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. Cook for 5-7 minutes, stirring often, until softened.
04 - Stir in the garlic and cook for 1 minute until fragrant.
05 - Add the diced tomatoes with juice, Creole seasoning, smoked paprika, cayenne, bay leaf, and a pinch of salt and black pepper. Mix well.
06 - 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.
07 - Add the shrimp to the sauce. Simmer for 3-5 minutes, or until the shrimp are pink and just cooked through. Remove from heat. Stir in chopped parsley and adjust seasoning with salt, pepper, and hot sauce if desired.
08 - Discard the bay leaf. Serve the shrimp étouffée hot over fluffy rice. Garnish with green onions, extra parsley, and lemon wedges if desired.
