Springtime in New Orleans means it’s crawfish season! Crawfish boils are such a treasured celebration in south Louisiana, especially if you get to take home some leftover crawfish! Use up those leftover crawfish tails in recipes like crawfish cream sauce, crawfish étouffée, crawfish Monica, crawfish bread, or these crispy fried crawfish po-boys!

What you’ll love about this recipe:


  • Lauren’s Take: Fried crawfish po’boys are a fun New Orleans inspired lunch or dinner. Cut them into small sections and serve them on a platter for a New Orleans themed dinner party. I like to swap mayo for remoulade sauce for extra zesty flavor.
  • Taste and Texture: Crispy fried crawfish on top of flaky french bread. The cold tomatoes, lettuce, and mayo provide the perfect balance of textures, temperatures, and flavors.
  • Time: Soaking the crawfish will take an hour, but after that crawfish fry up in 1-2 minutes. After that, just assemble the poboy.
  • Testing Notes: I tested this recipe with both buttermilk and a buttermilk alternative using milk and lemon juice mixed together which both worked well. 

What’s a Po’Boy?

A po’boy is a New Orleans style submarine sandwich. 

It’s made on a long loaf of flaky french bread. They can be topped with various fried seafood, roast beef, hot sausage, or cochon de lait (cajun pulled pork), but you can really put whatever you like on them. Some of the most popular seafood varieties are fried shrimp po’boys, fried oyster po’boys, and fried catfish po’boys. This crawfish po’boy is a fun version and perfect for crawfish season in the spring. 

Po’boys (poboy, or po-boy) get their name from the shortened version of “poor boy”. These sandwiches started in New Orleans almost 100 years ago, and have been popular ever since. You’ll find po’boys everywhere from nice restaurants to corner gas stations. 

Authentic New Orleans Tip

A “dressed” po’boy means it is topped with mayonnaise, shredded lettuce, sliced tomatoes, pickles, and mayonnaise in addition to the filling. 

Ingredients & Substitutions

Labeled Ingredients for fried crawfish po'boys.

See the recipe card below for the complete list of ingredients and measurements.

  • Crawfish tails – Use leftover crawfish tails from a crawfish boil, or frozen crawfish tails. It’s a great way to use leftover crawfish! 
  • Buttermilk – Buttermilk tenderizes the crawfish tails and helps the flour and cornmeal mixture to stick. Substitute buttermilk for an equal amount of whole milk plus 1 teaspoon of lemon juice. Mix together and let sit for a few minutes before using. 
  • Hot sauce – I love a vinegar based hot sauce like Crystal or Louisiana. 
  • Flour and cornmeal – I use a combination of all purpose flour and yellow cornmeal for a crispy crunchy coating. 
  • Salt – All salts are not created equal! Diamond crystal kosher salt is my favorite. It’s light and flaky, making it easy to season and difficult to over season. By volume, it’s a little less salty than fine sea salt and a lot less salty than table salt, so adjust accordingly. 
  • Seasonings – Garlic powder, onion powder, cayenne pepper, and black pepper are used to flavor the crawfish batter. 
  • Frying oil – Use a neutral high heat oil like vegetable oil or canola oil for deep frying.
  • French bread – The French bread in New Orleans really is like no other. It’s light, airy, chewy, and flakey without being dry. If you can get your hands on authentic New Orleans French bread like Leidenheimer’s, you’ll be in for a real treat. If not, any french bread loaf will do.
  • Toppings – The traditional toppings for a “dressed” po’boy are mayonnaise, shredded lettuce, slice tomatoes, and sliced pickles. 

Equipment Needed

Use an electric fryer to make frying easier. You can also use a deep cast iron skillet, cast iron dutch oven, or heavy stainless steel pot. Just make sure you are using a sturdy pot. 

A frying thermometer that clips to the side of the pot is super handy for keeping an eye on the oil temperature. A spider strainer is essential for easily scooping out fried food while transferring minimal oil.

Other items needed are paper towels and a baking rack to place the crawfish on after they come out of the fryer. Sprinkle some Diamond Crystal kosher salt after frying to properly season. 

Tips & Tricks

  • Fresh vs frozen crawfish. Frozen crawfish work perfectly well for this recipe. Make sure to defrost them just before making the recipe. 
  • Use hot oil! Frying with hot oil is essential for creating a crispy fried coating. If the oil isn’t hot enough, the batter can get soggy since it has to sit in the oil longer. Use a thermometer to check the temperature in between batches. 
  • Serve warm. To keep your crawfish warm, pop them in the oven for a few minutes while you work on assembling the po’boys.

Ingredients
  

For Crawfish

For Po’Boy

  • 1 loaf French bread
  • Mayonnaise
  • Shredded lettuce
  • Tomato
  • Sliced pickles
  • Hot sauce

Instructions
 

  • THAW: If your crawfish are frozen, soak the frozen package in cold water for about 15 minutes or place under cold running water. They should defrost quickly. Do not thaw ahead of time.
    1 pound crawfish tails
  • SOAK: Combine buttermilk and hot sauce in a container and stir, then add the thawed crawfish. Stir well to coat all the crawfish. Cover and refrigerate for 1 hour.
    ¾ cup buttermilk, 1 tablespoon hot sauce
  • PREP: While the crawfish are soaking, add flour, cornmeal, baking powder, salt, garlic powder, onion powder, cayenne pepper, and black pepper in a large zip top bag, seal, and shake well to combine. Slice tomatoes and shred lettuce.
    ½ cup flour, ½ cup cornmeal, 1 teaspoon baking powder, 2 teaspoons diamond crystal kosher salt, 1 ½ teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon cayenne pepper, 1 teaspoon black pepper
  • HEAT: When the crawfish are almost ready, add about 1 – 1½ inches of oil into a sturdy pot or deep skillet. Heat oil to 350°F (175°C).
  • SHAKE: Drain the buttermilk from the crawfish and gently squeeze out the excess liquid. Transfer the crawfish to the dry ingredients and shake well so all crawfish are coated. Use a spider strainer to lift the crawfish out and shake off excess flour mixture.
  • FRY: Working in batches, transfer battered crawfish to the oil and fry for 1-2 minutes, or until golden brown. Gently stir so they all fry evenly. Transfer fried crawfish to a paper towel lined plate or baking rack and promptly sprinkle with a pinch of salt. Continue until all crawfish are fried.
  • ASSEMBLE: Slice the french bread in half longways leaving one side attached. Layer both sides with mayonnaise, then add fried crawfish, lettuce, tomato slices, and pickles. Serve with hot sauce.

Notes

  • Frozen crawfish tails or leftover crawfish tails from a crawfish boil are both totally fine for this recipe.
  • Buttermilk substitute: mix ¾ cups whole milk with 1 teaspoon lemon juice together.  
  • Some of the cornmeal may fall to the bottom of the pot when frying, which is normal. 
  • Storage: Fried crawfish po’boys are best served fresh. If needed, store in the refrigerator for 1-2 days in an airtight container. Do not freeze.
  • Reheat in the oven on a baking sheet at 350°F (175°C) until warmed through.
