01 - In a saucepan, combine 3 cups water, 1½ cups long-grain white rice, 1 tbsp unsalted butter, and ½ tsp salt. Bring the mixture to a boil. Reduce heat to low, cover the saucepan tightly, and simmer for 15 minutes. Remove from heat and allow to stand, covered, for an additional 10 minutes. Fluff the rice with a fork before serving.
02 - In a large skillet or Dutch oven, melt 4 tbsp unsalted butter over medium heat. Add the finely chopped onion, green bell pepper, and celery. Sauté these vegetables until they are tender and softened, which typically takes about 7 minutes.
03 - Stir in 3 cloves minced garlic and cook for 1 minute until fragrant. Sprinkle 2 tbsp all-purpose flour over the sautéed vegetables. Cook, stirring constantly, for 3–4 minutes to form a blond roux, ensuring it does not burn.
04 - Gradually incorporate 1½ cups seafood or chicken stock into the roux, stirring continuously to prevent lumps. Add the drained 1 (14 oz) can of diced tomatoes, 2 tsp Cajun seasoning, ½ tsp smoked paprika, ½ tsp dried thyme, and 1 bay leaf. Bring the mixture to a gentle simmer.
05 - Reduce the heat and let the sauce simmer, uncovered, for 15 minutes. Stir occasionally until the sauce has thickened to the desired consistency.
06 - Introduce 1 lb peeled crawfish tails to the simmering sauce. Continue to simmer gently for 5–7 minutes, or until the crawfish are thoroughly heated through. Carefully remove and discard the bay leaf. Season the étouffée with salt, black pepper, and hot sauce to taste.
07 - Stir in 2 tbsp fresh chopped parsley and half of the sliced green onions into the étouffée.
08 - To serve, spoon the fluffy rice into individual bowls. Ladle the hot crawfish étouffée generously over the rice. Garnish with the remaining sliced green onions for a fresh finish.
