Substitutes for Crab Boil Seasoning with ratios

  1. 2Old Bay Seasoning Plus Extra Salt

    Different texture

    Use ¼ cup Old Bay + ¼ cup salt for every 4 quarts water

    The nearest ready-made blend, since Old Bay is built on the same celery seed, mustard, bay and paprika family.

    What changes
    Best for
    crab and shrimp boils, Maryland-style steamed crabs, boiled corn and potatoes, shrimp for shrimp cocktail

    Reliable and widely available, with two differences worth planning around. Old Bay is a fine powder rather than whole spices, so it clouds the water and clings to the shells, which is very much the point in a Maryland steam but looks murkier in a clear pot. It is also less hot than a Louisiana crab boil, so add a tablespoon or two of cayenne or red pepper flakes if you want that heat. Old Bay contains salt but not nearly enough to season a whole pot, so add the extra quarter cup.

  2. 3Pickling Spice Plus Cayenne and Salt

    Different taste

    Use ¼ cup pickling spice + 1 tbsp cayenne + ¼ cup salt for every 4 quarts water

    The most underrated swap, because pickling spice is already a whole-seed blend of mustard, coriander, dill, bay and peppercorns.

    What changes
    Best for
    crawfish and shrimp boils, crab, boiled corn and potatoes, court bouillon for fish

    Structurally almost the same product, and the whole seeds behave correctly in the pot. The trade-offs come from what pickling spice adds: cinnamon, cloves, allspice and sometimes ginger, which give the water a faintly sweet, mulled aroma that a crab boil does not normally have. Pick out the cinnamon sticks and the largest clove pieces if you want to avoid that. Add celery seed if you have any, since it is the note pickling spice is most likely to be short of.

  3. 4Liquid Crab Boil Concentrate

    Taste and texture differ

    Use 1 to 3 tsp liquid concentrate for every 4 quarts water, plus ¼ cup salt

    The small bottle of spice extract sold alongside the bagged blends, which seasons a pot with no solids at all.

    What changes
    Best for
    large crawfish and crab boils, adding heat to an already seasoned pot, keeping the water clear, topping up a pot mid-boil

    Extremely concentrated and the easiest thing on this list to overdo. It is essentially a spice oil extract, so a teaspoon can season several quarts and three tablespoons will make the pot inedibly harsh and medicinal. Start at the low end and taste the water. Because it contains no salt and no solids, you must add your own salt, and it lacks the pleasant texture and aroma of whole spices clinging to shells. Do not confuse the dosing on a liquid bottle with the dosing on a dry bag.

  4. 5Cajun or Creole Seasoning Plus Bay Leaves and Lemon

    Taste and texture differ

    Use ½ cup Cajun seasoning + 4 bay leaves + 2 halved lemons + salt to taste for every 4 quarts water

    A blend from the same region and the same flavour family, adapted for pot duty.

    What changes
    Best for
    shrimp and crawfish boils, boiled potatoes, sausage and corn, when Cajun seasoning is what you already have

    The heat, garlic and paprika all belong in a boil, so this tastes right in character. The gaps are the whole-spice aromatics: Cajun blends are ground and typically contain no dill seed, no mustard seed and little celery seed, so the water smells hotter and more herbal and less of that distinctive pickled-spice perfume. Bay leaves and lemon halves fill in a surprising amount. Cajun seasoning is salty, so add your salt gradually and taste the water before you commit.

  5. 6Heavily Salted Water With Lemon, Bay and Peppercorns

    Different taste

    Use ¼ to ⅓ cup salt + 4 bay leaves + 1 tbsp peppercorns + 2 halved lemons + 1 quartered onion for every 4 quarts water

    The honest minimum, and a reminder that salt does most of the work in any boil.

    What changes
    Best for
    shrimp, lobster and crab where you want the sweet shellfish flavour foremost, any kitchen with no blends at all

    Worth saying clearly: properly salted water plus lemon and bay produces genuinely good boiled shellfish, and undersalted water with an expensive spice blend produces bland shellfish. What you lose is the specific character of a crab boil, that mustard-and-dill pickling aroma and the chilli heat, so the result tastes clean and sweet rather than spicy and complex. If you have one extra spice, make it mustard seed, or failing that celery seed.

What is Crab Boil Seasoning?

Crab Boil Seasoning is Louisiana's seasoning for the pot rather than the plate: a heavily salted whole-spice blend of mustard seed, coriander, dill seed, celery seed, bay, black pepper and chilli, sold loose, in a muslin bag or as a liquid concentrate such as Zatarain's, and its job is to season the boiling water so that salt and flavour soak into shellfish through the shell.

Cooking tips

  • Salt the water far more heavily than feels reasonable. Roughly a quarter cup of salt per four quarts is a normal starting point for a boil, because the seasoning has to travel through a shell, and this is the single biggest difference between a good boil and a bland one.
  • Simmer the spices in the water for 10 to 15 minutes before the seafood goes in. Spices need time to give up their oils, and dropping them into the pot at the same time as the shrimp means most of the flavour never leaves the seeds.
  • Use whole spices where you can and bag them if you want a clean pot. Ground blends such as Old Bay or Cajun seasoning work, but they cloud the water and coat the shells, which suits a steamed crab better than a clear boil.
  • Let the shellfish soak off the heat after it is cooked. Turning the heat off and leaving shrimp for a few minutes or crawfish for 15 to 30 minutes in the seasoned water is when the flavour actually gets inside, and it is why restaurant boils taste seasoned all the way through.
  • Add corn, potatoes and sausage to the pot as well, both because they belong there and because they absorb a lot of seasoning, which means a pot with them in it needs more salt and spice than a pot of shellfish alone.

Frequently asked questions

Can I use Old Bay instead of crab boil seasoning?

Yes, and it is the most common substitute. Use about a quarter cup per four quarts of water plus a quarter cup of salt, since Old Bay alone does not contain nearly enough salt to season a pot. The two differences are texture and heat: Old Bay is a fine powder, so it clouds the water and clings to shells, and it is milder than a Louisiana-style crab boil, so add a tablespoon or two of cayenne or red pepper flakes if you want the burn.

What is the difference between liquid crab boil and the dry or bagged kind?

Liquid crab boil is a concentrated spice extract with no salt and no solids, dosed in teaspoons, and it is very easy to overdo. Dry loose blends and muslin bags contain whole spices and often salt, and are dosed in quarter-cups. They are not interchangeable by volume, and using a bag's worth of liquid will make the pot harsh and medicinal. If you swap between them, work from the package directions rather than the recipe's amount, and taste the water.

Can I just leave the crab boil seasoning out?

You can leave the spices out but not the salt. Boiled shellfish in unsalted water tastes flat and watery no matter how fresh it is, because the salt is what seasons the meat inside the shell. Season the water heavily, add lemon halves, a quartered onion and a few bay leaves if you have them, and you will eat well. The dish will taste of sweet clean shellfish rather than of a spiced boil, which for a good crab or lobster is a defensible choice.

Is crab boil the same as shrimp boil or seafood boil seasoning?

In practice yes, these are marketing names for the same style of blend and recipes use them interchangeably. All are built on mustard seed, coriander, dill seed, bay, black pepper, celery seed and chilli. Some crawfish-specific blends are hotter and saltier because crawfish are usually soaked longer. Use whichever you have, taste the water before the seafood goes in, and adjust the heat and salt to suit what you are boiling.

Can I use crab boil seasoning for pickling or canning?

Do not treat them as interchangeable in preserving. Crab boil blends are salted and often contain oil-based extracts, and swapping spice blends around in a canning or pickling recipe can change the salt balance and the acidity of the brine, which is a genuine safety issue rather than a flavour one. Never alter the vinegar, acid or salt levels of a tested canning recipe. Follow a tested recipe from a reliable source such as the National Center for Home Food Preservation, and use the pickling spice it specifies.
