01 - Rinse the rice under cold water until the water runs clear. In a medium saucepan, bring 2 cups water and 1/2 tsp salt to a boil. Stir in the rice, reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let rest, covered, for 10 minutes. Fluff with a fork before serving.
02 - While the rice cooks, melt the butter in a large, heavy-bottomed skillet or Dutch oven over medium heat. Whisk in the flour and cook, stirring constantly, for 3-4 minutes until the mixture turns a light caramel color, making a blonde roux.
03 - Add the onion, bell pepper, and celery to the roux. Cook for 5-7 minutes, stirring often, until the vegetables are softened and fragrant.
04 - Stir in the garlic and cook for 1 minute until fragrant. Add the diced tomatoes with juice, Creole seasoning, smoked paprika, cayenne, bay leaf, and a pinch of salt and black pepper. Mix well to incorporate.
05 - Gradually add the stock, stirring constantly to avoid lumps. Bring to a gentle simmer and cook for 15 minutes, stirring occasionally, until the sauce thickens nicely.
06 - Add the shrimp to the sauce. Simmer for 3-5 minutes, or until the shrimp are pink and just cooked through. Remove from heat immediately to prevent overcooking.
07 - Discard the bay leaf. Stir in chopped parsley and adjust seasoning with salt, pepper, and hot sauce if desired. Serve the shrimp étouffée hot over fluffy rice. Garnish with green onions, extra parsley, and lemon wedges.
