Frank's Crawfish

This crawfish dish is textbook Cajun cooking: a dark brown roux, the holy trinity of onions, celery, and garlic, crawfish tails simmered in fish stock and tomatoes, all ladled over steaming rice.

The roux is where this recipe lives or dies. Cooking butter and flour together for a full 10 minutes while stirring constantly builds a dark brown roux that adds a deep, nutty, almost smoky flavor you simply cannot get from a light roux. Stop stirring and it scorches in seconds. Keep going until it’s the color of dark peanut butter.

Adding the chopped onions, green onions, celery, and garlic directly into the hot roux lets the vegetables sweat in that concentrated fat and flour paste, absorbing all that toasted flavor while releasing their own moisture to loosen the roux.

The crawfish tails only need 20 minutes of simmering to cook through. They’re delicate and will turn rubbery if left on the heat too long. A touch of cayenne brings the heat that every good Cajun dish needs without overpowering the sweet, briny crawfish meat.

Pro Tips

• Stir the roux constantly and keep the heat low. A burnt roux tastes bitter and there’s no saving it. Start over if it smells scorched
• Use fish stock, not chicken broth. Fish stock keeps the flavor profile in the seafood family and gives the sauce a lighter, more delicate body
• Add the crawfish tails near the end of cooking so they stay tender and sweet
• This gets better as it sits. Make it ahead and reheat gently over low heat before serving

Variations

• Swap crawfish for shrimp if crawfish tails are hard to find in your area
• Add a splash of hot sauce at the table for those who want more kick
• Stir in a tablespoon of file powder just before serving for a more gumbo-like thickness and flavor
