lobsters comfortably; do not crowd them. A 4- to 5-gallon pot can handle 6 to 8 pounds of lobster. Fill with water, allowing 3 quarts of water per 1-1/2 to 2 pounds of lobster. Add 1/4 cup sea salt for each gallon of water. Bring the water to a rolling boil. Add the live lobsters one at a time, and start timing immediately. Do not cover. Stir the lobsters halfway through cooking. Let the lobsters rest for 5 minutes or so after cooking to allow the meat to absorb some of the moisture in the shell.

HOW TO STEAM LOBSTER:
Choose a pot large enough to hold all the lobsters comfortably; do not crowd them. A 4- to 5-gallon pot can handle 6 to 8 pounds of lobster. Put 2 inches of seawater or salted water in the bottom of a large kettle. Set a steaming rack inside the pot and bring to a rolling boil over high heat. Add the live lobsters one at a time, cover the pot, and start timing. Halfway through, lift the lid (careful—the steam is hot) and shift the lobsters around so they cook evenly.

Cooked lobsters will turn bright red, but that’s not the best indicator of doneness, especially for large lobsters. They may still be underdone when the shell turns red. Jasper White recommends cooking lobsters for the recommended time, then cracking one open where the carapece meets the tail. If it’s done, the meat will have changed from translucent to white.
