A seafood boil is the ultimate way to feed a crowd: shrimp, crab, lobster, and clams tumbled together with corn, potatoes, and sausage in a spiced, buttery broth, then poured out on the table for everyone to dig in. It looks impressive, but it is really just one pot and a little timing. This guide walks you through exactly what to buy, the order to add everything, and how to nail it.

Quick Answer: To make a seafood boil, simmer potatoes, sausage, and corn in a seasoned broth, then add the seafood in order of cook time: lobster and crab first, then clams and mussels, and shrimp last. The rule is to add each ingredient by how long it takes to cook, longest first, so nothing overcooks. A classic boil combines shrimp, crab legs, lobster, clams, and mussels with corn, potatoes, and sausage, all tossed in garlic butter and Old Bay seasoning.

This guide covers what goes in a seafood boil, how much to buy per person, the exact order and cook times for each ingredient, how to make the broth and butter sauce, and a full recipe you can scale to any crowd.

What Is a Seafood Boil?

A seafood boil is a one-pot feast where shellfish and vegetables are boiled together in a heavily seasoned broth, then drained and served family style, often poured straight onto a paper-lined table. It has roots in coastal cooking across the United States. A Low Country boil from the Carolinas and Georgia is milder and built around shrimp, sausage, corn, and potatoes, while a Cajun or Louisiana boil is spicier and often features crawfish or crab. At home you can mix and match whatever seafood you love.

What Goes in a Seafood Boil

A great boil balances a few types of seafood with hearty add-ins that soak up the broth. You do not need all of these, but a good spread includes two or three kinds of seafood plus the classic vegetables.

The Seafood

The Add-Ins

Small red or baby potatoes, corn on the cob cut into pieces, and smoked sausage such as andouille or kielbasa are the classic trio. They stretch the meal, soak up the seasoning, and make the boil a complete dinner. Onion, garlic, and lemon go into the broth for flavor.

How Much Seafood to Buy Per Person

A boil is meant to be generous. Use this as a starting point per person, then adjust up for big appetites:

Ingredient Per Person
Shrimp 1/2 pound
Crab legs 1/2 pound or 1 cluster
Lobster 1 tail
Clams and mussels 1/2 pound
Sausage 1/4 to 1/2 pound
Corn 1 to 2 ears
Potatoes 1/2 pound

You do not need every type of seafood for each guest. Pick two or three proteins and spread them across the table. For a full breakdown by seafood type, see our seafood portion guide.

What You Need

The only special equipment is a big pot. Use a large stockpot of at least 10 to 12 quarts, ideally with a strainer basket so you can lift everything out at once. For a large crowd, an outdoor propane burner keeps the heat and steam out of the kitchen, or you can split the batch between two pots. You will also want a slotted spoon or spider, tongs, and plenty of napkins.

The Order to Add Everything

This is the secret to a perfect boil. Everything cooks in the same pot, but each ingredient goes in at a different time so it all finishes together without overcooking. Always add the longest-cooking items first.

  1. 1Build the brothFill the pot about halfway with water. Add seasoning such as Old Bay or a crab boil mix, halved lemons, quartered onion, and smashed garlic. Bring it to a rolling boil.
  2. 2Potatoes firstAdd the potatoes and boil for about 15 minutes, until they are almost tender. They take the longest, so they lead.
  3. 3Sausage and corn nextAdd the smoked sausage and corn and cook for another 5 to 7 minutes.
  4. 4Then lobster and crabAdd raw lobster tails and crab and cook about 5 to 8 minutes. If your crab legs or lobster are already cooked, add them near the very end just to heat through.
  5. 5Clams and musselsAdd the clams and mussels and cook about 5 minutes, until the shells open. Discard any that stay shut.
  6. 6Shrimp lastAdd the shrimp and cook just 2 to 3 minutes, until pink and opaque. You can also turn off the heat and let them sit in the hot broth for a few minutes. Then drain and serve.
Shrimp go in last and cook in just 2 to 3 minutes until pink and opaque

Seafood Boil Cook Time Chart

Here is the timing at a glance. Add each ingredient in this order and the whole boil comes together in about 30 minutes.

Ingredient Add Order Cook Time
Potatoes (small) 1st 15 to 20 min
Sausage 2nd 10 to 12 min total
Corn 2nd 7 to 10 min
Lobster tails (raw) 3rd 5 to 8 min
Crab legs (pre-cooked) 3rd or last 5 to 8 min to heat
Clams and mussels 4th 5 min, until open
Shrimp Last 2 to 3 min

Most snow crab and king crab legs are sold already cooked, so they only need to be heated through. Raw crab in the shell takes longer, around 15 to 20 minutes.

How to Make the Broth and Butter Sauce

The broth is where the flavor starts. Season the water generously with Old Bay, a Cajun or crab boil blend, salt, lemon, onion, and garlic. It should taste bold, since the seafood and vegetables absorb it as they cook.

Many people also serve a garlic butter sauce over the drained boil. To make it, melt a stick or two of butter, then stir in minced garlic, a spoonful of Old Bay or Cajun seasoning, a squeeze of lemon, and chopped parsley. Pour it over everything just before serving, or set it out for dipping.

Tips for the Perfect Boil

  • ✓Use the biggest pot you have so everything cooks evenly, or split it between two pots
  • ✓Season the water boldly, since the food absorbs the flavor as it cooks
  • ✓Add seafood by cook time, longest first, and shrimp last
  • ✓Do not overcook, pull shrimp when pink and clams and mussels when the shells open
  • ✓Thaw frozen seafood first for the most even cooking
  • ✓Discard any clams or mussels that do not open after cooking

How to Serve a Seafood Boil

The fun of a boil is the presentation. Line a table with butcher paper or newspaper, drain the pot, and pour everything out in a big steaming pile. Scatter extra lemon wedges, set out bowls of garlic butter and cocktail sauce, and give everyone a bib, a cracker for the shells, and lots of napkins. Serve with crusty bread and cold drinks.
