How to Conduct an Effective Lobster Boil

December 15, 2024

South Louisiana’s Cajun seafood boils are world-famous. Much more than just a delicious and hearty meal, seafood boils are all-day events for friends and family to enjoy together. Good food and good company—you can’t beat it.

While lobster isn’t traditionally the star of the show, it’s a great way to change up the classic Louisiana crawfish boil. If you’re in the mood to try something new, we highly recommend giving lobster a try. After all, lobsters are basically just big crawfish!

Follow these steps to host your boil like a pro.


1. Gather Your Ingredients

A Cajun lobster boil should be a larger-than-life feast! Make sure you have enough ingredients so everyone can eat their fill (and then some). You’re going to want at least one fresh lobster for each guest. For each lobster, you should also have at least 2-3 cobs of corn and 5-6 potatoes. You can eye the other ingredients:

  • Artichokes
  • Celery
  • Onions
  • Garlic
  • Lemons
  • Bay leaves

While the lobsters will provide plenty of protein, you can also add crawfish, shrimp, crab, and/or andouille sausage if you want to go all out with a seafood boil. However, in this guide, we’re just going to focus on how to conduct a lobster boil.

For the seasoning, we recommend 6 pounds in an 80 to 100 qt pot. One Boil Boss seafood boil seasoning bag weighs 1 pound, so six of them should do the trick. Check our seafood boil seasoning calculator to find the ideal ratio for your pot.

 

2. Get Your Gear

You can use the same crawfish boil equipment to make lobster, as the only difference is the size of your crustaceans! Here’s what you’ll need:

  • A big ol’ pot. A 100 qt pot can hold around 20 lobsters, give or take, depending on their size.
  • Crawfish burner to provide heat.
  • Crawfish pot cooler to prevent overcooking, improve flavor absorption, and keep Cajun lobster boils consistent from batch to batch.
  • Crawfish paddle to stir the pot and monitor the temperature.


3. Fill the Pot

Using the correct amount of water is crucial. Too much, and you’ll have weak flavor; too little, and the flavor will be overwhelming. 

  • 18" diameter pot: fill to 11" 
  • 19" diameter pot: fill to 9.75" 
  • 20" diameter pot: fill to 8.75" 
  • 21" diameter pot: fill to 8" 
  • 22" diameter pot: fill to 7.25"

Optional: Add 1/4 cup of sea salt for each gallon of water.


4. Bring the Water to a Rolling Boil

Light the burner, and set it to medium heat. Make sure you don’t turn it too high, as you don’t want the tank to freeze over.


5. Make Your Stock

The lobster boil is ready to kick off! Once the water is boiling, add your seasoning, celery, onions, garlic, and any other aromatics. Squeeze the juice of the lemons into the pot. You can toss the squeezed lemon rinds right into the pot or discard them.

Wait for 20-25 minutes or so. The flavors are all coming together, creating a stock. Taste it, and make adjustments if needed.


6. Time the Other Ingredients

Once your stock is complete (20-25 min., or to taste), it’s time to add the other ingredients. Don’t add everything at once! The goal is for everything to be perfectly cooked at the end, so plan when to add the ingredients for your Cajun lobster boil accordingly.

  • Potatoes typically need around 20 minutes to boil, depending on their size.
  • Corn on the cob typically needs 10 minutes.

There is the option to remove cooked potatoes and corn at this point in order to make room for the lobsters and also prevent overcooking these vegetables. Once the stock is back to a rolling boil, it's time to add the lobsters.

The amount of time you’ll need to boil the lobsters depends on their size.

  • 1 lb: 8 minutes
  • 1.25 lbs: 9-10 minutes
  • 1.5 lbs: 1-12 minutes
  • 1.75 lbs: 12-13 minutes
  • 2 lbs: 15 minutes
  • 2.25 lbs: 20 minutes
  • 3 lbs: 25 minutes
  • 5 lbs: 35-40 minutes

With so many lobsters, there’s bound to be size differences. Add your biggest lobsters first and your smallest ones last. Other factors to consider when planning out the timing for your lobsters are pot size, water volume, and the number of lobsters being cooked at once. 

Key Items to Consider

  1. Water Return Time: Start timing once the water returns to a rolling boil after placing the lobsters in. 
  1. Quantity of Lobsters: Cooking multiple lobsters at once can extend boiling time slightly due to the larger mass cooling the water initially. 
  1. Lobster Freshness: Fresh lobsters MAY require less time than frozen ones due to density differences. 
  1. Personal Preference: Adjust boiling times if you prefer firmer or softer meat but avoid overcooking to prevent a rubbery texture.

 

7. Stir and Monitor Temperature

Bring the water to a rolling boil to ensure the water temperature stays high enough when the lobsters are added. The water’s temperature for a lobster boil should be at 212°F. After adding the lobsters, allow the water to return to a rolling boil before starting your timer.

Use the Boil Boss Thermo-Paddle™ to stir the pot and track the temperature at the same time. Adjust the Boil Boss Triple Jet Burner as needed to maintain the correct temperature.

 

8. Cool the Pot

The lobsters are done when the shells are bright red and the antennae can pull out easily. The meat should be white, succulent, and perfectly cooked and juicy, not translucent and gelatinous. Once everything is cooked to perfection, use the Boil Boss cooling ring to cool the pot. Carefully pour the water out.

 

9. Serve and Enjoy

Traditionally, seafood boils are poured right onto a long, newspaper-lined table. You can take the same approach with a Cajun lobster boil, or you can simply use plates. We highly recommend the self-serve table approach, as it creates a sense of comradery as everyone digs in together. Don’t forget drawn butter, lemon wedges, and Louisiana hot sauce on the side!
