It is similar in appearance to a pot pie and contains crawfish.

[3] Crawfish pie is prepared by making a roux with bell peppers, onions and celery, the "holy trinity" of Cajun cooking.

Seafood stock and cooked crawfish tails are then added to the roux before it is poured into a pie crust.

Spices and aromatics, including possibly garlic, black pepper, paprika and parsley, are also included in the roux.

[4][5] The dish is mentioned in the Hank Williams song "Jambalaya (On the Bayou)", along with other common Cajun dishes such as jambalaya and gumbo.
